1. Gnome Appearance modify command  in Linux instead – Intro

It is always handy to do stuff in console and as a GNU / Linux long time GNOME user I found it interesting to share here some nice tips on how Theme could be changed using command line.

Why would you ever want to change themes through console / Terminal? Well lets say you have to administrate remotely a bunch of GNU / Linux Desktop machines and you have to change themes simultaneously on a multiple hosts, changing theme using the command line then comes really handy.

Besides that in GNOME 3.X.X branch with Unity (yackes) if you have chosen to use GNOME (Flashback /Fallback) or Mate you might find it difficult to change some specifics of the default theme, that is especially true for GNOME (flashback) Fallback like me.

If you heard GNOME Flashback but you never used i and wonder what it is I think it is worthy to say few words about it:

GNOME Flashback is a session for GNOME 3 which was initially called "GNOME Fallback", and shipped as a stand-alone session in Debian and Ubuntu. It provides a similar user experience to the GNOME 2.x series sessions. The differences to the MATE project is that GNOME Flashback uses GTK+ 3 and tries to follow the current GNOME development by integrating recent changes of the GNOME libraries. The development currently lags behind a little but a lot of progress has been made in bug fixing lately. So in short GNOME Fallback is for anyone who wants to stick to GNOME 2.X interface but doesn't want to stick to Mate and wants still to use some more graphical goodies that comes with GNOME 3.

In MATE nowadays there is possibility to relatively Easy add / change appearance and add new themes, there is also the graphical tool called Appearance accessible via mate-control-center command or menus. Using Appearance you can modify themes and Window Decorations, however there is much more that can be done or tuned missing in the MATE GUI using a couple of GNOME desktop environment native commands.

3. Change GTK Theme


Below commands are for GNOME 3 based desktop environments this includes also any other GNOME based Graphical Environments or components of GNOME 3 such as (Ubuntu Unity, GNOME 3 Shell/Classic, Cinnamon), and even the old GNOME 2 desktop.

In GNOME 2 it was possible to set various variables directly from gconf-editor including GTK Themes but in GNOME 3 somehow this is no more … so to do we need to use some cryptic commands or use gnome-tweak-tool or MyUnity (Ubuntu Linux users with Unity) but configuration that can be made with them is unfortunately partial so in any case knowing below commands is a necessity to be able to tune up nicely your Linux Gnome Desktop.

And yes it is crazy why on Earth gnome developers scaped out the configuration from gconf-editor and left us with this user unfriendly method. Could it be that someone (Like the big corporations) has the interest to ruin Free Software?? What do you think…
 

Unity, GNOME 3 Shell/Classic, Cinnamon

In Unity GNOME 3 Shell / Classic and Cinnamon (the default Debian graphical env).

Before we start I recommend you check out what is the current installed and enabled theme, you might want decide to keep it after checking the number of themes available. To check your current installed GNOME theme run:

 

gsettings get org.gnome.desktop.interface gtk-theme
'Adwaita'


You see I have 'Adwaita' theme as a default.
Next lets change the gnome GTK theme interface.
 

gsettings set org.gnome.desktop.interface gtk-theme "Menta"

 


MATE (In Linux Mate the current fork of GNOME 2 for hardcore GNOME 2 users)

 

mateconftool-2 –type=string –set /desktop/mate/interface/gtk_theme "Menta"

 


GNOME 2 (In native GNOME 2 if you still own some old machines with old Debian / Ubuntu / Fedoras etc.

 

 

gconftool-2 –type=string –set /desktop/gnome/interface/gtk_theme "Menta"

 


4. Change WINDOW THEME (Metacity)
 

Unity, GNOME 3 Classic (Metacity), GNOME 3 Shell (Metacity > Mutter)

 

gsettings set org.gnome.desktop.wm.preferences theme "Menta"


Cinnamon (Metacity -> Muffin)

 

gconftool –type=string –set /desktop/cinnamon/windows/theme "Menta"

 

Note: Cinnamon must be restarted for the change to take effect.


GNOME 2 (In Gnome 2 with Metacity)

 

gconftool-2 –type=string –set /apps/metacity/general/theme "Menta"

 


MATE (Metacity)

 

mateconftool-2 –type=string –set /apps/marco/general/theme "Menta"

 


Change SHELL THEME (In Gnome Shell and Cinnamon)


GNOME Shell (user-theme extension must be enabled)
 

gsettings set org.gnome.shell.extensions.user-theme name "Menta"


Cinnamon

 

gsettings set org.cinnamon.theme name "Menta"

 


5. Change GTK COLOR SCHEME

Unity, GNOME 3 Shell/Classic, Cinnamon (Change GNOME3 Color scheme)

 

 

gsettings set org.gnome.desktop.interface gtk-color-scheme "bg_color:#e9efe9;fg_color:#444444;base_color:#ffffff;text_color:#333333;selected_bg_color:#6666cc;selected_fg_color:#eeeeee;tooltip_bg_color:#222222;tooltip_fg_color:#dfcfcf;link_color:#cc0099;"

Reset color (if you don't like it):

gsettings set org.gnome.desktop.interface gtk-color-scheme ""

 

MATE (Mate set color scheme)

 

 

mateconftool-2 –type=string –set /desktop/mate/interface/gtk_color_scheme "bg_color:#e9efe9;fg_color:#444444;base_color:#ffffff;text_color:#333333;selected_bg_color:#6666cc;selected_fg_color:#eeeeee;tooltip_bg_color:#222222;tooltip_fg_color:#dfcfcf;link_color:#cc0099;"

 

 

Reset color :

 

mateconftool-2 –type=string –set /desktop/mate/interface/gtk_color_scheme ""

 


6. GNOME 2 (Again for the old GNome 2 machines to change the GTK Color scheme)

 

gconftool-2 –type=string –set /desktop/gnome/interface/gtk_color_scheme "bg_color:#e9efe9;fg_color:#444444;base_color:#ffffff;text_color:#333333;selected_bg_color:#6666cc;selected_fg_color:#eeeeee;tooltip_bg_color:#222222;tooltip_fg_color:#dfcfcf;link_color:#cc0099;"

 

Reset color:
 

 

gconftool-2 –type=string –set /desktop/gnome/interface/gtk_color_scheme ""

 


What about colors, well the #444444 and #22222 and #eeeeee, #333333 seen as color codes in above examples can easily decrypted if you don't know them using a tiny tool called gcolor2
The tool is installable on most Linux distributions with a simple apt-get install gcolor2 or yum install gcolor the tool is convenient and a must have for anyone using Linux for basic design or graphic operations with some program as GIMP / Krita / Inkscape / Vectr / Karbon etc.

All gcolor2 does is to make easy for you to get HTML color codes and convert existing ones into colors for you, here is shot:

https://ubuntuforums.org/showthread.php?t=1778355

While talking about setting color another interesting Graphical tool related to article, that gives you abilities to change colors in GNOME is gnome-color-choose, the tool is really awesome and allows you to do many of the color tunings shown in above examples

# apt-get install –yes gnome-color-chooser

And finally for the gnome theme hungry people, here is a great bonus. If you need a ton of shiny new themes as possibility to set up on your GNOME download and install The Ultimate Edition Themes deb (Debian / Ubuntu Mint) etc. collection (mirrored):

Debian and other deb based distro users can easily download and install with:
 

linux:~# dpkg -i ultimate-edition-themes-.0.0.7_all.deb

 


Other Linux users such as Fedora ones and Slackware users (if anyone on Slack uses Gnome since KDE is default by default there), use alien tool to install it or directly open the file with Midnight Commander (mc) and copy the files to the /usr/share/themes dir.

 

This article is possible thanks to Change Theme Using Command Line in GNOME (Linux) command line examples are taken from there.

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 .;)
