Hi,

I have trouble getting the wifi to run.
Do I have to install a driver or firmware to get it running?
I think this would be mentioned in the great wiki page, but it isn't so I'm not sure, if this is the correct way.

Thanks for your time!

The Wifi module should work out of the box. The driver (ath9k) is part of the kernel. Did you install iw and wpa_supplicant? Give it a try:
# pacman -S iw wpa_supplicant

If you are using bluetooth simultaneously, the performance might degrade a little. To make things better, enable bluetooth coexistence on the module.

Re: Acer C720/C720P Chromebook

Oh man, I can't believe it.
After your response I tried to connect another time to have some logs, and now it worked.
before I tried with wpa_passphrase, wpa_supplicant and dhcpcd and netctl, now I tried wifi-menu it this just works.
So perhaps this helps someone else.

But anyway, thank you very much for your fast response.

Re: Acer C720/C720P Chromebook

Allright, now I have another issue:
When I run pacstrap it outputs this line very often and than quit:

    error: could not open file /mnt/var/cache/pacman/pkg/vi-1:050325-3-x86_64.pkg.tar.xz.part: Invalid argument

I chose fat as filesystem format as suggested in the wiki, but I read somewhere else, that fat doesn't support : .
Is this the reason for the problem? Should I then switch to another filesystem format?

I also checked the usb drive for errors and checked the md5sum and sha1sum of the image, all this seemed good.

Huh? I don't think the wiki suggests FAT anywhere for installatioin (except for creating a UEFI partition, which we are not doing). Where did you see this?
You should use ext4, btrfs or another linux fs.

Oops, awkward.
I don't know where I got that, perhaps I confused it with the DOS partition table?

Thank you again.

Re: Acer C720/C720P Chromebook

Me again ^^

I'm using an optimized keyboard layout where the capslock key is actually useful.
But now the capslock is not doing what it should, but is cycling through the ttys, any idea on how to deactivate that?

Re: Acer C720/C720P Chromebook

You have to edit the keyboard layout. Actually, it might be better to use xmodmap or something like that instead of changing the layout, but you should probably ask this in a different thread as it's not completely related to the C720. In the C720, the key above the L_Shift is a Super key

Re: Acer C720/C720P Chromebook

Hi I've had suspend set up as per the wiki instructions for some time now, but I am noticing that when I close the lid, the laptop suspends and then resumes again with it closed. Sometimes when the laptop is plugged in to power, it periodically suspends and resumes with the lid closed.

Any ideas what I can do to solve this issue?

Re: Acer C720/C720P Chromebook

Hi,
I also have problems with suspend.
I did it like it is proposed in the wiki and when I close the lid, it suspends and when I open it again, it resumes, but then freezes.

Did we do something wrong in following the instructions in the wiki, or is there another problem?

Some pointers for explanations of what is happening would be nice, as it is hard to extract the useful information from this thread.

@timjefferies @foolius: Did you make the file (/usr/lib/systemd/system-sleep/cros-sound-suspend.sh) executable? That's really important. Also make sure you've re-built grub.cfg after changing grub's parameters

Ah, I think I forgot to set the one file executable. Thanks for the answer.

So now XFCE freezes directly when I start it like before after resuming sad

Try this script. If it works, you can add it to the wiki: script

Before, XFCE worked fine. When I closed the lid the laptop suspended. When I opened it again, the desktop came up looking like before I closed the lid but I couldn't do anything. The mouse cursor didn't move and keypushes didn't do anything.
Now when I startup XFCE with startx it is frozen at once and I can't do anything.

Thank you for your help, I hope my explanations are clear.

Re: Acer C720/C720P Chromebook

masmullin,

running the script you have posted gave me a 404 when downloading the kernel source from kernel.org (it's looking for linux-3.14.0.tar.gz instead of linux-3.14.tar.gz).  Easy enough fix on my end, just letting anyone know who's having problems.

How did you fix it?  this line "kernver='3.14'"  should make it so that wget doesnt look for the .0, which was included in Anatin's original script.

I just hardcoded it to 3.14 like you said.  The original line set the variable to uname -r | cut -d'-' -f 1


Looks like I had the old version and you had already fixed that.  My appologies.

Haha, thank you for giving me credit. The fix is really ugly though tongue
For some reason, kernel.org prefers to omit the .0 in the filenames. I've tried using some clever tricks, but in the end, it was just easier to hard-code it.
I'm surprised that we still need to add any patches at all, does anyone have any idea on when will all these patches be merged (or if they'll be merged at all)?
In my script, I've tried applying each patch individually, and removed the ones that seemed to already be merged and the ones that didn't apply correctly. I didn't think it'd work since I didn't apply the patches that failed, but I'm glad I was wrong.

Re: Acer C720/C720P Chromebook

Suspend stopped working for me recently. Maybe it's because of the new kernel. Suspend worked for me before.

I've followed the wiki steps exactly.

Re: Acer C720/C720P Chromebook

OK, so I was kind of stupid.
The problem was, that also for me the touchpad didn't work.
I used the script (thanks for that!) and now XFCE works again.
But suspend still doesn't work. The screen goes black and the light blinks in red, but when I turn it on again, it just boots normally.
