It just happened; Mesa 22 is now in Ubuntu 22.04.
If you need older drivers like for Intel Arrandale GPUs then my immediate recommendation would be to stick with Ubuntu 20.04 instead.
Alternative solutions that may work with Ubuntu 22.04 are:
- Multiple versions of Mesa installed.
- The “crocus” driver: Try
MESA_LOADER_DRIVER_OVERRIDE=crocus
in/etc/environment
and let us know how you go. Or is it loaded by default now?..
