Howto Install Linux on Chromebook

Suggest: ‘Linux on Chromebook how to’ LAS episode

The Acer C720 Chromebook (and newer Chromebooks in general) features a “legacy boot” mode that makes it easy to boot Linux and other operating systems. The legacy boot mode is provided by the SeaBIOS payload of coreboot. SeaBIOS behaves like a traditional BIOS that boots into the MBR of a disk, and from there into your standard bootloaders like Syslinux and GRUB.

Accessing the superuser shell with Chrome OS installed

If you have configured Chrome OS already:

  • Open a crosh window with Ctrl + Alt + T.
  • Open a bash shell with the shell command.
  • Become superuser with sudo bash

Enabling the pre-installed version of SeaBIOS

This method will allow you to access the pre-installed version of SeaBIOS through the Developer Mode screen in coreboot.

  • Inside your superuser shell enter:

    crossystem dev_boot_usb=1 dev_boot_legacy=1

  • Reboot the machine.

You can now start SeaBIOS by pressing Ctrl + L at the white boot splash screen.

Remove the write-protect screw to Perma-Disable the boot message warning

By removing the bottom panel of the laptop by removing the 12 visible screws and another one underneath the warranty sticker, then separating the plastic starting at the back

Finally completely remove the write-protect screw from the motherboard, which is labelled as #7 in this picture

ChromeeOS will install elementary OS (with ChrUbuntu) and apply automatically all the necessary fixes to run elementary OS on Chromebooks. You will be able to boot in ChromeOS or elementary OS on your Chromebook.


Legacy Boot Doesn’t Work

Sometimes it’s possible to break the SeaBIOS install in the flash (sometimes doing innocuous things like tweaking the GBB flags). If you do get into such a situation:

  • Check that dev_boot_legacy is set to 1 when you run crossystem
    • If it isn’t, then see the normal Legacy Boot section above
    • if it is, then see below
You can safely reset the copy of SeaBIOS in your flash by running (as root):

# chromeos-firmwareupdate --sb_extract /tmp
# flashrom -w /tmp/bios.bin -i RW_LEGACY

OwnCloud 7 Digital Ocean Tutorial?

For xUbuntu 14.04 run the following:

sudo sh -c "echo 'deb http://download.opensuse.org/repositories/isv:/ownCloud:/community/xUbuntu_14.04/ /' >> /etc/apt/sources.list.d/owncloud.list"

sudo apt-get update
sudo apt-get install owncloud

You can add the repository key to apt. Keep in mind that the owner of the key may distribute updates, packages and repositories that your system will trust (more information). To add the key, run:

wget http://download.opensuse.org/repositories/isv:ownCloud:community/xUbuntu_14.04/Release.key
sudo apt-key add - < Release.key  

Navigate to your ownCloud instance.

  • If you are installing ownCloud on the same machine as you are accessing the
    install wizard from, the url will be https://localhost/owncloud

Which is better files synchronizer – ownCloud or BitTorrent Sync?

BitTorrent Sync

Share directly from device to device. No cloud. No limits.


Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it’s transmitted
over the Internet.

  • Private. None of your data is ever stored anywhere else than on your computers. There is no central server that might be compromised, legally or illegally.
  • Encrypted. All communication is secured using TLS. The encryption used includes perfect forward secrecy to prevent any eavesdropper from ever gaining access to your data.
  • Authenticated. Every node is identified by a strong cryptographic certificate. Only nodes you have explicitly allowed can connect to your cluster.

  • Syncthing in the official Arch Linux [community] repository – Syncthing Forum

Open Development

  • Open Discourse. Development and usage is always open for discussion.

Syncthing Discussion Forum
* Open Source. All source code is available on GitHub — what you see is what you get, there is no hidden funny business.

Syncthing Source Code
* Open Protocol. The protocol is a documented standard — no hidden magic.

Syncthing Protocol Definition
* Open Development. Any bugs found are immediately visible for anyone to browse — no hidden flaws.

MEGAsync For Linux Desktops MEGA.co.nz Linux Sync Client

MEGAsync for Linux comes with most features available for other similar tools (like Dropbox): the tray icon displays the sync status (and if you use the Nautilus extension, the files have emblems which show their sync status), it supports selective sync, you can use proxies, you can copy a public link for a file via the Nautilus context menu and so on.

There are also some extra features: you can upload a link to MEGA directly from the tray/appindicator app and import links to your MEGA account

MEGA currently provides a multi-platform software development kit, and we have plans to release the source code to MEGAsync under an open-source license.

cool-old-term is dead, long live cool-retro-term | Swordfish’s Labs

But why?… Well, cool-old-term was a sort of boilerplate name I chose at the beginning of the project and it stuck when the project became more popular. cool-retro-term keeps familiarity and has a very cool acronym so we can talk nerdy: “Have you tried CRT. It’s really great!”.
