F28: gnome-shell crashes when using external displays

[Stefan Hübner]

Hi,

I upgraded to Fedora 28 two days ago (May 2nd). My laptop usually is
mounted to a docking station with two Dell displays attached.

Since this morning I cannot start a gnome session anymore. After login the
shell crashes gets back to GDM. In fact it's enough to hover over the top
right drop down menu to crash GDM.

Also interesting: no fonts are displayed when using external monitors.

If I restart the machine without external monitors, everything works
flawlessly.

journalctl reveals the following messages (there's also a core dump, which
I omit for brevity):

maybe, like in my case, the external monitor is being used as an extension of your built-in LCD display? so it appears blank.

my Cinnamon crashes after i login but thankfully it restarts fine. never checked further as i switched to KDE Plasma due to some other reasons.

No, the display is not blank. The login screen is displayed. It's enough to
hover over the top right login menu to crash it.

I have no issues, when the laptop is used without external monitors. I can
live with that for a bit, but hope for help to get my developer environment
back working.

As the message says: an indication of a bug.

See the Debian bug report on a similar issue (Redhat bugzilla seems down)

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=893488

I have a long-standing bug for my display port connection to an
external TV-monitor: the external GPU is a Radeon one, and I workaround
the issue with an HDMI connection to that same monitor. If it helps:
the cached version of the bug report on Google. The workaround in
comment 15:

https://webcache.googleusercontent.com/search?q=cache:KftSjwGHfGIJ:https://b...

To make it work you need an X session instead of a wayland one, so
you can use xrandr.

HTH

(Sorry for my system if it messed up the umlauts in your name)

Sorry

Have you tried rm or mv of ~/.local/share/gnome-shell/extensions. ?

Sometimes new gnome doesn’t support older extensions.

https://bugzilla.redhat.com/show_bug.cgi?id=1575229

Once you can successfully login and launch gnome, you can add back in your
fav extensions.

I don't have that file/folder.

I simply hope some upgrade (xorg, radeon, or whatever) will fix
the issue.

Thanks,

So it’s not that issue for you both.

Sorry. It helped others and closed a BZ :-)
