It's in the compiz source at tests/system/untest/ and is built with the
source but never packaged. Just build lp:compiz and then run:
cmake_build_dir/tests/system/untest/untest
Ah, that's handy.
Fwiw, just building lp:compiz did not compile the test, but I was able
to manually make it
I don't doubt there are some X crashes hiding here amongst this
functionality, however I am not able to reproduce any crashes on my
hardware.
Possibly the changes for kernel/X/etc. that have gone in since this was
originally reported have fixed whatever was crashing, or perhaps there
is something
OK but I fear for if we declare precise fixed and enable unredirection
for intel in Mesa 8. With the large number of Ubuntu users, even a crash
that effects 1% will cause a large headache and lots of bug reports. On
the plus side, that would result in a good number of stack traces, one
would hope
I'm not able to reproduce the crash using compiz-core 1:0.9.7.12-0ubuntu1.
I cleared Unredirect Driver Blacklist and verified Unredirect Fullscreen
Windows is checked, and reproduced the test case a number of times, but never
got a crash.

Bryce,
I wrote a stress tester that will successfully crash the intel driver on
precise (at least within minutes). It's in the compiz source at
tests/system/untest/ and is built with the source but never packaged. Just
build lp:compiz and then run:
I should point out that in writing untest I discovered the crash only
happens when you're running fullscreen OpenGL apps. Fullscreen regular
windows won't trigger it.

I didn't spot anything in the libdrm changelog relevant to this. There's
a few buffer flushing changes in the newer ddx driver, but they appeared
related to corruption issues rather than crashes.
I'd built compiz from source and installed it, but on restart unity
didn't come up. Does compiz need
Yes I think you would have to install compiz to /usr. However to avoid
clobbering your system I'd recommend:
cmake .. -DCMAKE_INSTALL_PREFIX=~/staging
and then:
cd staging
env DISPLAY=:0 LD_LIBRARY_PATH=./lib XDG_DATA_DIRS=./share:$XDG_DATA_DIRS
COMPIZ_CONFIG_PROFILE=ubuntu
Confirmed quantal is still free of this and other intel crashes I had in
precise.

Bryce, All,
I think I also failed to mention that you need to be using Compiz
0.9.8.4 or later, even on precise. So maybe use trunk (lp:compiz).
The features to make unredirect mode toggle reliably have not yet been
backported to compiz 0.9.7 for precise.

I've re-tested with your updated test case, but still works fine for me.
I'll need to have you re-test.

Testing this on precise on gm45 (i965), I do not reproduce this bug
using the test case outlined in the description.
From comment #4 it sounds like you are not reproducing it in quantal.
Can you check whether your system still reproduces it on current
precise?
** Changed in:
Actually Bryce; there's an implicit setup step (very important)
missing from the above test case, which applies to all tests in
Unredirect.txt:
CCSM Composite Unredirect Fullscreen Windows = ON
Please try that.
