When dmabuf_capable is enabled, ms_present_check_unflip may return
with reason PRESENT_FLIP_REASON_BUFFER_FORMAT to be reported back
to client by PresentCompleteModeSuboptimalCopy. We should not
overwrite it by page flip reasons anyway when exit.
This fix also avoid changing vblank->exec_msc in present_scmd_pixmap()
which caused by page flip reasons to prevent a present to be executed
immediatly. So that we can cancel pending vblanks when new vblanks with
same msc arrive. This happens when application just starts.
This problem can be observed at least using radeonsi OGL driver, start
xserver with dmabuf_capable enabled, no window manager, glxgears will
stuck for the first several seconds. If using a composite window manager
like Mutter, we can't observe the glxgears stuck, but the prensent
complete event still shows unexpected Copy mode instead of
PresentCompleteModeSuboptimalCopy or Skip mode.
glxgears window msc is 0 at the beginning, it will send present request
with target msc = 1, 2, 3, ... N before server send back the complete
event for target msc = 1. But server side window msc is way bigger than N,
so it will think all these present requests are outdated and just show the
Nth request at the next vblank. [1 .. N-1] requests should be skipped.
But without this fix, all [1 .. N] presents will be executed with Copy
mode which causes stuck.

XLibre Xserver
Xlibre is a fork of the Xorg Xserver with lots of code cleanups and enhanced functionality.
This fork was necessary since toxic elements within Xorg projects, moles from BigTech, are boycotting any substantial work on Xorg, in order to destroy the project, to eliminate competition of their own products. Classic "embrace, extend, extinguish" tactics.
Right after journalists first began covering the planned fork Xlibre, on June 6th 2025, Redhat employees started a purge on the Xlibre founder's GitLab account on freedesktop.org: deleted the git repo, tickets, merge requests, etc, and so fired the shot that the whole world heard.
This is an independent project, not at all affiliated with BigTech or any of their subsidiaries or tax evasion tools, nor any political activists groups, state actors, etc. It's explicitly free of any "DEI" or similar discriminatory policies. Anybody who's treating others nicely is welcomed.
It doesn't matter which country you're coming from, your political views, your race, your sex, your age, your food menu, whether you wear boots or heels, whether you're furry or fairy, Conan or McKay, comic character, a small furry creature from Alpha Centauri, or just a boring average person. Anybody who's interested in bringing X forward is welcome.
Together we'll make X great again!
Upgrade notice
-
Module ABIs have changed - drivers MUST be recompiled against this Xserver version, otherwise the Xserver can crash or fail to start up correctly.
-
If your console is locked up (no input possible, not even VT switch), then most likely the input driver couldn't be loaded due to a version mismatch. When unsure, it's best to be prepared to ssh into your machine from another one or set a timer that's calling
chvt 1after certain time, so you don't need a cold reboot. Or, make sure that you have magicSysRqkey enabled (Alt+PrtSc) via sysctl (kernel.sysrq=1), then press following combination depending on keyboard layout to make kernel regain control over keyboard to make VT switching work:- QWERTY/AZERTY keyboard layout:
SysRq + R - Dvorak/Colemak keyboard layout:
SysRq + P
- QWERTY/AZERTY keyboard layout:
-
Proprietary Nvidia drivers might break: they still haven't managed to do even simple cleanups to catch up with Xorg master for about a year. All attempts to get into direct mail contact have failed. We're trying to work around this, but cannot give any guarantees. But you can make it work by adding
Option "IgnoreABI" "1"line toServerFlagssection in Xorg config. -
Most Xorg drivers should run as-is (once recompiled!), with some exceptions. See
.gitlab-ci.ymlfor the versions/branches built along with Xlibre.
