I just performed an upgrade for my brother’s computer who also has an 845 onboard chipset.
The video displays garbage, and X locks hard. It won’t take any keyboard input. I can’t even change numlock.
I’ve tried wiping xorg.conf and also using sax2. I’ve tried reinstalling X, the kernel and kdm. No luck.
I may have to format the computer and reinstall 11.0. I suspect there is an issue with the kernel and the intel driver.
