Hi, I have a Chromebook C720p 2go.

i do this command without remove the write protect screw
# set_gbb_flags.sh 0×489

but seabios seems to work.

this command :
#crosssystem

give this result at line
ecfw_act = RW

Its wrong ? or it's ok ?

Does it continue to work after reboot? Maybe YMMV, but with me this caused to SeaBIOS to become corrupted.

mum1989 · 2014-06-27 20:42:54

yes, no problem at this moment.

And how to recover Seabios ?

this command it's ok ? http://www.chromium.org/chromium-os/dev … esn-t-Work
You can safely reset the copy of SeaBIOS in your flash by running (as root):
# chromeos-firmwareupdate --sb_extract /tmp
# flashrom -w /tmp/bios.bin -i RW_LEGACY

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!

https://github.com/masmullin2000/arch-c720p is using scot14's patch now.

Cool, what command did you use? Was it:

# hwclock --systohc --utc

I'm also compiling a "tutorial" style guide to install Arch on the C720 in my blog. Since I've installed mine a while ago, I need to update the steps to take.

Guys is anybody having issues with mapping the hotkeys on the C720? more specifically the F9 and F10 (volume up / down ) keys.

I followed the guide exactly as according the wiki regarding the hotkeys mapping section, the problem is that I can't get the F9 and F10 (volume up / down ) keys to do what they are supposed to do, they only works to unmute. I have had the same result with either Sxhkd and xbindkeys.

Any idea?

Thanks

timedatectl was used to setup time, when pacstrap finished i started using utc again, i think it was like that :-P

So you entered the time manually? e.g.

# timedatectl set-time "yyyy-MM-dd hh:mm:ss"

I wonder if running

ntpd -qg

would work as well. Maybe we should put that in the wiki.

Yes thats correct, hwclock showed year 2055 on all formats before i set that :-)

Guys another question regarding keys mapping. Is there a way to map the poweron button to call the restart / suspend / logoff panel anytime that it gets pressed? I am using cinnamon as DE.

Thanks

Having some issues getting suspend/resume to work properly on my C720P 4GB, using the linux-c720 kernel found in the AUR.
I also followed the steps mentioned on the wiki page for getting suspend to work.
Suspending on lid close only seems to randomly work, suspending using systemctl suspend does work reliably.
The problem in both situations is that it when it does suspend, it instantly resumes. Sound/touchpad/keyboard do work after resuming.

So what is the current recommended way to get the touchpad to work? Tons of conflicting information. linux-c720 works, it doesn't work. You should use this patch or this patch. I'm not sure what I need to do.

If I try linux-c720 is there anything I need to do more than install it from AUR?

I can tell you my experience with 3.16.0-rc3-c720 and so far so good. Touchpad works, suspension and resume works too, although as according to the dev the blacklight module might die, however this didn't happen to me so far.

Once compiled and installed the kernel, you will have to re generate another ramdisk for the newly installed kernel, and that would be

# mkinitcpio -p linux-c720

and lastly you will need to regenerate the grub configuration

# grub-mkconfig -o /boot/grub/grub.cfg

My advise is try it urself, if for some reason it doesn't work for you, report the problem you are facing and revert back to stock.

Later.

I can't get it to build, something about 'no space left on device'. Does this have anything to do with my partioning? I have 1 MB set aside as a BIOS boot partition, the remaining part of the disk as one big /, and then there is an additional 1007K of free space. If this is relevant, what is the right way to allocate partions?

That's what confuses me is the wide variety of reports on the same piece of hardware. No single approach seems to work for everyone.

Have you set a specific BUILDDIR in /etc/makepkg.conf ? If yes make sure that this one isn't running out of space.

If not, make sure the partition where you are building the kernel isn't running out of space.

Additionally, cleaning up /tmp might be a good idea.

I changed TMPDIR in /etc/yaourt to a folder in my home directory and I still am getting "no space" errors when I try to build linux-c720.

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

This worked for me. Great job.

I hope a future kernel update makes this all unecessary. This seems like an amazing arch machine for the money.

Having some issues getting suspend/resume to work properly on my C720P 4GB, using the linux-c720 kernel found in the AUR.
I also followed the steps mentioned on the wiki page for getting suspend to work.
Suspending on lid close only seems to randomly work, suspending using systemctl suspend does work reliably.
The problem in both situations is that it when it does suspend, it instantly resumes. Sound/touchpad/keyboard do work after resuming.
dmesg:

Been trying to get this to work for the past couple of hours, any help would be appreciated. Thanks.

Made some slight progress on this.
I've gotten manually suspending/resuming from a terminal to work consistently with the "linux-mainline-chromebook" package from the AUR.

Suspending on lid close only works after manually suspending one time. After manually suspending once, suspending/resuming on lid close/open works as it should.
Anyone have an idea what might be causing this?

Update on this. Worked mostly okay for several minutes (except when I closed and reopened the lid, the touchpad stopped working - probably a suspend issue mentioned in the wiki). However, after a reboot my touchpad has stopped working entirely. Specifically, I heard what sounded almost like a fuse popping, so I'm concerned something might have burned out, but I can't tell because my entire experience with the touchpad has been flaky. Edit: touchpad works fine after wiping arch and reinstalling chromeos. Still no solution.

Hard to beat for the money, but if anyone is considering getting this machine to install arch I might wait until some of these little issues are resolved.

Chromebook-mainline in AUR solved most of my module problems and problems, now its just some basic app configs and TLP or some alternative to get awsome battery life left to do :-)

Sorry to hear about your touchpad worries. I suggest you immediately put chromeOS back on your c720 and see how that is running (there is a method to dual boot btw... its really handy). If the touchpad is still broken, you should be able to make a warrenty claim (I'd suggest not mentioning that you were running linux). If the touchpad is good, give arch another try, but do the suspend disabling stuff that's listed on the wiki page. The kernel modules compiled via that github are *only* to work on the touchpad/touchscreen and backlight.

I didn't write any of these patches, nor did I write the script. I'm just a guy who wants my c720 to work, so I fiddled with the script a bit to get it working for me and figured I'd be a jerk if I didn't share. I'm actually kind of worried that I'm violating copyright, so please give both kudos and blame to the original author... whomever that is (I have absolutely no idea).

As for things getting easier with newer kernels, the opposite is true. Bitrot is causing some of these patches to not apply well; which is why I had to fiddle with the script. and the touchscreen patch doesn't apply at all on 3.16 due to many, many advances. I have a 3.16 branch which grabs a kernel with advances rolled back for the atmel_mxt_ts.c file in order to apply the touchscreen patch... but this is REALLY sub-optimal.

I have no idea why these patches aren't going into Linus' kernel main. But I'm pretty concerned as many of these patches are from october 2013, so I figure they should be in by now.
