folks,
X (Xorg-x11) fails under dom0 (unstable-tree) on my environment.
If it works for me, it''s very appreciated.

Most chipset specific drivers should work fine, and typically work better anyhow. Support VESA drivers doesn''t work for two reasons: 1) it tries to map pages in the bottom megabyte of machine memory, and 2) it needs to make call backs to the BIOS. #1 is trivially implemented, and it might make sense for dom0 to have access to the bottom megabyte of machine memory for other reasons (e.g. ACPI). I don''t know enough about the mechanism used for protected mode BIOS calls to know how best to implement them, but I suspect we''d have to bounce them via Xen. Anyhow, can you try a chipset specific driver?

This is just a completely random thought and not really related to this thread at all... the X protocol can use shared memory in the case where the display is on the same pc as the application. What would be involved in making shared memory work with X in the case where an application running in a dom != 0 is using a display (X server) on dom0?

Yes, it looks easy. It''s just been disabled in the Makefiles. However --- does your X server work without MTRR support?

Currently X gives only black-out screen, and log (Xorg.0.log) stops just after (II) I810(0): Primary V_BIOS segment is: 0xc000 (WW) System lacks support for changing MTRRs It''s getting more difficult to track it down, but let me try to capture what''s going on little bit more. Thanks very much for your help. Oh, could you kindly instruct how can I enable MTRR support to make it built-in?
