[Ubuntu-x-swat] [Bug 475429] Re: [i945] X Freezes when compiz enabled

2011-06-01 Thread Bryce Harrington
This appears to have been fixed by kernel drm commit
b0b544cd37c060e261afb2cf486296983fcb56da, posted in January.  The fix is
probably already available in natty's kernel, but will leave it to the
kernel team to verify.

Thank you, takashi. I have reopened the upstream bug report and copied
your comment and dmesg there.  There will probably be more questions in
the upstream bug report. Please answer those there directly.

2010-07-15 Thread Geir Ove Myhr
Tomas, the question in comment #59 was meant for the original reporter
of the bug, takashi torigoe (sorry for not specifying that).  These kind
of bugs may look exactly the same but have totally different underlying
causes, so your freeze may be an unrelated bug.

If you are the experiencing freezes in Maverick, please file a new bug
report about it. In the bug reporting process Launchpad is pretty eager
to lead you towards possible duplicates. While that makes sense for most
packages, you can ignore that for graphics-related bugs. We (and the
upstream developers) would rather have many duplicate bug reports than
people contributing their information to a bug reports which turns out
to be different from their bug.

There is some automatic freeze-detection set up in Maverick, which may
tell you about the problem and offer to send a bug report. If that does
not happen, please file a new bug report with the ubuntu-bug command,
which will gather a lot of useful information for you.

I see you have a new Launchpad account. Welcome! I hope you can
contribute to making Ubuntu better.

It still freezes with Maverick (13th July), same as Tomas.

$cat /sys/kernel/debug/dri/0/i915_error_state
no error state collected

dmesg is attatched here.
dmesg shows that the freeze is caused by mutex lock.

It may be caused by below sequence.
1. mutex locked and not unlocked.
2. DRM_IOCTL_I915_GEM_PREAD wait the lock.
3. dmesg shows error ( 120s after freeze ).

According to the upstream bug report, two commits to the kernel should
fix this bug. The commits are included in the current Maverick kernel.
Could you verify that this now works in Maverick?

According to a comment on the upstream bug report, this bug is probably
fixed in intel's Q2 release (http://intellinuxgraphics.org/2010Q2.html).
Maverick doesn't have libdrm 2.4.21 yet, but should otherwise be up to
date.  Also, Lucid with xorg-edgers and a new mainline build of the
kernel (https://wiki.ubuntu.com/KernelTeam/MainlineBuilds) should
contain all the updates.

I rebuild the kernel with debug enabled.
And I tried to investigate the freeze problem.
But, kernel configuration(attached with this post) works fine.
I couldn't reproduce the problem with the kernel.
There might be some problems with lock sequence of the intel driver.

configuration change:
cpu arch - atom ( still freeze with this change )
debug feature show in below is enabled.

Hallo,
I have a similar problem. I'm running a fully updated (up to 17-apr-2010) 
9.10 on a Toshiba A100 with a intel 945 chipset. When desktop effects are 
enabled (extra), the screen, mouse, keyboard and power button are freezed when 
a full HD monitor is connected to the vga port and I try to run it at 
1920x1080. The laptop lcd screen is at 1280x800.
The freeze doesn't happen if the external screen is run at 1024x768.
If the desktop effects are disabled, no freeze occurs even when the external 
monitor is at 1920x1080.

I can run the laptop with full desktop effects with no problem at all
for days when only the laptop lcd is used and no external monitor is
connected.

Also, sometimes I can enable the external monitor at 1920x1080 both with
and without the laptop lcd enabled at the same time, with full desktop
effetcs enabled. The success rate is higher if power up the laptop with
the external monitor already connected and turned on.
