If you are using VNC to run Selenium tests, it may be hard to see what's going on since by default there is no list of open windows and Alt+Tab won't work.

Solving that is easy:

Install a panel of your choice (like lxpanel) which offers task switching:
```
sudo apt-get install lxpanel
```
(You can't use gnome-panel because it won't start twice -- but lxpanel does a good job)
To have that panel appear on VNC screens by default, edit ~/.vnc/xstartup and add an entry to start it, at the end of the file. For example:
```
lxpanel & 
```
(Re)start your VNC session.
