Nevermind, the full solution from the link did in fact work for me. Using nvidia-driver-390.
I am copy/pasting the solution here for any other users: 1. Create an xorg.conf file for your nVidia device. All you have to do for this is to launch the command: sudo nvidia-xconfig This will create a file /etc/X11/xorg.conf. 2. Edit the created file /etc/X11/xorg.conf and add at the end the lines: Section "Files" ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg" ModulePath "/usr/lib/xorg/modules" EndSection 3. Save and restart the X server. Now, for the first and second user you should have the nvidia driver in use, with the correct resolution and fast rendering. You can check it using the command: --- Note by JoshuaD: I did not try anything below this line ----- glxgears -info |grep NVIDIA which should return the nvidia opengl version. Note, there is also a problem of slow scrolling in the virtual console (Ctrl-Alt-F1). To solve this, edit /etc/default/grub and set the GRUB_CMDLINE_LINUX variable as: GRUB_CMDLINE_LINUX="video=vesafb:mtrr:3,ywrap" then do: sudo update-grub and reboot. Now, the scrolling speed in the virtual console should be very fast. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760068 Title: Wrong resolution at unlock screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/light-locker/+bug/1760068/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
