DBus is a solid standard used for a wide variety of services which need to be started automatically, but on demand only, in the background, not specifically at boot. One set of DBus services used extensively in Ubuntu is 'gvfs', the virtual filesystem for the Gnome desktop; if these are permitted to run, polling of hardware including the USB bus will occur, which is likely to interfere with USB MIDI interfaces, eat CPU power, and cause xruns in general. To disable gvfs, go as root to ''/usr/share/dbus-1/services'', rename ''gvfs-daemon.service'' to ''gvfs-daemon.service.disabled'', and rename ''gvfs-metadata.service'' to ''gvfs-metadata.service.disabled''. | DBus is a solid standard used for a wide variety of services which need to be started automatically, but on demand only, in the background, not specifically at boot.

To disable gvfs, become root and run the follwing two commands: |
| mv /usr/share/dbus-1/servicesgvfs-daemon.service /usr/share/dbus-1/servicesgvfs-daemon.service.disabled |
| mv /usr/share/dbus-1/services/gvfs-metadata.service /usr/share/dbus-1/servicesgvfs-metadata.service.disabled |

You can't use this parameter in ''/etc/fstab'' for the root partition, you will have to set it as a kernel parameter. So when using Grub you can add the following parameter to the ''GRUB_CMDLINE_LINUX_DEFAULT'' line in ''/etc/default/grub'': | You can't use this parameter in ''/etc/fstab'' for the root partition, you will have to set it as a kernel parameter.
