Hi,
having some problems setting up dualhead with radeonhd.
ATI Radeon HD3850 PCI-E
24" LG Flatron 1920x1200 <-- main monitor
20" Samsung SM206BW <-- extended
Kernel 2.6.30rc4 from here
xserver-xorg-video-radeonhd 1.2.5+git from here
Kubuntu 9.04
xorg.conf
Output from xrandr
When I bootup both monitors have 1680x1050 resolution and monitors are in clone mode (both show same picture) but when I run the commands
dualhead works... What do I add to xorg.conf so I dont have to run commands everytime I login?
