Arch Linux

As of yesterday (May 7) i've been seeing blank screen after resume from suspend.
I suspect primarily KDE (move to 4.10.3) as I _can_ see the login screen after resume, fill in the password, and then KDE boots to blank screen where I see only a mouse cursor. I can switch to vt1 and do killall X as a workaround.

Nothing strange in the dmesg.
System was resuming fine ~2 days ago.

Later I can downgrade to [core] to check.
