- The files in this archive provide a method for darkening the NeXT display
- completely when logging out. This prevents burn-in of the login dialogue
- box. This technique has been tested under NeXTStep 1.0 and 2.0.
-
- To use the technique, follow these steps.
-
- 1. Pick a place to install the VidLev program and the LoginHook and
- LogoutHook shell scripts. If you don't want to use /usr/local/etc,
- modify the BIN string in Makefile to identify the installation path.
- Make sure that the BIN path exists.
-
- 2. Become root and:
-
- # make install
-
- The install rule will compile VidLev, customize the LoginHook and
- LogoutHook shell scripts, install all three, and set root's defaults
- for the loginwindow program's login and logout hooks.
-
- 3. Reboot. (This makes loginwindow aware of the login and logout hooks.)
-
- When you log out the screen will darken completely. You can rebrighten it
- by pressing the "brightness up" key on the NeXT keyboard (next to the
- "Power" key) -- moving the mouse or typing a login and password to the login
- dialogue box will not restore brightness until after the loginwindow manager
- has attempted to dim the login dialogue box (about 30 minutes after logoff).
- VidLev will darken the screen again every 10 minutes until someone logs on,
- so that loginwindow's post-logoff dimming won't accidentally raise the video
- level from VidLev's complete darkness to a dim login dialogue box level. At
- login the LoginHook script sends a SIGHUP to the VidLev process and it
- restores screen brightness values to ones remembered from logout time.
