Hello,
executed "dnf update" after about 15 days of inactivity.
Updates has brought in kernel 5.2.8-200.fc30.x86_64
But after reboot the system is not able to detect (in the sense of no monitor connection at all seen) when connecting a 24" Dell monitor using an usb-c to hdmi adapter on my laptop and then connecting an HDMI-to-dvi cable to the monitor, that I normally used before.
Tried to reboot two times without effect.
As soon as I restart with previous kernel 5.1.20-300.fc30.x86_64, external monitor detection and usage is ok again.
This is in default Gnome environment and Wayland.
Eg in gnome terminal I have:
$ loginctl show-session 2 -p Type
Type=wayland
and
$ echo $WAYLAND_DISPLAY
wayland-0

Anyone else with similar problems?
If you point me on how to get related log lines in journal in both working and not working configurations, I can get more info.
Seen on several threads that with Xwayland and gnome-shell not so easy to see startup log files...

Thanks in advance,
Gianluca


Thanks for suggestion.
In the mean time I opened this bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1744905

I see at least two other new messages with problems related to external monitors...
