I don’t use sys-gui-gpu myself, and I will admit that there are quite a few bugs when using it. Still, if it works, then the possible parts of the code that could be to blame is much lower. If sys-gui-gpu in PV mode works, then the problem is almost certainly the userspace drivers (Mesa). If sys-gui-gpu in HVM mode works, but it fails in PV mode, then the problem is likely in the way i915 and Xen interact. > > If PV sys-gui-gpu with a dom0-provided kernel works, then the problem is > > almost certainly old dom0 userspace: either an old X server, old Mesa, > > or both.
