I got hold of an old computer, and managed to put Lucid on it. At the time, it had an old CD-RW drive in it. Now it's got a brand new DVD +/- RW drive, and Lucid can show me that it exists, but it can't mount any discs. In XFCE, it shows the error 'Method "Mount" with signature "ssas" on interface "org.freedesktop.Hal.Device.Volume" doesn't exist'. The problem is pretty much as described on this page: http://ubuntuforums.org/showthread.php?t=1509538. I would have installed Windows, but I didn't have any working Windows XP discs (or a valid key), and even installing Lucid was rather hit and miss. I can't reinstall Lucid to see if that fixes the problem as I'm not at home, and I didn't bring my Lucid disc (or if I did, it's corrupt). If anyone has idea of how to fix this problem (the computer's for my parents, aren't they're not exactly computer savvy, even with Windows XP), I would very much appreciate a solution. If worst comes to worst, would a complete reinstall work (even if I have to download the ISO again, although I'm not sure I have access to a spare CD). I have until Saturday, which is when I have to go home. Sandy (rather desperate)
