I have Felicia installed and yesterday after watching a dvd, everything went weird. Thunderbird took over 5 minutes to start, Firefox the same, the file manager even longer. The mouse cursor was kept taking seconds to catch up with the movement of the mouse. I tried copying a 10Mb file from one folder to another and it reported a time to finish of 35 minutes, and that's exactly what it took.
I stopped Compiz to see if that would help but it never, I even rebooted but still no joy. Today it still the same, so I decided to do a manual backup to my external, just in case. That's taken the whole evening and it's still not done.
Can anyone advise on anything else I can try before I decide just to delete the partition and start from scratch.
