Public bug reported: I'm running Xubuntu 14.04.3:
3.13.0-57-generic #95-Ubuntu SMP Fri Jun 19 09:28:15 UTC 2015 x86_64 GNU/Linux DISTRIB_ID=Ubuntu DISTRIB_RELEASE=14.04 DISTRIB_CODENAME=trusty DISTRIB_DESCRIPTION="Ubuntu 14.04.3 LTS" thunar: Installed: 1.6.3-1ubuntu5 Candidate: 1.6.3-1ubuntu5 Version table: *** 1.6.3-1ubuntu5 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages 100 /var/lib/dpkg/status with all the latest updates. I run this on three different machines - my home desktop, my work desktop and my home laptop. As of about two weeks ago, I upgraded my home desktop to an Intel base, and last week it stopped automounting any USB disk/flash drives UNLESS Thunar is also running when I plug the drives in. (My work desktop is also an Intel base and this never happens there.) This happens for my usual flash drives and also my SATA-USB3 conversion plug-in tray. When the drive plugs in, it shows up in lsusb, but the notification never appears, df does not see it and I can't access it normally. I discovered that, if I am not running Thunar when the drive is plugged in, I can run it, then click on the drive icon in the left vertical panel, and that mounts the drive. If I am running Thunar, it mounts (semi)automatically with full notification, just like it used to without Thunar.. I have checked the Removable Drives and Media panel of settings, and the Mount removable drives when hot plugged and Mount removable media when inserted boxes are both checked. What I expected to happen: The drive mounts and is visible in df and accessible for all normal commands. What happened was: The drive shows up in lsusb but nowhere else unless Thunar is running or I start it up and click on the drive name. ** Affects: udisks (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1492534 Title: USB devices fail to automount unless Thunar is running To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udisks/+bug/1492534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
