I downloaded a package thru the synaptic manager. once it finished it advised me to restart the computer, which I did. after that I have not been able to get past the desktop. I have turned the computer on and off several times. sometimes the top and bottom panels appear and sometimes they don't. sometimes the Applications etc titles come up sometimes they don't. sometimes firefox webbrowser and email icon come up sometimes they don't. when they do come up if I click on them the whole desktop freezes up. and I turn the computer off and start again. how can I get past the desktop and use my computer? will I have to reinstall ubuntu? and if so how do I do that?
thank you for any advice.
