Now I've completely lost my wireless connection. The network manager menu has gone from the top-right hand corner of the screen and I appear to have lost the ability to do anything that requires authentication. For example, if I try to install anything from the software centre, clicking on the "install" results in no action at all. Even something as simple as changing the time won't work. I can still do stuff from the command line using sudo, but I'm not exactly a wizard with the command line! Has anyone else experienced this? Regards, Gus </blockquote><div>Hello Gus, As a guess this sounds like a problem with gksudo or libgksu. Assuming you have tried login out and back in again, if you have a wired connection try doing a package upgrade with the command line sudo apt-get update && sudo apt-get upgrade Thank you. </div></div> -- John Stevenson Lean Agile Consultant / Coach <a href="http://jr0cket.com">jr0cket.com</a> | <a href="http://leanagilemachine.com">leanagilemachine.com</a>
