Do you want to decrease your screen brightness? Have tried all the ways but failed? Use RedshiftGUI to dim your screen. I always recommend RedshiftGUI to Indonesian Linux users as a "final combo" when installing graphics driver or upgrading Linux kernel brings nothing to their screen brightness. I will show you the steps to install, dim screen, and set RedshiftGUI to Ubuntu startup.

  3. Download into your Home folder. 
  4. Put The DEB Package in Your Home Folder
  5. Open Terminal.

  7. Press TAB button. So, Terminal completes the command automatically into sudo dpkg -i RedshiftGUI-0.2.1-Linux-i686.deb
