I have a IBM X41 Laptop - not the tablet version - I also have a compatible dock with a cd drive. I installed Ubuntu 9.04 originally with this cd drive. Im now on 9.10.

However a problem I have had for ages is whenever I dock my Laptop, the cd drive is on and spinning, but Ubuntu does not find/acknowledge it. If I restart however, and start up with the laptop docked, The CD drive works!

I would prefer to dock the laptop and instantly mount my cd,and not restart. (mostly due to the terrible restart times 9.10 has brought)
