Package: xserver-xorg
Version: 1:7.7+16
Severity: normal
Hardware: Lenovo X250 (Intel Graphics), with 2xDELL U2713HM connected
via docking station's Display Ports.
Since upgrading to the modesetting driver, the monitor I'm currently
focussed on often goes blank for a second, while I'm working. The others
are unaffected. I'm assuming that the display port connection is
resetting, because if I have a monitor menu up, when triggering the bug,
it gets closed, as the screen blanks. Nothing gets logged.
It seems to be usually caused by opening a terminal or pressing a key in
a terminal just after switching focus, but I can't explain any of that
:)
It seems to happen less often if I turn one of the 3 monitors off. And
I've never seen it happen on the internal eDP panel, only on the DP Dell
monitors.
Using the intel driver avoids the problem, but it seems to have picked
up other odd rendering bugs around the same time. Windows flicker
between previous and old contents.
Seen with Linux 4.6.0-1 and 4.7.0-rc7.
