Daniel, there are actually two bugs here: the first one being that 3D acceleration doesn't work out of the box using Ubuntu's installation of the Nvidia driver through "additional pilots": for that to work, you need to add “Option “PrimaryGPU” “Yes”” to /usr/share/X11/xorg.conf.d/10-nvidia.conf.
The second bug is that, once this configuration fixed, it's impossible to easily switch between integrated card and dedicated card without rebooting (either through prime-select or with the new gnome-shell's shortcut). Let's say that this report is about the 2nd one, and I've opened a new report for the first one: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1875794 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1875005 Title: [amdgpu] Launching apps on the Nvidia GPU via PRIME does not work (in the presence of an integrated amdgpu) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1875005/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
