Well, at the time the problem happens, I don't know, as launching xrandr
seems to reinitialize the display setup to what it should be (panel
reappears and all windows restored in visible screen).

Nevertheless, it then says :
$ xrandr
Screen 0: minimum 320 x 200, current 2288 x 900, maximum 8192 x 8192
VGA1 disconnected (normal left inverted right x axis y axis)

Hope this helps.
