  • [SCRIPT] Modifying Display Scale

    First off sorry if this doesnt warrent its own thread,

    I wrote a script for managing a displays scale, and to fix under/over scan with different displays on rk3188 deivces (possibly rk3066 devices?) by modifying fb0's scale

    heres a link to it https://www.dropbox.com/s/or01bztx4patw71/fb-scale.sh

    You should run it with "sudo bash fb-scale.sh"
    Hope it helps someone.

    Cheers

      You need to modify rc.local as root user, so run sudo gedit /etc/rc.local (if necessary replace gedit with the text editor picuntu uses)

        Amazing!

        I think this script should be a part of all the Images available online. It worked flawlessly. 95% was spot-on with my screen size. One more question, how do I make the changes permanent cause it seems the screen comes back to "oversize" when I reboot the Dongle.

          Hi, glad it works for you, so to enable this at boot, you can use the /etc/rc.local file (i wrote that script very quickly, didn't have time to enable it at boot)

          You can add:

          Code:
          echo "$scale $scale" > /sys/devices/platform/rk-fb/graphics/fb0/scale
          (replacing $scale with the value that works for you.) to /etc/rc.local (before "exit0") and it should enable at boot. Or just use your Desktop environments "Startup applications" and add the above command.

          Cheers

                It doesn't work for me. I try it in my t428 with ubuntu 12.04 but nothing changes. The script changes the values in the scale file but monitor does not scale.
                I can't solve overscan problem with linux image on sd card and my damned asus 24T1e monitor...
