Installed ATI drivers, now computer restarts at login screen.

Installed the latest x64 ATI drivers, now whenever I get through the boot process into the login screen my machine restarts...

Any ideas? I'm getting terrible video playback with the Radeon drivers.

add nomodeset and it should at least boot to the desktop. Then it will use Vesa drivers which is far worse than Radeon drivers.

What is your graphiccard? Maybe it's too ancient for AMD/ATI proprietary drivers? A card older than about 4 years is not supported by new Catalyst versions.

Oh just noticed that this is in the Fedora 16 forum. Fedoras 16 kernel and its xorg-version is not compatible with proprietary AMD/ATI driver. If you need proprietary AMD/ATI, you better use Fedora 15.

No, it's an HD5xxx card, supported by the drivers released 28/09.

Guess I'll have to wait for the new kernel and xorg to get ATI support, but having laggy video playback is definitely annoying in the mean time.

I might just delete xorg.conf and remove the ATI drivers outright...

what exactly is wrong with the video playback?

AdamW, I'm experiencing similar problems with an ATI Radeon HD 5450 on Fedora 16. It is true that the drivers are incompatible with the kernel and xorg in F16 beta. The Radeon driver however, at least gets the resolution right and the display working, but it is unusable due to bad flickering whenever the screen gets an update ( a window is moved, or a line of output is printed in a visible terminal window).

I didn't try fedora 15 though, I am currently considering getting rid of the GPU, since the onboard graphics (intel sandybridge) seem to be working much better and faster than the ATI GPU.
