I do not know how to debug it further but I suspect the bug is in the support of later version of the HDMI standard. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761751 Title: Black screen on 18.04 + AMD RX460 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761751/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
