Hi Tim, I assume that Nautilus (or Caja in the case of Ubuntu Mate) is actually responsible for the "media already mounted" warning because if you open dconf-editor and go to "org/gnome/desktop/media-handling" (or "org/mate/desktop/media-handling") and change both "automount" and "automount-open" to false then the "media already mounted" warning goes away. The downside is that doing so interferes with mounting usb drives, cameras, etc so it's not a truly viable workaround.
The descriptions in dconf certainly mention Nautilus and Caja specifically: If set to true, then Nautilus will automatically mount media such as user-visible hard disks and removable media on start-up and media insertion. If set to true, then Nautilus will automatically open a folder when media is automounted. This only applies to media where no known x-content/* type was detected; for media where a known x-content type is detected, the user configurable action will be taken instead. If set to true, then Caja will automatically mount media such as user- visible hard disks and removable media on start-up and media insertion. If set to true, then Caja will automatically open a folder when media is automounted. This only applies to media where no known x-content/* type was detected; for media where a known x-content type is detected, the user configurable action will be taken instead. So I really assume that some file managers (Nautilus, Caja, and possibly Nemo) attempt to mount the blank media after gvfs has already mounted it and therefore produce that warning. I'll grant you that it's only a cosmetic issue but it's certainly one of those bugs that just shouts "not ready for prime time" and sends users looking elsewhere for a reliable distro. I'd think there'd be a way to have Nautilus and Caja just see if media is already mounted by gvfs and if so say nothing rather than displaying a useless and meaningless warning. Since this does also effect the Mate DE I took the liberty of subscribing Martin Wimpress, so apologies in advance to Martin. My intention is not to be pushy but only to inform. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1069964 Title: Two processes attempt to mount blank optical discs Status in OEM Priority Project: New Status in glib2.0 package in Ubuntu: Confirmed Status in unity-settings-daemon package in Ubuntu: Confirmed Bug description: This behavior can be reproduced using either a live USB or an installed version of the effected flavors. Simply insert a blank optical disc in the drive. The behavior differs slightly in Ubuntu GNOME as the notification to either Open with CD/DVD Creator or Eject is displayed twice - that is after simply clicking on the X to close that notification it closes but a new duplicate notification appaers immediately. The GNOME Classic session is not effected at all. In all other effected flavors and/or desktop environments a notification appears stating "Unable to mount Blank disc. Location is already mounted". Effected flavors and DE's include Ubuntu w/Unity, gnome-session-flashback, and Ubuntu MATE. Versions effected include Trusty, Utopic, and Vivid. I assume that two separate processes are actually attempting to mount the blank optical media, rather than just the file manager attemting to do so, because both Nautilus and Caja are effected (based on some of the comments below possibly also Nemo). While purely cosmetic in nature I'd certainly be willing to try and troubleshoot this if someone more tech savvy would provide some debugging instructions.
