I'm an absolute beginner with ubuntu. After installing 11.10 I get a message to install ATI proprietary driver. The new one can't be installed, the older one get installed. After installation I must reboot. I do so and my monitor shows me something like "70Hrz horizontal and 60Hrz vertical are not supported" on a black screen. I don't find a way to set other resolution like 1024x768 or 1280x1024 and I can't see something, even CPU seems to be working.

I think it's related to the monitor not the card. –  hbdgaf Apr 4 '12 at 19:59

From the above forums post, boot to recovery mode and run the following commands

apt-get remove --purge xorg-driver-fglrx fglrx-kernel-source
apt-get update
dpkg-reconfigure xserver-xorg

Reboot and X should work.

You can try to install the proprietary drivers, check to see if your card is supported first
