Blank Desktop, No Wallpaper and right click on Ubuntu 13.10

Got my first error after upgrade to Ubuntu 13.10 (from 13.04) two days ago.

After a quite long search in google without any luck, this is what I do :

1. Run dconf-editor (via Dash | dconf-editor, or Terminal | type dconf-editor)
2. Click org
3. Click gnome
4. Click desktop
5. Click background
6. Click primary color
7. Click Set to Default
8. Click secondary color
9. Click Set to Default
10. Done

You will get your desktop, wallpaper and mouse right click again after that ;)

Ubuntu performance tweak

This is what you can do to increase your Ubuntu access speed and performance

1. Set swappiness to the allowed lowest value, usually the default value is 60

rumy@cbug-nest:~$ cat /proc/sys/vm/swappiness
60

2. Edit /proc/sys/vm/swappiness and change 60 to 10 (assuming RAM > 1 GB)

sudo pico /proc/sys/vm/swappiness
{change 60 to 10, save with [Ctrl] [O] [Enter], exit with [Ctrl] [X]}
cat /proc/sys/vm/swappiness
10

3. Edit /etc/sysctl.conf, and add vm.swappiness=10, vm.vfs_cache_pressure=50 to the end of file

sudo pico /etc/sysctl.conf
{move cursor to the end of file and then add this}
vm.swappiness=10
vm.vfs_cache_pressure=50

{Save with [Ctrl] [O] [Enter], exit with [Ctrl] [X]}

4. Reboot

Unable to install Nokuntu

If you are unable to install Nokuntu on Ubuntu, and got this error message :

unable to open file ‘/var/lib/dpkg/tmp.ci//usr : Is a directory

Assuming that the working directory is where the nokuntu deb file reside, do the following :

mkdir nokuntu
cd nokuntu
ar x ../nokuntusp*.deb
mkdir control
cd control
tar xzvf ../control.tar.gz
rm -rf usr
tar czvf control.tar.gz *
mv control.tar.gz ..
cd ..rm -rf control
ar -r ../nokuntusp-new.deb debian-binary control.tar.gz data.tar.gz
sudo dpkg -i ../nokuntusp-new.deb

After that all you have to do is install all the gambas dependencies
