No display after installing ATI Catalyst™ 9.3 Proprietary Linux x86 Display Driver

Did you run the aticonfig to update your xorg.conf file?

Yeah I ran aticonfig. After driver installation display seemed to be fine. But after reboot I can see only KUBUNTU booting, after that its just blank screen. My biggest problem is i'm not able to work in the system and I have very important data. Do I have to reinstall Ubuntu? and is it possible to retain all the data even after reinstall? Please help

Backup your /etc/X11/xorg.conf file and run this:
sudo dpkg-reconfigure -phigh xserver-xorg

This should get you back to normal. Then you can work on configuring
the ati stuff later.

Hi Micah,

      As there is absolutely no display (not even command mode), i'm not able to see or type anything. Once I boot my system everything is just blank. I'm struggling to get display back. I would be happier if I get the command mode also. Please help me in getting the min command mode display. Do I have to reinstall Ubuntu? and is it possible to retain all the data even after reinstall? Please help so that i can type something.

Thanking in advance

Boot into rescue mode (press esc to get the menu). It'll boot up in text mode and bring a menu. In that menu try the fix X configuration option and try to resume boot from there. If X still doesn't work, do the rescue mode again, go for root prompt and remove the fglrx packages:
apt-get remove fglrx-modaliases fglrx-kernel-source xorg-driver-fglrx fglrx-amdcccle

Then restore /etc/X11/xorg.conf to one that doesn't speak of fglrx (probably an empty one there; otherwise you can also do the X configuration fix in the menu), reboot and everything should be fine. I had the same issue with ATI drivers (Mobility Radeon X1300), but the open source drivers work fine.
