Bug#801081: Re: Bug#801081: Re: xserver-xorg-video-qxl: QXL video unusable due to performance
Thank you! I had same issue on other distro I do not use anymore (mageia) so upstream is better, but it looked like it was never going to happen (they do not appear in his git yet or I miss it).

Bug#801081: Re: xserver-xorg-video-qxl: QXL video unusable due to performance
Please include this patch as well:
http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-qxl.git/plain/qxl-kms-disable-composite.patch
it appear to help with glitches.
Is there any chance these two patch can make it into Jessie? The reason is
because it affects all jessie live CD and live CD can't be used properly at all
with KVM/spice, it really break functionality and there is no workaround there
unless you rebuild the CD. There is still 2 years of life to jessie and all
downstream suffer.

Bug#801081: xserver-xorg-video-qxl: QXL video unusable due to performance
Dear Maintainer:
I need to advise you that the current package in Stretch xserver-xorg-video-qxl
0.1.4-3+b1 is
***NOT*** fixed
on my Stretch I manually recompile xserver-xorg-video-qxl and applied the
following patch:
http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-qxl.git/plain/no-surfaces-kms.patch
using this patch on the recompile package, the issue no longer happens (when
kms enabled).
To be specific, with this patch enabled, even though Xorg.0.log report that
surfaces enabled,
they behave as if disable and all works. This is the same behavior I can see
when I ran a Fedora;
log say enabled but no issue, because in fact disable internally.
I advise please apply the patch above to package (if there is no other patch in
works).
This can't be in the next Debian.
In addition I advise to check other patches listed:
http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-qxl.git/tree/
to see if they fix anything else, such as qxl-kms-disable-composite.patch
I can confirm there is other issues with QXL driver (other than this bug) with
4.x+ kernel such as broken auto-resizing ("Auto Resize VM with Window" broken).
Thank you

I need to add some information. Here is a link to a thread to Jessie downstream distro suffering from issue: https://forums.whonix.org/t/qxl-slowness-fix/1759 Fedora has some patches applied to QXL and maybe they would help: http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-qxl.git/tree/ http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-qxl.git/tree/no-surfaces-kms.patch <- this one is interesting!!! http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-qxl.git/tree/qxl-kms-disable-composite.patch <- maybe of value http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-qxl.git/tree/0001-worst-hack-of-all-time-to-qxl-driver.patch <- if all else fails
Bug#801081: Re: xserver-xorg-video-qxl: QXL video unusable due to performance
Hello, I tried some time ago to install the qxl driver from testing into Jessie but it hang with green screen on boot. I tried a few days ago to make a new vm of Stretch and it still has the problem. To make qxl usable I have to disable the offscreen surfaces as in the conf. It speeds up everything to near perfect. For example the main page of wikipedia can't be browsed in iceweasel, it's too slow. There was also more artifacts in the Stretch vm. Seem fixed by disabling offscreen surfaces. I add that .conf to all my VMs manually now.

Bug#801081: xserver-xorg-video-qxl: QXL video unusable due to performance
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.
Bug#801081: xserver-xorg-video-qxl: QXL video unusable due to performance
I wonder if these issues and lack of configurability aren't related to the fact that xserver-xspice package (part of QXL source) appears to be missing from Jessie altogether?? https://packages.debian.org/stretch/xserver-xspice Another note: I've found this affects other Jessie-based distros as well. ps: sorry for line length
Bug#801081: xserver-xorg-video-qxl: QXL video unusable due to performance
Another way to replicate: Simply run the Jessie live CD (debian-live-8.2.0-amd64-xfce-desktop.iso) as a guest in Virt-Manager with QXL driver (default) and try to load Iceweasel and try to scroll through some websites for 10 minutes. Even with spice-vdagent missing, with only the qxl driver the browser is so slow and glitchy it's virtually unusable on my host systems. Then kill machine and switch to VGA driver, reload VM and try Iceweasel again. VGA appears slower in XFCE at first but then Iceweasel runs great and speed is constant in general. Again there is no spice-vdagent in the live CD so obviously the qxl driver is the problem.
Bug#801081: xserver-xorg-video-qxl: QXL video unusable due to performance
Minor correction: I used the Cirrus driver on Wheezy machines. For Jessie machines I have it set to the VGA driver (because Cirrus has issues on Jessie guests as well). I had no luck trying to backport the xserver-xorg-video-qxl package from Sid locally on my own (green screen) and limited ability to look further.
