I have Ubuntu 8.10 64bit and a x1800XL. I just installed the 8.12 dirvers and I have two problems:
1. I cannot autologin. With the one's provided from the Ubuntu repo I could
2. If the tv-out cable is connected then X fails to start. I can't even restart it(ctrl-alt-backspace). This also failed with the one's from Ubuntu repositories.
I pretty much know that the second bug won't be fixed until a new driver version is released.
I'd like to know if there is a fix for the first problem!
