The GL freezes still occur when using Ubuntu kernel 4.5.3. I wanted to
try newer kernels (those tagged with yakkety), but the 14.04 LTS
wouldn't boot to desktop with them.

Oh, that's gonna take a while until I find the right time to do this
kind of experiment.

Martin Pecka, to see if this is already resolved, could you please test
http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

Hmm, I feel it is probable that the i915 error and OpenGL freezes are
two separate issues. I tested with various kernels, and these are the
results:
GL bug:
3.13 KO
3.19 KO
4.2 KO
4.3 KO
4.4 KO
4.5 KO
i915 bug:
4.2 KO
4.3 OK
4.4 OK
So it seems 4.3 kernel has fixed the i915 issue, but the GL

This is a followup of
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1501260 .
Basically, running OpenGL applications (e.g. glxgears) on the primary
display handled by Intel 915 card results in display
So far I've tried with older kernels installed on my system. I'll try
with newer kernels later. And I incorrectly reported my Ubuntu version -
it's 14.04.4 now, and I think the error did not appear on 14.04.3.
3.13 and 3.19: the GL window freezes as described, but the i915 error is
not printed in
Martin Pecka, thank you for taking the time to report this bug and helping to
make Ubuntu better. Please execute the following command only once, as it will
automatically gather debugging information, in a terminal:
