Hi everyone!
I have two monitors connected with DVI and VGA, and my computer has DQ87PG motherboard and Intel HD Graphics 4600. I have a problem of extending the screen between these two monitors, but all that happens is one monitor is automatically a mirror of the other. I am currently using suse 12.3 and KDE desktop platform. One of the suggestions from previous similar kind of posts was to use the xrandr to set them up, but this is what i get as i type it on the console:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 77.0*

Can anyone please help me on this.
