Help resetting panels to original layout

system

#1

I’m looking for help on resetting my panels to their default (original) configuration. After “resetting” the menus (Applications, Places, System) are all missing from the upper left corner. The panel dimensions changed as well (taller).

I was troubleshooting the circular red icons that appear when viewing the MATE desktop over VNC (like here). After removing the icons per this answer (which isn’t really a fix), I right-clicked the upper panel and choose “Reset panel”. Instead of restoring the original configuration, it presented the error message:

The panel encountered a problem while loading “BriskMenuFactory::BriskMenu”.

Do you want to delete the applet from your configuration?

[ Don’t delete]        [ Delete]

I choose ‘Delete’ at first, then reset again and chose to not delete. Neither method reproduced the original panel configuration (missing menus).

Turns out the BriskMenu package wasn’t even installed:

[email protected]:~$ apt-cache search brisk
mate-applet-brisk-menu - Solus Project's Brisk Menu MATE Panel Applet
[email protected]:~$ apt-cache policy mate-applet-brisk-menu
mate-applet-brisk-menu:
  Installed: (none)
  Candidate: 0.5.0-7ubuntu1
  Version table:
     0.5.0-7ubuntu1 500
        500 http://ports.ubuntu.com bionic/universe armhf Packages

After installing mate-applet-brisk-menu, resetting the upper panel no longer produces an error… BUT there is still no menu either. Just a blank upper left corner.

This is a 16.04 → 18.04 LTS upgrade, on Raspberry Pi 3.

OK, think I found what I needed in this and this thread. I used MATE Tweak to re-select the (only) option listed for me, “Gnome 2”:

I don’t use RPi, but with my desktop I had a similar issue loosing all my panels. See my post here. I simply used Mate-Tweak and kept cycling through the various panels until my panels returned. No problems with panels ever since.
