Description Will Woods 2006-03-08 17:10:03 UTC

FC5t3 suspends and resumes fine on my Thinkpad T43, once I add
'acpi_sleep=s3_bios' to the kernel command line.

After installing pm-utils-0.11, X locks up on wakeup from suspend and makes the
display completely unusable. The system is still functional - I can blind-type
commands or ssh in. Switching VTs and/or restarting X has no effect. 

This problem manifests regardless of kernel version. Turning off drm does not
affect it. Removing the 'acpi_sleep' item from the kernel commandline does not
fix it. Upgrading to pm-utils-0.13 does not fix the problem, but reverting to
pm-utils-0.09-1.2 does. 

The error in Xorg.0.log is:

Removing the vbetool lines from suspend_video() and resume_video() (in
/etc/pm/functions-intel) fixes my problem.

When the X does crash, I can switch to VT1 and do 'telinit 3; telinit 5' to
attempt to bring X back. It starts up enough that I see the mouse pointer for a
moment, and then crashes again.

I have a i915 in my HP Pavillion dv1240us.  When I resume, my display used to
just remain dark.  Now, however, I am getting an almost working display.  The
rendering for Metacity, Firefox, Gnome Terminal and other apps are all messed up.  

Here's what I sent to the Fedora Users mailing list:

I am running Rawhide + all updates (probably very close to FC5T3).
After resuming after suspend, Metacity, Firefox, Gnome-Terminal, etc
all have completely messed up rendering.  For example, when I scroll
in Firefox, only about the bottom .5" of the display moves.  Nothing else
changes.When I scroll back up, the top .5" changes.  Also, in composing
this message using gmail's web UI, there is no cursor displayed.
When I bring Gnome Terminal to the foreground, the nothing but the
Metacity frame is refreshed.  The square cursor appears, blinking.

If I click on the Gnome Terminal window frame and drag it, the
terminal's Metacity frame disappears.  Killing programs and restarting
them does not help.  It is a real mess.  Has anyone else seen this?
I will look in the bug database for an existing bug report.

I tried acpi_sleep=s3_bios and it made no difference for me.  Still get all the
problems on resume.

Comment 4 Will Woods 2007-04-11 17:36:05 UTC

This works for me in current rawhide, with or without acpi_sleep=s3_bios.
