You can also add in: https://bugs.launchpad.net/bugs/364960 (submitted
by me).

My Compaq Presario B1900 (most Linux-unfriendly laptop ever made...)
uses the ATI chipset. Completely removing (purging) all packages with
"xorg" or "xserver" in their name, then re-installing "ubuntu-desktop"
seems to have fixed things up (under Jaunty).

No idea why the server was (apparently) running happily, but not
displaying anything but a mess and not responding to any input events...
Worked fine under Hardy and Intrepid.

Anyway, fixed now. All I need to do now is get the wireless going again
and then, one day, have another look at the crazy RealTek audio chip...
