LinHES
LinHES (Linux Home Entertainment System) is a distribution heavily based on Arch, centered around MythTV designed for Home Theater PCs (HTPCs) use. The expressed goal of LinHES is to provide a HES-appliance feel to your HTPC. Most if not all of the system configuration and operation can be accomplished via your remote control. Users can go from a blank system to a fully functional MythTV system in 15-20 minutes. LinHES makes use of mythvantage for easy configuration and modification. There is a service menu accessible right from the mythtv GUI where users can configure most of the machine right from their couch via their remote control.
- Current stable release: R6.01.00 (26-Sep-09)
- Creator/lead developer: Cecil Watson
- Pkg Maintainers/developers: Greg Frost, James Meyer, Nathan Harris

Brief History
The predecessor to LinHES is Knoppmyth (KM). As its name implies, the initial releases of Knoppmyth were based on Knoppix, but the latest incarnations are not, although the brand-name "KnoppMyth" has been retained. From the knoppmyth wiki:
- "Knoppix itself is an adaptation of the Debian Linux distribution, Knoppmyth therefore is another project that has spiralled off into its own domain. These days it would be more correct to call KnoppMyth a specialized and heavily customized Debian derivative, as there is very little Knoppix left."
The first release of KM was on 09-Aug-2003 (R1) and was based on MythTV 0.10. The latest stable incarnation of KM is R5.5 which was released on 06-Jul-2008 and is based on MythTV 0.21.2. The first release of LinHES (R6) went gold (stable) on the 26-Sept-2009, version R6.01.00 being officially released.
Both LinHES and KM can be installed and function on almost any "modern" computer. There are a set of components that constitute the so-called, "Knoppmyth Reference Platform" which is nothing more than a set of hardware that is known and certified to work out-of-the-box with KM. The hardware specifications are completely open and published here.
Development on KM has halted and all efforts are focusing on LinHES. That said, KM R5.5 is still a very robust Mythtv-Distro.

Required Hardware
A LinHES system can use most modern and "semi-modern" hardware. Some users report a fully functional system driven by an antiquated AMD Athlon (800 MHz)/nforce2 CPU/MB. For HD-playback one will need a more powerful CPU or a GPU capable of VDPAU such as an NVIDIA 8400GS, 9500GT, or GF 210. For a complete table of NVIDIA cards and their VDPAU support, see this table. Intel Atom-based PCs are also popular among LinHES users for their low heat output and ultra low power consumption. Again, this low-power CPU needs to be paired with a VDPAU compatible GPU or else view HD content will not be possible. Most Atom MB/CPU combos are paired with one, for example, see offerings by Intel and Zotac.
LinHES can also run in a virtual machine (verified to work in Virtual Box v3.0.10) if would-be users would prefer to test drive it in a sandbox.
R6 Installation Walk-through (Brief)
Boot the LinHES CD or USB media which are both available via FTP download [here].
- Screen 1: Select the "Install or Upgrade" option. If upgrading, you will go directly to screen 10 and everything will be processed automatically based on your backups.
- Screen 2: Select a target file-system
- Screen 3: Select the type of install (Full/auto or Upgrade). Also assign partition sizes for the OS, swap, and data partitions. The defaults should be fine. Users can also select which file-system format is used. Currently the default is for ext3, but other options such as ext4/RFS/XFS/JFS are also available.
- Screen 4: Assign a host-name
- Screen 5: Setup the network options. Users may select from wired or wireless configurations with all the standard options such as dynamic IP/static IP, devices, mtu size, etc.
- Screen 6: Setup host options. Choices here include system configuration (standalone/frontend/master backend/slave backend). Initial resolution (i.e. SDTV or HDTV) and remote configure are also on this screen. The setup GUI contains many options for remote controls that are preconfigured for you. Users also set the option to use or not use mythwelcome on this screen.
- Screen 7: Setup timezone/zipcode
- Screen 8: Setup NFS options if media is stored on a remote NFS share. Also configure automatic updates
- Screen 9: Setup user accounts and passwords
- Screen 10: Sanity check/"Are you sure you wish to continue?" screen.
This concludes the installation. The scripts will take over and in about 5 min you will reboot into your LinHES installation.
