Hi all,
I've got a BB xM with Ubuntu 10.10 installed. Worked fine so far,
until I tried installing the SGX acceleration, following
http://elinux.org/BeagleBoardUbuntu#SGX_Video_Acceleration
I followed all the steps and it seemed to go fine. But now on reboot
all I get for gdm is a black screen.

If I try to restart pvr, I do get the Stopping/Starting PVR, but it
doesn't fix the issue, and I see this in the dmesg:
