![]() Notification and Notification Area Guidelines. ![]() This topic contains the following sections: The notification area has been known historically as the system tray or status area. It can also be used to display icons for system and program features that have no presence on the desktop, such as battery level, volume control, and network status. Thus, through using dbus we actually control the hardware.The notification area is a portion of the taskbar that provides a temporary source for notifications and status. This answer relies on the dbus interface, which alters the actual brightness setting, represented by a file in /sys/class/backlight's sub-folder. Only modification, if your hardware has support to actually change theīrightness, you will probably prefer to use xbacklight. ![]() Usefulįor overly bright or overly dim outputs. Multiply the gamma values on the crtc currently attached to the output to specified floating value. PCT="$(zenity -scale -text='Choose brightness level')"Īdditional Info: While many answers here rely on xrandr, it's worth to note that xrandr is not an "actual" hardware solution, i.e., it may change colouring of the screen such that it appears less bright, but the actual power consumption from the screen does not decrease.

If you don't have $HOME/bin directory, create one.You can bind it to keyboard shortcut, or desktop, or launcher. At this point script is ready to work.Open terminal, navigate to the script location.Preferably it would be in $HOME/bin folder. Open gedit text editor, copy over the code, save the file.The script can be copied from here, or imported from my github. Knowing that Ubuntu's Unity relies on dbus service to communicate many settings and events to kernel and hardware, I've put together a simple bash script that relies on dbus and zenity -scale. In the Exec= line, the assumption is that the script is in $PATH (which includes ~/bin on Ubuntu), and executableĬustom brightness controls script using dbus and zenity scale.Yopu can choose your own icon, or save the icon below as set_brightness.png: In the Icon= line, set the path to the icon. ![]() desktop file in ~/.local/share/applications To make a nice set, you could make the slider available in Dash, the Launcher or any other application menu, by adding a. Click the "+" and add the command: brightness_set Make it executableĪdd it to a shortcut key: Choose: System Settings > "Keyboard" > "Shortcuts" > "Custom Shortcuts". Paste the script into an empty file, save it as brightness_set in ~/bin (you probably have to create the directory). # if everything ok, invoke UI and start Gtk thread loop NewBrightness = float(_value())/100Ĭmd = "xrandr -output %s -brightness %.2f" % (self.monitor, newBrightness)ĬmdStatus = subprocess.check_output(cmd, shell=True) Monitor = subprocess.check_output("xrandr -q | grep ' connected' | cut -d ' ' -f1", shell=True)ĬurrB = subprocess.check_output("xrandr -verbose | grep -i brightness | cut -f2 -d ' '", shell=True) If(self.monitor = "" or self.currB = ""): "Unable to detect active monitor, run 'xrandr -verbose' on command-line for more info") Key, modifier = Gtk.accelerator_parse('Escape')Īnnect(key, modifier,, Gtk.main_quit) nnect("destroy", lambda w: Gtk.main_quit()) Self.adjustment = Gtk.Adjustment(self.currB, 0, 100, 1, 10, 0) # get active monitor and current brightness I am using it ever since on my netbook, running Xubuntu and it seems to run on anything.įor reasons of not posting a link-only answer, here it is: #!/usr/bin/env python ![]() On this site, a while ago I found an nice script from someone. ![]()
