[Bug 726892] [NEW] screen split in half when in unity and I plug in a external monitor

 

Public bug reported:

Binary package hint: xorg

HP Pavilion dm4t-1100
I5 460M CPU
Intel + ATI 5470HD

When running under Unity and I plugin a second monitor the screen is
split in half horizontally. The top part shows parts of windows, the
bottom shows normal picture but what should be on the top. If using
Gnome, everything is fine.

I have xrandr script like this:
#!/bin/sh
xrandr --output LVDS1 --off --output VGA1 --mode 1680x1050 --pos 0x0 --rotate normal

This works perfectly in Gnome, but in Unity it switches to 1027x768
