Re. the bug report in the email thread, they state that "if HDMI cable isn't plugged before boot, the HDMI port becomes useless and never responds to cable hotplugging"
However my situation seems to be the reverse: If the HDMI cable is plugged in before cold boot, then the port appears to work through boot, GDM, and desktop. But on log out to GDM or soft reboot, it breaks. The interesting thing is that the port breaks after log out to GDM, not just reboot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886230 Title: Thinkpad P1 Gen2 HDMI doesn't work after log out or reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886230/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
