For people that do not need the external GPU, they could disable it and only use the integrated Intel driver, after fixing a bug that causes non-booting.
In case anyone needs it, here's what I did, after installing the nvidia-384 driver: # Install bumblebee apt install bumblebee # Add my user to bumblebee group gpasswd -a user bumblebee # Switch to the intel card prime-select intel # Add to the grub kernel line: acpi_rev_override=1 sudo vim /etc/default/grub && sudo update-grub # Followed steps 3, 4, 5 from these instructions: http://www.webupd8.org/2016/08/how-to-install-and-configure-bumblebee.html # If you need the ext card and it doesn't work, try various steps from https://wiki.archlinux.org/index.php/bumblebee#Installation to enable it -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to plasma-workspace in Ubuntu. https://bugs.launchpad.net/bugs/1684240 Title: Lagging square around mouse pointer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-375/+bug/1684240/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
