[Bug 638831] [NEW] Blank screen at startup, only mouse pointer is visible.

[Sergio Zanchetta]

Public bug reported:

Maverick Beta (15-09-2010 build) live cd.

1) Ubiquity appears.
2) I select Try Ubuntu
3) I get a black screen with only the mouse pointer visible.

Looking at the kernel log:

[drm:rs400_gart_adjust_size] *ERROR* Forcing to 32M GART size (because
of ASIC bug ?)

This is the same error reported in bug #562843
