That sounds like a different bug. The cause of this bug appears to be related to your HDMI monitor not having a current mode set. Although it does list a 'preferred' mode. That much is clear in the xrandr output.
Failing to set a current mode is most likely a bug in 'libmutter'. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1907870 Title: HDMI monitor detected but black screen (has a preferred mode but no current mode) with Intel UHD graphics on kernel 5.9 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1907870/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
