Please try: * Installing the proprietary Nvidia driver via the 'Additional Drivers' app. The open source nouveau driver is frequently buggy so I would like to eliminate that from the equation ASAP.
* Looking in your BIOS and see if you can disable the discrete Nvidia GPU temporarily. Does that fix it? ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1937072 Title: Incomplete screen redraws To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1937072/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
