Quick'n'dirty: boot an Ubuntu livecd, copy somewhere the
/etc/X11/xorg.conf and then set it in your YDL installation

A bit more elaborate: try to discover the horizontal and vertical
frequencies of your monitor and setup manually your xorg.conf.



... which is quite easy.
In the Open-Firmware tree, you will find a file with the display EDID
blocs dumped.
find /proc/device-tree -name EDID will give you the file.
Then use a program to dump it (there a program named read-edid somewhere...)
and use the timings from the display prefered mode.
If you don't succeed, mail me the EDID file I'll post the result here.



Thanks for all the suggestions. Before trying any of them I tried the 4.0.91 beta and this seems to do the trick. It also fixes a number of other problems, most notably with fan control on the G5 Xserve.

The only down-side now is that I can't install Y-HPC on top of the newer YDL kernel. :-(
