From 472a4993b0e6780a44e2970b8b02df83a07e736d Mon Sep 17 00:00:00 2001 From: Nick Sayer Date: Sat, 2 Oct 1999 03:56:42 +0000 Subject: [PATCH] Add the apm_saver syscons screen saver module. apm_saver uses the apm_display() routine from the apm system to "suspend" the "display" part of the machine. This is beneficial for some laptops (or other machines with non-traditional displays) that choke on the 'green' saver's effect. Another way of looking at this is that it's the same as a screen saver that does an 'apm -d 0' to blank the display and an 'apm -d 1' to bring it back. One probably ought to use these commands to make sure the effect will be correct before using it unattended. --- sys/dev/syscons/apm/apm_saver.c | 91 +++++++++++++++++++++++++++++ sys/modules/syscons/Makefile | 1 + sys/modules/syscons/apm/Makefile | 9 +++ sys/modules/syscons/apm/apm_saver.c | 91 +++++++++++++++++++++++++++++ 4 files changed, 192 insertions(+) create mode 100644 sys/dev/syscons/apm/apm_saver.c create mode 100644 sys/modules/syscons/apm/Makefile create mode 100644 sys/modules/syscons/apm/apm_saver.c diff --git a/sys/dev/syscons/apm/apm_saver.c b/sys/dev/syscons/apm/apm_saver.c new file mode 100644 index 00000000000..d7863ba9a53 --- /dev/null +++ b/sys/dev/syscons/apm/apm_saver.c @@ -0,0 +1,91 @@ +/*- + * Copyright (c) 1999 Nick Sayer (who stole shamelessly from blank_saver) + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
