First successful PIN entry at startup ignored

Your system information

• Device: Steam Deck LCD
• Steam client version: 1768615943
• SteamOS version: 3.7.20 (build 20260108.1)
• Opted into Steam client beta?: Yes
• Opted into SteamOS beta?: Yes -- issue present in both stable and beta channels for the last few weeks
• Have you checked for updates in Settings > System?: Yes

Please describe your issue in as much detail as possible:

On Steam Deck startup, successfully entering the PIN blanks the input (filled bullets become hollow again) without any error message, requiring it to be submitted a second time. Entering it a second time unlocks the device as normal.

No error is shown on the first success, unlike an incorrect attempt which correctly shows a warning as normal. Entering the PIN successfully after an incorrect attempt still resets the screen.

Resuming from sleep doesn't require a second PIN entry. Switching from Desktop Mode back to Gaming Mode does require a second entry.

Steps for reproducing this issue:

1. Boot, reboot, or switch to Gaming Mode
2. Enter PIN successfully
   • PIN screen continues to show, input reset
3. Enter PIN successfully again
   • UI progresses to Loading user data... / home screen

This fixed it for me:

The settings ‘On system wake and power up’ and ‘Before showing login screen’ get in each other's way. When turning the before showing login screen off, the issue has been solved for me. Your deck is still safe because the system wake setting is still on

Thanks for the tip, good find! Indeed I had both of those options enabled, and disabling Before showing login screen covers all the cases exactly once.

Bit odd that these two options are applied on top of each other -- it would probably make more sense to just have wake (i.e. resume from standby) and power up (i.e. login session start, which includes switching from Desktop Mode) be the two options.

Yeah, there are quite a few quirks with the OS that could be done better. Finding workarounds for everything is pretty time consuming.
