Description Bryan O'Sullivan 2006-01-24 15:44:17 EST
Description of problem:

I have an IBM Thinkpad X31.  I just installed FC5T2 by doing an upgrade from
FC4, and now X busyloops after I close and reopen the lid.  This did not affect
me with any prior Fedora release.

The X server cannot be killed with kill -9.

Version-Release number of selected component (if applicable):

The modular xorg stuff in fc5t2 seems to be at fault here.

How reproducible:


Steps to Reproduce:
1. Start X.
2. Close laptop lid.
3. Reopen.
Actual results:

X consumes 100% of CPU and cannot be killed.

Expected results:

Normal behaviour :-)

Additional info:

I have the following graphics chip:

I'm lowering the priority on this, as ACPI support is stable enough that I can
now suspend and resume in ACPI.

Thanks for the report.  Please attach your X server log file and config file
from the problematic scenario, as individual uncompressed file attachments
using the link below.

Problems of this nature may require direct physical access to the hardware
in order to diagnose, and so it is a good idea to report the issue directly
to X.Org bugzilla as well, to maximize the number of developers seeing the
issue.  I'm not sure if we have this hardware available to directly diagnose
the issue internally.

Once you've filed a bug report with X.Org bugzilla, please paste the URL
here and we'll track to the X.Org bug report as well.

Thanks in advance.

I'm sorry, Mike, but I just spent a few hours configuring ACPI "just so" so that
I can use suspend to RAM and to disk, and also modified my X configuration in
various ways.

Since I now have a stable machine again, I don't think it's worth spending both
of our time tracking down this APM-specific problem.  It might be best to
recommand that Thinkpad users who use APM should now switch to ACPI.

Thanks for the quick response.
Comment 4 Mike A. Harris 2006-01-24 18:24:23 EST
Ok, no problem.  I think we have recommended ACPI over APM for a few years
now in general anyway, although I'm not sure if that's ever been in release
notes or whatnot.

I'll keep this in mind if further bug reports come in though, and suggest
people try ACPI instead as well.  X11R7 actually has some initial ACPI
support built into it as well now, so it may turn out to be the best
solution anyway.

Thanks again!
