[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):
v4.0-rc1-vivid inconclusive (no graphics show up)
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

Faulty graphics behaviour when resuming from suspend with intel
Status in linux package in Ubuntu:
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.
