I installed lubuntu from an alternate CD a month ago. Now when I needed to read some CDs, the CD tray won't open.
It can be opened before Ubuntu boots up. It can be opened after entering
sudo eject -i off from console. But it won't mount any other cd-roms, than just the lubuntu live-cd and lubuntu alternate instal cd, where it was installed from.
"mount: no medium found on /dev/sr0" as output, when try to mount anything else. Problem can't be in corrupted sd's, because othe computer, did recognize them well.
lubuntu VERSION="12.04.1 LTS, Precise Pangolin"
