    Hal is interfering with my CD/DVD drive when I want to play + a disc or burn something. How can I stop this from + happening?

    + +

    Applications which are not hal-aware will not be able to + tell hald to stop polling CD/DVD drives when they begin to use + them. Because of this, hald may cause these applications to + abort because two different processes are trying to use the + device at the same time. Applications such as totem, k3b, + sound-juicer, etc. should not be affected as they are + hal-aware. For other applications, you can start them using + the hal-lock command. This command will try and + lock the device in question. If successful, hald will stop + polling the device, and hal-lock will spawn the + desired application. The arguments to hal-lock are + as follows:

    + +
    +% hal-lock --interface org.freedesktop.Hal.Device.Storage --udi UDI --run COMMAND
+
    +

    You can use lshal to determine the proper + UDI value. For example, to run abcde to + extract tracks from a CD:

    + +
    +% hal-lock --interface org.freedesktop.Hal.Device.Storage --udi /org/freedesktop/Hal/devices/storage_model_DVD__RW_DVD8801 --run abcde
+
    + +

    As soon as the application finishes, the lock will be + released.
