Hey folks! Gamescope doesn’t seem to pickup my external monitor when plugged to it via a USB-C adapt

Hey folks! Gamescope doesn’t seem to pickup my external monitor when plugged to it via a USB-C adapter which has an HDMI port. Is it a bug, or is it just not built-in Bazzite right now?

RRobotta any explicit sync patches?

Kyle Gospo•3/3/24, 9:45 PM

yes the xwayland one is present

Robotta•3/3/24, 9:45 PM

okay, thank u

should work fine, that's standard steam deck docked use case

Kyle Gospo•3/3/24, 9:45 PM

which I can confirm works on my end

jipiboilyOP•3/3/24, 9:46 PM

Doesn’t seem to work with my Legion Go. Pretty standard Anker adapter.

works in desktop?

jipiboilyOP•3/3/24, 9:46 PM

I was looking at the code base very quickly, to try to figure it out. Is this file a good starting point? system_files/deck/kinoite/usr/bin/startplasma-steamos-oneshot

does your qam have a vrr slider?

jipiboilyOP•3/3/24, 9:47 PM

Not even the way it’s launched and where it detects the display?

jipiboilyOP•3/3/24, 9:47 PM

No idea what your ‘re talking about

antheas•3/3/24, 9:47 PM

it will be disabled

antheas•3/3/24, 9:47 PM

but does it have it?

jipiboilyOP•3/3/24, 9:48 PM

Context: software engineer, but hasn’t run Linux as my daily driver in 15 years or so.

KKyle Gospo that's gonna be https://github.com/KyleGospo/gamescope

jipiboilyOP•3/3/24, 9:48 PM

Will look into that.

Release v1.3.14: Legion go kernel patch hotfix · hhd-dev/hhd

A new legion go kernel patch improves the deadzone of the legion go gyro. However, it also changes the raw values of the gyro, which nulls the previous jitter hotfix. This update fixes it.

And just to be sure, you say it works on your Steam Deck with Bazzite? Plugging and unplugging swaps display properly? If yes, any pointer on where I should look first in those repos? If you don’t know it’s fine. If you know from the top of your head, I would take the tip

Kyle Gospo•3/3/24, 9:50 PM

yes

Kyle Gospo•3/3/24, 9:50 PM

I wouldn't know, this is all stock behavior from Valve

Kyle Gospo•3/3/24, 9:50 PM

gamescope-session is nearly unmodified as well

you could start by answering my question

jipiboilyOP•3/3/24, 9:50 PM

This question?

antheas•3/3/24, 9:50 PM

yes

jipiboilyOP•3/3/24, 9:50 PM

I don’t know what it means, so can’t answer

jipiboilyOP•3/3/24, 9:51 PM

But I will@look jnto figuring that first I guess hehe

antheas•3/3/24, 9:51 PM

Is there on the side menu a slider that says Enable VRR below the screen hz?

jipiboilyOP•3/3/24, 9:52 PM

Probably not as the Legion Go screen doesn’t support VRR IIRC

jipiboilyOP•3/3/24, 9:52 PM

Booting to look

antheas•3/3/24, 9:52 PM

no dice, looked at the quirks

antheas•3/3/24, 9:53 PM

but if it had it that'd have been an easy solution

antheas•3/3/24, 9:53 PM

that slider appears if the display is set to external which disables docking

antheas•3/3/24, 9:53 PM

fyi

jipiboilyOP•3/3/24, 9:53 PM

Ah good to know!

antheas•3/3/24, 9:53 PM

i want to say the quirks look correct

KKyle Gospo gamescope-session is nearly unmodified as well

jipiboilyOP•3/3/24, 10:10 PM

Thanks! I’ll look into understanding what happens and try to find a hacky workaround first.

antheas•3/3/24, 10:12 PM

it should work

Kyle Gospo•3/3/24, 10:13 PM

They support it officially, the problem is nobody else does

Kyle Gospo•3/3/24, 10:13 PM

They dumped it onto the various DE's laps and just said "here's stable, fuck you"

Kyle Gospo•3/3/24, 10:13 PM

Very Nvidia move.

Robotta•3/3/24, 10:14 PM

Lmao

Robotta•3/3/24, 10:14 PM

Pretty classy nvidia stuff

Robotta•3/3/24, 10:14 PM

My only hope rn is seeing this getting merged:
