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.

Cleaning Packard Bell Hera GL laptop running Windows XP from Viruses and Spyware (Viruses / Spyware which can make CD drive and Wireless seem unworking)

Packard Bell Hera GL Fixing Broken RaLink Wireless

Yesterday, one (girl)friend of mine brought me one Packard Bell notebook, which had a 2 years old Windows installed on it.
As one can imagine Windows XP on it is full of Spyware and Viruses. Besides the software problems the notebook had some hardware problems with the CD / DVD which is not reading CD / DVDs at all.

Initially I thought, the CD unable to read problems are caused by the infected Windows, however even restarting the PC with a bootable Hirens BootCD and a Whoppix liveCD and trying to boot from it failed this convinced me its a CD / DVD combo drive hardware failure.

By the way, I’ve just recently found out about Nixory – Is a nice Free Software Open Source AntiSpyware tool for Firefox, IE and Chrome.

I hope it will get a sharp development and soon, when some friend asks me to fix his stupid non free-Windows PC, I would not have to use a trial version of Malware Bytes but directly use only Nixory

Anyways after using Nixory, MalwareBytes and Avira and thoroughfully scanned the system in Safe Mode and found and deleted some 15 Spyware / Viruses and tampered a bit with the Wireless Driver settings all the notebook devices started working fine again.

The wireless had also one really odd problem on this Packard BellHera GL, even though the notebook wireless antenna was capable of detecting all the wireless networks it couldn’t properly connect to any of it but failed to get proper IP addresses.
Partially the unable to grab an IP via wireless router dhcp server got fixed by using the Wireless restart Button (located on the Notebook corpus).
However even after cleaning up the Virus and Spyware the Wireless Networks connectivity problems on this Packard Bell continued, until I changed also few settings in the Control PanelI never thought Viruses / Spyware infected can have some bad impact on Wireless Card and CD drive make them unsusable though they showed like working correctly in Windows Control Panel -> System ??

In the meantime I reinstalled the Wireless Driver for the notebook, the Wireless card on the notebook was showing up itself under the name of Ralink 802.11n Wireless Lan Card in Windows Device Manager

After re-installing the wireless driver I had to also change few settings for the Wireless Network Connection using the menus Properties -> Configure -> Extended; therein everywhere for each Value I make it be Enable and for Power Saving Mode , I’ve choose the Value option of CAM

After a system reboot, everything started working finally fine. One last thing to add is that before I fixed the Ralink wireless to work under Windows, I tried to use a Bootable Linux LiveCD but even there the wireless was failing to connect to the wireless networks (maybe this shit wireless device has some issues with its Linux drivers).

How ot fix Widgets drag and drop not working on WordPress

how to fix WordPress widgets missing drag and drop bug

My WordPress blog had an odd problem, all on the blog, worked just fine except the Widgets add new widget drag and drop functionality.
As there was new version of wordpress available I tried updating but this fixed the missing drag and drop widget functionality neither, so finally after a bit of googling and experimentation to follow suggested fixes like using the enable Accessiblity Mode button on top Widgets.Thus the common suggested fix that worked for most of the people who stumbled upon this annoying wordpress bug was to simply nagivate to:

Appearance -> Widgets -> Screen Options -> Enable Accessibility Mode As for me pressing over the Screen Options was impossible (nothing happened when I pressed over it), finally I’ve found a hack 😉

The hack is quite simple, all I had to do is just pass a variable ?widgets-access=on to the widget.php php script
Therefore the fix to the problem was as follows http://blog.mysite.com/wp-admin/widgets.php?widgets-access=on

And done, FIXED! 😉

How to change / reset lost or forgot TightVNC administrator password

how-to-change-reset-lost-TightVNC-administrator-password

I have installed TightVNC to a Windows host just a few weeks ago in order to be able to manage remotely a Windows host and forgot to write down the administrator password 🙂 (stoopid!)

I had to explain to a friend remotely how to change the TightVNC admin password and it was a complete nightmare!

Shortly here is the exact menus one who wants to reset the password of a TigthVNC server after forgotten:

Start -> All Programs -> TightVNC
-> TightVNC Server (Service Mode) ->
TightVNC Service - Offline Configuration.

In the configuration dialog to popup there are the Server and Administration tabs through which a new password can be set.

After the password is change either a restart of the TightVNC server is necessery or a restart of the Windows PC.

How to install Toshiba Satellite L40 B14 Wireless Adapter ( ID 0bda:8197 Realtek Semiconductor Corp. RTL8187B) on Ubuntu and Debian Linux

How to install Toshiba L40 B14 Wireless Adapter ( ID 0bda:8197 Realtek Semiconductor Corp. RTL8187B) on Ubuntu and Debian Linux
I've been struggling for more than 10 hours to fix up issues on a Ubuntu Maverick-Meerkaat with a rtl8187B Wireless Adapter

The RTL8187B almost drove me mad. I could see the wlan0 which meant the kernel is detecting the device, I could even bring it up with ifconfig wlan0 up , however when I tried it in gnome's network-manager or wicd the wireless networks were not showing up.

Trying to scan for networks using the commands:


ubuntu:~# iwlist wlan0 scan

was also unsuccesful, trying to bring up and down the wireless wlan0 interface with:


ubuntu:~# iwconfig wlan0 up

or


ubuntu:~# iwconfig wlan0 down

Both returned the error:
iwconfig: unknown command "up" and iwconfig: unknown command "down"

Running simply iwconfig was properly returning information about my Wireless Interface wlan0 :


wlan0 IEEE 802.11bg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off

The exact information I could get about the wireless device was via the command:


ubuntu:~# lsusb | grep realtek
Bus 001 Device 002: ID 0bda:8197 Realtek Semiconductor Corp. RTL8187B Wireless Adapter

Trying manually to scan for wireless networks from console or gnome-terminal with command returned also the below weird results:


ubuntu:~# iwconfig wlan0 scan
iwconfig: unknown command "scan"

More oddly tunning wlan0 interface with commands like:


ubuntu:~# iwconfig wlan0 mode managed
ubuntu:~# iwconfig wlan0 essid ESSID
ubuntu:~# iwconfig wlan0 rate 11M

were succesful …

I read a bunch of documentation online concerning the wireless card troubles on Ubuntu, Gentoo, Debian etc.

Just few of all the resources I've read and tried are:

http://rtl-wifi.sourceforge.net/wiki/Main_Page (Returning empty page already a lot resource)
http://rtl8187b.sourceforge.net (A fork of rtl-wifi.sourceforge.net which is still available though it was not usable)

Some of the other resources which most of the people recommended as a way to properly install the RTL8187B wireless driver on linux was located on the website:

http://datanorth.net/~cuervo/rtl8187b/ (Trying to access this page returned a 404 error e.g. this page is no-longer usable)

I found even a webpage in Ubuntu Help which claimed to explain how to properly install and configure the RTL8187B wireless driver on which is below:

https://help.ubuntu.com/community/WifiDocs/Device/RealtekRTL8187b

Even the Ubuntu help instructions were pointing me to the broken cuervo's website URL

Anyways I was able to find the rtl8187b-modified-dist.tar.gz online and made a mirror of rtl8187b-modified-dist.tar.gz which you can download here

Another rtl8187b driver I found was on a toshiba website made especailly for the wireless linux drivers:

http://linux.toshiba-dme.co.jp/linux/eng/pc/sat_PSPD0_report.htm

The questionable file which was claimed to properly be able to make the Realtek Semiconductor Corp. RTL8187B Wireless Adapter to work out was called rl8187b-modified-804.tar.gz.
I've made a mirror of rtl8187b-modified-804.tar.gz is here

None of the driver archives rtl8187b-modified-dist.tar.gz and rl8187b-modified-804.tar.gz that was supposed to make the Toshiba L40 realtek wireless to work out, after compiling and installing the drivers from source worked out …

Both archives produced plenty of error messages and it seems on newer kernels like the one on this notebook:

Linux zlatina 2.6.35-28-generic #50-Ubuntu SMP Fri Mar 18 19:00:26 UTC 2011 i686 GNU/Linux, they're no longer usable.

The compile errors I got when I tried compiling the rtl8187b driver provided by the archive rtl8187b-modified-dist were:


root@ubuntu:/home/zlatina/rtl8187b-modified# sh makedrv
rm -fr *.mod.c *.mod *.o .*.cmd *.mod.* *.ko *.o *~

root@ubuntu:/home/zlatina/rtl8187b-modified#

Another driver I tried which was found on aircrack-ng.org's website was rtl8187_linux_26.1010.zip

Here are the error messages I experienced while I tried to compile the realtek wireless driver from the archive rtl8187_linux_26.1010.0622.2006


compilation terminated.
make[2]: *** [/home/zlatina/rtl8187_linux_26.1010.0622.2006/beta-8187/r8187_core.o] Error 1

make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-28-generic'
make: *** [modules] Error 2
make: *** [modules] Error 2

I tried a number of fix ups hoping to solve the compile error messages, but my efforts were useless, as it seems many things has changed in newer Ubuntu versions and they could no longer be compiled.

As I realized I couldn't make the native drivers provided by the above sources compile, I decided to give a try to the Windows drivers for Realtek 8187B with ndiswrapper, a link for download of Realtek 8187B (RTL8187B_XP_6.1163.0331.2010_Win7_62.1182.0331.2010_UI_1.00.0179 is found here

I untarred the
RTL8187B_XP driver
and used ndiswrapper to load driver like so:


root@ubuntu:~# tar -zxvf
RTL8187B_XP_6.1163.0331.2010_Win7_....L.tar.gz
root@ubuntu:/home/zlatina/RTL8187B#
root@ubuntu:/home/zlatina/RTL8187B# cd Driver/WinXP
root@ubuntu:/home/zlatina/RTL8187B/Driver/WinXP# ndiswrapper -i net8187b.inf

In order to test the RTL8178B Windows driver I used:


root@ubuntu:~# ndiswrapper -l
net8187b : driver installed
device (0BDA:8197) present (alternate driver: rtl8187)

To finally load the Windows XP RTL8187B driver on the Ubuntu I used again ndiswrapper:


root@ubuntu:~# ndiswrapper -m

Further on I used the ndisgtk graphical ndiswrapper interface to once again test if the Windows driver is working on the Ubuntu and it seemed like it is working, however still my wicd was unable to find any wireless network ….

There were many online documentation which claimed that the driver for rtl8187b works out of the box on newer kernel releases (kernel versions > 2.6.24)

Finally I found out there is a driver which is a default one with the Ubuntu e.g. rtl8187.ko , I proceeded and loaded the module:


root@ubuntu:~# modprobe rtl8187

I also decided to check out if the hardware switch button of the Toshiba Satellite L40 notebook is not switched off and guess what ?! The Wireless ON/OFF button was switched OFF!!! OMG …

I switched on the button and wicd immediately started showing up the wireless networks …

To make the rtl8187 module load on Ubuntu boot up, I had to issue the command:


root@ubuntu:~# echo 'rtl8187' >> /etc/modules

Voila after all this struggle the wireless card is working now, it's sad I had to loose about 10 hours of time until I come with the simple solution of using the default provided ubuntu driver rtl8187 , what is strange is how comes that it does not load up automatically.

Thanks God it works now.

Still Here

Wednesday, January 17th, 2007

Aloha. Still here. Two days ago I ran Heroes 3 under my FreeBSD box successfully, there was a terrible bug in fullscreen mode which needed fix I’ve used the loki’s site patch to patch the heroes 3 start binary with xdelta. The loki installer was a terrible pain in the ass I used my l337test sk!llZ :} to be able to patch the binary by hand. About the last post yes I was desperate still not good still living. Today I was on exam again a failure probably, nothing new.

As I often used to say in the fast if something starts bad then it overs bad too. See my life show this very well. I’m suffering terrible and still waiting for something to set me free to happen. What would be the turning point? Will there be turning point at all? No idea. If God is such good and powerful as he said in the bible and his promises are true then he will deliver me and set me free on a good ground. Still hoping … Prodigy — Speedway, else the earth is probably his favourite experiment.
