Description Jiri Brunclik 2006-05-17 04:46:06 UTC

I'm trying to set up dualhead on my notebook with i915. Resolution of the LFP 
is 1280x768, resolution of my external LCD is 1680x1050.

With the latest snapshot of i810 driver (from 
http://dri.freedesktop.org/snapshots) the dualhead works only with resolution 
1280x1024 or lower and only when I disable DDC (when DDC is enabled, LCD's 
refresh rate is set to 75Hz).

When I set higher resolution than 1280x1024, the LCD runs at 1280x1024@56Hz 
and reports incorrect video mode.

Log/config files can be found here: http://www.brunclik.net/tmp/i810.txt

Best regards,
-Jiri Brunclik
