Bug#801081: xserver-xorg-video-qxl: QXL video unusable due to performance

[Jason Briggs <royalsheeplauncher@zoho.com>]

WORKAROUND (finally!!!):

sudo editor /usr/share/X11/xorg.conf.d/50-qxl.conf
# insert the following:
Section "Device"
  Identifier "qxl"
  Driver "qxl"
  Option "ENABLE_SURFACES" "False"
EndSection
# save + reboot with QXL video

This was suggested on a mailing list for a downstream Jessie distro, thanks to those guys. The original reference: http://lists.freedesktop.org/archives/spice-devel/2012-November/011479.html

I don't know if this is a real solution (strange that xserver-xspice is missing) but with this fix Iceweasel and apps now seem to run at full speed in my Jessie VM.
