I did a fresh install on a partition, made sure the 6.5 kernel was installed, installed the gnome desktop and wayland, then did the following:
1. Booted into kernel 6.5 with Xfce (using Xorg). Result was identical to before, the DisplayPort monitor is shown, but no input detected by the HDMI port monitor. 2. Booted into kernel 6.5 with Gnome and Wayland. Result identical, the DisplayPort monitor is shown, but no input detected by the HDMI port monitor. 3. Booted into kernel 6.5 with Gnome and Xorg. Result identical, the DisplayPort monitor is shown, but no input detected by the HDMI port monitor. No errors are shown that I can see in the logs. The system acts like both screens and monitors are present, I can configure via the Display app as if both are there, but the HDMI monitor never receives a signal. Since the same issue also occurs with Gnome and Wayland, I think that the issue is not as likely to be with Xfce, Gnome, Xorg or Wayland. That leaves the kernel and its modules as the likely suspects. Are there other things you'd like me to try? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/2054212 Title: System starts, but monitor on HDMI has no signal in 6.5 (but 6.2 works) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-6.5/+bug/2054212/+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
