    Default fglrx 8.1 Dual Head, bad resolution :(

    Yesterday I got a new 22"W monitor to connect to my laptop and updated my kubuntu 7.10 to use the fglrx 8.1 driver.

    The resolution of my laptop screen is 1400x1050, and the new monitor is 1680x1050.

    I tried to configure a "big desktop" using the fglrx control panel, but it sets up both monitors as 1400x1050 (total of 2800x1050). I can not select "3080x1050". But, if I select "Analog Monitor (2)" from the fglrx control panel it says that maximum resolution is "1680x1050".

    My Xorg file:

    Do you know any way of making this work? All I want is a big desktop with native resolution. I do not need 3D acceleration. I do not mind changing to another version. I also tried the free driver but it doesnt make a big desktop at any resolution.

    Thanks

    Default Here's my xorg.conf

    I have the same card and I just connected a 22" monitor myself about a week ago. Here is my xorg.conf. Unlike you however I wanted 3D accel on my 22" so I disabled my laptop screen. Nevertheless, I think the ForcedMonitors option might point you in the direction you want to go. Also consult the fglrx man page for description of the options. There is some stuff commented out that didn't work the way I wanted, but it might be useful for you... I hope it works out

    I forgot to mention, I'm using xorg-server-1.4.0.90 and xorg-input-evdev-1.2 so my input sections might appear odd comparatively. I wouldn't recommend copying anything in there unless you are ready to play with HAL configs

    Code:
    Section "ServerLayout"

    #	InputDevice    "Keyboard0" "CoreKeyboard"
    	InputDevice    "cursor" "SendCoreEvents"
    	InputDevice    "stylus" "SendCoreEvents"
    	InputDevice    "eraser" "SendCoreEvents"
