Hi all,
Since installing 13.04 I do not seem to be able to use my external monitors properly. The first monitor (connected by vga cable) seems to work but only up to 1600x1200 while it was up to 1920x1200 before. While my other monitor (Yamakasi 27" connected via the display port) does not even show signs of starting up (the power led normally flashes red for a min before coming on).
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1600 x 1200, maximum 1600 x 1200

This is only showing the monitor connected on the analogue port :-

If I try and set the modes by hand :-

Anyone else have this problem before? It was fine on 12.10... Any help would be appreciated!
