Is it HDMI from the board to HDMI on the monitor? I'd like to rule out any use of an adapter or HDMI-to-DVI cable.
What monitor is this? Is the monitor detected? What do you see in the 'status', 'enabled', 'dpms', and 'modes' files in /sys/class/drm/card0-HDMI-A-1/ ? -- 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
