I’d assume it won’t, you can always just test it out though. There might be some setting for those timeouts in the Steam-steamdeck settings.

I haven’t done this myself, but I assume you can turn off the display in Desktop Mode. I assume somewhere in the “normal” Linux settings there will be the usual Turn Screen Off after … and Go To Sleep after … You could just set the screen to turn off after 5 mins, then set sleep to never and that should do it.

Check my edited comment, I’m pretty certain my limit was wrong.

• Bloons TD 6: this plays great on the deck, especially with the touchscreen
• Euro Truck Simulator 2: mostly just got it as it was super cheap and I saw some of my friends already have it
• Getting Over It with Bennett Foddy: looked super fun when I saw my friends play, but I don’t really like the controls on the deck

For anyone looking for some other nice games for the deck, I can heavily recommend:

• Stray
• Dave The Diver
• Celeste

I got Euro Truck Simulator aswell, for the same reason lol

I assume the tablet gets its video through standard HDMI/DP over USB-C, hence a USB-A to C adapter wouldn’t work.

If you still want to use the tablet with the official dock, there may be HDMI+USB -> USB-C adapters capable of inserting the HDMI signal into the USB-C connection. I’m not too knowledgeable on this topic, so you may want to resort to some more research of your own.

Also keep in mind (as far as I’m aware) there’s a hard limit on 2 external monitors, unless you use some “trickery” like DisplayLink.

Edit: I’ve done a bit more research and I’m pretty sure that more than 2 monitors are supported. There are two limiting factors here:

1. The GPU in the Steamdeck (custom APU which I didn’t directly find a spec sheet for), will typically have a max of 2-4 displays
2. The physical connection, AFAIK as the Steamdeck only has one USB-C port, this means it has one DisplayPort 1.4 link available. This link can be divided into multiple video streams. I couldn’t find a table for DisplayPort 1.4, but this website has one for DisplayPort 1.2, suggesting you should be able to run four 1080p60 signals at the very minimum.

Now with all this information, as long as your Steamdeck can output to any three screens (ie. two external ones and the internal steamdeck screen), it should also be possible to output three 1080p60 signals to external monitors.

Hm there must be some other problem on your end then. Doing a clean reinstall of Yuzu EA 4176 and then using the newest keys, firmware and update for Mario Kart 8 Deluxe should pretty certainly fix it.

It runs great for me on Steamdeck, with the Yuzu EA 4176 AppImage, firmware/keys version 18.0.0, MK8 Deluxe NSP + Update 3.0.1 + DLC.

The latest yuzu version has a bug with Mariokart multiplayer (I believe this is the one that you’re referencing). It can easily be avoided by pressing L+R on the first screen with any controller that isn’t Player 1.
