Bug #11500
Poor graphics performance in KVM guest with QXL driver
100%
Description
A few of us have experienced that, along with some “out of surface” log spamming, for years. This has been reported to Debian and some workarounds are listed there:
- disable surfaces with a patch from Fedora (and while we’re at it, http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-qxl.git/tree/qxl-kms-disable-composite.patch apparently “helps with glitches”)
- disable surfaces via config file
Debian maintainers understandably want the patches to go upstream first, which apparently is planned, but we might want to be faster, e.g. with the config file option.

This does fix the performance issue for me, and also Bug #11489 :)

Yay, after testing it manually I must say I like the improved performance a lot! I haven’t run the automated test suite, which uses QXL, myself, but Jenkins did, successfully: https://jenkins.tails.boum.org/job/test_Tails_ISO_bugfix-11500-slow-qxl/2/
Merged!
Also: perhaps some reliability issues we’ve seen in the automated test suite, like the focus not moving to a text field fast enough after clicking it, will be solved too? Would be a nice bonus!

Let’s try to reintroduce this in Tails 2.5, but only write /etc/X11/xorg.conf.d/qxl.conf
if we can detect that such hardware is available through some service running before X.

Yes, that’s exactly my plan :)

Done on the topic branch, works fine in a VM with QXL. Will test on bare metal later.

Works fine on bare metal as well, please review’n’merge :)
