Regardes mon lien ça pourrait t'aider car tu utilise le driver Intel :
Si en plus tu as
Kernel driver in use: i915
Kernel modules: i915
Alors c'est ça le problème
https://forum.ubuntu-fr.org/viewtopic.php?id=2061044
Il faut passer en mode modesetting car les derniers kernel intègrent les drivers pour intel pour gérer le graphisme directement dans la carte mère sans avoir de carte video externe PCI par exemple.
Supprimé xserver-xorg-video-intel et xserver-xorg-video-nouveau
et on obtient DRI3
xdpyinfo | grep DRI
DRI2
DRI3
pour info :
Il faut tester :
inxi -G

Package: xserver-xorg-video-intel (2:2.99.917+git20200714-1 and others)
X.Org X server -- Intel i8xx, i9xx display driver
This package provides the driver for the Intel i8xx and i9xx family of chipsets, including i810, i815, i830, i845, i855, i865, i915, i945 and i965 series chips.
This package also provides XvMC (XVideo Motion Compensation) drivers for i810/i815 and i9xx and newer chipsets.
This package is built from the X.org xf86-video-intel driver module.
The use of this driver is discouraged if your hw is new enough (ca. 2007 and newer). You can try uninstalling this driver and let the server use its builtin modesetting driver instead.

Install the mesa package, which provides the DRI driver for 3D acceleration.
For 32-bit application support, also install the lib32-mesa package from the multilib repository.
For the DDX driver (which provides 2D acceleration in Xorg), install the xf86-video-intel package. (Often not recommended, see note below.)
For Vulkan support (Ivy Bridge and newer), install the vulkan-intel package.
DRI3 issues
DRI3 is the default DRI version in xf86-video-intel. On some systems this can cause issues such as this. To switch back to DRI2 add the following line to your configuration file:
Option "DRI" "2"
For the modesetting driver, this method of disabling DRI3 does not work. Instead, one can set the environment variable LIBGL_DRI3_DISABLE=1.
