Xen users - Nov 2006 - Blank Screen on Boot

Hi,

When I boot a Xen kernel either from Debian Etch or FC6 the screen goes 
blank shortly after loading the kernel.  The system otherwise boots as 
normal.  Under FC6 X (xorg) then loads and the screen comes back but 
this hasn''t happened with Etch.

I''m not using the onboard graphics card, instead an dual head matrox
PCIe.

I''ve tried setting vga=normal in GRUB.

Thanks,

Andrew

Right now I''m guessing it is a module compiled in that isn''t
in either
of the stock kernels?

Turns out this problem isn''t exclusive to Xen kernels as someone on one
of the Ubuntu lists has a similar problem.  Even though I can''t get a 
display under text mode, X will work.

To try, in no order, are:

* rm /etc/X11/xorg.conf - and let X autoconfigure
* vi /etc/X11/xorg.conf - and use a lower resolution, 800x600, until you 
fix the xorg.conf
* just edit xorg.conf and read the X logs to debug xorg.conf as normal.

So in short it is working by just configuring X properly - still can''t 
text mode working ...
