I installed MATE desktop on a vanilla Ubuntu 18.04 installation that had been upgraded from 16.04, using apt install ubuntu-mate-core ubuntu-mate-desktop
(as per the instructions on wiki.mate-desktop.org/download#ubuntu), because the Mutiny panel layout provides my favorite user experience on a Linux desktop (along with the sadly defunct Unity).
I can apply the Mutiny layout using MATE Tweak, but after a reboot the icons on the top panel appear duplicated, as per the screenshot below:
Additionally, when I press the Super
(Windows) key and the HUD is displayed, it doesn't disappear after I click an icon nor if I press the key again, it just stays like this:
Additionally, if I use a keyboart shortcut - for example, I use Ctrl+R
to open a terminal and Super+E
for file explorer - the corresponding app is launched twice.
This also happens if I reset the panel layout (e.g. by switching to something like Netbook and then back to Mutiny) and then logout and login.
EDIT 1:
I removed MATE Desktop using sudo apt remove --purge --autoremove ubuntu-mate-* mate-*
, rebooted, then apt update
and sudo apt-get install ubuntu-mate-desktop^
, to reinstall as per @N0rbert's suggestion in the comments. However, after rebooting the desktop still has duplicated items (screenshot below). If I use Mate Tweak to change the layout to Mutiny, it displays fine, but after logging out and back in the panel icons are duplicated again.
EDIT 2
I executed dconf reset -f /org/mate/
as suggested, then used MATE Tweak to set the layout to Mutiny, and everything looked fine until I logout/login or reboot, after which the panel icons are duplicated, as shown below:
sudo apt-get install ubuntu-mate-desktop^
. It is correct way of Ubuntu MATE installation. If problem persists, then ping me back. – N0rbert Jul 23 '19 at 20:33
