# All flags are PS5-specific workarounds:
#   LIBSEAT_BACKEND=logind   : avoids seatd/logind conflict; matches the user
#                              session so gamescope can take DRM/input devices
#                              via logind TakeDevice()
#   WLR_LIBINPUT_NO_DEVICES=1: suppresses libinput "no input devices" abort;
#                              PS5 has no directly-attached HID devices on boot
#   --backend drm            : take the DRM device directly (no nested compositor)
#   -e                       : embedded / Steam Big Picture mode
#   --prefer-output DP-1     : target the PS5's internal DP connector
#   --sdr-gamut-wideness 0   : keep SDR colour space at sRGB; the PS5's internal
#                              DP->HDMI bridge cannot translate BT2020 signalling
#
# The ps5-display.lua script in ~/.config/gamescope/scripts/ enforces sRGB
# colorimetry at the DRM atomic commit level (belt-and-suspenders with the flag).
