Ubuntu Karmic – Mac Mini – MythTV
Dec 15th
I gave up on OSX. I could not get the media center working the way I wanted. Plex and XBMC have their bugs, as previously posted, twice, preventing predictable functionality. MythTV for OSX simply is not as refined as its native Linux counterpart. It feels like running Windows applications via wine. I just scrapped OSX for Ubuntu Karmic. Out of the box, off of the cd, things work great. Audio works perfect. What didn’t work? The Mac Mini remote control. I tried for a day to get it to work the hard way. I saw that /dev/usb/hiddev1 was working and displaying data; shown with cat. But lirc would not bind to the device. Ultimately I removed the program, and ran a system update. Problem resolved; clearly a bug report was filed and a resolution provided.
Fanart and coverart work fine. The Linux based fronted is seamless compatible with the Linux based MythTV server. I didn’t even need to input the servers ip information manually. I did have to set the repeat feature, for each key in ~/.lirc/mythtv.
Now all I want is to have MythTV sleep the system and wake the system. I get it to sleep the system by making the halt script sudo pm-suspend. Adjust your /etc/sudoers files to allow passwordless sudo for /usr/sbin/pm-suspend. The halt script is configured in setup-general settings. Waking the computer is another thing that I have yet to get working.

Sudo Apt-Get Update
Nov 26th
The sudo command is a program that is not included in the Debian project, although it is a standard, and well integrated component of upstream distributions such as Ubuntu. The sudo command allows a user to access root functionality, without having to “su” or login to the root account directly. On Debian systems the /etc/sudoers file must be configured in order to authorized sudo functionality, whereas on Ubuntu distributions the sudoers file automatically accommodates system users.
The Apt-Get command is part of the aptitude application, and is designed for package management, and software updating. The application supports dependency resolution, and is analogous in functionality to the yum package management system.
Passing the update argument to the Apt-Get command results in a system update process. This process will contact the configured repositories and compare them to existing files on the local system. If an update is possible, the “sudo apt-get upgrade” command will process the respective program upgrade.
You can enter these commands directly into a terminal. For more information about the terminal, its location, and some examples visit:

All that the previous link will show is the terminal location. Click the applications menu, and in the accessories tab is the terminal. You can also hit alt-f2 to get a applications windows; enter “gnome-terminal” to open a terminal. If you want to change the entire terminal, and not open a terminal emulator press cntrl-alt f1. This will change your entire desktop terminal to a command prompt. Press cntrl-alt f7 to get back to your default shell and desktop.
Debain Etch Sudoers File
Aug 17th
Debian is the root of many Linux distibutions. It is extremely clean, and it great for moderate to advanced Linuxed users. To start with a clean Debain install your going to have to add your user name, to the sudoers file, in order to have expected sudo passwordless superuser access. First to open the sudoers file you will have to login as root: use su Type your root password and login. Then open the sudoers file:
nano /etc/sudoers
Simply add at the top of the file:
User_Alias FULLTIMERS = yourusername
yourusername ALL = NOPASSWD: ALL
Then close the file with control o, control x, exit Now you can run superuser (sudo) command without having to enter a password.
