+- **fix: on an NVIDIA PC that had single user mode on before the SteamOS conversion, "Return to Gaming Mode" and the boot choice work again: single user mode's desktop autologin (`zzz-steamify-autologin.conf`, read last) pinned the Plasma session; the conversion removes it, and turning the conversion off sets it up again**
+
 - **fix: when an option fails, its sub-options are not applied any more (a failed conversion used to leave its "Boot into the desktop", silent start and icons on without it)**
 
 - **fix: a PC that keeps `python-hidapi` (liquidctl needs it) can use the SteamOS conversion: jupiter-hw-support, which gamescope-session-cachyos depends on, wants `python-hid`, which conflicts with it and stopped the package install. Steamify builds and installs an empty placeholder package that provides `python-hid` first (`patches/python-hid-shim.PKGBUILD`); only the Steam Deck controller firmware updater uses it**
