Booting to Steam Big Picture under certain conditions

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Simple bash script set to run once your DE is loaded would do it. Detect the TV with
xrandror equivalent, then start Steam in BPM. If not, do nothing.I’ll probably have to look at the docs but does xrandr assign something like a uuid to displays? I do remember having to set a display manually for one game for Wayland so it launched on the right monitor but I thought I had some issues with the numerical order moving around for some reason. Presumably I’d also want a kvm or something to start the pc from my living room as well and just plug or unplug from the tv itself?
If you just want the machine to do something only WHEN it detects the TV, that's a bit different. You want an HDMI or DP switcher. You can just make a tiny listener for DBUS events that launches BPM when it detects the TV coming online.
