It's not working for me either, and I do have xf86-input-synaptics installed. Has anyone modified the cros-haswell-modules.sh script for 3.15 kernel compatibility? That seemed like a much more elegant solution to me.

Hi tidux, the linux-c720 and linux-chromebook are no ordinary packages, they are complete kernels that you need to boot into to use, are you doing that? They are definitely a more elegant way than hacking at a currently installed kernel like that script does.

Good point, maybe I should have mentioned this. But it's not only hacking the current kernel. linux-c720 is based on Linux 3.16 rc1.

With linux-c720 the touchpad works for me but suspend/resume and the touchscreen don't. Still have to figure out a way to solve this.

I can't comment on linux-c720 but resume should work with my linux-chromebook with tpm_tis.force=1. Touchscreen should work with my linux-mainline-chromebook, that I mentioned a few posts back, I haven't put it on the AUR yet, probably will for rc2.

I had this happen several times on HP14 Falco while dual-booting ubuntu and chromebook. In my case, the cause appeared to be running the battery completely down. Is it possible that you had some sort of power disruption?
In the past, I reset by going into chrome. Now that I'm single-booting into Arch, this kinda terrifies me. I wonder if it's possible to boot the Arch install media (2013-10-01) and *then* arch-chroot into the chrome recovery media to do the recovery.
Also, maybe the following programs can be run under Arch (and therefore be added to the install media image for a quick restore)?
# chromeos-firmwareupdate --sb_extract /tmp
# flashrom -w /tmp/bios.bin -i RW_LEGACY
R.e. power, I've also had the "battery stops charging" problem. No idea what caused it, and it magically reset/fixed itself after a week or so when the battery finally drained to absolute zero. In short, some of the firmware on these seems pretty shaky.
I tried re flashing Seabios. I'm wondering if my write protect screw has come loose and is causing the reboot. I tend to pick it up with one hand on the side that the screw is on. I've now lost my system instal for the 4th time though so I'll be using crouton from now on.
In my case there is now way to get to the install media, if I could i would also be able to boot from the hard disk and there would be no problem. My issue isn't a corrupt bios, dev_boot_legacy/usb get reset to =0 instead of =1.

Right. Duh.
One difference between the models is that HP14 Falco doesn't have a write protect screw, just a keyboard combo, which I don't think I ever hit other than the first time I turned on dev-mode. So I've encountered the same issue, apparently independently. But it seems that a hard/power-driven reboot is a common feature (I regularly soft-reboot with reload-power 2-finger salute and never encounter this issue).

My understanding was that *non*-legacy, default boot method for the chromebook used UEFI. I tried to get get arch to boot on this machine via native UEFI with no luck. I don't really understand what the default boot process actually is. What is handling the "Disk does not contain Chrome" message, and booting the recovery image, and is there any way to hijack it??

I can't confirm this. I installed your package, updated grub to boot the new kernel and set tpm_tis.force=1. Still doesn't suspend. Since I'm not really used to all this systemd stuff, I have to figure out where to get useful debug info.

kschwarz · 2014-06-22 10:13:09

@parchedas sorry for my late respond. I have tried your mainline kernel and since my webcam is not recognized anymore. My touchscreen works partly but lost its click abilaty and suspend works as it should.

I haven't been able to get either linux-c720 nor linux-chomebook repos to work properly for me (linux-c720 stalls on boot saying something about wifi-menu, and linux-chromebook runs out of space while compiling).

So I've created a github repo that patches up the current kernel to add touchpad and touchscreen support. It adds a patch to replace patches 3078481 and 3078491, and includes a modified script which previously worked for the 3.14 kernel.

https://github.com/masmullin2000/arch-c720p.git

Unlike the previous iterations of the patching script, this does not use the tmp directory to download and compile, so you'll have to clean up for yourself.

Tested on 3.15.1

usage
git clone https://github.com/masmullin2000/arch-c720p.git
cd arch-c720p.git
sudo sh ./touch.sh

Confirmed working for me on 3.15.1. Thank you very much for sharing this. I wasn't able to get linux-c720 (aur) working for me either, and with your script, my touchpad is back in business Are you planning to keep it up to date in future releases of the stable kernels?

Edit: except the backlight-fix which doesn't seem to be included; the backlight can't be manipulated with xorg-backlight.

You're welcome. I had to create the patch and update the script for my own purposes, and figured I'd be a bit of a cock if I didn't share. If I ever have to make changes to get my computer to work, I'll for sure upload them to the github.

kschwarz · 2014-06-22 22:51:59

@masmullin your patch is working for me too just the backlight doesn't.

DoctorSamulus · 2014-06-23 01:44:54

@masmullin: Does this work for the non touchscreen version of the C720 too? I can't build linux-c720 either, I'm on i686, kernel 3.15.1-1.

Try now. I've added the backlight patch originally found here (https://bugs.freedesktop.org/attachment.cgi?id=101223). It allows me to toggle the brightness on gnome (I have no idea what app does that though).

@DoctorSamulus: I don't know if it will work for a 686 c720. Please let me know if it does.

DoctorSamulus · 2014-06-23 06:29:37

I installed the latest version. It works great on the i686 C720. Backlight too thanks.

Try rc2, rc1 had a usb autosuspend bug that affect the webcam, although I did not actually check if it worked or not, mine definitely works now with rc2 anyway. How is your clickabililty @pegasus21?

Hmm, interesting, just to confirm

cat /sys/module/tpm_tis/parameters/force

returns Y? Are you 32 or 64bit?

parchedas · 2014-06-23 22:04:41

I have added linux-mainline-chromebook to the AUR for anyone who is interested. It adds touchscreen support for c720P

I'll test it once I get home.

As for the webcam, I did not test it previously hence I do not know if it worked either.

pegasus21 · 2014-06-24 14:27:24

Ok, I've tested the things below.

Brightness - Ok
Suspend - Works fine even more than twice and able to shutdown/restart
Touchscreen - Initially working fine but after awhile, not working. Seems similar to r1 kernel. Tried to reload cyapa module but to no avail. A reboot solves it but I suspect only till it acts up again.
Touchpad - Ok
Camera - No idea how to get it working but it's detected and guvcview turns on the led indicator
Sound - Ok
Wifi - Ok
Bluetooth - Ok

I'm seeing a lot of ongoing messages in dmesg which I assume is related to the touchscreen since it's not working at this stage.

It looks like I'm getting much less freezes (well nothing, but just changed to it today) with UXA.

I've tried SNA (allot of freezes) Glamor (much less) with linux-chromebook 3.15.1 and with both of them I'm still getting freezes, I don't have to do something special, just run the desktop.

Is it just me ?

Anyone recognize a related Intel/DRM open issue at freedesktop.org ?

Looks like a bug http://permalink.gmane.org/gmane.linux.network/321063 hopefully they'll fix it by rc3.

Yeah that's the touchscreen, so you only see those once it has stopped working, correct?

That's right. The i2c messages only appear once the touchscreen isn't working.

I'm working on a permanent patch for the backlight issue described at https://bugs.freedesktop.org/show_bug.cgi?id=79813

The patch works by creating an exception for the Acer C720, Dell 11, HP 14, and Toshiba CB35 Chromebooks. I'd appreciate anyone testing it and reporting back here with which machine it worked/failed on.

Also, if you contact me directly with your name, email, and which machine you have (either through the bug report or the forum here) before I submit the patch to the intel mailing list, I'll include you as Tested-by.

Patch against 3.16-rc2: https://bugs.freedesktop.org/attachment.cgi?id=101813

Thanks!
