Re: [Xen-users] Help! Xen dom0 kernel-2.6.38 shows blank screen!

[Claudiu Curcă <alexstrasza2@xxxxxxxxx>]

Hello,

It does happen with recent kernels, though noone explained why yet.

A workaround is to either compile and load framebuffer modules for
your card, or install X. Once either of these is activated, you'll be
able to "see" again.

Good luck!
