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.

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

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.
