I want to log off and then shut-down my computer and those buttons are deprecated for me, I would like to change that Power button for log-out instead and the menu items too.
How can I achieve this ?, I'm at DConf
There's a much simpler way to achieve a logout button in Ubuntu Mate.
Simply Right click the main panel and select add to panel. Type log in the box and select Logout. This will add a logout button to the panel.
If you so desire you can remove the shutdown button by right clicking it and choosing remove from panel.
