Public bug reported: This is yet another report of USB storage devices failing to automatically mount on some hardy and intrepid desktops. This appears to be confined to machines that have been upgraded from a previous release.
Things this problem is NOT: * A kernel issue. dmesg reports the drives and partitions to be found. Removing USB 2.0 support (ehci_hcd) makes no difference. * A USB flash specific problem. My external hard drive with both vfat and ext3 partitions will not automount, either. * A udev issue. Device entries are created in the usual places, matching those found on a working hardy installation. * A HAL issue. lshal reports the same new entries on both a working hardy install, and the problematic hardy and intrepid installs. * A Dbus issue. qdbusviewer (from the qt4-dev-tools package) shows items appearing on the system bus used by HAL. * A gnome-mount issue. gnome-mount with a device argument completes the mount as expected, with an icon appearing on the desktop, and nautilus opening a browser window if configured to do so. * A installer related symptom. There is no entry for any of the device names that udev creates in fstab or blkid.tab which can conflict (by considering the device to be a cdrom, for example), which is occasionally a problem created by the installer, particularly on USB device installs. I can confirm that Nautilus is set to mount new hardware and open browser windows. I can confirm that the problem persists if I log in as a newly created user, which suggests that this is not a problem with a legacy setting left in the user's gconf or other settings. Both the new user, and the user created within the older installation are members of plugdev, fuse, cdrom and floppy amongst others. The major difference between the machine that does work, and the ones that don't is that the working machine has a copy of gnome-volume- manager running. If I run gnome-volume-manager on the broken machines, with the -n switch, they exit with the "live and let die" message, which apparently means that some other program (Nautilus, perhaps) is listening to Dbus and handling mounting (according to http://www.mattcutts.com/blog/intrepid-ibex-failing/). Unfortunately, this is as far as I can get. https://wiki.ubuntu.com/DebuggingRemovableDevices desparately needs to be updated to include an overview of the auto mounting process for each of the Ubuntu releases, and we need some way of prying debugging information out of which ever process is responsible for handling automounting now. ** Affects: nautilus (Ubuntu) Importance: Undecided Status: New -- USB storage do not automatically mount https://bugs.launchpad.net/bugs/302679 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
