Fwd: 3.18.3->4 : external monitor is black after wakeup of a docked system after s2ram

[Toralf Förster]

In the mean while I have to correct it - it is reliable.
So something between 3.18.3 and 3.18.4 break a docking system configuration in that manenr, that after resume the external (iand internal X11 screen) is black.

Happened 2 times here (but not always) that a docked Lenovo T440s (intel graphic) doesn't show anything at the external display (KDE 4.13.3). System is a hardened stable 64 bit Gentoo Linux

Nothing suspicious in the log however.

Known issue ?
