Using prime indicator plus for switching, and lightDM instead of GDM behaves as it should.
With GDM it require sudo systemctl restart display-manager - guess it's a GDM bug. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-prime in Ubuntu. https://bugs.launchpad.net/bugs/1767787 Title: prime-select doesn't switch to nvidia after reboot Status in nvidia-prime package in Ubuntu: New Bug description: After sudo prime-select nvidia, recreate new initramfs and reboot I still land on Gnome using Intel gfx card. I have color LED which provides me information about which card is used. When I check which mode is selected with sudo prime-select query I see nvidia but when I check which card is really used with glxheads I see Intel. For the true switch I need log off from Gnome, switch to virtual console and type two commands: sudo modprobe nvidia sudo systemctl restart display-manager.service After these two commands, I'm able to use Nvidia gfx card under Gnome. In my personal opinion, this solution with switching between cards through initramfs and reboot is a huge step back in the usability of Ubuntu. The previous solution with alternatives was much much better for end user.
