Hi, since trying to update my Linux via the live update tool, a few things have gone wrong. I can not access the power center now, my battery icon has disappeared, and I can not access Pirut (add/remove software) I dont know if pirut worked prior to the update, as I never used it, but I wanted to check it out to see if it had the power center (kpowersave) as a downloadable so I could try and sort it myself. When I try and execute Pirut, it asks for my root password, I type that in, but then nothing. When I try to access power center from the desktop menu, nothing happens. When I try to access it from /usr/share/applications it tells me: Failed to execute child process "kpowersave" (No such file or directory). Does any one have any ideas please how to either get into Pirut or kpowersave? Could pirut fail to load as I am connecting via a usb dongle and have not set up a permanent internet connection? help please!
