PHOC.INI() PHOC.INI()

phoc.ini - Configuration file for phoc

Most of phoc's configuration is read from GSettings. Output and core settings are read from phoc.ini. The configuration file is searched in phoc's current working directory. It's path can also be given on the command line via the -C option.

The phoc.ini file is composed of multiple sections which can be in any order. If values are not given then built in defaults are used. The main purpose of phoc.ini is to specify output configuration and layouts. Each section has the form:

[SectionHeader]
key1 = value1
key2 = value2


Lines starting with # are considered comments and are ignored. The section headers might contain a colon in which case the part after the colon specifies the configuration item e.g.

[output:DSI-1]


is the configuration section for the output DSI-1.

The available section headers are:

  • core: core options
  • output: output configuration

Modifications to this file require a compositor restart to take effect.

The core section can appear only once and has a single option:

•
xwayland=[true|immediate|false]: Whether to enable XWayland. With true XWayland is activated when, needed. immediate launches it immediately and false turns it off.

The output section can appear multiple times with different configuration items

[output:ITEM]


ITEM is either the DRM connector name like DSI-1 or DP-2 or the make, model and serial as obtained from EDID separated by %: [output:A Vendor%The Model%Serial]. Make, model and serial can be specified as * to match any value. The configuration options are:

  • enable=[true|false]: Whether the output should be enabled
  • x, y: The x and y position in the output layout. This can be used to arrange outputs. The default is to use automatic layout (new outputs are added to the right of the current layout).
  • scale: The outputs scale. The default auto calculates the scale based on the screen size.
  • rotate: The rotation. Valid values are normal, 90, 180, 270, flipped, flipped-90, flipped-180 and flipped-270. The default is to use normal orientation.
  • mode: The mode to use. The mode must be a valid mode for this output. See e.g. the output of wlr-randr. The default is to use the outputs preferred mode.
  • modeline: A custom video mode. This is only valid for the DRM backend
  • scale-filter: Filter to use to scale down textures. Valid values are bilinear, nearest and auto. The later selects bilinear for fractional and nearest for integer scales automatically. If unset auto is assumed.
  • drm-panel-orientation: If true applies the panel orientation read from the DRM connector (if available). Defaults to true.
  • phys_width, phys_height: The physical dimensions of the display in mm.

Example:

[output:DSI-1]
scale = 2
[output:Some Vendor%Some Model%*]
scale = 1
rotate = 90
x = 300
