Customize Chromebook Chrosh Shell Environment

Requirement: Chromebook, Common Sense, Commandline Ablity, 1 hour of time

Dear developers with a spare Chromebook lets inject a little personalization into your Crosh shell with custom fonts, the solarized theme, and extra secure shell options.

Also, keep in mind that the terms Chrosh, Chrosh Window, and Secure Shell all refer to various versions and extentions built around the ChromeOS terminal. Settings that affect the ChromeOS terminal are global.

Custom Fonts

Setup vagrant vm

vagrant box add precise64 http://files.vagrantup.com/precise64.box
vagrant init precise64
sed -i 's/# config.vm.network :hostonly/config.vm.network :hostonly/' Vagrantfile
vagrant up
vagrant ssh

Install base software and apache (to have something to proxy)

Mouse and Keyboard power off

Do you use an usb mouse and keyboard and have laptop_mode installed under your Arch linux ? Then maybe you have the same problems as me - mouse and keyboard getting inactive every 2 seconds or so.

To solve this, go to /etc/laptop-mode/conf.d and copy usb-autosuspend.conf to /etc/laptop-mode/conf.d/board-specific. After that run lsusb and get the ID of the usb device you want, e.g., 093a:2500 .

Open the board-specific/usb-autosuspend.conf file and find the AUTOSUSPEND_USBID_BLACKLIST conf option. Put the desired usb IDs there. You might need to run sudo laptop_mode afterwards to reload the configs.

	# - You can set a password for root accounts.
	# - You can remove root accounts that are accessible from outside the local host.
	# - You can remove anonymous-user accounts.
	# - You can remove the test database (which by default can be accessed by all users, even anonymous users),
	# and privileges that permit anyone to access databases with names that start with test_.
