SteamOS 3.5 for Steam Deck gets a screen colour temperature setting

By - | Views: 43,004

A while ago I mentioned (in a video) how the upcoming SteamOS 3.5 for Steam Deck added in a colour vibrance setting, and now Valve seems to have expanded it even further with a screen colour temperature setting as well.

Here's a look at the difference between the default 7500K colour temperature and then turning it up to 11000K, with colour vibrance at default:

You can see the difference very clearly in the second picture where it's turned up, look at the difference in the blues.

This is currently available in the Main + Steam Deck Beta update channels, which you'll see if you turned on Developer Mode, and then select to see the Advanced Update Channels in the Developer menu in settings. I would firmly advise against this though, as it's updated often and can be full of big bugs (there's a reason it's hidden). Stick with the normal Steam Deck Stable / Beta.

SteamOS 3.5 is sounding quite exciting now, hopefully it's not too much longer until it's released.

I switched to Main/Beta due to the instability in the other channels.
The amount of updates is not that big, it's always steam client, but that's the same as other channels.

At least now I can complain about the memory leaks in the clients :-0.

So a switch to 3.5 starts with BIOS updates, and at least 2 dock updates. And my dock needed those updates.

But despite it not having that many OS updates, don't switch if you are not a Linux expert or tinkerer and can not live with a non functioning deck for a while.

For me it was necessary as the dock really had issues with my monitor and I work on the deck. And as a warning: there is a major memory leak in the steam client in desktop mode. It will eat about 6..8GB of memory if you do not open/close/switch views in the next 8..12 hours.
So if you are working and you just have your client in the background for a day, your system will OOM.

To be clear:
these are my current issues:

The memory leak is just bad javascript. The sudden power off issue is not I fear. Got it twice yesterday at a bad spot so I turned off the wifi so I can play divine divinity \0/.

There has been several big issues for people switching branches, with the Steam Deck getting stuck in loops and all sorts. I really do not recommend switching to Main, as said in the article. It's not meant for normal users.

Now if only we can get screen color temperature fixed on nvidia-wayland devices. One of the main thing holding me back from wayland adoption. the glaring blue of the screen hurts my eyes.

wish these sort of features could just be default for wayland de
