OK, thanks for the tip ! That's what I already tried. WARNING: you should run this program as super-user. Would anyone know how to install nvidia driver and switch to nvidia graphic card ? Any help would be greatly appreciated, even if only moral one -) (ST-2019003060 Bureau) > prime-select queryĪlso, I work under xfce and many setting menus are just not working. And yet, prime-select pretends nvidia is selected : The secure boot mode option is not enabled in the bios and i tried prime-select nvidia with no result. I tried uninstalling the nouveau drivers and blacklising them (see /etc/modprobe.d/nf below) then installing nvidia driver from aptitude : didn't work, then by compiling the driver using NVIDIA-Linux-x86_64-450.80.02.run : didn't work either, at reboot, it is still the intel graphic card which is on with intel driver (see modinfo below). I realized that nouveau drivers were used by default, and activating the second (intel) graphic card (see lshw outcome below) which is much less efficient. I have a Dell Precision 7750 under ubuntu 18 and a Quadro T1000 Mobile.
