Kill the trackpad!

Some people really hate the Cr-48's trackpad. Even if you plug a USB mouse into it, the slightest brush of a finger across the pad is enough to move your cursor position and suddenly you're off typing somewhere you didn't mean to be. So I've found a way to kill the trackpad (software only, no hardware mods needed):

Standard Disclaimer: Making these changes may cause issues on your Cr-48. I'm not responsible for problems you may have as a result of running these commands (though they do work fine on my machine). If you run into problems, you may need to recover using Google's USB Recovery method.

  1. Get root (otherwise known as developer mode)
  2. You need read/write access to the / partition:
    /usr/share/vboot/bin/make_dev_ssd --remove_rootfs_verification
  3. reboot the Cr-48:
    reboot
  4. now back at the root prompt, run one more command. qemacs is a text editor and xorg.conf is the X11 configuration file that we need to modify
    qemacs /etc/X11/xorg.conf
  5. Scroll down to the line that says Driver     "syntp". Change syntp to just mouse (leave quotes as is).
  6. Hit CTRL+X on the keyboard, then CTRL+C, you'll be asked if you want to save the file, hit Y.
  7. Reboot, the trackpad should be dead!!!
