Hi,
I've just started to play with a new Acer Aspire S5 test box and noticed that garbage is displayed after resume from suspend to RAM with the 3.10 kernel (under KDE 4.10.3 on openSUSE 12.3). The display corruption goes away after killing X and restarting it.
The CPU is a Core i5-3317U (Ivy Bridge), i915 graphics.
That doesn't happen with 3.9 (same config otherwise). It also doesn't happen with my older Sandy Bridge-based box (with 3.10), so I suspect Ivy Bridge specifics.
Is this known? Do you want me to bisect?
Screenshot of the garbage would be a good start I'd say.
Well, it's just garbage. Attached anyway.
When the "screen lock" password prompt screen starts it's completely garbled. When I blind-type in the password, the desktop shows up and it looks kind of OK until a new window is opened and then it looks like rectangular area full of horizontal lines.
Also, does a vt-switch not resolve the issue?
No, switching VTs back and forth doesn't help when this happens (it makes things worse actually).
It's not 100% reproducible (but close to that on the IVB machine) and I've seen it once on my other machine based on Sandy Bridge too.
Thanks, Rafael
