The log was cut off so couldn't see that PSR was in fact disabled. You can fix that by passing eg. log_buf_len=2M to the kernel cmdline. Anyways, after a second glance at the logs I see the sink does sometimes indicate that the receiver port was not synchronized. Not sure why the failure manifests at that level with the link otherwise being reported as stable. Looks like we could try to reduce the link rate a bit and still have enough bandwidth for the 4k@60 mode. I'll attach something to that effect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1826125 Title: Dell XPS 13 9380 flickering (Whiskey Lake) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1826125/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
