Just checked the Nvidia web site and they recommend proprietary driver version 304 for your GPU (which also implies versions after 304 won't support it). It appears the reason why Software & Updates told you "No Additional Drivers Available" is because that's also older than any Nvidia shipped with Ubuntu 18.04.
As a next step I would recommend you get the driver that Nvidia themselves recommend and manually install that: https://www.nvidia.com/Download/driverResults.aspx/123709/en-us Annoyingly, Ubuntu 16.04 does offer Nvidia driver version 304 but that Ubuntu release is older and did not ship with a version of Gnome Shell that we support. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1860483 Title: [nouveau, GeForce 7300 LE] screen background overlaid with scan type artifact in red To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1860483/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
