@Evv1L in my opinion, it's pointless to even bother with nvidia on t440p/w541. libreboot disables it, and does intel-only for graphics.
the nvidia binary driver is no longer maintained for that one, so you have ot use an old linux distro. there is a hack on AUR that makes it work on newer kernels but it's still proprietary software.
and with the nouveau driver, performance would be about the same as just using intel graphics anyway.
