Description Markos Chandras 2009-03-08 12:14:35 UTC
As described on http://bugs.gentoo.org:80/show_bug.cgi?id=261112, there is an X lock up when resuming   from suspend to {disk,ram} when using xf86-video-intel-2.6.X series.

I will try to attach a log in a bit

And a some information about my system

Kernel: 2.6.28-gentoo-r2
Xorg-server: 1.5.3
Xorg-X11: 7.4
mesa: 7.3
xf86-video-intel: 2.6.3

2.5.1 driver works fine so I guess this is a regression on 2.6.X series

Let me know if you need more information

I've been hitting this as well on my thinkpad.  After resume on my X3100, I get a locked xorg, with an unmovable cursor:

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

After googling a bit, it seems many people are hitting this with the new drivers:

I've experienced this on 2.6.27.x and 2.6.28.x
Comment 5 Markos Chandras 2009-03-31 02:30:34 UTC
This behavior is not reproducable with the following combination

1) xf86-video-intel-2.6.3
2) 2.6.29 kernel
3) Xorg-1.6
Comment 6 Zaf Spelskie 2009-04-19 21:37:32 UTC
I have the same problem with intel 885GM.

kernel 2.6.29
xorg-server 1.6.1
xf86-video-intel 2.3.2

After resume from suspend the LVDS (laptop monitor) is blank but the VGA has no problem.
Comment 7 Zaf Spelskie 2009-04-19 21:41:58 UTC
Sorry, I meant 855GM, not 885GM.

reg_dump after suspend

captured after resume from suspend, still in text console (cannot see the text because the screen is blank). captured with intel_reg_dumper.

Markos, sounds like this bug is fixed for you.

Zaf, can you re-open if you still see failures with a more recent 2D driver?  Also, please attach your X log etc. from the failure, see http://intellinuxgraphics.org/how_to_report_bug.html for info.
Comment 11 Zaf Spelskie 2009-05-18 08:29:13 UTC
Thanks. The bug doesn't appear with xf86-video-intel 2.7.0
