This is really awesome.

What OS did you flash on that Pixel6 to get it working? Or are you using a linux vm on an android phone?

Let me know how it goes.

Another feature that might be useful in the arsenal is that you can purposely downclock the refresh rate of the gamescope session when the window is out-of-focus, which means you can put less burden on the computer when multi tasking. Obviously the game will run at a lower frame rate when focus is away, but this might be OK if you want to free up more system resources for watching videos.

But like the other use said, a good place to start is making sure hardware accel is on within Firefox (or whatever browser you’re using.)

Right now it is ESO and nothing else, when she tries the whole system lags until she can move the mouse painfully slowly to the browsers X.

Maybe you should consider using gamescope? This is what the steam deck uses internally to isolate games so that they fight with the window manager less often.

On KDE Kubuntu, you should have no problem installing it if you’ve installed steam as a .deb from the website. Basically, install it either from source or repo (whichever is recommended for ubuntu) and then modify your steam game settings to something akin to the following:

gamescope -f -- %command%

This will launch the game in an isolated WM so that it interferes less with your existing window manager. There’s a tonne of settings, so gamescope --help might give you more details.

Steam is apparently working on making this easier to access by supplying it with all steam installations in the future, IIRC, but work there isn’t finished yet.

If you have the lid closed, you’re looking at 3 to 15 watts to have a laptop running in the background doing some basic server shit.

Not all laptops make effective use of power with the lid closed, sadly. Not saying this as a correction, but for others to know that they need to make sure these settings are available in the bios of the system they are buying.
