P.P.S If you don't care for the Nvidia GPU and just want something that works reliably, you might be able to disable the discrete GPU properly in your BIOS. Just use integrated graphics. Then Linux will never see it at all and there shouldn't be as much confusion.
** Summary changed: - wayland session in Ubuntu 18.04 chooses vmware driver on intel hardware + wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on hybrid graphics system -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1733136 Title: wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on hybrid graphics system Status in xorg-server package in Ubuntu: Incomplete Bug description: I upgraded to 18.04 and I no longer get an option to run a wayland session (17.10 offered both the default ubuntu wayland session and xorg on this laptop). gnome-shell runs under the llvmpipe driver. (Unity used to run when I first upgraded, but now gnome-shell is the only option because the gdm login screen offers no login options.) The upgrade did force me to remove bumblebee and nvidia, but afterwards I manually reinstalled bumblebee and nvidia-387 and reset to using intel via prime-select (installing nvidia changes some of the symlinks so that gnome-shell no longer boots, but "sudo prime-select intel" fixes this). The nvidia-387 modules are blacklisted in /etc/modprobe.d, and bumblebee isn't reporting any errors - bbswitch reports that the nvidia card is off, so I don't think it's an issue with hybrid graphics. (primusrun does work, as well.) Attached are the mutter logs that I generated via the environment variables mentioned in https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1724583 comment #20.
