I broke my notifications — how to revert them back to default?

[orschiro]

Dear all,

I believe I messed up my system by installing packages from GNOME and XFCE alongside MATE.

Now, my notifications look ugly.

How can I revert them back to default?

Please see -

How to replace MATE's notification daemon (and customize it!)

This software is dead in Ubuntu 20.04, unless you feel like using an older version of VLC or VLC via snapd. Lack of maintenance and incapability of using Qt4 without removing VLC had made this guide difficult to use, and in my opinion invalidates it from hereon until a solution is found. Apologies for the inconvenience. The specific thing which kills it: x-terminal-emulator output for notifyosdconf: notifyosdconf: error while loading shared libraries: libQtGui.so…

Perhaps this will help.

Thank you!

This brought me into the right direction.

I had to uninstall xfce4-notifyd and make sure that mate-notification-daemon was starting.
