I don't know if this helps: If, after having inserted a video DVD, I right-click eject the CDRW (the second drive) and close the lid again, the DVD drive icon reappears in Places>>Computer and I can right-click eject the DVD (but there's still no icon on the desktop).
It's really strange and it seems I'm the only one affected by this... -- No DVD icon in Places >> Computer and Desktop when mounted https://launchpad.net/bugs/41458 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
