Valve pauses Steam Deck hibernation in its latest SteamOS beta
Valve has temporarily disabled hibernation on Steam Deck in the latest SteamOS beta because of unresolved driver bugs. SteamOS 3.9.4 also fixes several problems introduced during testing, including games running behind the loading screen and screenshots being limited to 720p.

This is a Beta and Preview channel update, not a new stable release for every Steam Deck owner. Hibernation remains experimental, and Valve has not given a date for restoring it on the handheld.

Hibernation support was introduced as a preliminary developer feature during the SteamOS 3.9 testing cycle. It is not yet exposed through the Game Mode interface. The new release improves that work more broadly while explicitly switching it off on Steam Deck devices.

The change should therefore not be read as Valve removing the handheld's ordinary suspend function. The release notes identify hibernation specifically, rather than announcing the end of the familiar sleep-and-resume behaviour.
There are also improvements to experimental dirlock disk encryption. Neither addition turns these developer options into finished consumer features.

Games and Desktop Mode receive fixes for visible beta regressions
One bug could prevent a switch to Desktop Mode after changing the time zone until the system was rebooted. Valve says 3.9.4 fixes it.
Another regression left some applications, including A Plague Tale: Innocence, running behind Steam's loading screen. A separate correction allows screenshots to retain higher resolutions instead of being captured at 720p despite the game and display running above that.
Steam Machine also gets a fix for firmware updates occasionally failing to apply. Valve has reduced audio clicks from the 3.5mm output with sensitive headphones or speakers.
These changes build on the earlier SteamOS 3.9.3 preview. Owners already testing the branch can find update-channel controls under Settings, System, System Update Channel.
