Platform: Ubuntu 22.04 (installed yesterday)

Problem: Running most programs with DRI_PRIME=1 doesn't work. I first discovered it when trying to run Minecraft (MultiMC) because it wouldn't use the discrete GPU. I tried using env DRI_PRIME=1 but it doesn't change anything.
I tried running glxinfo | grep Device to see if it's only a game-related problem:

okonio@rokonio-Dell-G15-5510:~$ glxinfo | grep Device

    Device: Mesa Intel(R) UHD Graphics (CML GT2) (0x9bc4)

rokonio@rokonio-Dell-G15-5510:~$ DRI_PRIME=0 glxinfo | grep Device

    Device: Mesa Intel(R) UHD Graphics (CML GT2) (0x9bc4)

rokonio@rokonio-Dell-G15-5510:~$ DRI_PRIME=1 glxinfo | grep Device

libGL error: failed to create dri screen

libGL error: failed to load driver: nouveau

    Device: Mesa Intel(R) UHD Graphics (CML GT2) (0x9bc4)

Apparently no, and there's an error when trying to launch it with the discrete gpu.
I finally tried glxgears and weirdly enough it's working:

rokonio@rokonio-Dell-G15-5510:~$ glxgears

Running synchronized to the vertical refresh.  The framerate should be

approximately the same as the monitor refresh rate.

605 frames in 5.0 seconds = 120.873 FPS

rokonio@rokonio-Dell-G15-5510:~$ DRI_PRIME=0 glxgears

Running synchronized to the vertical refresh.  The framerate should be

approximately the same as the monitor refresh rate.

640 frames in 5.0 seconds = 127.938 FPS

rokonio@rokonio-Dell-G15-5510:~$ DRI_PRIME=1 glxgears

libGL error: failed to create dri screen

libGL error: failed to load driver: nouveau

Addendum: The graphic card I have is a TU117M [GeForce GTX 1650 Mobile / Max-Q] (running lshw -C display). I have installed ubuntu 22.04 yesterday and didn't change any graphic drivers, but when I go to Additional drivers, it says "Continue using a manually installed driver" and I can't select any different one.
