Xorg.0.log

I have a Lenovo Thinkpad T440s with Intel graphics. I'm using a dual monitor
setup - the internal 1920x1080 display on eDP1 and a 1920x1200 screen (HP ZR24w
on DP4 via the docking station).

(Running Factory as of now, but tried 13.2b1 yesterday and had the same
effect.)

Leaving the system alone for a bit leads to the screens being turned off
(powersave). However, only the internal display wakes up again; the external
output remains in power-save mode.

(e.g., the monitor doesn't find any signal on any port.)

I tried using xrandr --output --off and turning it on with --auto again,
turning off the monitor itself, etc. No change; the only apparent way to
resolve this and get my external monitor back is to reboot, which seems a bit
harsh.

Any suggestions?
