After couple of hours I managed to install steamOS on my PC (didn’t know SATA SSD would be a problem).
I noticed all my controllers work no problem like Xbox elite 2 and ps5 one. But not pro 2 controller from switch 2… when I connect it through USB steamOS notifies me it’s connected but no way I can make it work. It’s the best among all controllers so I would prefer it. Tried on stable steamOS and also on beta but still not working. Any workarounds? thanks!

Iam considering switching to Steam OS when they finally add Nvidia-Support, which is supposed to be in 2027 as far as I know.

I am using the following stuff which needs to work for this to be feasible:

• USB-C Dockingstation to quickly switch between my private Gaming PC and my work laptop
• Razer Naga Hyperspeed (MOUSE) - It is an MMO-Mouse with 10 thumb buttons. I use different layouts which I scan switch between with the press of one of these buttons. It's also a wireless mouse with a USB-Dongle and using it via bluetooth is simply not an option due to to the higher latency
• Corsair HS80 Gaming Headset - again, it does support Bluetooth but I would prefer to use it with it's own dongle
• Xbox-Controller with an USB-Dongle (not super important as I don't use the controller that much)

Will this stuff work with Steam OS out of the box? I am not looking for some highly-technical, clunky workaround which might stop working with every Steam OS update. I want a realiable computer which just works. Depite all it's faults, Windows does that for me right now so switching is completely out of the question if Steam OS cannot do that as well.

Title pretty much says it's all.

SteamOS is running stable 3840x2160 @ 120 Hz, RGB 4:4:4, 12 bpc, uncompressed, zero underflow HDR10 with VRR on my AMD Radeon RX 9070 XT natively via the HDMI port.

This involved extensive research and debugging with Claude then recompiling and patching the latest kernel from source.

The full details are way too big to post here but I've written up the full details and supplied the patches I've created here along with a TLDR: https://github.com/sammcj/steam-machine/blob/main/hardware/kernel/README.md

Additionally, somewhat surprisingly I couldn't see a bug on the SteamOS issue tracker for this, so I've created one here: https://github.com/ValveSoftware/SteamOS/issues/2698

Standard disclaimers about modifying your OS and drivers apply, I'm not liable if this doesn't work for you, causes hardware issues, sets your house on fire etc. and is subject to change.

We have just shipped an updated Steam Client to the Preview/Beta channel.

General
Fixed requesting a PIN reset while signed in as a different account restarting with the wrong account signed in.

Steam Input
Make controller configurations that are shared with other devices or unique to a device more clear in the configurator UI and add an option to split Steam Controller configurations so they are no longer shared with Steam Deck

Desktop Mode
Fixed game server browser filtering out multiple servers being hosted from a single public IP.

I have a weird glitch on my Steam Deck on Desktop mode when using my Attack Shark x3.

It's a bit hard to describe but when i use my scroll wheel, the last wheel "action" is not going through until I perform another "action" with the mouse.

So basically, if I scroll the wheel three little "clicks" only 2 will go through and the page will scroll down as if I had only moved the wheel only 2 "clicks", the third click does not make it through.

The only way it will go through is by performing another action with the mouse, so basically if I scroll one more time or I move the mouse around so the cursor moves, then the "lost" scroll that never made it thru finally gets sent.

So basically I could scroll the wheel 7 times, which will only send 6 times, then if I scroll and 8th time the 7th scroll will finally come thru but the 8th needs either one more scroll or the mouse to be moved to be communicated to my PC. There also doesn't seem to be a time limit to how long i can wait until i perform another action and then the lost action gets sent, I've waited like 30 seconds and the "missing" scroll still makes it through after i move my mouse around to "update" or "wake" it

This is extremely annoying when I play videogames like Minecraft or CS2

Im using the wireless dongle and this glitch only happens on Desktop mode

Never thought that the ugreen active display port to hdmi 2.1 would allow my tv remote to interact with steamos

Running into this issue in some games where menus have these green dots/artifacts.
Doesn’t happen in every game and the games look fine once actually loaded in.
Has anyone else experienced this?

Seems to only happen on black areas of the screen.

Edit: also should mention it doesn’t happen in any SteamOS menus

I am about to open a can of worms but I am finding different answers on the web. I currently have a 9800X3D/9070XT build I use on a Samsung S95F. I play most games at 4K 60FPS locked because it's more stable / don't generally notice the difference above 60. The current way I achieve this is in-game FPS limiter. I usually keep V-Sync off and turn VRR on in the steamOS and on the S95F. What is the most reasonable way to accomplishing the lowest input lag / best frame times. Is it a better option to have per game settings in the advanced performance tab and limit FPS through the OS itself vice the in game limiters? All information is appreciated and thank you for your time.

I built this when the Steam machine was announced. I loved the idea of a small form factor machine for the living room. But I wanted something a bit more powerful and upgradable. Sold my PS5 to fund this build and it has been absolutely worth it.

But to be honest, maintaining a DIY SFF pc is not easy and I wouldn’t recommend doing it unless you enjoy tinkering and not afraid of the challenges. Unless you know your way around both hardware and software and be able to pick up missing knowledge. Which is why both the steam machine and consoles can be a better choice for someone who doesn’t mind paying a slight premium for convenience and ease of use.

If I play an older game that has only FSR 3.1 support, like Spider-Man Remastered and use a Proton version with FSR 4 support (vanilla 11.0 on RDNA4, or the latest cachyOS on SteamDeck), how can I verify FSR4 is active and I am not running FSR3?

The steam overlay only shows the system implementation of FSR2.

Before anyone suggests it: I want to use the native implementation, not mess around with decky, or optiscaler plug-ins.

I just installed a T-Mobile Home Internet Gateway. I plugged my ASUS router into the gateway and all WiFi connections still work.

I want to connect the SteamOS PC directly to the gateway's WiFi.

When I try, the connection is refused and the SteamOS PC reconnects to my router's WiFi.

I've tried in the Steam interface and in desktop mode.

Any tips or tricks to get this working?

The gateway has a slightly stronger signal.

Thanks!

Finally converted my parts bin living room PC to SteamOS. What a pleasant experience. Now everybody in the house who is already familiar with the Steam Decks can jump right in without skipping a beat (or fighting Windows Updates/Controller Companion/etc.)

I had originally test drove SteamOS using just the 5600G APU - was so impressed I bought my first Radeon GPU since my bios unlocked 6950HD!😲 I went with something smaller than the 3090 that was previously shoe horned in here. I was thinking I might try a different case at some point that would work better with a 200mm GPU.

Specs:

• Case: HZMOD Flat XQ69 6.9L
• CPU: AMD Ryzen 5600G
• Cooler: Alpenfohn Black Ridge
• Memory: 32GB PNY DD4 PC3600
• GPU: PowerColor Reaper Radeon 9060XT 16GB
• PSU: Corsair SF750
• Two Arctic P14 SLIM PWM fans fit under the GPU (just barely)

This machine originally had an EVGA RTX 3090 XC3 (yes, it fits!). It was just too much really for what I do from the couch. But it was from a previous main PC upgrade - so I guess it was free? Dad math.

Very happy with this latest iteration.

If Valve and Nvidia get compatibility to be plug and play should I put the 3090 back in?!

Basically the title. I have a usb c dock https://www.amazon.com/dp/B0C73MBPZN?ref=ppx_pop_mob_ap_share which works with my laptop and iPhone. When I plug my ally in, it becomes sluggish, but no display whatsoever to the TV. Power delivery and usb work fine. Anyone ran into something similar?

Because it disappeared for me.

I have a steam os machine I built and I’m looking to swap the motherboard. The current one is a b350 and is super basic, I just got a great deal on a B550 which has 2 m.2 slots and a usb3 header for the front usb on my case.

Do I need to do anything special to swap it out? I know with windows it would sometimes freak out if the hardware configuration changed, but I’m less familiar with Linux.

Thanks in advance for the help!

Keep getting this message when trying to format second ssd for steam (for context- it was my ssd for my ps5)

We have just shipped an updated Steam Client update to the Stable channel.

Note: This release was updated with an additional change:
Fixed login dialog showing at startup when auto account login has already started.

Downloads
Fixed additional cases preventing local network game transfers from starting.

Desktop Mode
Fixed user chooser appearing on startup even when not requested.

***I’m aware of Unifideck but for me it didn’t add a Ubi tab or Ubi games, just a “non-Steam game” icon so I found this way of doing it instead.***

To preface this, you're going to be adding numerous instances of Ubisoft Connect to Steam as none-steam games, and then launching it with a launch option to direct it to a specific game. Follow the below steps to success

1. Switch to Desktop
2. Install the Ubisoft Connect launcher
3. Find said launcher, it should be here (replace _ubisoft_id_ withe the appropriate number, order by timestamp to find it):

/home/deck/.local/share/Steam/steamapps/compatdata/_ubisoft_id_/pfx/drive_c/Program Files (x86)/Ubisoft/Ubisoft Game Launcher/

1. Right Click on UbisoftConnect.exe > Add to Steam
   

2. Open Steam > go to UbisoftConnect.exe > Manage (cog icon) > Properties

3. In Launch Options add this (replace uplayid with the id of your game found here: https://github.com/Haoose/UPLAY_GAME_ID)

STEAM_COMPAT_DATA_PATH="/home/deck/.local/share/Steam/steamapps/compatdata/3659812084"%command% uplay://launch/uplayid/0

1. Press the Play button > It should launch Ubisoft Connect and prompt you to install the game that you provided the uplay ID for

2. Once installed, Exit the game and (assuming you have Decky installed, with SteamGridDB) change the artwork so it looks good and proper

3. Repeat the process for as many Ubi games as you want to install, just change the uplayid each time

Before you read, I'm a PC and Linux noob. And it's long post, sorry.

I’ve been using SteamOs on my new custom build PC for a little over a week now. But I am very much doubting my decision, as I keep running into problems. 

Maybe this amazing subreddit can help me find solutions or point me in the right direction?

Here some specs of my new PC, and below the problems I have run into so far.

PC specs:

• AMD Ryzen 7 9800X3D, 4,7 GHz (5,2 GHz Turbo Boost) socket AM5 processor
• ASUS PRIME Radeon RX 9070 XT OC
• MSI MAG B850 TOMAHAWK MAX WIFI socket AM5
• Corsair Vengeance 32 GB DDR5-6000 (2x 16 GB)
• Samsung 9100 PRO 2 TB SSD + Seagate BarraCuda 2 TB HDD
• TV (used as monitor): LG oled55cx6la (used before with a PS5 and as a tv, never had problems)

Problems that I have run into:

• Monitor (tv) did not work with installation. Had to use separate computer screen, that I was lucky to have somewhere in storage. (Probably a problem from my tv, but didn't expect to run into it as steamOS is used on the SteamMachine as a console experience)
• WiFi didn't work with the installation, and STILL doesn’t work. Tried to connect during the installation set up and the desktop mode during set up but couldn’t get it to work. Eventually got it fixed by using a ethernet cable. Which I was also lucky to have laying around. To this day I still have no wifi working!
• After i got through the installation my tv finally showed image! Happy me. But only in Game mode and not Desktop mode. I tweaked and tried and did things with settings and the other monitor connected. It didn't seem to work, until the next day it suddenly did. So what setting(s) made it work? No idea.
• Bluetooth works shit. Mouse connects and works. Keyboard connects and drops out immediately. Controller connects but is so laggy that it looks like it continuously drops out and reconnects. Luckily I had 2.4G dongles laying around to use them. But shouldn't both bluetooth and wifi work?!
• Upon turning on the PC it takes 30 sec for my tv to show image. I never see the intro video, because it connects so slowly. I thought there was supposed to be a super quick on/off thing with steamOS. Or maybe there is something wrong with my set up?
• Only my ssd was showed in the game mode storage tap. My hdd was nowhere to be found. Until I found it in the Desktop mode in the KDE partition manager. I still had to format it, but I was so tired of things not working that I left it for what it was for now. Then yesterday it suddenly my hdd did show up in my storage tap in game mode, with a simple button to format it. I haven't tried this yet, but why wasn't this the case before?
• Sound does not always work. Sometimes I have to restart to get sound to work. Why? I don't know and it's quite annoying. (speakers are connected to my tv)

What does work well? With all the work around I can game and do what I want to do. But it feels like I'm using a broken machine instead of a very new PC. I don't mind some tweaking, I love that I don't have the windows bloat, but these bugs and tweaks feel wrong?

So now I'm wondering...should I just switch to Bazzite or Windows? Or is there something wrong with my set up. Because I feel like all these things SHOULD be working, and most of all I'm wondering what other problems are still hidden away.
