I reported the customer issue in the Dell forum post above. Can confirm I have the exact same issue I reported above with a brand new 7740 running nvidia 440.26 (installed via ppa .deb file) and Ubuntu 19.10
Working around the issue by never letting the laptop sleep. It's happened 3 times now. It persists through multiple reboot cycles and takes 1-2 days to go away completely, regardless of reboot. Does this damage the panel? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1835996 Title: Dell Precision 7730 - The screen will be flickering after resumed from "display sleep" (ONLY occurs on AUO UHD#8CJK2 panel) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1835996/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
