PortProtonQt session

This project is not affiliated with Valve (wide inspiration was taken from their work on the SteamDeck)

Basic manual setup

Copy this repository file structure into the appropriate places and you'll be able to start the session on any Display Manager of your choice.

User Configuration

The session sources environment from ~/.config/environment.d/*.conf files. The easiest way to configure the session is to create ~/.config/environment.d/gamescope-session-plus.conf and set variables there:

# Size of the screen. If not set gamescope will detect native resolution from drm.
SCREEN_HEIGHT=2160
SCREEN_WIDTH=3840

# Internal render size of the screen. If not set, will be the same as SCREEN_HEIGHT and SCREEN_WIDTH.
INTERNAL_WIDTH=1280
INTERNAL_HEIGHT=800

# Orientation adjustment of panel, possible values: left, right
ORIENTATION=left

# Enable VRR
ADAPTIVE_SYNC=1

# Treat the internal panel as an external monitor
PANEL_TYPE=external

# Set priority of display connectors
OUTPUT_CONNECTOR='*,DSI-1'

# Set the specific values allowed for refresh rates
CUSTOM_REFRESH_RATES=40,50,60

# DRM mode generation algorithm (cvt, fixed)
# TODO: what is this ?
DRM_MODE=fixed
