      Description

      Created an attachment (id=5821)
      last pages of kernel debug log

      On real hardware.
      Booting liveCD, and have chosen in options "VGA mode".

      It runs long and eventually failed.
      There is no way (yet) to get entire log, but I used my (uncommitted yet) kmsg command to look at it, so I see attached last few pages of log, it's manually reentered.
      ***

      Seems error started here:
      (subsystems\win32\win32k\ntuser\display.c:175) VGA mode requested
      (subsystems\win32\win32k\ntuser\display.c:85) InitDisplayDriver(\Device\Video0, \Registry\Machine\System\CurrentControlSet\Services\VGA\Device0);
      (subsystems\win32\win32k\eng\device.c:74) Could not open driver \Device\Video0, 0xc0000034
      (subsystems\win32\win32k\ntuser\display.c:219) failed to query the registry path: 0xc0000034
      (subsystems\win32\win32k\ntuser\display.c:246) No usable display driver was found.

      and further Winlogon could not register as service.

      What is the problem here? Why it can't load \Device\Video0 ?
      What can be done here?
