Description

Hi Willy,

I have run into a problem in the last day. Mate-notifications stop working after a few minutes which causes programs that use them to freeze until the notification times out. makemkv, thunderbird, network-manager, to name a few. I am not sure why it seems to work fine when first logging in, but after about a minute or two it just stops. I opened mate-notification-properties and tested it and got time out errors. I'll attach screenshots of the errors. Any help here is appreciated.

i have rebuilt mate-notification-daemon several times to find a solution for this which build did you have in your machine?

Right now build 3, I can't seem to find what is killing the daemon. After I restart it and everything is fine, but then it dies again.

Possibly relate here?: https://github.com/mate-desktop/mate-notification-daemon/issues/184

So basically it's a race condition on who got the dbus session since there's only 1 dbus name for all DE. What i did is to add cron entry to run mate-notification-daemon -r to replace existing dbus with mate-notification-daemon

this is an old bug issue: https://bugzilla.redhat.com/show_bug.cgi?id=1490959

I am reading up on it, so If I am understanding it correctly, plasma5 and mate are basically tripping over each other for notify-impl?

[mdinslage]

As a temporary workaround, I renamed /usr/share/dbus-1/services/org.kde.plasma.Notifications.service to /usr/share/dbus-1/services/org.kde.plasma.Notifications.service.old. Probably not the best solution, but I don't have any plans to use KDE5 so this should suffice.

Willy I did see this https://bugzilla.redhat.com/show_bug.cgi?id=484945#c40. I will look more into this tomorrow.

That's why i put a cron job and a desktop file to be started when it's loaded so it replace the current notification daemon available by issuing mate-notification-daemon -r

i have Plasma 5 and MATE and it works fine here with BUILD 3

This might just be specific to my machine then, when the daemon stops after 30 seconds of inactivity it just wont come back. Getting plasma notifications out of the way fixes it. I'll mark this as solved since I can workaround it. I will test what I read in the above post and if renaming the plasma notification won't break KDE I may ask pat to issue a patch.
