How to Permanently Save Screen Brightness in Fedora 16

For Fedora 15, there is an entry in dconf-editor that will do the trick (system setting GUI can never do it permanently, shame on it). But in Fedora 16 that entry is no longer there. After googling there seem to be 2 possible solutions.


  1. Change the value in /sys/class/backlight/acpi_video0/brightness each time OS boots.
    1. Create /etc/rc.d/rc.local (Fedora no longer ships it since release 16).
    2. Edit the file so that it looks like this.
    3. $ cat /etc/rc.d/rc.local
      #!/bin/bash
      echo 7 > /sys/class/backlight/acpi_video0/brightness
    4. Make /etc/rc.d/rc.local executable.
    5. $ sudo chmod a+x /etc/rc.d/rc.local
  2. Add kernel parameter (to be investigated).

How to Adjust Fonts Rendering in Fedora 16

I've heard some voice about how lame fonts rendering is in Fedora 15 & 16. For me, it does look weird on my desktop, but fine on my laptop. Anyway, I'll put the instruction link here because it's a good one. And after I did all the settings mentioned in that document English fonts look thinner in terminal but everything else, especially Chinese characters look better.
