My GUI doesn't RUN!!!

If you want the GNOME desktop environment (default for Ubuntu), run
sudo apt-get install ubuntu-desktop
For KDE, it's "kubuntu-desktop" and for Xfce, it's "xubuntu-desktop".
You should then be able to get to the GUI with
startx

Hello

Please try to press CTRL+ALT+"+" and/or CTRL+ALT+"-" to dynamically change video frequency
or press CTRL+ALT+BKSPACE to restart graphics layer.

Reconfiguring your xserver-xorg may help you.

A) If you can view graphics Gnome desktop

Please open a Terminal from the menu Applications->Accessories->Terminal
and jump to step C

B) If you cannot view graphics Gnome desktop

Please press CTRL+ALT+F2 and make login with your user and password
and go on to step C

C)

To make a backup copy of your actual /etc/X11/xorg.conf type:

cd /etc/X11
sudo cp xorg.conf xorg.conf.bak

give your user password when requested, you don't see nothing when you type it, then press enter.

Then try to reconfigure your xserver-xorg

sudo dpkg-reconfigure xserver-xorg

answer to the simple questions, then restart the pc.

If something goes wrong you can restore the saved copy of your old configuration, open a terminal or login to a virtual terminal by pressing ctrl+alt+F2 and type:

cd /etc/X11
sudo cp xorg.conf.bak xorg.conf

and restart the pc, type:

sudo reboot

If it doesnt work:

Course to a terminal (Press cntrl + alt +f1 or f2 in the login screen) Or boot up in recovery mode (Usually 2nd option in grub menu)

and give the following command:

sudo apt-get remove kubuntu-desktop

and

sudo apt-get install kubuntu-desktop

and reboot your system..

sudo reboot

Hope it helps
