One more clue: in kern.log, when xserver is running under hypervisor, this appears:
Nov 21 22:05:13 blueeyes kernel: [ 45.899070] Xorg:2949 map pfn expected mapping type writ e-back for d0000000-e0000000, got write-combining Nov 21 22:05:13 blueeyes kernel: [ 46.067758] Xorg:2949 freeing invalid memtype d0000000-e 0000000 And when the same binary xserver is running under the same linux kernel but not under hypervisor, it does not appear. bjb -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
