From c28643ce5bc8c7fd825e4eabbd915bad2b91dbd0 Mon Sep 17 00:00:00 2001 From: Aaron Marcher Date: Sun, 27 May 2018 16:46:03 +0200 Subject: Revert "Add basic backlight percentage support" On OpenBSD the backlight percentage cannot be retrieved in a simple way. The only two solutions we are aware of for now are: - reading from /dev/ttyC0: which isn't possible without changing permissions or running slstatus as root - linking against xcb-xrandr: which is bloat and does not work in every case appearently This reverts commit 37724ac2c3f496f4736223d0d8e5d8fecb933590 for now. --- components/backlight.c | 32 -------------------------------- 1 file changed, 32 deletions(-) delete mode 100644 components/backlight.c (limited to 'components/backlight.c') diff --git a/components/backlight.c b/components/backlight.c deleted file mode 100644 index f9c4096..0000000 --- a/components/backlight.c +++ /dev/null @@ -1,32 +0,0 @@ -/* See LICENSE file for copyright and license details. */ -#include "../util.h" - -#if defined(__linux__) - #include - - #define BRIGHTNESS_MAX "/sys/class/backlight/%s/max_brightness" - #define BRIGHTNESS_CUR "/sys/class/backlight/%s/brightness" - - const char * - backlight_perc(const char *card) - { - char path[PATH_MAX]; - int max, cur; - - if (esnprintf(path, sizeof (path), BRIGHTNESS_MAX, card) < 0 || - pscanf(path, "%d", &max) != 1) { - return NULL; - } - - if (esnprintf(path, sizeof (path), BRIGHTNESS_CUR, card) < 0 || - pscanf(path, "%d", &cur) != 1) { - return NULL; - } - - if (max == 0) { - return NULL; - } - - return bprintf("%d", cur * 100 / max); - } -#endif -- cgit v1.2.3
