By - | Views: 27,999

Valve has now released the latest SteamOS 3.5.1 Preview for download, fixing up some more issues in the Steam Deck OS like the backlight staying on when docked.

To update to this version you need to be in the Preview branch of SteamOS updates via Settings > System > System Update Channel. Like shown in the below picture:

The full update notes are below:

General
  • Fixed a case where an SD card with filesystem errors would be mounted as read-only.
  • Fixed the custom performance overlay presets file inheriting the default settings from the steam presets.
  • Fixed internal display rotation being erroneously reported to the game.
Firmware 118
  • Actually added undervolting controls.
External display
  • Fixed a 3.5 regression with HDMI output.
  • Fixed a long-standing issue where the internal display backlight would always stay on.
  • Fixed bug with HDR applications showing in wrong colorspace if they moved their window during swapchain creation.
  • Fixed HDR not working in 32-bit applications.
  • Added HDR Analysis to developer settings.
  • Disabled HDR exposure in "My Little Pony: A Maretime Bay Adventure" as it enables it without rendering in HDR.
Desktop Mode
  • Fixed a case where the desktop could be empty and apps would fail to launch.
  • Fixed a bug where switching to the Plasma Desktop transition could result in broken colors.

Good to see! I've encountered this one and it gave a poor first impression of desktop-mode.

In before anyone acts like this is an odd choice to devote dev-time to - if this endeavour is to succeed like consoles do, then Valve needs to hook the family market.

I'm as unbrony as you can be, and have never even seen any of the show. But even I plan on getting the My Little Pony pinball table on the new Pinball FX game. XD

Also, John de Lancie is cool, and he voiced one of the characters on the show and also the documentary about bronies. lol
