Also I am facing a problem after updating the alpha version (which worked OK) to beta version of Lubuntu 14.10 I no longer could get the desktop interface, only a blank screen appeared after a few seconds of showing "Lubuntu 14.10" in the centre of the screen. Reinstalling Lubuntu14.10 beta on the same partition - after formatting - resulted in the same problem. The initial GUI after reinstalling 14.10 beta appeared in the normal way, but after changing the graphic driver to nvdia-304 and update/upgrade the Lubuntu GUI has failed to appear again.
