# Launch Steam Big Picture and force it fullscreen on headless X11
|
|
#
|
|
# On headless servers with an HDMI dummy plug, Steam Big Picture frequently
|
|
# renders as a 1280x800 window instead of going fullscreen. This means
|
|
# Sunshine captures the entire root window (3840x2160) and Moonlight shows
|
|
# mostly desktop background — user sees a "black screen."
|
|
#
|
|
# Additionally, the dummy plug enters DPMS Off after ~15 minutes of
|
|
# inactivity, causing X11 capture to return black frames. This script
|
|
# forces the display on before launching Steam.
|
|
#
|
|
# Deploy to ~/.config/sunshine/scripts/steam-bigpicture.sh
|
|
# Reference in apps.json:
|
|
# "detached": ["/home/ray/.config/sunshine/scripts/steam-bigpicture.sh"]
|
|
# Also add DPMS fix to prep-cmd (Sunshine runs commands directly, use sh -c):
|
|
# "do": "sh -c 'DISPLAY=:0 xset -dpms s off; DISPLAY=:0 xset dpms force on'"
