I'm using a laptop that I sometimes dock. I then have the laptop screen turned off and use instead a much larger separate screen. The resolution gets messed up when I login Xmonad (I guess it retained the laptop's original resolution). I then runxrandr --output HDMI3 --mode 1920x1200 to change it to the larger screen's full resolution, and everything looks nice. But the xmobar doesn't stretch across the full width of the screen and the background desktop image is tiled to fill the whole screen... 

I guess what I'm asking is, how can I best set up .xsession and / or xmonad.hs (and .xmobarrc) to make this work?

Ultimately I'd like it to work when I dock my laptop but also when the laptop isn't docked...

Hi, Yakir.
It seems to be xmonad issue only, it uses screen resolution retrieved when X session started and did not update it dynamically. I wonder what xmonad module is responsible for that issue and how it could be fixed.
