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 Kernel Packages, which is subscribed to linux-hwe-6.5 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) Status in linux-hwe-6.5 package in Ubuntu: Incomplete Status in xserver-xorg-video-amdgpu package in Ubuntu: Incomplete Bug description: I have been running with kernel 6.2 without any problems. However, when the system upgraded to kernel 6.5, the system boots, but the monitor connected via HDMI has no signal. The system seems to think everything is OK, there are no errors in the Xorg log, xrandr shows both displays, so does inxi -Fxxxrz. Both monitors are connected via the AMD Radeon RX 6600 graphics card, the LG using DisplayPort, the Benq using HDMI. The Benq monitor will show "No Signal Detected" when the system boots and I log into the desktop. The LG monitor shows the correct display. The Display app will show both monitors as present, it's just that nothing is actually sent via the cable to the monitor. So the monitor doesn't get any signal. If I connect the Benq via DisplayPort and the LG via HDMI, then the LG shows "No Signal Detected". Comparing the Xorg.0.log files from using kernel 6.2 and 6.5, I don't see any errors or indications why the HDMI output isn't sending data. I've attached a tar.gz file with the 6.2 and 6.5 kernel results for the Xorg.0.log, the output of "inxi -Fxxxrz" and "xrandr -q". My current work around is to boot into kernel 6.2, but I would like to see the new kernel functioning properly.
