I have an Acer laptop on which I run Xubuntu 18.04. Recently I've been having increasing problems with the wi-fi. At first it kept randomly dropping the connection, but allowed me to reconnect. The frequency of these dropouts increased and a few days ago it
got to the point where not only could I not reconnect at all, the available wi-fi networks were not even being detected.</div>

My assumption was a failing wi-fi adaptor. Having identified the type I went on to the Intel website only to find that support for it has been dropped (the laptop is a few years old). It did suggest, however, that combinations of the Fn and function keys might
provide a hardware switch for the wi-fi, as might Ctrl + Alt plus a function key. Really it was clutching at straws but I tried it anyway, with little hope given that the instructions were aimed at Windows users.</div>

To cut a long story short Ctrl + Alt + F1 took me instantly out of the GUI to a command line login prompt. After logging in I ran "startx" to fire up the GUI and that took me to the "first use" screen you get when installing Xfce - no task bar, menu or anything
else pre-defined. Fearing I may have royally screwed up my user interface I did a hard shutdown with the power button and then rebooted. Up came the GUI exactly as I am used to seeing it, with wi-fi working fine and no dropouts since.</div>

I've found nothing in either the Xubuntu or Acer documentation about this particular key combination but it's worked wonders. May just be worth others bearing in mind in case of wi-fi or, possibly, other driver issues.</div>
