Q. I have a linux box with a windows mount point that lost connection to the server. I can't do anything with it - any time I do a "df" or "ls" command it hangs and takes forever to time out. What should I do, aside from rebooting and disabling that mount.

Q. My netbook is really slow after upgrading to 11.04. Videos are choppy and the computer heats up a lot more. Is there any way to fix that?
A. One solution is to get a better netbook, with a better video card, but its not practical for most of us. A quick way to fix this is on the login screen, to select Ubuntu Classic Desktop. This should bring back the desktop you've had before the upgrade:
