The fix for CVE-2026-93519 moved the updates of pbd->last_timestamp and pbd->barrier_event_id from after they were used to generate the data in events to before, causing the event_id to be one too high, and the time delta (ms - pbd->last_timestamp) to always be zero. This fix moves them back to being after they are used to generate the event data. Fixes: |

Switching to XLibre
The easiest way to install and run XLibre is to use your distribution's provided packages. Please see the Are We XLibre Yet? - (X11Libre/xserver Wiki) page for a list of the available options. If there is no option, then go on with building and installing XLibre from source.
Building XLibre
After cloning the Xserver repository or unpacking the sources and installing the dependencies, change into the source directory and run the Meson build tool:
cd "<source dir of xserver>"
meson setup <prefix> build <meson_options>
ninja -C build install
You may specify the install <prefix> with, for example, --prefix="$(pwd)/image" and add build time <meson_options> like so: -Dxnest=false. You may also want to build and install some graphics and input drivers. Please refer to the Building XLibre (X11Libre/xserver Wiki) page for more details.
Configuring XLibre
Until XLibre releases its own, you can find a detailed description of the configuration on the Configuration - Xorg (ArchWiki) page. If you have built and installed XLibre yourself, then change into the <prefix> directory with cd <prefix> and create a directory etc/X11 with a file xorg.conf and adjust it accordingly.
Starting with version 25.0.0.16, the proprietary Nvidia driver is autodetected and handled internally without any special configuration. Please see the Compatibility of XLibre (X11Libre/xserver Wiki) page for more details on the Nvidia driver and compatibility in general.
Running XLibre
If you installed XLibre using your distribution's provided packages, then the Xserver is usually started by init (Wikipedia) on system start. On other systems it should be possible to manually start XLibre with user permissions by invoking startx. Please refer to man startx for how to use it.
If you have built and installed XLibre yourself, then you may want to shutdown other Xservers, change into the <prefix> directory, and create a simple testx.sh file with the following contents:
#!/bin/sh
./bin/X :1 vt8 -logfile /dev/stdout &
_pid=$!
sleep 10 && kill $_pid
You can adjust the :1 vt8 and other options in the testx.sh file as detailed in man Xorg. Make the testx.sh executable and run it:
chmod 0770 testx.sh
./testx.sh
This should give you 10 glorious seconds of a black and beautiful and empty screen. Afterwards the Xserver complains about being killed, but there should be no other critical errors for a "test passed." For more details, please see Building XLibre (X11Libre/xserver Wiki).
I want to help!
That's great; there's enough to do for everyone. You may consider one of the many ideas and feature requests out there. To help in testing, you may consider becoming an XLibre Test Driver. Please also have a look at the good first and help wanted issues and the Liberated Screens.
If you want to work on anything, just let us know. If you have any questions, just ask. Thank you!
