Enable Advance Menu

Acer's AA1 desktop doesn't display all the apps and options available to you.   To get them all, you need the machine's so-called Advanced Menu.  Press Alt-F2 on the keyboard. This pops up a dialogue like Windows' Run... panel.   Type xterm and hit the Run... button. A Linux command line will appear in a window - type in xfce-setting-show and hit Enter.

XFCE is Linpus' GUI controller, and its Settings Manager will now be displayed.   Click on the Desktop icon then select the Behaviour tab. Check the 'Show Desktop on Right Click' option then close each window.

Now when you're looking at the Acer desktop, clicking the right mouse- or touchpadbutton brings up a menu listing all the apps and utilities you can use. Newly installed apps will also appear here.
