light-locker ============ light-locker is a simple locker (forked from gnome-screensaver) that aims to have simple, sane, secure defaults and be well integrated with the desktop while not carrying any desktop-specific dependencies. It relies on lightdm for locking and unlocking your session via ConsoleKit/UPower or logind/systemd. Requirements ============ To use light-locker with systemd, you need at least lightdm 1.7.0. light-locker doesn't work with lightdm version 1.7.5-1.7.9 Usage ===== After installing light-locker, it will auto start along your session and you will be able to lock your session with "light-locker-command -l". This will redirect you to VT8 (assuming that your open session was on VT7 and is now kept safe by light-locker) and present LightDM's greeter for unlocking your session again. On suspend/resume light-locker will lock the active session and redirect to the LightDM's greeter for unlocking the session again. There is no support for gnome-settings-daemon in order to keep things slim, so you might have to add a custom keyboard-shortcut for this to work. light-locker will automatically lock the session shortly after the X11 screen saver kicks in. The timeout can be set with --lock-after-screensaver. With xset the X11 screen saver can be adjusted. Use --late-locking to avoid some of the negative effects of VT switching. This will lock the session on the deactivation of X11 screen saver instead of activation. light-locker will automatically lock the session on suspend/resume. To disable this behaviour with --no-lock-on-suspend. With --lock-on-lid light-locker will automatically lock the lid close. With logind sessions can have an idle hint. This is used to perform some action after a timeout. Use --idle-hint to let light-locker set the idle hint, in case nothing else does. Building ======== light-locker different configurable dependencies and some of these require the development files to be installed. Most of these configurations will be enabled automatically when their dependencies are available. Here is a list of the different dependencies and there configuration flags: --with-gtk2: This decides between the Gtk+-3.0 and Gtk+-2.0 dependency. --with-systemd: This adds the support for systemd logind. This option requires the development files to be installed. --with-console-kit: This adds the support for ConsoleKit. --with-upower: This adds the support for UPower. --with-mit-ext: This enables the lock-after-screensaver feature. This options requires the X11 Screen Saver extension development files to be installed. --with-dpms-ext: This adds the support for DPMS. This is used to turn on the display on screen saver deactivation. Many of the light-locker features can be disabled/enabled and configured at build time. Here is a list of these configuration flag: --enable-late-locking: Enables --late-locking and --no-late-locking. Default enabled with --no-late-locking. This requires mit-ext. --enable-lock-on-suspend: Enables --lock-on-suspend and --no-lock-on-suspend. Default enabled with --lock-on-suspend. This requires either systemd or upower. --enable-lock-on-lid: Enables --lock-on-lid and --no-lock-on-lid. Default enabled with --no-lock-on-suspend. This requires upower.
