Boot into Peppermint

run:
Code: [Select]
gksudo xed /etc/default/grub
find the line
Code: [Select]
GRUB_TIMEOUT_STYLE=hidden
and change it to EITHER:-
Code: [Select]
GRUB_TIMEOUT_STYLE=menu
OR:-
Code: [Select]
# GRUB_TIMEOUT_STYLE=hidden
SAVE the file and exit the text editor.

Back in the terminal run:

Try choosing option #1 and immediately hit the Esc key .. did GRUB display ?

PCNetSpec, if I installed Ubuntu 18,04.2, or Mint Cinnamon 19.1, on mrs.perknh's Chromebook again, while also running two rounds of inxi -Fz, or any other commands, on Peppermint first, and the other distribution of your choice after, would the comparison of the two sets of commands help you determine what Ubuntu or Mint are doing differently than us so that they don't require a boot parameter?  Might doing some reverse engineering help you here?

All I know is that this Chromebook is not like a normal Windows computer.  It is very, very, particular, and intentionally so, I believe.

Here's Peppermint's inxi -Fz:

If you're okay with reinstalling (if this breaks booting), first try this...

Boot into Peppermint (on the hard drive)

run:
Code: [Select]
gksudo xed /etc/default/grub
find the line
Code: [Select]
GRUB_CMDLINE_LINUX="mem=1G"
and change it to
Code: [Select]
GRUB_CMDLINE_LINUX=""
SAVE the file and exit the text editor

Back in the terminal run:
Code: [Select]
sudo update-grub
See if you can you still boot now ?

If the machine still boots, post the output from:
Code: [Select]
free -m

I had to add a xed before your command, and I had to reboot, but here are the results:

That is terrific.  Assuming Brianrh has the same memory issue on his Acer C-710, he should now be able to do the same procedure in order to free up the memory on his Chromebook too. ;)

Thank you so much. :)

Great stuff .. so it seems the mem=nG kernel boot parameter **IS** only necessary for the installation, and can be removed post install :)

Fixed the command above.

[EDIT]

Are you ever likely to use hibernate ? .. if so we'll likely have to expand your swapfile size now, but on such a small drive I wouldn't bother because it'll eat a quarter of the drive.

Here's free -m from Peppermint 10 after full installation.  Yeah, I reinstalled again, but this time with Peppermint 10.

Code: [Select]
ecuaperk@peppy ~ $ free -m
              total        used        free      shared  buff/cache   available
Mem:           3885         263        3181          37         440        3365
Swap:           707           0         707
ecuaperk@peppy ~ $

And here's free -m from Peppermint 9 after PCNetSpec salvaged its memory, but before I'd removed a few packages and personalized the distro:

Code: [Select]
ecuaperk@peppy ~ $ free -m
              total        used        free      shared  buff/cache   available
Mem:           3885         475        2735          81         675        3108
Swap:           707           0         707
ecuaperk@peppy ~ $

Those differences aside, my conclusion is Peppermint 10 is generally better on resources than Peppermint 9 -- which is okay by me!  ;)

Are you ever likely to use hibernate ? .. if so we'll likely have to expand your swapfile size now, but on such a small drive I wouldn't bother because it'll eat a quarter of the drive.

No, never.  I mean I'm probably going to set the power button to suspend upon press, but I don't remember us ever regularly using hibernate.  I hadn't even given it a thought.

Thank you, PCNetSpec.  I've now synced mrs.perknh's new "Pepperbook" to her Chrome account.  I believe mrs.perknh will now be able to continue with Peppermint 10 here without missing a beat! :)

Do you still have the trackpad issue perknh?

Unfortunately, yes.  This morning the cursor worked pretty well for the most part.  Right now, in the afternoon here, after booting up, the cursor isn't moving at all.  Yesterday, with Peppermint 9, the reverse was true.  First the cursor froze on the screen with Peppermint 9, but then worked relatively well for the most part thereafter.  (Right now, after writing this post and then rereading it,the cursor works for a spell on Peppermint 10 and then freezes, works again for a spell, and then freezes.)

Now it's hard to say if this is more of a hardware issue or a software issue.  After all, this is an old Chromebook.  I suspect it's probably a little of both -- not sure. :-\

Anyway, mrs.perknh has a mouse that I'm sure will work just fine.  I say that because my mouse works just fine with it. ;)

Should be interesting to see what happens when we're running kernel 5.0 by the end of the summer.  I know 5 is just a number, but I've heard 5 will offer much more hardware support than the 4 series.  I know this will either be hit or miss, so we'll see.

Thanks for asking.  I forgot all about the trackpad because I hardly ever use it.

Until the Ubuntu 19.04 I have always had to carry out tweak to get the touchpad to work on my C710 with Ubuntu based distros. With Peppermint 10 I also had to run the couple of lines of script in the terminal as explained :

https://www.reddit.com/r/chrubuntu/comments/34d6qs/help_acer_c710_touchpad_support_with_ubuntu_1504/

However I've never had intermittent operation of the touchpad so that may be a completely different issue.

However I've never had intermittent operation of the touchpad so that may be a completely different issue.

Got curious this morning and decided to boot up the Chromebook and run those two commands.  So I booted it up without the mouse, and to my surprise, the trackpad is working nearly perfectly again this morning. :o

But because of this change, I cannot now justify doing anything to the Chromebook. However, since I don't know what to make of this with this Jeckell and Hyde behavior, here's what I'm going to do:  I'm going to put a reminder on the calendar to check how the Acer C-720's trackpad is doing during the first week of September.  From what I'm gathering, Ubuntu 19.04 is the first Ubuntu distro on which your Chromebooks trackpad worked correctly.  I suspect that's because it's running the 5.0 kernel.  Yesterday Peppermint/Ubuntu 18.04.2  received an upgrade to its kernel, and I want to see if this trackpad issue is going to continue to improve as the kernel keeps upgrading itself.

Now, Brianrh, were you now able to free up the memory on your Chromebook running PCNetSpec's commands from Sunday?  That was a major game-changer for me with this old Acer C-720.  (I'm assuming your Chromebook had the same memory issue after installation that my wife's Chromebook was having .)

Update from later in the morning:

I turned on the Chromebook without a mouse, and played with the trackpad.  This time the cursor froze on me again like it did yesterday.  Ran the two commands just to see what would happen, but nothing happened.   The cursor still freezes on he screen with a jump here and there. 

However I've never had intermittent operation of the touchpad so that may be a completely different issue.

I guess that command works on a different issue. 

Thank you, Brianrh.  That was certainly worth a try. ;)

The only time I have had to do a memory setting tweak was when initially installing Linux Mint and recently Peppermint 10 from a Live USB. From then on booting from the harddrive no problem and no setting required. However I have always had 4Gb of RAM and an 120Gb SSD fitted since upgrading the C710 after I bought from second hand on Ebay, so perhaps this makes a difference.

I've installed Manjaro successfully at least a couple times with older kernel versions than recent Ubuntu ones, and never had a touchpad problem. So I think it must be down to the blacklisting Ubuntu did to the kernel and doesn't do now, referring to the Reddit article, that causes the problem.
