Ubunto xen cannot display video mode

[zarniwoop]

I am running Ubuntu Feasty 2.6.20-16 without any problem.

I have installed a 2.6.19-4 xen package. When I boot that I get the message "Cannot display this video mode, change computer display input to 1280x1024@60Hz"

Does anyone know why the xen-kernel cannot work with my X-settings which are standard for the monitor I use? And more importantly: how can I make it work?

I have tried various approaches at getting something xen-ish booted, all with the same result.

My system runs at 1280x1024@76Hz which is how Ubuntu recognised to run X for my monitor (Philips 190C). When I boot the 2.6.20 kernel, the 76Hz is fixed for all resolutions.....

You could try to modify /etc/X11/xorg.conf to make this work with your Xen kernel. Maybe try another resolution (I'm not sure if the frequency can be adjusted in xorg.conf).
