    Hi again. I'm now running Karmic on the same T60 and have kind of similar problems as in Jaunty:

    • Radeon cannot activate DVI-0
    • Radeonhd works better compared to radeonhd in Jaunty but is still sometimes (once/twice in a day) freezing the PC with Compiz desktop effects.


    Here are links to my Xorg.0.log files from boot to effort to activate DVI with xrandr

    Radeonhd http://pastebin.com/m77ec206a

    Radeon http://pastebin.com/m6f39d21

    I tried to activate DVI with radeon with these commands.

    Code:
    xrandr --newmode 1680x1050 146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync
    xrandr --addmode DVI-0 1680x1050
    xrandr --output DVI-0 --mode 1680x1050
    With the first attempt the T60 panel goes off and on like it would try to do something on DVI but nothing happens in the Dell LCD side. With second and later retries there is no flash in the local panel.

    I have also problem with radeonhd with corrupted display after opening T60 panel lid or in resume after suspend (didn't try with radeon). That used to work in Jaunty.

    BR,

    Not really based on longer experience - I had to remove options EXA and DRI to have acceptable stability with radeonhd. With EXA removal I lost video playback. Totem is crashing and gxine shows black screen

    I'm using the latest xorg edgers build of the radeon driver with kms enabled in karmic alpha.
    That sound interesting. What repository are you using?

    Did you have similar problems as I do have with default Karmic drivers?

    Best Regards,

    I went further to test with radeon driver from https://launchpad.net/~xorg-edgers/+...e/drivers-only. I have now the PPA added to software sources and the system updated.

    Without KMS the DVI-0 is not recognized. With temporarily added boot option to grub radeon.modeset=1 I get the same 1024x768 picture to both panel and DVI-0! Xrandr reports this:

    Code:
    Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
    VGA-0 disconnected (normal left inverted right x axis y axis)
    LVDS connected 1024x768+0+0 (normal left inverted right x axis y axis) 287mm x 215mm
       1400x1050      60.0 +   50.0  
       1024x768       60.0* 
       800x600        60.3  
       640x480        60.0  
       0x0             0.0  
    DVI-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
       1360x768       59.8  
       1152x864       60.0  
       1024x768       60.0* 
       800x600        60.3  
       640x480        59.9
    The problem is now that every attempt to change video mode results to somehow horizontally out-of-sync mostly white video looking crap, e.g.

    Code:
    xrandr --output DVI-0 --mode 1360x768
    The same happens with native 1680x1050 for LCD that I'd like to use. For some reason it's not in the retrieved EDID modes list. Fortunately I'm able to get now thanks to KMS a sane console with alt-F1 so I can shut down X properly.

    Here's again the log http://pastebin.com/m415cd9d0

    Is there something else I need to update to get radeon and DVI work properly? Kernel (now 2.6.31-11-generic)?

    Your DVI monitor apparently does not have an edid or has a problematic one which is why none of the drivers can get proper modes for it.

    It's a Dell 22" 16:10 monitor, about three years old. I'll try to get a dump done somehow perhaps with another PC and/or try to hook another monitor to the T60 next monday when I'm back at work. It's always possible that things break.
