Hello. I already wrote this yesterday, but for some reason it did not appear on the site.
I have 2 videocards - Intel UHD graphics | Nvidia GTX 1650.
And I have a problem with drivers, DRI_PRIME=1 shows me:

libGL error: failed to create dri screen
libGL error: failed to load driver: nouveau

And lspci shows me:

Kernel driver in use: nvidia
Kernel modules: nvidia

But I think should be nouveau?
And in games, the GPU heats up not so much, very weak (59-60-must be 73-max79)
Please help me solve problems with Nvidia. Thanks.
