Description Allin Cottrell 2010-03-05 13:53:10 UTC 
Kernel 2.6.33; Xorg 1.7.5; drm, mesa and xf86-video-ati 
from current git; non-KMS mode. All this on a ThinkPad
T400, R600 video.

X starts fine and gives good 3D performance, but on
exit the console is blank. There's a shell there OK
and the machine responds to commands typed blind.
Ctrl-Alt-FN to console from a running X session also
gives a black screen.

I'm booting to a console using vesafb. I tried disabling
that (VGA console) and rebooting, but it didn't help,
still no visible console after X.

Seems to be a regression, since the same setup was
working fine with mesa 7.6 and earlier variants of drm
and xf86-video-ati from git; however that was also
before updating from kernel 2.6.32.8 so the 
experiment is not well controlled.

Please attach your xorg log and dmesg.

The Xorg log and dmesg are actually from kernel 2.6.32.9.
I booted using that to see if the results were better, but
in fact they were just the same. I can generate and attach
files from 2.6.33 if that may be useful.
Comment 5 Allin Cottrell 2010-03-17 10:35:01 UTC 
Just confirming that the problem (blank console after
exiting X) is still present with Linux kernel 2.6.33.1
and drm, mesa and xf86-video-ati updated to git as of
2010-03-17. I will attach current Xorg log and dmesg.

This shouldn't be an issue with kms.
Comment 9 Allin Cottrell 2010-10-20 06:16:18 UTC 
You're right, it's OK with kms.
