I started having this problem last night. I insert the study guide CD for LPIC-1, and nothing happens in Ubuntu (Running 9.10 Alpha 6) When I eject the CD however; I can see the cd/dvd listed in Nautilus, but only when I eject the cd. I can hear it spin up like the drive is trying to read the CD, but shortly after that it stops. I have tried the CD on my wifes xp laptop and it works fine. I even copied music cd's last night onto this laptop, and it worked with out a problem.

The LPIC study guide arrived last week, and when I put the CD in at that time it worked.

This whole thing seems a little weird.

Any ideas?
