I¹m new to Linux and Xen. Just wonder if you tried gfx_passthrough in cfg?
=== Text From
http://forums.linuxmint.com/viewtopic.php?f=42&t=112013===gfx_passthru=0 # Set to 1 may help with some Nvidia cards. Search the
Internet for AMD cards and recommendations, though AMD cards should work
with 0. Setting gfx_passthru=1 will pass through the graphics card as
primary (and
only) display adapter, without first booting the virtual
Cirrus Logic adapter. In most cases this requires a patched Xen
hypervisor, but in some cases it may work, depending on the graphics
adapter and perhaps the Windows version in use.

Jason
