Before, we introduced you Redshift GUI to reduce your screen brightness. Reducing screen brightness may save your eyes and may prolong your laptop battery duration. But you need to install something if you want to do that. What if you want to reduce brightness without installing any program? Use built-in xrandr command.
Reducing into Half
xrandr --output LVDS1 --brightness 0.5
Reduce into Very Low
xrandr --output LVDS1 --brightness 0.1
Back To Normal
xrandr --output LVDS1 --brightness 1
xrandr --output LVDS1 --brightness 2
Knowing Your Output
If the command above fails, probably your output screen LVDS1 is incorrect. LVDS1 is used in laptop. You should know your output screen whether it is LVDS1 or else. Use this command
See the output. Look for the connected line. Ignore the disconnected lines. In this example, my correct output is LVDS1. In other hand, DP1, HDMI1, VGA1, and VIRTUAL1 are not my output. See picture above.

You can use KSuperkey in Linux if you prefer to open menu by single Windows Key (Linux says "Super Key"). KSuperkey is a hack created by Hanschen in 2012. KSuperkey allows you to open and close KDE menu by just a single button (Super Key) like in Windows. I will show you how to do that in Kubuntu.
I have a Windows-user habits even if I use Linux now. One of them is sorting files by type and show them in groups in file manager. The file manager I know capable for it is Dolphin. Dolphin is KDE file manager. It is included by default in Kubuntu. I will show you how to achieve it easily and how to change by a single click.
