I recently upgraded 2 laptops from Bullseye to Bookworm and no longer
have access to my external monitor from one of them.
My environment consists of a couple of laptops connected to an external
monitor via an HDMI Switch that, until the upgrades, gave excellent
service. The only diagnostic I have is that, from the failing m/c, the
monitor reports that there is no HDMI signal from that computer.
Any thoughts will be welcomed.
Hi, just in case: what's the output of:
$ xrandr
, with everything turned on and connected?
Interesting thought, but no answer. The only output is the internal
monitor and a disconnected VGA port. HDMI is missing in action.
As it was working until the reboot into Bookworm, I think the
possibility of a hardware failure at that precise instant is somewhat
remote, but...
My next step is to find a Live, pre-Bookworm CD and see what happens.
The reason I posted here was to establish if anyone else has encountered
this issue and found a solution.
It seems that it must be a hardware failure. A Bullseye live system
exhibits the same missing HDMI signal and swapping the HDMI cables
eliminated that as a possibility.
Over and out.
