A fresh SteamOS host install failed on-glass two ways: KWin denied Desktop-mode capture (zkde_screencast_unstable_v1) so every session died in the pipeline build, and the native Steam Deck pad degraded to an Xbox 360 controller. Both stem from setup that only a fresh login applies — the host user-service keeps the pre-install group set and KWin reads its .desktop grant at session start — plus a missing vhci-hcd autoload the pad's USB/IP transport needs (the deb/rpm/arch packages ship it; the Deck installer did not). - install.sh: install punktfunk-modules.conf (+ modprobe vhci-hcd now) for the native Deck controller transport, seed the KDE RemoteDesktop grant (kde-authorized) for Desktop-mode input, and print a loud "reboot before streaming" notice when a relogin is actually required (input group added or the .desktop grant first installed). - update.sh: retrofit the udev rule, vhci-hcd autoload, input group, and grant so existing installs pick them up on the next update without a reinstall. - steamos-host.md: document the first-install reboot and the native controller passthrough requirements (input group + vhci-hcd + client-side Steam Input Off).
