And I only saw your feedback after I put my last comment in... :O The lspci -k command run from artful shows this:
01:00.0 3D controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Mobile] (rev ff) Kernel modules: nvidiafb, nouveau, nvidia_387_drm, nvidia_387 I've got all those blacklisted though in /etc/modprobe.d/, and "lsmod|grep nvidia" and lsmod|grep nouveau" both return an empty string. (The configuration is pretty much the same in bionic as in artful.) I can't disable the discrete GPU in my BIOS, btw. bumblebee works fine in artful, though, turning off and hiding the nvidia card from gnome- shell, and primus runs an X session using the nvidia card quite happily from within gnome-shell, both under Wayland and X. I guess I should go back to bionic and blacklist nouveau as well as re- remove the nvidia driver and try again? Perhaps nouveau was being loaded when I tried last time. -- You received this bug notification because you are a member of Ubuntu-X, 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1733136/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
