Annoyingly, I have to report that this morning the display in question worked fine with both the latest stable hirsuit kernel (5.11.0-17-generic) and the version I reported the bug for (5.11.0-16-generic).
If I can find a way to reproduce it reliably, then I'll re-open this bug, but for the moment, maybe close as non-reproducible? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1925675 Title: hirsuit kernel fails to detect monitor plugged into USBC thunderbolt socket To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1925675/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
