external DVI monitor is black after wakeup from s2ram, until I press Alt+F1 and Alt+F7
This is a ThinkPad T440s with a stable 64bit hardened Gentoo.
If it is docked then the described behaviour happens.
I do run latest kernel, former kernel versions show the same behaviour.
All other functionality of the resumed system is fine, so it is just the monitor which needs an extra kick.
Any hints ?
