"""Shows a widget for each connected screen and allows the user to enable/disable screens.
|
|
|
|
Parameters:
|
|
* xrandr.overwrite_i3config: If set to 'true', this module assembles a new i3 config
|
|
every time a screen is enabled or disabled by taking the file "~/.config/i3/config.template"
|
|
and appending a file "~/.config/i3/config.<screen name>" for every screen.
|
|
* xrandr.autoupdate: If set to 'false', does *not* invoke xrandr automatically. Instead, the
|
|
module will only refresh when displays are enabled or disabled (defaults to false)
|
|
|
|
Requires the following python module:
|
|
* (optional) i3 - if present, the need for updating the widget list is auto-detected
|
|
|
|
Requires the following executable:
|
|
* xrandr
