My fault, that's not part of upstream. Use sudo make modules_install

xorg intel crashing when screensaver starts
https://bugs.launchpad.net/bugs/595182
You received this bug notification because you are a member of Ubuntu-X,
which is subscribed to
just ask reporters to upload the original i915_error_state, then
it is much easier to reparse with latter versions of intel_error_decode.
(And doesn't then have a dependency on having intel-gpu-tools installed
on the reporter's machine at the time of the crash.)

[arrandale] VGA port not working on Dell Latitude E6510

some information
on the buffers allocated by the kernel. If X is the only rendering
client, the number of buffers should be very close to the number of
pixmaps, or there is a bo refleak.
One suspects the leak lies with Eclipse... Or hopes. ;-)

I think the core issue here is that there is no mechanism by which the
user can easily know the state of the capslock. I think the following
solutions would rectify this:
- Notify the user via an Application Indicator that the capslock has either
been enabled of disabled.
- Have an icon appear

The problem here is that the shortcut appears to be acted upon when the
keys are pressed, rather than released, which is a known bug (bug
#36812).

Hi Chris,
I just tested the standalone OpenGL compositor fbcompose
from this site
https://launchpad.net/~fluxbox-maintainers/+archive/nightly/+packages
fluxbox-fbcompose_1.3.2+nightly+120311-1_amd64.deb
... on a i5-3550, Debian wheezy,
(In reply to comment #105)
I still can see tearing even if driver option TearFree is enabled, when I
rotate display right or left (xorg monitor Option Rotate), so when the
axes are reversed.
Yup, that's expected at this moment in time. To avoid tearing down will
require another indirection
Hmm, the X.log indicates 2.17, there were a few related fixes as well,
can you please install a 2.20.8 from your distrobution updates?

Hmm, there is some similarity here between this and bug 51616 if in both
cases the kernel reports the pipe as active, but in reality it is
disabled.

Given the batch submit immediately after the vsync'ed copy, I can't see
what else userspace can do to prevent the WAIT_FOR_EVENT hang...

Closing as the UXA DPMS off vs pageflip race.
