The only evidence of an nvidia driver provided in this bug report is nvidia-installer.log.txt which shows 367.48 was installed in 2016, and the bug tag 'possible-manual-nvidia-install'. Both of which indicate an unsupported driver was installed. I'm just going on the facts provided.
Anyway it sounds like the problem is solved based on your last comment. ** Changed in: ubuntu Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958147 Title: Nvidia acceleration has gone To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1958147/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
