Ultramarine HTPC Pack

The Ultramarine HTPC pack is an additional addon to a standard Ultramarine Linux installation.

HTPC mode transforms Ultramarine into a living room or handheld-friendly experience, allowing the user to switch to a ten-foot compatible graphical shell like Steam Big Picture, allowing the system to be easily used on a Home Theater PC or a handheld Ultra-Mobile PC.

What makes this different from Bazzite?

The key difference from Bazzite is that the system is user-managed and an addon to a standard Ultramarine installation, meaning we need to account for all the variables and configurations that a user might have in their environment including but not limited to:

• User-installed packages
• Display Managers
• Desktop Environments
• System mutability

If you would like a fully-managed OTA-like experience, please consider using Bazzite instead.

Manual Installation

Note

Unless you're hacking on these scripts, the best way to install this is through the Ultramarine tweak option

This will install the metapackage and set up the environment for you.

um tweaks enable ultramarine-htpc

Run make install to copy the scripts to the appropriate directories, then use alternatives to symlink them to the appropriate locations:

sudo alternatives --install /usr/libexec/os-branch-select os-branch-select /usr/libexec/um-htpc/um-htpc-branch-select 100
sudo alternatives --install /usr/lib/os-session-select os-session-select /usr/libexec/um-htpc/um-htpc-session-select 100

Disabling Autologin

If you have previously enabled autologin using the --enable-autologin flag, you can disable it by doing the following:
