Installed easily and running great.
Let me know if you need any help getting onto your C720.

Thanks

Great stuff .. I always wondered how well it'd run on an x86 Chromebook ?

I know perknh was having problems getting his to boot from LiveUSB .. maybe you can provide details ?

or maybe at some point you'd like to write a full tutorial and post it in the user submitted tutorial forum ? .. that would probably be extremely useful for some people :)

Your call.

Hi lend27,


I agree completely with PCNetSpec about the tutorial!! In any case, could you run and post here the results of this command (run in a terminal session) in your C720:

Hello lend27,

Yes, everything PCNetSpec said about my having difficulty booting P5 (back then) on to the Chromebook is absolutely correct.  But, here's the thing, it's no longer my Chromebook.  It's Mrs. perknh's Chromebook now!  And, her rules are quite simple concerning the device.  Don't touch the thing --unless she's having a problem with it, of course!  ;D (See I had messed with the thing, and I then had to do a fresh install of Chrome OS.  :-[)

I did get get ChrUbuntu to work on the C720, but what I really wanted was to either put Peppermint within Developer's Mode, or have Peppermint boot up from a Flash drive that has persistence added to it.  I just wanted to have Skype in Peppermint for the Chromebook when I needed it.

Doesn't the C720 have great audio?  It really is a terrific little device.   You managed to put Peppermint on to the device, and, for me, that is amazing news.  So far now, the only two distributions I've heard successfully placed on to a Chromebook are Bodhi Linux, and now Peppermint 6 --thanks to you.

Congratulations to you, lend27, for what you've accomplished here.  ;)

[T]here are a lot of people happily running Peppermint ICE which hasn't been receiving ANY updates for a while now .. and I personally would STILL consider that MUCH more secure than any version of Windows with up-to-date AV/Anti-malware ;)

OK, here we go.

I've had my Acer C720 chromebook for about 6 months.
First I installed crouton linux alongside the Chrome OS.  I realized I wasn't really using chrome anymore so decided to erase chrome and install full time linux.
I then researched and found Huge Green Bugs website, Distroshare, and he has several linux distros modified for the C720, so I tried a few of those. Very nice, but since I run Peppermint on my desktop I figured I would try it.

I downloaded and installed to USB. I actually tried it with Unetbootin on linux but had problems. Then I went to my windows install and used Rufus to install.  I also tried Win32 imager in windows. Had problems with all 3. Keep in mind you have to install Seabios onto your chromebook to be able to legacy boot from usb.  There are tutorials for that online. If you need me to point you to the right tutorial let me know. Once you have Seabios enabled, you insert the Peppermint USB and turn on the chromebook. There will be a prompt to hit the escape key to bring up the usb boot menu. Then you select 1 to boot from USB. I think Unetbootin will work fine for most of you. My initial problems were related to the boot issue outlined below.

The Peppermingt install menu will come up, but don't select anything. It will not boot as is. It will give you an error message saying "insufficient ram to boot the image".
You have to hit the tab key, then you will see the boot code at a CLI prompt. The line ends with "--" or "---". ( 2 or 3 dashes) .
*** At the end of that line add a space, then enter "mem=1590m" . Once you have the entered, click on install peppermint from the menu and it will change to a white screen. Don't do anything, just wait and it will eventually change to the Peppermint install screen.  Just install as you would normally.
Once the install is done, remove the USB and reboot.
It will automatically boot to a usable Peppermint install.
Now, one more critical item.

My chromebook has 4 gig of ram.
*** The instructions I found online tell you to add a line to the boot code that says "mem=4g".  This does not work.
Follow my instructions above which will get you a working system. Then once you have your install done, you will need to go into boot.cfg and take all references to "mem=1590m" out. Just open leafpad and search for "mem=". This will highlight the references to "mem=1590m". Once you remove all references, ( just delete that text, not the entire line that it is in), reboot and your system recognize the full amount of ram you have installed.  Until you remove that text your system will only show 1590m of ram. I verified all of these steps with my own install.

The nice thing is I didn't have to struggle to get anything working so far. Other distros have an issue with the trackpad, requiring debugging. Not so with Peppermint. Trackpad and everything else seems to work just fine.
I even installed Steam and am able to play most games, even Xcom Enemy Unknown.
Ice is working fine, Kodi, Geary, Chrome, Gthumb, Banshee, VLC.

Here is a screenshot:

Any questions let me know.

Thanks for that lend27, I'd not heard of seabios or the memory trick .. useful info for when the next person comes asking :)

One of the guys on the Mintcast when they reviewed Peppermint mentioned he couldn't install it on his chromebook because it said insufficient RAM .. I take it mem=1590m is the workaround for that ?

Yes, Seabios is a must and the ram instructions are a workaround for the insufficient ram issue.

Either of these will get the job done:

Just follow the steps until it's time to install the distro and then work with Peppermint.
IMHO, this first link is the easiest to follow step by step.
If you follow until the section "some potential issues", you should have a working Peppermint system. Don't mess with the other issues he addresses until you use your chromebook with Peppermint for awhile. Most of the issues are non-issues now with the kernel upgrades.
The volume and brightness keys are not mapped correctly though. I am still trying to get that fixed. I will post a fix asap.
The back of the chromebook is actually easy to remove. Just follow the steps. A guitar pick or other thin plastic item will work. Once you get a corner seperated, the rest should be easy.
BTW, I replaced the orig SSD with a 120gig model and it works fine. Plenty of instructions avail online for that.

NOTE: Some of these guides do not address the RAM issue. Please make sure you follow my instructions on that or you will not get the chromebook to boot from your peppermint USB stick. VERY IMPORTANT.

To clarify:

When you are at the step where you boot from the usb, make sure you press "escape" to enter the boot options menu. Select 1 to boot from USB. This will bring up the Peppermint install menu. Do not select anything. Instead, press "Tab" then at the end of the long boot instruction line which ends with some dashes (either -- or ---) add a space after the dashes, then type "mem=1590m" without quotes. Then press enter. This will bring up a white screen. Just wait patiently and the Peppermint install screen will appear. Then just follow as you normally would to complete the install. Once the install finishes, press restart and as soon as the screen goes black remove the usb stick. It will not boot to the hard drive with the usb stick inserted. Once you remove the usb stick, the system will boot to your new shiny Peppermint install. Play around a bit to check things out. Once you feel comfortable, modify the grub.cfg file to remove the references to "mem=1590m". If you dont do this, the system will only recognize that amount of ram. In my case I have 4g and of course I wanted all of it available. Modifying the grub.cfg file will do that for you. I verified this before and after.

To modify the grub.cfg file, I opened a terminal and installed Leafpad. Then I entered the command "gksudo leafpad". I entered my password and leafpad opened. I clicked on "file" from the Ieafpad menu, then click on "open", then click on "File System", then click on "boot", then click on "grub", then open "grub.cfg". I opened the file and used the "search/find" command to locate all references to "mem=". This highlighted the text that had to be removed. Remember to only remove that specific text, not the entire line that it is in. Do that with each reference. Then, to be safe, use the find command again to make sure you got them all. Then save the file and reboot. Now all of your ram will be available to your system.

Good Luck!
