After some researches I find two ways to have HDR pass through on Linux x86: Libreelec and kodi “stand alone session”.

For kodi I find this thread, so I installed kodi-gles on my Arch system; then I started a tty and launched kodi with kodi --windowing=gbm but the interface doesn’t work, it seems stuck, but I can go beck to the tty.

For Libreelec I downloaded the latest generic image for x86 system and I flashed it on a 8GB USB stick (I tried with balena etcher and Ventoy). So I tried the run and live option but with both the system is stuck on the Libreelec splash page (in the run case the system is stuck after the installation).

Can anyone help me?
