[Ubuntu-x-swat] [Bug 1437807] Re: Suspend/resume fails with SNA acceleration on some WMs

Somehow the bug doesn't seem to affect kernel 4.0 (rc6) I just installed that and now suspend/resume works like a charm. Looks like it's a combination of components that causes this erratic behaviour. -- You received this bug notification because you are a member of Ubuntu-X, which is

Same on my XPS-13 9343 with i7-5500U and identical graphics card. I tried xorg-edgers, but no improvement (xorg-video-intel is version 2.99.917 there), it shows the same behaviour. Workaround with UXA is possible, but performance is abysmal, so no real solution. -- You received this bug
