Comment 7 for bug 139990

I see the same behavior with ATI Mobility Radeon X300. package versions:

xserver-xorg 1:7.2-5ubuntu13
xserver-xorg-video-ati 1:6.7.195-1ubuntu2

Also, I used to work with two external monitors with my T43 laptop. After the latest upgrate, I am unable to get one of the monitors working together (even fails to work in mirror mode). some relevant info:

I want to have LVDS and VGA-0 working together. But I can only get LVDS and DVI-0 in mirror mode.
