Hmm… no idea then, sorry mate

Are you using Nvidia, if so that might be why I am running it just fine on an AMD gpu on wayland using Nobara

For that the recommendation is ALVR

These days you can merge the SD card with your internal storage which will allow you to install apps on it albeit they will run more slowly off the sd card instead of off the phones flash storage but better than when it could only be used for files
