Got a Screwdriver? GalliumOS Can Turn Chromebooks Into Linux Boxes

GalliumOS is a Chromebook-specific Linux variant. It enables you to put an actual Linux distro on a Chromebook.

My latest
overview of a brand new Chromebook characteristic — the power to run Linux apps on some Chromebook fashions — sparked my curiosity in different applied sciences that run full Linux distros on some Chromebooks with out utilizing ChromeOS.

GalliumOS isn’t an ideal answer. It requires making a bodily adjustment contained in the {hardware} and flashing new firmware earlier than the GalliumOS set up ISO will boot. Nevertheless, it may be a useful workaround in case your Chromebook doesn’t assist Linux apps and/or Android apps.

In case you comply with instructions explicitly and may wield a screwdriver to take away the underside panel, GalliumOS is an ingenious Linux distro that may provide the better of two computing worlds. You possibly can set up it as a totally purposeful substitute for the ChromeOS on a appropriate Chromebook. You possibly can set up it as a twin boot to present you each ChromeOS and a whole Linux distro on one light-weight moveable pc.

After I efficiently flashed the replace firmware to the growing older Chromebook and succeeded in booting the dwell session GalliumOS, I used to be interested in how supportive the adjustments could be for different Linux distros. I attempted booting the Chromebook into two different Linux dwell classes I beforehand examined for critiques on USB drives.

The GalliumOS firmware substitute solely works with this distro. Each Pet Linux and Quirky Linux didn’t boot with the Gallium OS firmware. It additionally doesn’t work on all Chromebooks. The GalliumOS builders hope to have variations for all {hardware} mixtures ultimately. Older know-how makes use of Crouton to put in different appropriate Linux distros, reminiscent of Ubuntu or Linux Mint or Arch Linux.

Checking Out GalliumOS

My splendid computing platform is in a state of transition this previous yr. I began to combine the Chromebook with its added flexibility from Android apps. Then I expanded that flexibility by including just a few Linux apps to the combination on a Chromebook.

I began to benefit from the extraordinarily light-weight Chromebook {hardware} with its superpowers from Android and Linux apps operating on the ChromeOS. I discovered myself spending extra time working outdoors of my workplace and its giant displays with full-blown Linux working programs. The Chromebook’s smaller and lighter footprint provided a pleasant change of tempo from engaged on bulkier laptops operating full Linux configurations.

I efficiently repurposed an older Chromebook to remodel it into a totally purposeful Linux machine operating GalliumOS. Now I’ve to rethink my requirements for what contains my splendid computing platform.


GalliumOS Xfce desktop

GalliumOS runs the Xfce desktop as an alternative of ChromeOS to place a contemporary spin on a conventional Linux platform.


What It Presents

GalliumOS is predicated on Xubuntu. GalliumOS contains optimizations and lots of fixes for the ChromeOS-based {hardware}. This retooling vastly reduces system stalls and improves general responsiveness.

It runs the Xfce desktop. That is the default desktop for Xubuntu, and it’s a good selection for the light-weight {hardware} specs of most Chromebooks. The OS carried out quick, each within the dwell session delivered from the USB drive and later as absolutely put in.

GalliumOS has a noticeably quicker bootup. It boots quicker than different Linux distros, virtually matching the practically instant-on efficiency of ChromeOS on Chromebooks. A lot of that pace outcomes from fewer companies, a smaller kernel, and the Light-weight Show Supervisor (LXDM).

The Xfce desktop GalliumOS runs is filled with options and configuration choices. You should use the default settings for a delightful, environment friendly, out-of-the-box expertise or create a extra personalised desktop look.

What It Is

GalliumOS 2.1 was launched early final yr, which makes the distro a bit overdue for a significant launch improve. Nevertheless, it really works moderately nicely and does get common package deal and system updates.

The most recent alpha model of GalliumOS Three is model 3.0alpha1 launched this summer season. Since I’m experimenting with this course of, I examined the older secure model. This ranges the sphere by utilizing a identified dependable ISO with fixes and updates already in place.

You possibly can obtain GalliumOS 2.1 set up photographs
right here. The make and mannequin of your Chromebook, together with its processor identify, will decide which ISO to get. You could find that data from producers’ web sites, the Chromebook’s documentation, or from the GalliumOS {hardware} compatibility chart referenced on this overview.

You possibly can preview GalliumOS in a “dwell boot” surroundings from the identical picture with out absolutely putting in it. Nevertheless, attending to the dwell session isn’t so simple as burning an ISO to a USB drive and rebooting the Chromebook.

Difficult Course of

This distro requires appreciable preparation to the Chromebook earlier than you possibly can run the dwell session or set up it. After all, you possibly can reverse the adjustments and restore the ChromeOS for those who dislike GalliumOS.

Nevertheless, be forewarned. Attending to the dwell session stage takes some work. Undoing that work is a bit quicker, since you are already accustomed to the method.

The additional effort in transitioning the Chromebook right into a Linux field will be definitely worth the effort. The method is a bit daunting when you’ve got by no means toyed with the innards of a pc. That stated, the quite a few hours I spent researching the steps and making an attempt trial-and-error conversations paid off.

Earlier than beginning this course of, save any regionally saved paperwork, audio and video information. Alongside the way in which, your Chromebook will reset and take away these information. Information already saved in your cloud account — Google Drive or Dropbox, as an illustration — won’t be harmed.

One of the vital essential steps within the course of is opening the Chromebook to disable write safety. You may be fortunate and never should carry out this process in your Chromebook mannequin, however extra Chromebooks than not want this carried out. In any other case, the ISO won’t load.

That’s the first a part of the conversion process. The second half is flashing firmware to allow the brand new OS to run in your Chromebook.

Know What You Have

Relying in your Chromebook, the BIOS is write-protected both by way of bodily or software program strategies. The standard method controls write safety with a screw on the motherboard. Some fashions have conductive stickers. A number of older fashions have a jumper. One other variable is their location and look. In all instances, you possibly can entry them solely by opening your system.

Verify the {hardware} compatibility chart
right here. Write down three key objects from the chart: Mannequin, {Hardware} ID and Processor. You’ll need them for getting the right firmware substitute and write shield location.

Chromebooks with Sandy Bridge, Ivy Bridge or Bay Path processors want the bodily write safety eliminated. To seek out out what to do about eradicating write safety, do a Internet search utilizing the mannequin or {hardware} ID. Use this search string. Don’t embrace citation marks or caret symbols.

Typically, the process is similar to what I did with my Acer C720 Chromebook. Use a small Phillips head screwdriver.

  1. Take away the 12 or extra screws that rim the underside panel of your Chromebook.
  2. Rigorously loosen the sides of the panel and pull it from the remainder of the chassis.
  3. Then comply with the data you discovered on eradicating the write safety bodily system.

Chromebooks with Sandy Bridge, Ivy Bridge and Bay Path processors require removing of the bodily write safety. On some items, you try this by eradicating a screw from the motherboard.


Making a Bootable USB Drive or SD Card

This course of is a bit completely different from utilizing commonplace Linux instruments to burn the set up to DVD from the downloaded ISO. Use one other pc to arrange the USB drive or SD card. Obtain Etcher
right here. You possibly can maintain the Etcher file in your Obtain folder together with the right ISO file you downloaded from the GalliumOS Web site.

It’s a three-step course of. Etcher has a easy consumer interface. Some USB drives are finicky in terms of making a bootable partition, so have a number of completely different producers’ drives readily available. I went by way of two USB drives earlier than it labored.

Click on on the Etcher utility to start out the method. When Etcher hundreds, click on the primary button labeled “Choose Picture.” Level the file picker to the GalliumOS ISO file.

Then click on on the second button, “Choose Drive,” to click on on the placement of the USB drive or SD card. Don’t choose the improper system. The formatting course of will destroy all current information on the chosen system.

Lastly, click on the button marked “Flash.” After a couple of minutes, the file burning course of will full. You at the moment are able to proceed with the software program infusion onto your Chromebook.

Transferring to Developer Mode

To be able to let the Chromebook boot from the dwell session USB drive or SD card, you should boot it into Restoration Mode to modify over to Developer Mode. First, with the Chromebook turned off, plug in your bootable USB drive or SD card with the GalliumOS put in. To activate the Chromebook, press Esc + F3 (refresh) + Energy.

Some Chromebook fashions lack perform keys. Search for the refresh image on a key on the highest keyboard row. It exhibits a round arrow.

The display screen now shows the Restoration Mode boot warning that “ChromeOS is broken or lacking.” Don’t panic. It’s neither lacking nor broken.

Change the Chromebook into Developer Mode and allow legacy boot mode. That is completely different from switching to the Developer Channel from inside a operating ChomeOS session. Enabling Developer Mode will erase all consumer information in ChromeOS.

Press [Ctrl+D] to allow Developer Mode. Then comply with affirmation steps by urgent enter when requested.

This can take some time. When the method is accomplished, the Chromebook will beep twice and show a brand new white display screen. Click on the blue “Let’s go” button to proceed.

The Chromebook will reboot to a white display screen that claims “OS verification is OFF.” That is Developer Mode.

This display screen show confirms a profitable swap to Developer Mode on the Chromebook.


Able to Go

Nicely, possibly. In case your Chromebook’s firmware already helps booting from USB or SD units, you now are able to run GalliumOS in dwell session.

With the Developer Mode display screen seen, press the CTRL + L keys to reboot the Chromebook from the exterior system. Every time you exit GalliumOS or energy off the Chromebook, once you restart the pc it’s going to boot into the Developer Mode display screen. Begin GalliumOS once more by urgent CTRL + L.

As soon as you put in the Linux OS, the Chromebook will boot instantly into the GalliumOS.

Transplanting Firmware

In case your Chromebook has one of many processors famous earlier, You might have yet one more main step to perform — flashing the firmware.

Now that you’re operating Chromebook in Developer Mode, signal into WiFi and settle for the Google Chrome OS phrases. Or you possibly can sign up as a visitor for the firmware replace.

As soon as you might be signed into ChromeOS, open a ChromeOS terminal or Crosh window by urgent CTRL+ Alt + T. On the immediate, enter the command “shell” and press the Enter key. (Don’t use the apostrophe marks.)

On the chronos@localhost / $ immediate, enter this command line:

sudo crossystem dev_boot_legacy=1

As soon as once more, you will want the {Hardware} ID and CPU household from the chart beforehand talked about.

Use the Chromebook’s Internet browser to return to the {Hardware} Compatibility Customized Firmware web page. Go to the column the place your Chromebook’s identify and mannequin are listed.

Discover the hyperlink supplied and click on it to start out the firmware obtain. This course of will take a number of minutes to finish

When the firmware obtain and set up are accomplished, reboot your Chromebook. On the BIOS display screen, press the Esc button after which choose the USB or SD system.

Your Chromebook will boot into dwell session mode. Whenever you set up GalliumOS and reboot the pc, it’s going to boot into Linux robotically with no hint of the ChromeOS.

Success: After modifying {hardware} and firmware, the Chromebook boots from USB or SD units to run GalliumOS.


Keyboard Tinkering Wanted

The less keys on the Chromebook keyboard is a matter. The Chromebook-specific mixture keys don’t work within the Linux distro. As an example, there isn’t any caps key. There is no such thing as a delete key. There are not any features keys. No num lock key or quantity pad.

As a substitute, you depend on workarounds designed into GalliumOS. The distro contains 5 keyboard layouts custom-made for Chromebooks. Configure them from the GalliumOS/Whisker Menu, in Settings >> Keyboard >> Structure >> Keyboard Mannequin.

You entry media and performance keys both with or with out urgent the chosen “Overlay” key first, relying in your selection of keyboard structure. These layouts are saved in /usr/share/X11/xkb/symbols/chromebook.

To change the performance of a key, change the suitable file. As an example, to remap the ability key to Delete, add the next line within the applicable file: key {[ Delete ] }; and set the ability button to “Do nothing” within the Energy Supervisor menu.

Strong Impressions

GalliumOS performs very reliably. The extra I used my favourite Linux apps on the Acer C720 Chromebook, the extra happy I turned with this light-weight and really purposeful Linux mini laptop computer. The {hardware} configuration contains an Intel Celeron 2955U 1.four GHz (2 MB Cache) processor with 2 GB of DDR3L SDRAM. The unit has a 32-GB Strong-State Drive, a 12-Inch Display and Intel HD Graphics.

GalliumOS with the Xfce desktop drives this {hardware} a lot better than did the ChromeOS. I used to be not happy with the sluggishness that resulted when too many Chrome browser tabs had been opened. The ChromeOS typically appeared to only limp alongside. I detected a few of that very same sluggishness with quite a few tabs opened within the default Chromium browser.

The optimized Linux innards the GalliumOS builders designed to interchange ChromeOS vastly improved this Chromebook’s efficiency. The default Chromium browser was much less peppy. I solved that weak point by operating the Firefox browser as an alternative.

The Chromebook was giving me eight hours of battery life. The “revitalized” Linux Chromebook stays alive for practically 9 hours. That positive beats the battery energy of my latest laptops operating different Linux distros.

The Synaptic Bundle Supervisor handles a gradual stream of system updates and software program additions/removals. The default software program is often mild for Xfce. No workplace apps are put in. The Chromium Internet browser is the one supplied browser. It’s lighter than Google Chrome however nonetheless gives entry to Google’s software program infrastructure.

Backside Line

The variety of purposes you construct into GalliumOS depends on the SSD or HD storage of the host Chromebook. Within the case of the Acer C720’s 32-GB Strong State Drive, the default set up — together with just a few giant added Linux purposes that embrace LibreOffice 5, Firefox browser, GIMP and the Geany IDE textual content editor — left me with 7.6 GB of free area.

The C720’s {hardware} is growing older. I’ve no doubts that GalliumOS performs rather more energetically on newer {hardware} configurations. Nonetheless, given the unique low value I paid for the Chromebook a bunch of years in the past, and the zero value of downloading the Linux OS and the firmware, I’ve no complaints.

Turning a Chromebook right into a “Linuxbook” additionally eliminates one of many long-standing criticisms of nonbelievers. I by no means had a difficulty with not having an Web connection to make use of the ChromeOS apps. That may be a non-issue operating Linux on the Chromebook.
