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.

hi;
I'm extremely new to linux - and may be way off base concerning a Mac,
but if once KDE is up, perhaps you can Open a Konsole (or K-menu | Run
) and type in;

kxconfig

please correct me if I'm mistaken, as I have an older PPC 7300/200 (OS
9.0.1) and I've hardly ever used Macs before -- I'm lurking to try and
decide whether or not to try load a YD distro onto it (or the correct
variant)

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. :-(
