GPU acceleration only works with MESA v23.2. In order to get them to work (Bookworm):
- Add ‘deb https://deb.debian.org/debian unstable main’ to the sources.list
- sudo apt update && sudo apt -t unstable install libegl-mesa0 libgl1-mesa-dri mesa-utils mesa-utils-bin
- Remove the line added in sources.list, then sudo apt update
- Reboot the system.
