Public bug reported:
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.
