USB flash drive does not automount in Linux Mint 17 Mate

[Rufus]

I'm using Linux Mint 14 Mate 64bit.

We have several user accounts on this machine. This bug occurs when two user are logged in. It does not occur when only one user is logged in.

When connecting a flash drive to the front usb port, the drive does not automount as expected. Instead a dialog window appears, saying "Einhängen von Datenträger 2,1 GB nicht möglich". In English that means: "Mounting the volume 2,1 GB is not possible". When I switch to my wifes account at that moment, I can see that Mint 14 tried to mount the flash drive on her account, though it was my account that was active when I inserted the flash drive. On my wife's account Mint 14 says: "authentication is required to mount". When I click "Cancel" and go back to my account, I then get the same dialog box saying "authentication is required to mount". Then I can type my password and afterwards mount the flash drive.

I checked dconf-editor, but found no option to set automount in the nemo preferences. I recognized, that usb flash drives are mounted at "media/username" in Linux Mint 14. In older versions, like Linux Mint 11, flash drives were mounted at "media" directly. I am not sure if this has something to do with the automount problem.

The bug does not always show. In rare cases automount works fine, even when two users a logged in.

Any help for getting back the automount feature is very much appreciated.

Update June 2013: This bug is also present in the newest release Linux Mint 15 Olivia MATE amd64.

Try this: Install dconf-tools using synaptic. Run dconf-editor from terminal. Uncheck the automount option in org->mate->desktop->media-handling.

Yes, I get that too.

To make it more annoying, some times it works (plug in a USB drive, you can mount it) and some times does not (plug in a USB drive, and other logged in users are asked to give a password to mount it first).

Mint 14 MATE, now Mint 15 MATE.

Oh, and unchecking automount (and rebooting) doesn't stop this.

I have the same problem (Mint Nadia Mate) every time there are two users logged in.
It affects partitions on HD too. If the USB port has not been used by the other user, though, everything usually works; that is true for HD partitions too.

Hello this affects me also. On my both computers and only if two users are logged in.

Computer 1:
- Intel Core 2 Quad, 64bit
- Linux Mint Mate 14 Nadia

Computer 2:
- Intel Core i5, 64bit
- Linuxt Mint Mate 15 Olivia

Confirmed in Lnux Mint 17 Mate.

I'm seeing this problem intermittently in Mint 18 (Mate).

dmesg shows the drive and partition are recognised
lsusb and lsblk show the partition
udevadm monitor shows the event
I can mount them manually from the command line
Same problem with flash drives and external disks

Intermittent in that it sometimes works. When it doesn't work, after about 10 minutes there's a pop up saying "time out".

I sometimes see a pop up with "operation pending".

Any clues for me?
