Description quachtlc 2015-08-11 09:39:27 UTC 
On resuming from one of the 2015 ThinkPad models, there is terrible graphics corruption. Text gets garbled, the performance is poor, etc. There is a bug opened in Launchpad for this issue: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1452318 but thought I'd open one in the intel component here. 

There is a workaround that if you change graphics acceleration from SNA to UXA, everything works but comes with super slow graphics performance. Please let me know if there is any other information I can provide.

Sure, the reason why UXA is unaffected is that UXA doesn't use the GPU...
Comment 2 Chris Wilson 2015-08-11 10:37:18 UTC 
This is probably the execlists resume bug, if so the w/a is i915.enable_execlists=0.

I'll that workaround, thank you for the quick response
Comment 4 quachtlc 2015-08-11 11:17:58 UTC

Comment 5 quachtlc 2015-08-19 20:39:54 UTC 
I thought I replied to this last week, bummer, but sadly the workaround didn't work

Closing this bug since it is to old, please re-open it if is needed.
