Actual behaviour

Any application that tries to notifiy will grey out the app and become unresponsive.

Steps to reproduce the behaviour

MATE general version

1.24.1

Package version

mate-notification-daemon-1.24.2-1.fc34.x86_64

Linux Distribution

Fedora release 34 (Thirty Four)

I can't reproduce a grey-out of applications in an updated f34.

[rave@f34-test ~]$ time notify-send lalla

real    0m0,102s
user    0m0,004s
sys 0m0,004s
[rave@f34-test ~]$ 

Same with using the preview from mate-notification-properties. Or any other application which will send notification. Any chance that another notification daemon from another DE, eg. kde,etc., is istalled and cause problems?

Well, after looking again just now, I've found a way to keep this from crashing

$ /usr/libexec/mate-notification-daemon -r Gtk-Message: 08:49:09.764: Failed to load module "colorreload-gtk-module"

So I installed this

$ sudo dnf install kde-gtk-config

and used the suggestion from the other link, and it works now with no timeouts.

$ sudo cp /usr/lib64/gtk-3.0/modules/libcolorreload-gtk-module.so /usr/lib/gtk-3.0/modules/

Thanks for the quick response, maybe this helps someone else.

I had started out saying no, no other DE are installed. Also, I had this happen on 2 different PC's going from F30 -> F34. One of them I did in single increments, the other was F30 -> F32 -> F34.

I responded a bit too quick.. here is more info.. because now that the notification works, it sends the application into a loop of "Resource temporarily unavailable" errors until it finally just quits. Attached strace:

$ strace /usr/libexec/mate-notification-daemon -r --debug

strace-mate-notification-daemon.txt

/usr/lib64/gtk-3.0/modules/libcolorreload-gtk-module.so

But Mate with a normal installation doesn't need something from kde. So the question is what component from KDE is installed, maybe a theme? Can you please check if kde notification daemon is installed?

Yes, thats exactly what it was. I found some plasma packages and with them removed now, notifications are working again. Thank you for the help!
