Sup gamers.
Super new to Linux gaming after a brief stint in 2011-2012 with Ubuntu before I shorted my laptops battery by ripping the screen off (woops)
Anywho, I’m trying to run runelite through steam as old school runescape with the launch options: echo “%command%”; /home/zidane/Downloads/RuneLite.AppImage
First off, no idea what any of the options are doing and searching online is no help so I can’t fix it myself…
But this is my problem… The game (runelite not osrs) opens briefly once, closes, and then opens a new runelite which I’m assuming is making steam no longer think that it’s running old school RuneScape? I’m able to play but I want steam to know I’m playing so number go up on steam while number go up in game.


Try removing the echo call, and if that fails, try running Runelite as a JAR.
You might also want to move your JAR or AppImage to somewhere like /home/zidane/.local/bin for good measure, so it doesn’t get wiped as easily.
I tried to rename to .jar and put that into the steam launch options to no avail.
Would I be able to have an always mounted drive and use /games/ as a root (?) directory? Or would that be a bad idea? Probably a dumb question but I’m so clueless lol
You’ll have to install Java and download Runelite as a JAR (IIRC it’s labeled as the “All Platforms” download option on Runelite.net.
You can definitely set up /games/ as a directory but you’ll want to set it up with the right permissions for your Steam Deck user to access it using the chmod and chown commands.
Details will depend on how you mount your drive though. Unfortunately the power and flexibility of Linux means there’s no single “right” way to do these things.
