Chromebook Cookbook

Developer Mode

  1. Power down the Chromebook
  2. Hold down the <esc-refresh> buttons and press the power button.
  3. When you see the screen backlighting come on, release <esc-refresh> and select <ctrl-d>.
  4. At the scary developer mode screen, click <ctrl-d>.
  5. It will erase the current install image, and switch to developer mode – it takes about 6 minutes and a few reboots.
  6. After bootup, go to VT2 and set the root password.

Misc Handy Tools

Hard Drive Speed (SDCard/USB)  : ‘sudo hdparm -Tt /dev/sda’

Interesting Key Mappings

  • Ctrl-Alt-Shift-F3 Spins Display
  • Ctrl-Alt-F1 VT1 terminal / the default Chromebook screen
  • Ctrl-Alt-F2 VT2 terminal / the Chromebook terminal interface
  • Ctrl-Alt-F3 VT3 terminal / the Crouton interface (if installed)
  • Ctrl-Alt-/ Onscreen Key Map

Function Key Mappings

  • There is no delete key
  • Left Arrow = F1 (VT1)
  • Right Arrow = F2 (VT2)
  • Refresh = F3 (VT3)
  • Fullscreen = F4
  • External Display = F5
  • Dimmer = F6
  • Brighter = F7
  • Mute = F8 (VT8)
  • Vol- = F9
  • Vol+ = F10

VT Controls

  • VT1 is the main Chrome screen, VT2 is a terminal, and VT3 is a CLI (command line interface) mapped to a crouton chroot.
    • If you have a crouton CLI running:
      • From VT1, you switch to VT2 with ctrl-alt-F2, but you cannot switch to VT3 since F3 is mapped to refresh.
      • From VT2, you can switch to VT1 with ctrl-alt-F1, and you can switch to VT3 with ctrl-alt-f3.
      • From VT3, you can switch to VT1 with ctrl-alt-F1, and you can switch to VT2 with ctrl-alt-f2.

    Great Work here, pulling all those informations together!
    If you’re still keeping this site up to date, you might also want to add how to expand you’re RAM (via Swap).
    You simply go into the shell and type ‘swap enable 2000’, and reboot.
    The doubled RAM did the trick for my HP Chromebook 11, which was pretty slow before that. As the eMMC is pretty fast, some virtual RAM should a pretty standard solution, especially when you’re working in Chrome with only 2 GB (I still don’t get it why they made this a standard)
    Btw, theres no need for Dev Mode or anything, just go ahead an try it 😉
