Please describe your issue in as much detail as possible:
When unplugging the Steam Deck from a dock that connects it to an external monitor, I expect the primary display to switch back to the Deck's internal screen.
However, since updating to SteamOS 3.6 in the current Preview branch, what happens instead is that the Deck's screen stays off if you disconnect it from an external monitor. There is still sound though.
Putting the Deck to sleep and waking it will not turn the display back on. Only a reboot fixes it.
Conversely, plugging the Deck into a dock while it was on and an image was displayed on it will properly transfer primary display over to a monitor.
This issue is only present in game mode. In desktop mode the display switches without issue. The dock in use here is Valve's Steam Deck Docking Station. The external monitor is connected over Displayport.
After re-imaging the Deck, the issue was not present on the stable branch while the Dock was still on FW 0.13.15.124. It began again after the system was updated to SteamOS 3.6. This seems to point to 3.6 rather than the new Dock firmware as the source of the bug.
Steps for reproducing this issue:
- Connect Steam Deck to a dock and external monitor
- Ensure the Deck is in game mode
- Unplug the USB-C cable to the Deck while an image is being output to the display
