@perknh: Chrome OS is very limited.

Yeah, it sure is.  It's Chrome browser, with a few apps thrown in.

Maybe (sooner or later) I will get an Acer C720 myself.

The Acer C720 has a solid build, but it's becoming dated.  I put Peppermint 9 on a 14" refurbished HP Stream I picked up on eBay around Christmas for $119.  My little PepperNine works just fine, and I get to run Firefox on it too.  It's mrs.perknh who's got the Chromebook.  If I'm able to put Chromium OS on it through CloudReady and keep the thing going like it's going right now, I'll be happy with that. :)

For what it's worth, for about 15 minutes I had a Linux distribution on mrs.perknh's Chromebook.  When I tried to boot into Peppermint, I kept reading that the Acer c720 didn't have enough memory. (I had a P10 iso on a 16 G PNY flash drive)  So then I tried CloudReady, and I was told I hadn't Chrome OS.  So, for the hell of it, I then tossed a Sony 4 Gig flash drive into the Chromebook which had a Mint iso on it, and, to my surprise, it was acknowledged without warning as a 4 G Sony flash drive containing Mint! :o  So Installed Mint while downloading Peppermint in order to eventually replace Mint on the Sony flash drive.

Then I began playing with the installation in order to find a way to avoid booting directly into that terribly ugly developer mode screen.  So I tried hitting the space bar thinking that might take me more quickly to Mint than CTRL L ESC 1, but instead I crashed the entire system.  Now I'm starting all over again after re-installing Chrome OS because I had removed Chrome OS while installing Mint.  ::)

Not a glorious tale, I know, but at least I now know I can to it.  Would you be surprised if I said I genuinely believe now that these Chromebooks are best suited for Chrome OS and ONLY Chrome OS?  Why do I say this?  Firstly because it's easy to crash the entire system, and secondly because you pretty much have to run a gauntlet in order to create a set up to boot into legacy mode.   The gauntlet I ran culminated shortly after wrote and entered "If this bricks my peppy, on my head be it!"

On my head be it?  :-\

How poetic!  :)

You really need to read up on these things perknh .. there's seabios, and sommat to do with a screw that needs removing IIRC .. I'm sure someone just posted a link somewhere.

Yep, here

I love that the C720 mainboard is codenamed "PEPPY", how fortuitous is that :)

Yes, and it's very easy to do.

Here's one of many links on how to do so:

If there is a soldered-down screw, be very careful. That bit isn't easy  :-[

Yeah, that part of a Chromebook is touchy.  Fortunately the C-720's screw isn't soldered down, but I know that area of a Chromebook is delicate.  I had wanted to replace the screw after installing Ubuntu 18.02.2, but trying to do so crashed the entire installation. ::)

I have my own tale of woes:  I continue to get the message "Not enough memory to load specified image."  when trying to install Peppermint 10 on my wife's Acer C-720 Peppy.  I've successfully installed Mint on it once and Ubuntu on it twice.  Why I get that error message when trying to install Peppermint 10, I haven't a clue -- even when using the 4G Sony flash drive.  The next time I try putting Peppermint onto it, I'll try installing Peppermint 9 in order to see if there's a difference.

The important thing to me right now is that the thing works.  Right now, knock on wood, it seems to be working fine. :)

Thanks guys.  The spark you guys lit under my feet may have helped save me a couple of hundred dollars.  Of course I still have to see how it work for mrs.perknh.  That will be the ultimate test of success here.

The video link below is what I used to install Ubuntu onto it.  This guy is terrific.

If anyone who has an Acer C-720 Peppy can figure out how to tweak this fellow's instructions in order to install Peppermint 10 onto it, and then post how they do so here...Well, that would be a lot of help for the next guy.  I think the problem I'm having with Peppermint 10 is Peppy specific.  At least that's my hunch right now.  It's takes me about an hour to complete a full installation from top to bottom.  This Chromebook thing is not like installing to a Windows computer.  There are a lot more obstacles involved when installing an Ubuntu-based distro to a Chromebook than there are when installing to an old Windows computer.

If you can get 9 installed, you may have success with PCNetSpec's upgrade to 10 process.

I had this problem with Mint and Peppermint linux but not Ubuntu on my Acer C710. I had to add mem =4G as a boot parameter (I have 4G of ram in my C710) before I could install Peppermint 10. No problem since.

The only other problem I have with some distros is that trackpad doesn't work. It was always a problem with Ubuntu until 19.04 but never a problem with Manjaro. It was a known issue which just required a couple of lines of script copied, pasted and run on the command line.

Yes, I've seen that tread.  This is all new to me, but I guess we can do that now.  Wow! :o

Thank you, MNFrozenfish.


I had this problem with Mint and Peppermint linux but not Ubuntu on my Acer C710. I had to add mem =4G as a boot parameter (I have 4G of ram in my C710) before I could install Peppermint 10. No problem since.

Okay, at least for next guy, and who knows but that next guy might well be me, how do you add mem =4G as a boot parameter after you've tried the installation options for Peppermint but have then been denied because of a memory error message?  Can you then open a terminal with CTRL + t , write in a command, and then proceed directly to the installation instructions that are just sitting there on the screen?

Brianrh, I've got a feeling your Acer C-710 isn't a whole lot different than my wife's Acer C-720.  They both have 4 Gigs of memory at the very least.  Her C-720 has an Intel processor and 16 Gigs of storage.  It's also only so-so, or spotty, in the trackpad department, but is more or less functional -- doesn't matter, though, she uses a mouse.

Thank you.

Boot to the Peppermint LiveUSB .. when you get to the screen where it offers you "Try Peppermint" and "Install Peppermint" ..  hit the "Tab" key

You'll then see some white writing at the bottom of screen that ends with
Code: [Select]
quiet splash --
instead make it end with
Code: [Select]
quiet splash mem=4G -- mem=4G
then hit Enter to continue booting.

Did it boot, and allow installation ?



If it installs but won't boot after installation don't wipe it .. come back here and ask how to apply the mem=4G kernel boot parameter to an already installed OS.

No, but this message:

Quote
Not enough memory to load specified image.
boot:

After the word boot: I've tried:

1.  boot: quiet splash mem=4G
2. boot: quiet splash mem=4G -- mem=4G
3. sudo quiet splash mem=4G
4. sudo quiet splash mem=4G -- mem=4G

I've also tried the same with chronos instead of sudo.

I then get this message:

Quote
Could not find kernel image:  sudo
or
Could not find kernel image: chronos

Thank you, PCNetSpec.

You're not supposed to replace the entire line .. just change the END bit.

Everything on that line before quiet splash remains the same.

And don't use sudo .. you're not in a terminal, you're simply editing the kernel boot line in grub to add the mem=4G boot parameter.

This C720 has got 4GB RAM right ?

Something has happened...what I get now is a well-lit, grey-black screen, but nothing more. :-\

I think the C710 only had 2G RAM when new but I expanded to 4G.

I seem to think when I originally looked into this problem I seem to remember that perhaps the quantity of RAM wasn't so important as the fact you were actually stipulating a quantity to use. It might be worth trying mem=2G or even mem=1G and see if you get the same error message.
