Whether to enable brightness control with keyboard keys.
|
|
|
|
This is mainly useful for minimalistic (desktop) environments. You
|
|
may want to leave this disabled if you run a feature-rich desktop
|
|
environment such as KDE, GNOME or Xfce as those handle the
|
|
brightness keys themselves. However, enabling brightness control
|
|
with this setting makes the control independent of X, so the keys
|
|
work in non-graphical ttys, so you might want to consider using this
|
|
instead of the default offered by the desktop environment.
|
|
|
|
Enabling this will turn on {option}`services.actkbd`.
