Strange things on Randeon X800 (DVI-0 / DVI-1) using AVLinux 5

touchstyle · 07-11-2011, 03:35 PM

I'm using AVLinux, with 2.6.39.2.avl.3 kernel.
I have some problem about dual screen (xinerama).
My graphics card is this:

Code:

04:00.0 VGA compatible controller: ATI Technologies Inc R430 [Radeon X800 XL] (PCIe)
04:00.1 Display controller: ATI Technologies Inc R430 [Radeon X800 XL] (PCIe) (Secondary)

Using "arandr" (... thanks!) I can't place DVI-0 on the left or on the right of DVI-1: it seems that both output DVI-0 and DVI-1 are connected to the same signal, and I can only use two monitor with the same image.
Using "lxrandr" it is the same: with the second output disabled, both monitors switched off.
I tried to use "sgfxi", but it does not complete the installation, it comes out after finding the card correctly.
Output of xrandr:

Code:

Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 1280 x 1280
DVI-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm
   1280x1024      60.0*+   75.0  
   1280x960       60.0  
   1152x864       75.0  
   1024x768       75.0     70.1     60.0  
   832x624        74.6  
   800x600        72.2     75.0     60.3     56.2  
   640x480        75.0     72.8     66.7     59.9  
   720x400        70.1  
DVI-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 338mm x 270mm
   1280x1024      60.0 +   75.0* 
   1024x768       75.0     70.1     60.0  
   832x624        74.6  
   800x600        72.2     75.0     60.3     56.2  
   640x480        75.0     72.8     66.7     59.9  
   720x400        70.1

It seems there is a problem of identification of DVI-0.
The two monitors are "seen" as being related to DVI-1.

Thanks, Touch.

Updating.
The same issue with Avlinux 5.0.2, based on Debian Squeeze 6.0.3.

Any suggestions?

Thanks,
Touch.
