Note that this bug and the two dupes have different ways of reproducing
the bug, but all three are running Sawfish.
** Summary changed:
- Natty Xorg crashes on Thinkpad X201 (i915 driver) when using keyboard-based
window management
+ Xorg crash in PlayReleasedEvents with Sawfish when using
The (Ubuntu patched) code in question is:
static void
PlayReleasedEvents(void)
{
QdEventPtr prev, qe = syncEvents.pending;
DeviceIntPtr dev;
DeviceIntPtr pDev;
prev = NULL;
while (qe)
{
if (!qe-device-deviceGrab.sync.frozen) == line 1188

FWIW, after upgrading to oneiric, this segfault still occurs. However,
if I use xorg packages from debian/testing, the problem disappears. (am
using xserver-xorg 1:7.6+9, xserver-xorg-core 2:1.11.1.902-1, xserver-
xorg-input-evdev 1:2.6.0-2+b2, which are slightly newer than what
oneiric has but
I'm digging into this today. So far, I can say that #1 didn't change
any behavior that I could see (same crash occurs), and #2 disabled my
input devices entirely. So I'll continue down the list and let you know
what happens.
(BTW, in #2, the synaptics input packages don't seem to have built;
Using the debug packages you provided in #3, I get a different
traceback. It's consistent across crashes, except for a few values.

Hi Selene,
I've studied this a bit more and come up with a plan.
1. I notice in your Dependencies.txt that it lists you as having -evdev
u12 installed, but there is an -evdev u12.1 available with a fix to a
bug not dissimilar to this one (LP #774978). The backtrace in that case
is different,
I've been trying to avoid this, but as long as I had a crash today, I
decided to get more data. I can consistently reproduce the crash by
starting X, starting 5 urxvt windows, then rapidly moving windows around
with H-arrow keys. It takes maybe 15 seconds to trigger the bug in most
cases.
But

hi there,
same probleme here, same backtrace.
It does it since i upgraded to natty.
it does it with both nvidia and nouveau drivers.
when i was using natty my workaround was to downgrade X and nvidia to
maverick's versions.
I've now upgraded to oneiric, so i'm stuck.
btw, i'm also a sawfish
btw, i'm also a sawfish user, and i happen when i launch a new rxvt with
a keyboard binding (super-w here)

Title:
Natty Xorg crashes
Hi, this bug drives me crazy as well. Although I am running fedora 15
but not ubuntu (with a similar kernel though 2.6.38.7-30.fc15.x86_64).
It crashes randomly just as Selene discribes. I am working on a Thinkpad
X201s with dual monitor setup.
Attached is the Xorg log file.
I hope someone could
** Description changed:
Binary package hint: xorg
Ever since upgrading to natty a couple days ago, I've been having
problems with Xorg crashing. I got a traceback (already attached,
gdmlog1), which suggested something related to pthreads, so I tried
disabling hyperthreading and all
