My wifes computer is running ubuntu 10.04. Since several days the running programs are not displayed on the panel. With alt tab you can still switch between open programs. Any idea what happened?


Maybe the taskbar (Windows List) has been removed?

Right click on bottom panel, that click Add to panel, select Windows List and confirm.

    I had to use Alt right click (Ubuntu 16.04 and gnome-flashback-metacity) to be able to open the context-menu – rosch Jan 18 '17 at 15:20

Probably you have removed the Window List on the panel.

Right-click on the bottom panel and choose "Add To Panel" - select the "Window List" applet

More than likely the window switcher got removed from the panel. Simply right click on it, and click add to panel. Then drag and drop the applet on to the panel, and it should be back to normal.


Adding more tips : Once you add the 'Windows List' into the task bar and only single folder appears on the bar, right click and remove that folder, soon you remove this new folder from the task bar all the open windows will get appeared on the task bar
