Notification Area not starting anymore #728

Open Tronic69 opened 6 years ago

Tronic69 commented 6 years ago

Expected behaviour

Notification Area is loaded normally which is working since years!

Actual behaviour

After updating kernel and rebooting previously configured Notification Area Applet failed to load. Even after deleting it and tried to re-add it error stays. I also did an "mate-panel --reset" without any change on behaviour. Until reboot everything worked fine.

Output in .xsession-errors: ** (mate-panel:4064): WARNING **: Failed to load applet NotificationAreaAppletFactory::NotificationArea: Zeitüberschreitung wurde erreicht Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged. Warnung der Fensterverwaltung:last_user_time (934543936) is greater than comparison timestamp (2008047). This most likely represents a buggy client sending inaccurate timestamps in messages such as _NET_ACTIVE_WINDOW. Trying to work around... Warnung der Fensterverwaltung:0x1004c4f (Fehler) appears to be one of the offending windows with a timestamp of 934543936. Working around...

Linux Mint 18.3 Sylvia mate-desktop: 1.18.0-1+sonya mate-panel: 1.18.6-1+sonya

If I test it with "mate-panel-test-applet" on local machine I get a timeout and on remote machine with X-forwarding it seems to work.

What happens if you add Notification Area (na) to the mate-panel (mp)? a, popup with warning? b, nothing, no change on the monitor at all

Could you try the following please? Open /var/log/syslog, add na to mp, and copy the new lines here. (Likely it is going to be the same as in .xsession-errors, but if not, it might help.)

When I try to add na to mp I get an popup with an error message (in German) like: Error occured while loading applet NotificationAreaAppletFactory::NotificationArea.

Tried to add a screenshot, but did not work for some reason.

I doesn't matter if I choose "not remove" (left) or remove (right) in popup. Nothing happens in both cases which I would expect, becuase loading failed on add action. So nothing is there to remove. ;-)

I see. That sounds like a segmentation fault. It is really strange, that I am using that same mate-panel version - I'm on mint 18.3 as you are - but I don't have this problem. What kernel were you using, what kernel are you using now? Was the kernel the only package, that you have updated? My kernel version is 4.13.0-32.

Tronic69 commented 6 years ago

I'm not really sure since when it's not working anymore, because this system is used like a server and most times I only work in terminal via ssh on it. Just sometimes I use graphical access to the machine, mostly when I have to reboot it. ;-)

I did several updates in the days before, but most are not relevant to Mate or GTK. Things like PHP, squid, systemd, kernel, etc. I'm not sure which kernel I was using before update, but I think it was 4.13.0-30 and now I use 4.13.0-32.
