Hi, all,
I'm having an odd problem. On two of my laptops, on which I've just
done fresh installs, I cannot get the external monitor to work. Using
either the XFCE display configuration tool, it shows up, but it's
marked as 'disabled'. I do not seem to have the usual such tool under
KDE, which is one of my puzzles.
The install was done the same way in both cases, and somewhat
non-standardly, so I'm guessing I might be missing some package(s).
I've had trouble using KDE with Wayland, so I installed the XFCE
spin, then installed KDE via dnf, so Wayland does not get loaded, and
is not even installed.
Graphics processor on this machine is AMD Renoir. It's a System 76
Pangolin.
What happens if you do the following series of steps?
1) disconnect the external monitor from the laptop, allow the monitor
to continue running
2) restart the laptop and login, then allow it to boot up to a stable
screen
3) plug the monitor cable back into the laptop
Does the monitor obtain the same image as is on the laptop, and allow
you to use them together?
If you have no image look at the output of dmesg, there may be
interesting kernel messages that
help investigate what is wrong.
