[Bug 1486036] Re: Faulty graphics behaviour when resuming from suspend with intel graphics drivers


    Thanks, I have begun the bisection on the kernel version level. I have one question about it.
One of the versions I tried did not work at all (graphics didn't display). Should I label and keep moving on from there or try adjacent versions to this one until I find one where the graphics displays again?

Here is the result so far, I will now go from the precompiled kernels to the source level (might take me some time, I'll try one tonight do the rest another time):
4.3.0-040300rc2-generic good
    v4.1-rc2-vivid good
            v4.0.2-wily good
                v4.0-rc5-vivid good
                    v4.1-rc2-vivid good
                        v4.0-rc1-vivid inconclusive (no graphics show up)
        v3.19.8-vivid bad
3.19.0-25-generic  bad

Note that  v4.1-rc2-vivid good, v4.0-rc1-vivid and v3.19.8-vivid bad are
all adjacent to one another. Will now bisect between v4.1-rc2-vivid good
and v4.0-rc1-vivid.

  Faulty graphics behaviour when resuming from suspend with intel
  graphics drivers

Status in linux package in Ubuntu:

Bug description:
  Waking from suspend, everything seems normal, except the graphical
  elements and text on my desktop are not drawn properly. Sometimes,
  moving the mouse over icons can cause them to be redrawn, sometimes
  not. It appears not to matter how I initiate the suspend (e.g. by
  closing laptop lid, or by calling pm-suspend explicitly) and it
  appears not to matter whether I am using an external display or the
  laptop's own screen. All other hardware appears to be working, and I
  can restart the laptop by clicking where the icons ought to be. The
  only symptom seems to be that the drawing does not happen correctly.
