RE: [Xen-devel] X11_EnterFullScreen fails
If this is the case, though, why does only full-screen mode fail? Why
not the normal non-full-screen mode?

Highly likely. Unfortunately we cannot salvage any data during crash.
But I think this is a great pointer, especially since I am also facing
problems trying to get TinyX to start in the graphics mode - but the
vesafb driver tries to access the BIOS and it fails for exactly the same
reason (it is in protected mode by that time). The result is, however,
not a crash but a flimsy looking "text mode" like screen.
Thanks

What's the crash symptoms? Is it possible that the X11 driver is calling
the BIOS, and that this fails in Xen due to restrictions on running
real-mode, which doesn't happen in native mode?
