   Thank you for the quick response.

   The drm-intel-fixes branch seems to have done the trick. No more
flickering. I think we can call this one fixed.

[Intel-gfx] i915 problems with suspend to disk

2012-10-07 Thread Hugo Mills
   Hi,

   On 3.6, I've got a problem with my video driver after resuming from
suspend-to-disk: the lower part of the display flickers, rapidly but
irregularly (think of a neon sign in a bad film noir), flicking
between the correct display and... something else, it's hard to see
what.

   Shutting the lid of the machine (to trigger a suspend-to-ram) and
waking it up again fixes the flicker.

   In syslogs, I have nothing obvious on suspend, and this warning on
resume:

   Hardware is a Lenovo Thinkpad Edge13, lspci says:

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset 
Integrated Graphics Controller (rev 07)

aka

00:02.0 0300: 8086:2a42 (rev 07)

   Let me know if you need more information. I can probably manage a
bisect if necessary -- it's easily repeatable as a bug.

   Hugo.
