Bug 82231 – ATI radeon M7 causes unusable video if switching between X and vt after a suspend/resume

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Alessandro Sappia 2005-02-16 03:39:38 UTC]

I've noticed that after a suspend to ram or disk
I can't switch between X and vt
if I suspend on vt, on resume switching to X causes hags on video ( I still can
use ssh not connect thru net)
if I suspend on X, on resmue X works but if I switch on vt and then back to X
I've the same effect as above...

how to reproduce:
(in a VT)
echo -n mem>/sys/power/state
(wait)
resume 
switch to X
you get unusable video

Bryan, you might want to add this patch to x11-drm.

Where has this patch come from? Has it been submitted upstream?

[Comment 4 Alessandro Sappia 2005-03-16 06:48:45 UTC]

Well,
the real problem is that seemed to fix this issue, but now I get
sometimes usable X but sometimes I still got fb freeze when switching to X.
SO I don't know how this patch is really the final solution to radeon resume freezes...

Ok, when you have figured out a solution with the upstream developers please notify us on this bug.

[Comment 6 Daniel Drake (RETIRED) 2005-07-07 15:47:57 UTC]

Is this issue still present in newer kernels (e.g. 2.6.12)?

[Comment 7 Daniel Drake (RETIRED) 2005-07-31 07:25:12 UTC]

If you'd like me to keep monitoring the upstream bug for solutions, please try
and reproduce with the current development kernel (currently 2.6.13-rc4), report
findings here and on the upstream bug, and tag this bug with
"watch-linux-bugzilla" in the status whiteboard.
