I, too have the same issue. I tested with the Ubuntu Gnome DE as well - same issue. It appears to be DVD related, as I can replicate it on 3 different computers (1 Toshiba laptop, 1 no name Chinese laptop, and a Dell desktop) all with 16.04, by using the same DVDs.
Some DVDs mount OK others do not, but it is not an intermittent thing. If a DVD fails to mount once, it fails to mount always. There is a small amount of posting in forums on this matter, so it affects more than one or two people. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1577768 Title: 16.04 some dvd do not mount automatically (but do in 14.04) Status in gvfs package in Ubuntu: Confirmed Bug description: Hi, here is a dvd. And ubuntu 16.04. When I insert that dvd, it does not show anywhere, neither in launcher nor in nautilus. But I'm able to read that dvd using vlc through menu media / open a disc. I can manually mount that dvd with sudo mount -t iso9660 -o ro /dev/sr0 ~/Bureau/dvd/ Once mounted there's a dvd icon in launcher and it appears also in nautilus left panel. That same dvd automatically mounts when running ubuntu 14.04 on the same computer. I have also tested other dvd's on ubuntu 16.04 and *most* of them show / mount as expected. But *all* of them automatically show / mount in ubuntu 14.04.
