Bug Description
On the IBM T20 laptop using the Savage drivers, when gdm starts X, the screen stays black with a "_". The sound is initialized (I can hear the startup sound) and I can login through SSH. The screen gets initalized every 3 to 4 times of startup but I can't decern a pattern. This has always worked in previous versions of Ubuntu.
Workaround: Add this to the Device section of xorg.conf:
Option "BusType" "PCI"
According to http://
The problem of lockups or video corruption as a result of 3D rendering is [not] well-known/
Option "BusType" "PCI"
Option "DmaMode" "None"

I'm not sure what X.org.logs I should attach, let me know and I can generate some log files.
