I installed Ubuntu 12.10 and at first when I go to check the system information I used to have (unknown) on the graphic card section, I used the synaptic manager and downloaded the fglrx, after that I restarted my laptop and now I don't have any menus, all of them are gone.
Now I am only using the keyboard shortcuts to use Ubuntu. My graphic card is AMD ATI.
What can I do to bring the menus back?
After booting to recovery mode select the option 'remount' as suggested in the comment above.
Drop into a root shell with internet acces ('netroot' option) and try executing the following commands to reset your graphics driver configuration to the ubuntu default drivers.
sudo apt-get remove --purge xorg-driver-fglrx fglrx*
sudo apt-get remove --purge fglrx*
sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
sudo dpkg-reconfigure xserver-xorg
Restart your computer using
sudo reboot
And boot up normally
Or if you have installed the drivers manually from the binary download available on the amd website run these commands:
sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
sudo apt-get install --reinstall xserver-xorg-core libgl1-mesa-glx libgl1-mesa-dri
sudo dpkg-reconfigure xserver-xorg
sudo reboot
Try running fgl_glxgears. If the driver is correctly installed, you should see an animation of a cube looking like this:
If you get an error, that means the driver is either incorrectly installed, or not installed at all. In order to install it, follow these instructions.
Best Answer
Press Ctrl+shift+F1 and type this command after you logged in to the system
It will remove the drivers that you have just installed, they are not compatible with the new version of the X server and will break Unity when you install them.
There is a current open bug with it on Launchpad.net, please signing and follow it for further progress. This is an ATI drivers issue:
