# Steamify: gamescope-session starts gamescope without a size or a refresh rate, so it takes the display's *preferred* mode,
|
|
# which many monitors declare as 60 Hz (the faster modes sit in an extension block of the EDID). This starts it the way the
|
|
# desktop runs that display: the mode KDE has saved for the connected display (System Settings > Display), when the display
|
|
# still has it, else its biggest mode at the highest refresh rate.
|
|
# Read at every session start (modetest, part of libdrm which gamescope needs, and KDE's ~/.config/kwinoutputconfig.json), so
|
|
# changing the resolution in KDE, another monitor or a TV just works. Anything unclear (no modetest output, no modes, more than
|
|
# one display connected: gamescope chooses which one it uses) leaves gamescope's own choice alone.
