I have a PH4TRX but with a 16:10 screen (2880x1800) not the 'standard' display format you'll find when you search for this type (which is apparently 2560x1600, so a bit confusing). They seem very closely related (see: https://www.notebookcheck.net/Schenker-launches-the- Vision-14-a-light-new-16-10-ultrabook-with-3K-display-options-and- expandable-RAM-storage.544343.0.html )
When I wanted to upgrade from Ubuntu 20.04.2 to 21.04 it at first seemed a bit like flickering, but when installed it was completely unusable. I have not tried with the different boot parameters suggested in the post above, but it seems very comparable. Also maybe comparable with Dell XPS 13 troubles (the fix suggested there doesn't work) https://www.dell.com/community/XPS/Dell-XPS-13-9310-Display-issue-after- installing-update/td-p/7735493 I'll try the suggestion with a startup disk soon and U. 21.04 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938039 Title: Tongfang PH4TUX1 flickering with 3k eDP Display on 5.11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938039/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
