Got a Screwdriver? GalliumOS Can Turn Chromebooks Into Linux Boxes

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

My current
assessment of a brand new Chromebook characteristic — the flexibility 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 resolution. It requires making a bodily adjustment contained in the and flashing new firmware earlier than the GalliumOS set up ISO will boot. However, it may be a useful workaround in case your Chromebook doesn’t assist Linux apps and/or Android apps.

If you observe instructions explicitly and might 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 can set up it as a totally useful substitute for the ChromeOS on a suitable Chromebook. You can set up it as a twin boot to provide you each ChromeOS and a whole Linux distro on one light-weight transportable pc.

After I efficiently flashed the replace firmware to the ageing Chromebook and succeeded in booting the dwell session GalliumOS, I used to be interested in how supportive the adjustments can be for different Linux distros. I tried booting the Chromebook into two different Linux dwell periods I beforehand examined for opinions on USB drives.

The GalliumOS firmware substitute solely works with this distro. Both Puppy 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 mixtures ultimately. Older expertise makes use of Crouton to put in different suitable Linux distros, corresponding to Ubuntu or Linux Mint or Arch Linux.

Checking Out GalliumOS

My best computing platform is in a state of transition this previous 12 months. I began to combine the Chromebook with its added flexibility from Android apps. Then I expanded that flexibility by including a couple of Linux apps to the combo on a Chromebook.

I began to benefit from the extraordinarily light-weight Chromebook with its superpowers from Android and Linux apps operating on the ChromeOS. I found myself spending extra time working exterior of my workplace and its massive screens with full-blown Linux working methods. 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 useful Linux machine operating GalliumOS. Now I have to rethink my requirements for what contains my best 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 Offers

GalliumOS relies on Xubuntu. GalliumOS consists of optimizations and lots of fixes for the ChromeOS-based . This retooling drastically reduces system stalls and improves total responsiveness.

It runs the Xfce desktop. This is the default desktop for Xubuntu, and it’s a sensible choice for the light-weight 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 almost instant-on efficiency of ChromeOS on Chromebooks. Much of that velocity outcomes from fewer providers, a smaller kernel, and the Lightweight Display Manager (LXDM).

The Xfce desktop GalliumOS runs is full of options and configuration choices. You can use the default settings for a lovely, environment friendly, out-of-the-box expertise or create a extra customized desktop look.

What It Is

GalliumOS 2.1 was launched early final 12 months, which makes the distro a bit overdue for a serious release improve. However, it really works fairly effectively and does get common package deal and system updates.

The newest alpha model of GalliumOS three is model three.0alpha1 launched this summer season. Since I’m experimenting with this course of, I examined the older secure model. This ranges the sector through the use of a recognized dependable ISO with fixes and updates already in place.

You can obtain GalliumOS 2.1 set up photos
right here. The make and mannequin of your Chromebook, together with its processor title, will decide which ISO to get. You can discover that data from producers’ web sites, the Chromebook’s documentation, or from the GalliumOS compatibility chart referenced on this assessment.

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

Challenging Process

This distro requires appreciable preparation to the Chromebook earlier than you possibly can run the dwell session or set up it. Of course, you possibly can reverse the adjustments and restore the ChromeOS in the event you dislike GalliumOS.

However, be forewarned. Getting to the dwell session stage takes some work. Undoing that work is a bit quicker, since you are already conversant in the method.

The further effort in transitioning the Chromebook right into a Linux field could be well worth the effort. The course of is a bit daunting in the event you have by no means toyed with the innards of a pc. That mentioned, the quite a few hours I spent researching the steps and trying trial-and-error conversations paid off.

Before beginning this course of, save any domestically saved paperwork, audio and video recordsdata. Along the way in which, your Chromebook will reset and take away these recordsdata. Files already saved in your cloud account — Google Drive or Dropbox, as an example — won’t be harmed.

One of essentially the most vital steps within the course of is opening the Chromebook to disable write safety. You is perhaps fortunate and never have to carry out this process in your Chromebook mannequin, however extra Chromebooks than not want this accomplished. Otherwise, the ISO won’t load.

That is the primary 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

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

Check the compatibility chart
right here. Write down three key gadgets from the chart: Model, Hardware ID and Processor. You will want them for getting the proper firmware substitute and write shield location.

Chromebooks with Sandy Bridge, Ivy Bridge or Bay Trail processors want the bodily write safety eliminated. To discover out what to do about eradicating write safety, do a Web search utilizing the mannequin or ID. Use this search string. Do not embrace citation marks or caret symbols.

” chromebook disable write-protect”

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

  1. Remove the 12 or extra screws that rim the underside panel of your Chromebook.
  2. Carefully loosen the sides of the panel and pull it from the remainder of the chassis.
  3. Then observe the knowledge you found on eradicating the write safety bodily machine.

Chromebooks with Sandy Bridge, Ivy Bridge and Bay Trail processors require removing of the bodily write safety. On some items, you do 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 customary Linux instruments to burn the set up to DVD from the downloaded ISO. Use one other pc to organize the USB drive or SD card. Download Etcher
right here. You can hold the Etcher file in your Download folder together with the proper ISO file you downloaded from the GalliumOS Website.

It is a three-step course of. Etcher has a easy person interface. Some USB drives are finicky with regards to making a bootable partition, so have a number of completely different producers’ drives readily available. I went by two USB drives earlier than it labored.

Click on the Etcher software to begin the method. When Etcher masses, click on the primary button labeled “Select Image.” Point the file picker to the GalliumOS ISO file.

Then click on on the second button, “Select Drive,” to click on on the situation of the USB drive or SD card. Do not choose the flawed machine. The formatting course of will destroy all current knowledge on the chosen machine.

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

Moving to Developer Mode

In order to let the Chromebook boot from the dwell session USB drive or SD card, you need to boot it into Recovery 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) + Power.

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

The display now shows the Recovery Mode boot warning that “ChromeOS is damaged or missing.” Do not panic. It is neither lacking nor broken.

Switch the Chromebook into Developer Mode and allow legacy boot mode. This is completely different from switching to the Developer Channel from inside a operating ChomeOS session. Enabling Developer Mode will erase all person knowledge in ChromeOS.

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

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

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

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


Ready to Go

Well, possibly. If your Chromebook’s firmware already helps booting from USB or SD gadgets, you now are able to run GalliumOS in dwell session.

With the Developer Mode display seen, press the CTRL + L keys to reboot the Chromebook from the exterior machine. Each time you exit GalliumOS or energy off the Chromebook, whenever you restart the pc it would boot into the Developer Mode display. Start GalliumOS once more by urgent CTRL + L.

Once you put in the Linux OS, the Chromebook will boot instantly into the GalliumOS.

Transplanting Firmware

If your Chromebook has one of many processors famous earlier, You 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.

Once you might be signed into ChromeOS, open a ChromeOS terminal or Crosh window by urgent CTRL+ Alt + T. At the immediate, enter the command “shell” and press the Enter key. (Do not use the apostrophe marks.)

At the [email protected] / $ immediate, enter this command line:

sudo crossystem dev_boot_legacy=1

Once once more, you have to the Hardware ID and CPU household from the chart beforehand talked about.

Use the Chromebook’s Web browser to return to the Hardware Compatibility Custom Firmware web page. Go to the column the place your Chromebook’s title and mannequin are listed.

Find the hyperlink supplied and click on it to begin 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. At the BIOS display, press the Esc button after which choose the USB or SD machine.

Your Chromebook will boot into dwell session mode. When you put in GalliumOS and reboot the pc, it would boot into Linux robotically with no hint of the ChromeOS.

Success: After modifying and firmware, the Chromebook boots from USB or SD gadgets to run GalliumOS.


Keyboard Tinkering Needed

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

Instead, you depend on workarounds designed into GalliumOS. The distro consists of 5 keyboard layouts custom-made for Chromebooks. Configure them from the GalliumOS/Whisker Menu, in Settings >> Keyboard >> Layout >> Keyboard Model.

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

To modify the performance of a key, change the suitable file. For occasion, to remap the facility key to Delete, add the next line within the applicable file: key ; and set the facility button to “Do nothing” within the Power Manager menu.

Solid 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 useful Linux mini laptop computer. The configuration consists of an Intel Celeron 2955U 1.four GHz (2 MB Cache) processor with 2 GB of DDR3L SDRAM. The unit has a 32-GB Solid-State Drive, a 12-Inch Screen and Intel HD Graphics.

GalliumOS with the Xfce desktop drives this a lot better than did the ChromeOS. I used to be not happy with the sluggishness that resulted when too many Chrome browser tabs have been opened. The ChromeOS typically appeared to simply 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 exchange ChromeOS drastically improved this Chromebook’s efficiency. The default Chromium browser was much less peppy. I solved that weak spot 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 almost 9 hours. That certain beats the battery energy of my latest laptops operating different Linux distros.

The Synaptic Package Manager 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 Web browser is the one supplied browser. It is lighter than Google Chrome however nonetheless offers entry to Google’s software program infrastructure.

Bottom Line

The variety of purposes you construct into GalliumOS relies on the SSD or HD storage of the host Chromebook. In the case of the Acer C720’s 32-GB Solid State Drive, the default set up — together with a couple of massive 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 house.

The C720’s is ageing. I have no doubts that GalliumOS performs way more energetically on newer configurations. Still, given the unique low value I paid for the Chromebook a bunch of years in the past, and the zero price of downloading the Linux OS and the firmware, I have 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 problem with not having an Internet connection to make use of the ChromeOS apps. That is a non-issue operating Linux on the Chromebook.
