My Mint OS crashed after I added MATE panels to each side of my desktop. After the third additional panel, I experimented (played around) with adding a fourth additional panel to see if it would line up below my default panel, which was at the top. Instead it completely covered my first and default panel. So, then I had four blank panels showing on each side of my desktop. Right clicking would not work on any of them in order to get rid of them. No operations were working. (Having a MATE warning about the danger of too many panels would have been appreciated!... of course, maybe I should not have pushed the system so much.)
Have rebooted... a few times. Only one blank panel appears on top covering my default panel with icons. Right clicking does not work. No terminal access. Keystroke commands do not work. Nothing will work, except my mouse moves around. None of my desktop icons appear.
Mint Recovery Mode brings up the same actions (even after repairing packages). However, Recovery Mode brings up a command terminal.
Please tell me:
What terminal command(s) can I use to uninstall my panel(s) and reinstall, thereby circumventing a complete Mint reinstall?
Any help appreciated. Thanks so much.
