![]() ![]() fade_brightness ( 75, start = 25 ) #fade the brightness from the current value to 100% in steps of 10% sbc. fade_brightness ( 50 ) #fade the brightness from 25% to 75% sbc. Usage: import screen_brightness_control as sbc #fade brightness from the current brightness to 50% sbc. blocking - If set to False it fades the brightness in a new thread.increment - The amount to change the brightness by each step in percent.interval - The time interval between each step in brightness.If not specified it defaults to the current brightness finish - The brightness value to fade to.Otherwise it returns the list of thread objects that the process is running in If it runs in the main thread it will return the final brightness upon success, ScreenBrightnessError upon failure. set_brightness ( 50, display = 0 ) fade_brightness( finish, start=None, interval=0.01, increment=1, blocking=True, **kwargs)įades the brightness from start to finish in steps of increment, pausing for interval seconds between each step. set_brightness ( '-30' ) #set the brightness of display 0 to 50% sbc. set_brightness ( '+25' ) #decrease brightness by 30% sbc. set_brightness ( 0, force = True ) #increase brightness by 25% sbc. set_brightness ( 50 ) #set brightness to 0% sbc. Usage: import screen_brightness_control as sbc #set brightness to 50% sbc. In the future this function will return None by default. By default, the return value is the new brightness value but this behaviour is deprecated. no_return - boolean value, whether this function should return None or not. ![]() If set to True then it will bypass this check ![]() force (Linux only) - if set to False then the brightness is never set to less than 1 because on Linux this often turns the screen off.value - the level to set the brightness to.If value is a string and contains "+" or "-" then that value is added to/subtracted from the current brightness. get_brightness ( display = 'BenQ GL2450H' ) set_brightness( value, display=None, method=None, force=False, verbose_error=False, no_return=False) get_brightness ( display = 1 ) # get the brightness for a named monitor benq_brightness = sbc. get_brightness ( display = 0 ) # get the brightness of the secondary display (if connected) secondary_display_brightness = sbc. get_brightness () # get the brightness of the primary display primary_display_brightness = sbc. Usage: import screen_brightness_control as sbc # get the current screen brightness (for all detected displays) all_screens_brightness = sbc. verbose_error - a boolean value to control how much detail any error messages should contain.On Windows this can be 'wmi' or 'vcp' and on Linux this can be 'light', 'xrandr', 'ddcutil', 'sysfiles' or 'xbacklight' method - the OS specific method to use.This can be an integer or a string (EDID, serial, name or model) display - the specific display you wish to adjust.Raises ScreenBrightnessError upon failure It may return a list of values if you have multiple, brightness adjustable monitors. Returns the current screen brightness as a percentage. get_brightness( display=None, method=None, verbose_error=False) You can read the full documentation for this project for more details but here are the basics. > -v, -verbose some messages will be more detailed > -m METHOD, -method METHOD specify which method to use > -f VALUE, -fade VALUE fade the brightness to this value > -g, -get get the current screen brightness > -s VALUE, -set VALUE set the brightness to this value > -d DISPLAY, -display DISPLAY the display to be used > -h, -help show this help message and exit python -m screen_brightness_control -help You can call this module from your command line or use it as a python library (see the documentation section below). Something to be aware of is that xrandr does not change the backlight of the display, it just changes the brightness by applying a filter to the pixels to make them look dimmer/brighter. Here is a quick outline of each program: Program If you do not wish to install any 3rd party programs you will have to run this module as root. Pip3 install screen-brightness-control GitHub: git clone įor running on Linux you may need to install one of these programs: xrandr, ddcutil, light or xbacklight. Supports Windows and most flavours of Linux. A Python tool for controlling the brightness of your monitor.
