No crash in this case, but I made the mistake of toggling to fullscreen mode on my netbook running Ubuntu 12.04. It's now impossible to escape this "No Menus" view, and it seems to have disabled the popout unity launcher as well. Steps I've already taken:
- Alt-Tab to move to a different program, then back - QGIS remains in fullscreen
- Alt-V, Ctrl-F and F11 get no response
- I've unistalled QGIS, deleted the /.qgis/ profile data folder, and reinstalled. Still launches fullscreen
To add to the weirdness, it now launches - still in fullscreen - into a different workspace than the active one.
I realize this has the sound of a Unity problem, but it's just this program that has a malfunctioning UI.
Thanks to all the crew; this in no way changes my opinion of QGIS as an essential tool.
