Partly updated June 2023
General caution: Chrome OS is a secure OS by design, but this has at least one key consequence. If you change your Google account password, you will still be required to enter the old password the next time you access each Chrome OS device. Devices are encrypted with that password, so the OS needs to decrypt using the old password then re-encrypt using the new one. If you forget your old password you will lose access to your Chrome OS device data. As always, make sure you keep backups up to date.
If you have multiple Chrome OS accounts (Say, work and play), you can quickly sitch between them without logging out:
- Open the status area (the bottom-right menu)
- Click your account photo.
- Click Sign in another user.
- You'll see a reminder to use the feature only with people you trust. Click OK.
- Pick a person, then enter their password. You can add up to 7 users. Warning: sme sorts of Google accounts can only be used as the primary (first set up) account on a chromebook.
You can then quick-switch between users with CTRL+ALT+, & CTRL+ALT+.
Pixelbook's power button (but apparently not the Slate's) has a built-in 2fa/2sv key (think YubiKey), but it's disabled by default. If you use Two-Factor authentication on GitHub, Gmail etc, you can turn it on by entering this command on the Crosh shell (Ctrl+Alt+T):
u2f_flags u2f,user_keys
- Select the time in the bottom right to open your status area.
- Select Settings, then Advanced
- Under "Linux development environment" select Turn On.
- Follow the steps on the screen. Setup can take 5 minutes or more.
- A terminal window opens. You can run Linux commands, install more tools using the APT package manager (see below), and customize your shell.
sudo apt update && sudo apt dist-upgradeNote: some guides out there suggest setting the root password, but never do that unless you absolutely know what you're doing. If you need to use a feature that requires a password for root, set it on the Crostini default user instead:
sudo passwdSince you'll probably be doing some sort of software building or development, you should use install relevant packages
sudo apt-get install git build-essential libssl-dev libffi-devIf you're used to having certain system command line tools handy, you might need to install them on debian. I do:
sudo apt install mtr dnsutils vim nanoActually I don't usually bother with nano, as I just deal with vim, but if you like that text editor better, it will be installed from the above. These days I use mtr rather than ping & traceroute, but if you want to go old school you can do:
sudo apt install dnsutils traceroute iputils-pingYou might also want some other useful tools. I do:
sudo apt install zip whois tree xclipThe Debian install on ChromeOS/Linux is "stable", only, and generally has only older Python versions available. We need to add sid for optional installs of more recent software. Step 1 is to add the repository. Edit (using vi or nano), e.g. sudo vi /etc/apt/sources.list and append the following as the new last line:
deb http://http.us.debian.org/debian sid main non-free contrib
Now the next step is important before you do anything more with apt, or you can make quite a mess. We only want to use sid packages if we exlicitly ask for them create a new file, e.g. sudo vi /etc/apt/preferences with the following contents:
Package: *
Pin: release a=stable
Pin-Priority: 700
Package: *
Pin: release a=testing
Pin-Priority: 650
Package: *
Pin: release a=unstable
Pin-Priority: 600
Now you can install Python 3.11 as follows:
sudo apt -t sid install python3.11Recent versions of many other packages should now be available.
Prepare:
mkdir -p $HOME/.local/venvMake a virtualend called main. Use a different name, if you prefer:
/usr/bin/python3.11 -m venv $HOME/.local/venv/mainYou only need to specify the full path to Python when creating the venv, as above.
Activate:
source $HOME/.local/venv/main/bin/activate
pip install --upgrade pip #Needed from time to time, to make sure pip itself is up to date
pip install wheel #One time per venv. Allows pip to install pre-compiled os-specific versions. Also you might get odd errors if you omit this.
In future you only need the first line above to activate the venv.
I prefer to use an Ed25519 key.
ssh-keygen -o -a 100 -t ed25519 -f ~/.ssh/id_ed25519 -C "my_name.pixelbook"
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_ed25519
cat .ssh/id_ed25519.pub
# Paste in GitHub/GitLab/etc.In order to make sure SSH agent starts automatically, and that only one ssh-agent process runs at a time, add the following to .bashrc:
if ! pgrep -u "$USER" ssh-agent > /dev/null; then
ssh-agent > ~/.ssh-agent-thing
fi
if [[ ! "$SSH_AUTH_SOCK" ]]; then
eval "$(<~/.ssh-agent-thing)"
fiI prefer to just after each restart enter:
ssh-add ~/.ssh/id_ed25519But there are tools I've used in Linux to automatically pop up a prompt if a key hasn't been registered with the agent.
I then follow these Python dev setup steps for Linux
Warning: Until this bug is addressed Crostini containers only grow in disk space; they never shrink, even if you delete files within them.
The main approach to backup is to export the entire container:
- Enable the "Crostini Backup" Flag – chrome://flags/#crostini-backup, then choose Restart
- Open chrome://settings/crostini/exportImport and select "Backup" followed by "Save". Ideally save this on a external drive.
To restore:
- Open chrome://settings/crostini/exportImport and select "Restore". Select the export archive file. After it's done the exported version of Crostini should be in place.
Now automatic between Chrome OS and Linux. You'll find Linux files/directories in the Files app, under "Linux Files".
In order to access Chrome OS files you must make the desired folder or removable device available to Linux by right clicking in the Files app and selecting the option. Note: It seems you might have to reboot the device before this "Share with Linux" option appears.
Go to the files app and right click on Google Drive, then click "Share with Linux"
Files will be available under: /mnt/chomeos/Googledrive
Download the Linux package. Install with Linux.
If you just launch & click "Sign in" you'll eventually land at the error: "We’re sorry It looks like you are on a device that we don’t yet support."
Instead just go to https://[your-channel].slack.com/ssb/signin_redirect/fallback, click "Copy sign-in key" then launch slack, which will automatically pick up the magic key from your clipboard. Repeat for any other accounts you have.
Unfortunately Dropbox support for ChromeOS is poor. Main recommendation seems to be the third-party File System for Dropbox but it doesn't support offline access. The official Dropbox Linux client ended support for all file systems except unencrypted ext4, which rules it out for crostini. Looking into rclone and just using the Web client for now.
I tried the Skype for Linux DEB, but the microphone didn't work on Pixel Slate, and I've heard screen sharing might not work. I might try the Android app, but for now I'm just switching as much as I can to Google Meet.
Crostini (the Linux container on Chrome OS) understands Debian installation packages (.deb) - You can just download any installer and double-click it to install.
And, being debian you also have apt, though in this case you might need to set up the installed apps to be launched by icon by placing a desktop file in /usr/local/share/applications/. Details here.
sudo mkdir -p /usr/local/share/applicationsSome examples next
So many choices, and so manby combos of distinct and/or overlapping and/or complementary tools. I'm trying just Extraterm

I was using TextMate on Mac and Atom in my Linux Mint installs. I'm not much of a fan of IDEs, but VSCode seems really popular among Pixelbook users, so I'll give it a whirl.
Download the .deb installer from atom.io (or the beta version of Atom if you prefer). Click "Show in folder" right click then "Install in Linux"
Download via chrome and click through to the download location in Files app. Right click then "Install in Linux"
If you use VSCode for Python dev and want to use VSCode plugins you'll want to do:
sudo apt install python3-pip
Coming from Mac OS's excellent setup for international character entry I have to say ChromeOS falls quite short. From the commonplace (SHIFT+OPTION+ - = em dash) to the less common (ALT+ e / i / SHIFT+ALT+ x = Igbo nasal i with rising tone) such keyboard shortcuts are nowhere to be found.
Best friend is probably the Unicode entry hotkey CTRL+SHIFT+ u. When you press this you get an underlined u and you can type in a 4 digit hex Unicode value to get the character. Then you just have to remember your faborites (e.g. 2014 = em dash) or print out a chart to have handy. Here is a handy table.
There is the US International Keyboard (add it from the Input Methods menu near the screen bottom right), but if you mix other languages with English, you'll be annoyed e.g. that a regular apostrophe is always an accent acute.
Tip from mannkeithc on Reddit:
Flip your Pixelbook into tablet mode, and use the onscreen virtual keyboard. You can hold down a character key and then slide over to the respective international character you want—very similar to an iPad or Mac OS. Bring this same virtual keyboard onto the screen when you are in clamshell/laptop mode by first selecting "Handwriting input". This brings up a virtual input area. Select the keyboard symbol towards LH top of this window to get the virtual keyboard. You can then use the touch screen as in tablet mode to select the international characters you want.
On MacOS and Linux I've become used to the convenience of clipboard managers which e.g. allow you to manage a history of cut & paste, which can be very handy especially when editing code. It seems Clipboard History Pro is the favorite choice of ChromeOS power users, but it's not yet entirely growing on mw. The keyboard shortcut doesn't seem to work and some of the other config options seem flaky. One note: it only stores the clipboard in your local browser storage, unless you explicitly upload an item to cloud storage (a useful feature), but I still recommend you never copy sensitive data such as passwords with any such tool.
Pixelbook and Pixel slate are of course touch and pen devices, but you probably don't need to buy Google's $100 pen. You can find the Lenovo Active Pen 1 for about $20 and I was able to buy the Lenovo Active Pen 2 for just over $30. Many reviews indicate that these work as well for all but the most advanced users.
You can use the standard Python mechanism
python -m webbrowser -t http://www.google.com
Or you can use garcon:
/usr/bin/garcon-url-handler https://www.google.com
If you want to change the browser used, set the BROWSER environment variable.
Some fonts can be installed using apt, for example I use Inconsolata
sudo apt install fonts-inconsolata -y
sudo fc-cache -fvIf you just have the font file:
- Copy .ttf file to ~/.local/share/fonts
fc-cache -vf ~/.local/share/fonts
fc-list | grep [your font name] # To verifyThe Pixelbook has a high-density display (HiDPI, roughly equivalent to the "Retina display" term if you're comming from a Mac), but not all Linux apps are prepared to appear correctly in HiDPI displays. They can appear small or have regular size with tiny cursor...
The good news is that you can use ChromeOS's built-in tool Sommelier to customize zoom levels for linux applications.
See also this reddit thread.
Many installed programs will generate a .desktop file in /usr/share/applications, it contains an app description as well as its icon and launch command.
Change Exec entries to specify Sommelier's DPI and zoom level:
[Desktop Entry]
Name=Visual Studio Code
Comment=Code Editing. Redefined.
GenericName=Text Editor
Exec=sommelier -X --scale=0.7 --dpi=160 /usr/share/code/code "--unity-launch %F"
Icon=code
Type=Application
StartupNotify=true
StartupWMClass=Code
Categories=Utility;TextEditor;Development;IDE;
MimeType=text/plain;inode/directory;

[Desktop Action new-empty-window]
Name=New Empty Window
Exec=sommelier -X --scale=0.7 --dpi=160 /usr/share/code/code "--new-window %F"
Icon=code
Specifically for VSCode, I would also suggest adding these to your user settings
"window.titleBarStyle": "custom",
"window.zoomLevel": 2,
"editor.mouseWheelScrollSensitivity": 0.5
- Pixelbook keyboard shortcuts
- r/Crostini subreddit Wiki--huge wealth of useful info
- If your world extends beyond English-only: Choose the keyboard language & special characters on your Pixelbook
The scaling tips work for X perhaps. Any ideas how one can apply DPI and scaling for native wayland GUI apps?
