Fixing Mate Adwaita theme problems on Debian and Ubuntu Linux

Wednesday, October 25th, 2017

fixing-mate-adwaita-theme-problems-on-Debian-Ubuntu-Linux-the-actual-problem-screenshot

After  trying out GNOME 3.2.x enough and giving it enough chance I've decided to finally migrate to Linux Mate graphical environment (the fork of gnome 2 for modern PCs).

I have to say I'm running Debian 9 Stretch on my upgraded Thinkpad R61, after 2 / 3 days upgrade operations from Debian 7 to Debian 8, from Debian 8 to 9.

Just Migrated to Mate all looked fine, but just as I wanted to make the look and feel identical to GNOME 2, I played with Appearance because I wanted to apply theme Adwaita the one, the one so popular since the glorious times when GNOME 2 was a king of the Linux Desktop. 

To add additional themes to MATE, I've installed gnome-themes-standard package, e.g.

apt-get install  --yes gnome-themes-standard

This package provides a number of Themes I could choose from and one of them is Adwaita Not surprisingly, I faced a theme issue
it complains about window manager theme "Adwaita" missing.

Using the example for Adwaita mate-appearance-properties gives, I believe this is the "Proper" way to fix it, so do the following in order;

The quick and dirty way when using it

  • Select Adwaita theme
  • Click on Customise

     

    • Select the Window Border tab
    • Select window border theme "TraditionalOk" and close

 

A Permanent Fix to the Adwaita missing its Theme Manager using terminal / console

I found that all I had to do to resolve the issue permanently was to do this;

vim /usr/share/themes/Adwaita/index.theme

And change at the bottom where it says 

MetacityTheme 

to say 

TraditionalOk 

instead of Adwaita.

I know why this works, I just do not know why Adwaita can't use its own Metacity theme without issues, aside from what the kind people at #gnome@irc.freenode.net said about Adwaita previously relying on Mutter.

Feel free to tell me if up explained did not work for you or if you have a better way to deal with the Adwaita missing manager theme issueso far I believe the  problem is resolved correctly.

How to configure Nautilus (Linux application like Windows Explorer) to work with standard Windows button + E On Linux GNOME en Mate

Monday, October 9th, 2017

how-to-configure-nautilus-linux-applicatoin-to-act-like-windows-explorer-make-windows-button-work-in-GNOME-and-Mate
As an ex-Windows user I'm still addicted to Windows User brainwashing as an ex-victim of Windows 95 / 98 and XP:), so I tend to love very much and its still hard for me to forget some major Key Binding (Windows Key Combinations).

On every new Desktop Linux I install, I have the habit to configure few great key combination shortcuts that makes my digital life much easier.
I use usually as a graphical environment GNOME and recently switched to MATE (GNOME 2 fork, cause GNOME 3 is totally messed up and unworthy to me), that's why this article is targetting this two Linux GUI envs, I'll be glad to hear in article comments for any other useful key bindings and how to configure similar key bindings for other Major Linux graphical environments (Cinnamon, KDE Plasma, XFCE, LXDE).

 

1. Configuring Lock Screen (Win button + L), Open Explorer(Win button + E), View Desktop (Win + D) in MATE graphic env

 

 

———  WINDOWS BUTTON, OFTEN USED KEY SHORTCUTS ———

Windows + E – Open new Windows File Explorer 

Windows + L – Lock Computer

Windows + M – To minimize All Windows

Windows + D – Show Desktop (similar to Windows +M though it doesn't switch to Desktop)

Win – + / – To Maginfy Text and Windows

Shift + Win + Left/Right Arrow – (In Windows if you have multiple monitors connected to the same computer lets say Right Monitor and Left, that combination switches between left monitor and right monitor)


——————————————————————–

 

The list goes on but I'm not used to all of them, I'll stop here and continue on with how to remake some of my favourite Windows keybindings in Gnu / Linux

Either run it from Menus:
 

System -> Settings -> Hardware -> Keyboard Shortcuts


Or run command

 

$ mate-keybinding-properties

 

howto-gnome-mate-remap-shortcut-keybinding-keys-mate-keybinding-properties


After rebinding the Windows: 
– Lock Screen and Open New Nautilus Explorer Window (Home folder) variable to be invoked with Windows button, the result
is as that:

howto-gnome-mate-remap-shortcut-keybinding-keys-mate-keybinding-properties
 
 

Scroll down Mate Keyboard shortcuts and you'll find

also how to configure Windows Button and D Key Combination, following 2 more screenshots showing how to do it note that MOD Key appears once you press Windows Keyboard Key + something (e.g. MATE recognizes MOD Key as Win Key):

Before the change to bind Win Key + D to work:

mate-how-to-make-desktop-view-open-with-standard-windows-button_and_d-combination-linux-debian

When configured Win Button + D looks like so:

mate-how-to-make-desktop-view-open-with-standard-windows-button_and_d-combination-linux-debian-1

2. Configuring Lock Screen (Win button + L), Open Explorer(Win button + E), View Desktop (Win + D) in GNOME

Usually in GNOME until > version 3.X.X (in older GNOME graphic environment access to KeyBinding Properties was done via:

 

System -> Preferences -> Keybord Shortcuts -> Add ->


In fallback gnome with Metacity (if installed along with GNOME Desktop 3.2.X environment to access Key Bindings):

d

System->Apps->Metacity->global_keybindings  

 

Also it is possible to remap keys via dconf-editor, I've written a small article earlier explaining how to remap Screenshotting buttons with dconf-editor but the example could be easily adapted, so you can edit almost everything.

Besides that you can use a command to run the keyboard configuration (in older GNOMEs) via:

 

linux:~$ gnome-keybinding-properties

 

Just for information for those who might know, many Key Binding interesting options are available via gnome-tweak-tool, so if you don't have it yet install it and give it a try:

 

linux:~# apt-get install –yes gnome-tweak-tool


As you can see, there are plenty of options to make Win (key) to act like Alt (key):

linux:~# gnome-tweak-tool
 

gnome-tweak-tool-make-win-key-to-behave-like-alt-key-howto 


After configuring the changes enjoy your WINDOWS Button + L, WINDOWS + E and WINDOWS + D WORKING AGAIN HOORAY !!! 🙂 
 

 

3. Most used shortcuts in Gnome and Nautilus 
 

Below are most used shortcuts thanks to LinuxQuestions Forum for providing them

Howdy! I thought that it would be useful to post a practical selection of shortcut keys for GNOME (the Desktop Environment) and Nautilus (the File Manager) and some information about customizing shortcut keys in Ubuntu. I wrote it especially for Ubuntu beginners, but I hope it will prove useful for all. 

 

2.1 GNOME/Nautilus shortcut keys – Very useful for the keyboard maniax like me :):
 

Ctrl-H: show hidden files

Ctrl-N: new window

Ctrl-Shift-N: create new folder

Alt-Home : jump to home folder

Alt-Enter : file / folder properties

F9 : toggle side-pane

Alt-F1 : launch applications menu

Alt-F2 : launch "run application" dialogue

Ctrl-Alt – Right/Left arrow : move to the next virtual desktop

Ctrl-Alt-Shift – Right/Left arrow : take current window to the next virtual desktop

Ctrl-Alt-D: minimize all windows, and gives focus to the desktop. 

Alt-Tab: switch between windows. When you use these shortcut keys, a list of windows that you can select is displayed. Release the keys to select a window. 

Ctrl-Alt-Tab: switch the focus between the panels and the desktop. When you use these shortcut keys, a list of items that you can select is displayed. Release the keys to select an item. 

Ctrl-Alt-L: lock the screen (tested only in Ubuntu) 

Ctrl-L: shortcut for opening locations-by default the path is the home folder*
/ : same as Ctrl-L but has the root (/) as default path* (shortcut found on here)
* both shortcuts can be used while you are on the desktop (no window active)

Ctrl-T : move to trash (in Nautilus)
Quite dangerous key combination because many of us are used to press these keys in order to open a new tab. Because we all delete items using the Delete key, I recommend to deactivate this shortcut key. To do that, go to System » Preferences » Appearance » Interface. Select Editable menu shortcut keys and close the dialog box. Click on the Edit menu in the File Browser. Click the Empty Trash item (it has Ctrl-T as the keyboard shortcut) Press the Delete key to get rid of the shortcut.
You can find all GNOME shortcut keys here

 

2.2 How to create a custom hotkey to launch whatever application you want in GNOME
 

As an example, we will set a lock-screen shortcut.


Open "gconf-editor" as the user as you're logged in in GNOME (typing gconf-editor in the terminal or "Run Application").
 

Go to apps > metacity > keybinding_commands


Here we have a list of twelve slots for commands.

 

Double click on e.g. "run_command_1" 

In Key Value Type in the name of the application or command you want to launch (e.g. gnome-screensaver-command –lock).

 

Go to apps -> Metacity -> global_keybindings 

Double click on e.g. "run_command_1" 
Change the key value to whatever key combination you like (e.g. <Ctrl><Alt>L).Press "Ok".

 

2.3.How to create/change GNOME shortcuts
 

 

Click on System -> Preferences -> Keyboard Shortcuts


Click the action in the list and press Enter. 
Press the new key or key combination you want to assign to the action. (To clear a shortcut, press the Backspace key)

 

Hope it helps, Enjoy Life .;)

How to boost Linux sound volume over 100% – Maximum Volume Audio Boost in GNOME and KDE

Friday, September 29th, 2017

how-to-boost-increase-sound-in-linux-audio-stack-illustrated
 

How to boost Linux sound volume over 100% to 150% or 200% ?


If you have recently migrated to Free Software Operating System Fedora,  Ubuntu or Debian GNU / Linux, OpenSuSE with GNOME / Mate / KDE / Xfce graphical environment, you might encounter that sometimes when using your computer for Multimedia the audio sound produced and streamed to the Sound Card is very low, so low that it prevents you from comprehending what the video, music etc. played says or you have to strain hardly your ears to hear what is to be said.

Let me illustrate what I mean, say  you watch an educational video  within Firefox / Opera (browser) in Youtube or listen some songs playlist in Vimeo.COM and the Sound on the follow up video suddenly becomes so low that you can't understand what the Coach or Instructor on the video is saying, or it could be a low sound within a Video downloaded on the PC and watched with Mplayer or VLC (Movie Players),
or lets say you listen MP3 / MP4 / OGG Song, S3M with mpg123 (in console) or with Qmmp (a graphical mp3 Windows WinAmp like player for Linux similar to good old XMMS Player).

So what is to be done to increase the audio volume from your Linux powered Notebook over 100% ??

I assume you already tried everything possible such as using aumix (Console / Terminal based tool) to boost your Sound Output to maximum and you also checked Gnome Alsa Mixer to make sure the Volume status is set to maximum but nothing helped as the sound produced is way lower behind you wish too.

By the using alsamixer command might help sometimes to increase the Linux sound volume a little bit but still you can't boost over 100% with it.

alsamixer-linux-screenshot

Apple Mac OS X users have surely experienced similar issues and are probably aware of the existence of a Trial (paid) application Boom 2 – A Mac OS Sound Volume Booster with Advanced Audio Equalizers and Effects but is there some similar Sound Increaseing software over the standard maximum 100% Volume for Linux?

Well yes, there is its called PavuControl (PulseAudio Volume Control)

 

linux-desktop:~# apt-cache show pavucontrol|grep -i description -A 3
Description-en: PulseAudio Volume Control
 PulseAudio Volume Control (pavucontrol) is a simple GTK+ based volume
 control tool (mixer) for the PulseAudio sound server. In contrast to
 classic mixer tools this one allows you to control both the volume of

Description-md5: c43956d9d08801fbaa1a405d7b6a9e6b
Homepage: http://freedesktop.org/software/pulseaudio/pavucontrol/

 

To run it run pavucontrol from terminal program:

linux-desktop:~$ pavucontrol

how-to-boost-linux-sound-in-gnu-linux-fedora-debian-ubuntu-program-application-to-increase-sound-over-hundred-percents

If pavucontrol command is not present on your Linux install it with apt as usual:
 

linux-desktop:~# apt-get install –yes pavucontrol


Note that PavuControl is using PulseAudio Linux Sound Streaming server to boost the Audio and not the ALSA (Advanced Linux Sound Server – which receives sounds from various applications and paralyzes them in different sound channels). 

 

 

If you want to prevent the Volume Boost audio increase over 100% to lets say either the 150% percentages, the maximum pavucontrol gives you can do that by including the /usr/bin/pactl command (which is a part of pulseaudio-utils package) to /etc/rc.local (be sure you include the command in rc.local before exit 0 command)

To give it a test you can manually run from terminal:

linux-desktop:~$ pactl — set-sink-volume 0 150%

 


You will notice the audio output sound increased immediately Note that the Sound boosting in Linux can be done over 150% to lets say 200% or 250 out of the normal maximum, and you can test 200% if you have a nice big speakers connected to your Computer to piss off your wife :), e.g. run:

# !!!!!!! RUN BELOW COMMAND AT YOUR OWN RISK AS THIS MIGHT DAMAGE YOUR COMPUTER OR EXTERNAL SOUND SPEAKERS !!!!!!

 

linux-desktop:~$ pactl — set-sink-volume 0 250%

How to enable Control Alt Backspace to Kill X server on Debian / Ubuntu Linux

Thursday, September 28th, 2017

kill-X-server-switch-revert-back-to-ctrl-alt-backspace-howto
Being a long time GNU / Linux user, I've been quite dissatisfied for the fact that in latest Debian and Ubuntu Linux, the default Key combination to Kill X (CTRL + ALT + BACKSPACE) is no longer working.

Though nowdays Xorg (XServer) is pretty stable it still happens from time to time for some application to overload the PC badly and make Gnome or KDE environment little or no responsive at all and here comes the goody CTRL + ALT + BACKSPACE it is pretty much  like  (CTRL + ALT + DEL) did restarted the computer in DOS and earlier Windows OS-es once the environment became unusable with the only difference that just Xorg server is restarted and the other using programs that are in background work just like they used to. 

CTRL + ALT + Backspace is a great thing to use especially if you're running some homebrew server and you use it both as a Server with some few little websites and as a Desktop environment to browse the net and do basic stuff.

So here comes the question how to make the CTRL + ALT + BACKSPACE keyboard combination be killing Xserver like in the good old days?

The easiest way to do it interactively in ncurses interface is by  running:

 

root@noah:~# dpkg-reconfigure keyboard-configuration

 

If somehow on the machine you don't have dpkg-reconfigure or you prefer to do set CTRL + ALT + BACKSPACE Kill Switch manually edit /etc/default/keyboard 

inside change value of

 

XKBOPTIONS="terminate:ctrl_alt_bksp" 

 

like shown below file:

root@noah:/home/hipo# cat  /etc/default/keyboard

# KEYBOARD CONFIGURATION FILE

# Consult the keyboard(5) manual page.

XKBMODEL="pc105"
XKBLAYOUT="us"
XKBVARIANT=""
XKBOPTIONS="terminate:ctrl_alt_bksp"

BACKSPACE="guess"

The configuration should be working across Debian 7, 8, 9 as well as Ubuntu 12 ..14 .. 16 and hopefully in future releases too, just as many other Linux distributions like Mint etc. the Xserver Kill Switch setting should be located in same file.

Finally if even after that change the Control Alt BackSpace Kill Switch sequence refuses to work in GNOME Desktop environment, it might be due to a local setting typical for GNOME and this should be fixed via the good known gnome-tweak-tool

So GNOME users should run it from command line and check the setting there, e.g.:

 

$ gnome-tweak-tool


You should check:


 

Typing -> Kill Sequence to Kill the X Server

 


it should look like shown in below screenshot:

Configure GNOME 3 to support dual / multiple monitors / Fix broken workspaces

gnome3 dual 2 monitors not showing right workspace display issue how to fix

If you're using some GNU / Linux distribution with GNOME 3 and you would like to show output of screen in two connected Monitors to the machine you will stumble upon really unusual behavior. For some unknown reason GNOME environment developers make second monitor to keep fixed on on First Workspace, so whether you try changing Desktops to second / third etc. Virtual Desktop you end up with your secondary monitor focused on Workspace 1. Logically the use of Dual monitor configuration is to show all GUI output identically on both monitors so this behavior is "wrong" ….

Fortunately there is setting that control this weird behavior in GNOME through gconf-editor and simply changing that switches monitors to show properly.

To fix it:

Start Run Command or Press Alt + F2 to invoke GNOME Run menu

Navigate to registry path Desktop -> Gnome -> Shell -> Windows and Uncheck selection on workspaces_only_on_primary 

gconf-editor-gnome3-fix-dual-monitor-improperly-showing-workspaces

To make new changes take effect its necessary to Log Off or Restart PC.

There is another easier way for command line oriented people to apply changes without using / having installed gconf-editor by issuing:

gsettings set org.gnome.shell.overrides workspaces-only-on-primary false

How to disable GNOME popup notification in Debian Wheezy Linux

Friday, August 2nd, 2013

how to disable remove GNOME 2 / 3 popup e mail notification  Debian Ubuntu Linux screenshot

I found it very annoying to have a pop-up notification every time I receive a new email it is just pointless there especially, when I already use Thunderbird (IceDove) to fetch my email via pop3. This pop-up notification though planned to be useful messes with my Desktop and breaks the habit on how I'm used to old GNOME interface…. I remember same popup notification was present on older Fedora releases (back in time when I used Fedora Linux for my Desktop).

disable Gnome popup notification new email Debian GNU Linux Wheezy 7 screenshot

My logical guess was in order to disable popup notification in GNOME 3 I had to tamper with gconf-editor. In gconf-editor config database there is:

Apps -> Notification daemon

Problem it is not possible to turn it off. Only available change options are:

default-sound, popup_location, sound_enabled, and theme

After some time of try / fail attempts I found the solution on linuxquestions forum, its quite raw solution but it works, all I had to do is change permissions of /usr/lib/notification-daemon/notification-daemon;

debian:~# chmod 0000 /usr/lib/notification-daemon/notification-daemon

Another thing that is handy to disable is POP UP Window with warning that you have low disk space on Hard Drive.

The warinng for Disk space is very annoying and popups up on every GNOME boot. Actually the hard drive with Low disk space is and old mounted partition in NTFS and I only use it to read data.

Here is how to disable HDD Notification Warnings in GNOME:

debian:~# chmod 0000 /usr/lib/gnome-disk-utility/gdu-notification-daemon

Remove password prompt on GNOME Shutdown / Restart on Debian and Ubuntu Linux

Saturday, June 1st, 2013

It is ultra annoying, that in newest Debian and Ubuntu releases with GNOME 3 Desktop environment on every shutdown or restart you need to type in Super User (root) password, to authorize shutdown / restart.

Generally prompting for root password on GNOME restart is obviously a good think from security point of view, but from usability one – especially on notebooks it is useless annoyance…

So after changing this behavior I came up with this tiny article on how to get rid of GNOME Shutdown / Restart password prompt.

There is a click button (on left of Auth prompt on Shutdown showing URL to XML policy rule from where this behavior is controlled. A really good hint to where to look for to change those annoying behavior…

 Here is how to change this new annoying behavior to old GNOME 2 default restart with no root password prompt .
linux:~# gedit /usr/share/polkit-1/actions/org.freedesktop.consolekit.policy
 

Find in XML source sections:
 

Restart the system when multiple users are logged in System policy prevents restarting the system when other users are logged in no auth_admin_keep
Stop the system when multiple users are logged in System policy prevents stopping the system when other users are logged in no auth_admin_keep

To change Restart and Shutdown GUI behavior to not prompt for password, you need to modify in above code:

auth_admin_keep
To:

yes

After changes both sections should look like so:

<action id="org.freedesktop.consolekit.system.restart">
<description>Restart the system</description>
<message>System policy prevents restarting the system</message>
<defaults>
<allow_inactive>no</allow_inactive>
<allow_active>yes</allow_active>
</defaults>
</action>

<action id="org.freedesktop.consolekit.system.restart-multiple-users">
<description>Restart the system when multiple users are logged in</description>
<message>System policy prevents restarting the system when other users are logged in</message>
<defaults>
<allow_inactive>no</allow_inactive>
<allow_active>yes</allow_active>
</defaults>
</action>
 

That's all you finally get rid of the annoying prompt for root password. Enjoy 🙂

Save ( Extract ) only images from PDF files on GNU / Linux in console and in GNOME nautilus

Wednesday, November 14th, 2012

extract only pictures / ( images ) from PDF / PDF save only images

Some time ago, I've blogged how it is possible to dump a PDF individual pages into JPG / PNG etc. pics.

Today interestingly, I've learned it is possible to not only dump single or whole PDF document pages into pictures but also to selectively dump only the pictures contained within  PDF file into JPEGs.

Dumping only PDF (contained) images into external JPEG files is doable on GNU / Linux with pdfimages.

1. Extracting pictures from PDF in text console / terminal

pdfimages is part of poppler-utils deb package, if for some reasons you don't have pdfimages on ur system install poppler-utils with;

apt-get install --yes poppler-utils

To extract images of a certain PDF from terminal / console command line it is as simple as:

pdfimages -j pdf-file-name.pdf prefix-of-output-file

pdfimages
will extract all pictures, but bear in mind with some PDF versions it might incorrectly dump some text pages thinking it is pictures too. Also with some PDFs which contain scanned very old paper documents (as pictures) trying to force pdfimages to dump it will just provide you with all pages of the PDF in JPGs. Option -j instructs dumping images from PDF in JPEG picture format, whether the second argument will save pictures in files like: prefix-of-output-file-000.jpg, prefix-of-output-file-001.jpg, prefix..-file-002.jpg etc.

2. Adding GNOME nautilus capability to extract images from PDF files

Enabling extracting images in nautilus is possible with one non-default nautilus plugin  nautilus-scripts-manager

nautilis-scripts-manager is very nice, but I'm sure many Linux users did not know it yet. It makes possible to add any custom shell script that does an opeartion to be visible in nautilus via one extra menu Scripts. As not normally needed on most Linux distributions, it is not installed by default so you have to install it:

noah:~# apt-get install --yes nautilus-scripts-manager

Below is a Screenshot from my nautilus Scripts menu (my locale is in Bulgarian), so Scripts word is in Cyrillic "Скриптове" 🙂

nautilus scripts menu screenshot - allowing users to add custom shell scripts to run in GNOME desktop extract pictures from PDF Linux

After nautilus-scripts-manager is installed. To use it in your user home directory you will have to create ~/.gnome/nautilus-scripts, i.e.

$ mkdir ~/.gnome2/nautilus-scripts

Any script placed inside can be then invoked via the newly appeared nautilus "Scripts" menu. Thus to use extract_images_from_pdfs.sh from GUI place it there.

Download the following extract_images_from_pdfs.sh shell script

$ cd ~/.gnome2/nautilus-scripts
$ wget -q http://www.pc-freak.net/files/extract_images_from_pdfs.sh
$ chmod +x extract_images_from_pdfs.sh

If you prefer to copy paste script content:

$ cat ~/.gnome2/nautilus-scripts/extract_images_from_pdf.sh
#!/bin/bash
# Extracts image files from PDF files
# For more information see www.boekhoff.info
## Added check for $1 existence and $1_images dir
existence check by hip0
# http://www.pc-freak.net/blog/
if [ $1 ]; then
if [ ! -d ./$1_images ]; then
mkdir -p ./"$1_images"
fi
pdfimages -j "$1" ./"$1_images"/PDFimage
gdialog --title "Report" --msgbox "Images were successfully extracted!"
exit 0
fi

 

Well that's all. Once you select a PDF and you click with last mouse button on it selecting Scripts -> extract_images_from_pdf.sh a new directory containing the filename prefix of the selected PDF with _images will appear. For exmpl. if pictures are extracted from PDF named filename.PDF in same directory where the file is present you will get new filename_images folder with all pictures dumped from the PDF.

I've learned about pdfimages existence from Sven Boekhoff's blog which btw has plenty of interesting other stuff

 

Well that's it hope this helps, someone. Comments are welcome 🙂

How to make GNOME 3 Desktop icons to work as in GNOME 2 on Debian GNU / Linux

Saturday, February 4th, 2012

If you're using Debian GNU/Linux wheezy/sid, you have already figured out GNOME3 settings to start GNOME in Classic mode (like in GNOME 2), starts gnome in a mode where the desktop is not showing the usual Computer, Home, Trash etc.

Besides that in that strange back-compitability Classic GNOME mode its impossible to add any program as a link in desktop like in the good old GNOME 2.

Thanksfully this abusive behaviour of the backwards compitability mode is easily fixable by two simple steps, here they are:

1. Install gnome-tweak-tool – (Tool to adjust advanced configuration settings for GNOME

root@debian:~# apt-get install gnome-tweak-tool

2. Start gnome-tweak tool

Press ALT+F2 and run gnome-tweak-tool or run it via xterm / gnome-terminal:

moonman@Moon:~$ gnome-tweak-tool

Change in Desktop, Have file manager handle the desktop the settings to ON

gnome-tweek-tool Debian GNU Linux wheezy sid screenshot

gnome-tweak-tool Debian wheezy/Sid GNU Linux screenshot handle desktop on

Once the Screenshot Handle Desktop is set to ON, further drag and dropping any application to the Desktop will be working.
Something really irritating is that launching applications in GNOME 3 does not work properly if you just press ALT+F2 and type in lets say gnome-terminal , to work around this weirdity you will have to install gnome-shell package.
