The TV doesn't function correctly compared to Windows on Linux, After clicking play nothing happens and when you click play a second time it freezes the game and you'll have to quit and relaunch. I've already tried using Desktop Mode as sometimes modified local files don't work when in Gaming Mode which didn't work.

I've posted this on reddit already but I really want to find help so other Linux users don't have this problem. https://www.reddit.com/r/Voicesofthevoid/comments/1bfuasx/cant_use_the_tv_linux_steam_deck/

Yeah I've been having the same problem here too. Using it via proton on steam, and although everything else in the game works fine, the tv is the only thing that I haven't been able to figure out.

I've tried changing the proton version to Proton-Experimental and also using Steam Tinker Launch and changing it to ProtonGE but nothing has really helped with this.

Oh hey, update for anyone else looking at this: del found a solution!

In steam settings, add launch arguments and set it to:

WINE_DO_NOT_CREATE_DXGI_DEVICE_MANAGER=1 %command%
