I have a very strange problem.
I had Ubuntu 9.10 working well on my desktop - after updating to 10.04,
it would not recognise my mouse or keyboard - they are not usb, they are
the older plug in types (?ps2). When I plugged in a usb mouse, and
rebooted, both the usb and old devices worked intermittently. I then
plugged in a usb wireless keyboard and mouse and all was well for a
while but now both have ceased to function - I just get a stationary
arrow and no way of accessing anything. They all work perfectly if I
boot into windows as this is a dual boot computer. Any ideas?
