Christopher, 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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1486036 Title: Faulty graphics behaviour when resuming from suspend with intel graphics drivers Status in linux package in Ubuntu: Incomplete 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. --- ApportVersion: 2.17.2-0ubuntu1.4 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: julienl 1792 F.... pulseaudio /dev/snd/controlC0: julienl 1792 F.... pulseaudio DistroRelease: Ubuntu 15.04 HibernationDevice: RESUME=UUID=2233869d-5832-469c-a447-f4da17530958 InstallationDate: Installed on 2015-06-21 (91 days ago) InstallationMedia: Xubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422.1) MachineType: Dell Inc.
