    How to get help

    If you have a question or a problem with Mythbuntu, the following items will help you to request support in an efficient manner:

    • Make sure your new thread has a meaningful title. Just "Help! MythTV is not working" isn't helpful.
    • Complaining that the new version of Mythbuntu/MythTV "sucks" isn't going to help anyone. In fact, it'll make it a lot less likely that you receive support. Remember, nobody is obliged to help you unless you paid them for it. Even if you're frustrated because the problem you're experiencing is very annoying, please be polite. Thank you.
    • Please remember to search the forums and the Internet before asking here. Often, a question has already been answered.
    • Please state what version of Ubuntu (7.10 or 8.04) you are running.
    • Please state what version of MythTV you are using. Open a terminal and type
      apt-cache policy mythtv-common
      to find out. You can also use your favourite package manager.
      Just saying "0.21" isn't helpful because the MythTV packages often receive bug fixes so it's important to know the exact version.
    • Please provide log files. The log files for MythTV can be found in /var/log/mythtv/.
      If you think your problem is backend specific, you can find the log files for mythbackend in /var/log/mythtv/mythbackend.log.
      The frontend logs to /var/log/mythtv/mythfrontend.log. If you're using Mythwelcome, /var/log/mythtv/mythwelcome.log is the right place.

      To access these log files, just open them in your favourite editor or bring up a terminal and type
      less /var/log/mythtv/mythfrontend.log
      Of course, you need to substitute the correct file name here.

      Sometimes, the log files will already contain instructions to fix the problem you're seeing so it's beneficial to look over them before posting. If you're experiencing a more general problem, like no video playback when you go to 'Watch TV', it's a good idea to post information from both the frontend and the backend log.

    Extra credit
    • If you're feeling that your log files don't provide enough information, you might benefit from increasing the verbosity.

      mythfrontend -v help
      to find out about the available verbosity levels. After you've chosen some, for example "important,general,audio", proceed with the instructions below. Please note that you have to prepend "--verbose", so an example line might look like --verbose "important,general,audio".

      • mythfrontend: If your mythfrontend starts automatically on boot, you should edit /etc/mythtv/session-settings and adjust the MYTHFRONTEND_OPTS variable in that file. Please note that it'll be necessary to uncomment that line by removing the # symbol at the beginning of the line.
        If you're starting mythfrontend manually, then just open a terminal and type
         mythfrontend --verbose your,verbosity,flags
      • mythbackend: edit /etc/default/mythtv-backend and adjust the EXTRA_ARGS variable. You'll likely have to uncomment this line by removing the # character at the beginning of the line.

    Debugging Crashes
    Sometimes, the frontend or the backend will just exit without giving any useful error messages. That's often caused by bugs in MythTV. Often, you'll find a "segmentation fault message in the log files or in dmesg. To debug these crashes, a crash report needs to be send to Launchpad using a tool called "apport".

    • First, enable apport.
      • edit /etc/default/apport and set enabled=1. Apport is usually disabled on stable Ubuntu releases and enabled by default only on the development series.
      • run
        /etc/init.d/apport start
        in a terminal to initialize apport
      • it is also a good idea to install the apport-gtk package to give you some nice pop-ups when something crashes.
        sudo aptitude install apport-gtk
    • Now, try to reproduce your crash.
    • Once your application has crashed, you should get a window telling you that something went wrong. You can file a bug report then. If you opted not to install apport-gtk, you can run
      in a terminal to send a bug report.
    • Once the bug has been reported, the Mythbuntu developers will look at it and forward it the MythTV developers unless there was a problem when creating a backtrace from your crash report.
