How do I check what GPU drivers are in use?

[vgaetera (Vladislav Grigoryev)]

To tell the truth, I’m not sure as my default GPU is Intel, but you can try the following:

sudo tee /etc/profile.d/custom.sh << "EOF" > /dev/null
export DRI_PRIME="1"
EOF

Or try disabling the NVIDIA GPU in the BIOS/EFI settings.
