Suspend/resume is handled by the kernel, so am bumping this over to them for troubleshooting. However this looks to me like perhaps something screwy with the nouveau drm module not reinitializing the GPU. The kernel team can guide you through testing some alternate kernels and bisect down to the fix if there is one.
Fwiw, the collected logs don't reveal anything about the bug (corruption issues almost never show evidence in logs). So I'd recommend doing a bit more experimentation on the hardware to see e.g. how often the flaw can be reproduced, if activities other than suspend/resume can cause it, if any nouveau kernel driver options make it more or less likely to occur, etc. Beyond that, test newer and older kernels. ** Package changed: xorg (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1051020 Title: MacBookAir3,1 has pulsing pixelated vertical line down right side of screen after suspend/resume Status in “linux” package in Ubuntu: New Bug description: After suspend/resume my MacBookAir3,1 has pulsing pixelated vertical line down right side of screen: * http://www.youtube.com/watch?v=_ymoZ9uIQ4E Logs and additional info should be attached below with ubuntu-bug.
