Re: Acer C720/C720P Chromebook

@dhead No problem! I wasn't sure if it made a difference in any case.

@scot14 Thank you! I'll wait for 3.17-rc3 or 4 then, I'm not sure of the process to apply patches myself. Everything else is working great with my system, as far as I can tell.

So the light sensor kernel module is now working. (More discussion about it back on pages 2 and 3.)

The C720 and the C720P both have product name "Peppy". Since the chromeos_laptop module looks for devices based on the product name, and it sees the name "Peppy", then it looks for a touchpad, a touchscreen and a lightsensor. These error messages are logged on the C720 when it doesn't find the touchscreen. They would also be logged on the C720P if it doesn't have a light sensor.

The test shows these messages are logged even when everything is working. Thanks!

Re: Acer C720/C720P Chromebook

@scot14

Thanks, isl29018 does gives me light, ir and proximity values ( cat /sys/bus/iio/devices/iio\:device0/ ).

I've tried blacklisting atmel_mxt_ts (via kernel command line from grub) to see if the error messages will appear and they did, so I guess I just leave it like that.

I've this proff of concept for adjusting screen luminosity to light. If someone wants to improve it...

# Screen no lower than this, in %

# minimum value to get auto-dimming, if lower it default to 10% (we don't want black screen!)
LIGHT_LEVEL=$(($MIN_BRIGHT * 10))

# devices
# reads the max ambient light from the sensor
ambient_light() {
# Raw values from 0 (dark) to 999 (bright)
        light=$(cat /sys/bus/iio/devices/iio\:device0/in_illuminance0_input)
}

# calculates the target brightness level (with cutoff)
calc_bright() {
        if [ $light -gt $LIGHT_LEVEL ]; then
                bright=$(($light / 10))
        else
                bright=$MIN_BRIGHT
        fi
}

# adjusts brightness

Re: Acer C720/C720P Chromebook

Running latest ROM from johnlewis (8/26) backlight does not show up. Seems to be confirmed issue.
https://johnlewis.ie/suspend-fixed-in-c720peppy-rom/ (read comments from johnlewis)

Running Linux-mainline 3.17rc2.

Suspend/touchpad is indeed fixed, all that is needed is to provided suspend/wakeup script for ehci (else you get kernel panic)

can't seem to get logind to handle the lidswitch suspend though (openbox). assigning suspend to powerkey works however.
it works, but if you close the lid too fast logind does not register a lid event,

Otherwise everything works great.

Re: Acer C720/C720P Chromebook

I am new to Arch, finally survived the partition hell and the /boot/ miss configuration. Got X and locale working. I am finally see the light with LXQt finally installed and configured with Xorg11. However to my surprise the trackback is not working. I did the git pull driver and ran the script.

However I get a message saying that gzip:/lib/modules/3.16.1-1-ARCH/kernel/drivers/platform/chrome/chromeos_laptop.ko.gz already exists; do you wish to overwrite (y or n)?  n
not overwritten
#>

Before I put 'y' and still got the same message. Something is telling me the modules are not being correctly delivered. Please help.

Re: Acer C720/C720P Chromebook

@ _JZA_

I would recommend using linux-chromebook from the AUR instead. It's a patched kernel with the touchpad and other fixes included. You can download prebuilt packages here. https://www.copy.com/s/yxLPq6leYvky/linux-chromebook

Just install and rebuild your grub config.

@ anyone else reading this

I just built 3.17-rc2 (with the tpm patch from linux-chromebook) and am getting somewhat similar results as meowcats. I'm not using a custom rom or anything, and if I don't use the /etc/tmpfiles.d/cros-acpi-wakeup.conf and /usr/lib/systemd/system-sleep/cros-sound-suspend.sh files described in the wiki I get a bunch of nasty looking errors that I never had on 3.16. I also cannot always get the suspend to trigger from the lid close action at all under 3.17 and have to use systemctl to initiate it sometimes, even though the action is logged by systemd-logind.

journalctl output without cros-acpi-wakeup.conf and cros-sound-suspend.sh:

And if I try to poweroff after suspending when I don't have those two files, I get a kernel panic on poweroff. It need to be both too; I've tried with just one or the other and it results in the same journal messages and a kernel panic at poweroff. Has anyone else running 3.17 seens this before?

and for posterity, journalctl after a suspend/resume cycle with the two files:

Re: Acer C720/C720P Chromebook

xvkbd & xbindkeys method doesn't work for me with some gtk apps (I've got no idea why, when using xvkbd directly from its gui it does works) like Epiphany so I decided to drop it completely and use xmodmap, not sure what will work when moving to Wayland (Gnome 3.14 release is a month from now).

Here's my .Xmodmap, it seems to work perfectly.
Notice that I can still use ALT+F4 to close windows (although CTRL+Q works for most apps) and that I mapped F5 to PrintScreen as it seems like X doesn't allow for two Super_L keys.

keycode  67 = XF86Back F1 F1 F1 F1 F1 XF86Switch_VT_1 F1 F1 XF86Switch_VT_1
keycode  68 = XF86Forward F2 F2 F2 F2 F2 XF86Switch_VT_2 F2 F2 XF86Switch_VT_2
keycode  69 = XF86Reload F3 F3 F3 F3 F3 XF86Switch_VT_3 F3 F3 XF86Switch_VT_3
keycode  70 = F11 F4 F4 F4 F4 F4 XF86Switch_VT_4
keycode  71 = Print F5 F5 F5 F5 F5 XF86Switch_VT_5 F5 F5 XF86Switch_VT_5
keycode  72 = XF86MonBrightnessDown F6 F6 F6 F6 F6 XF86Switch_VT_6 F6 F6 XF86Switch_VT_6
keycode  73 = XF86MonBrightnessUp F7 F7 F7 F7 F7 XF86Switch_VT_7 F7 F7 XF86Switch_VT_7
keycode  74 = XF86AudioMute F8 F8 F8 F8 F8 XF86Switch_VT_8 F8 F8 XF86Switch_VT_8
keycode  75 = XF86AudioLowerVolume F9 F9 F9 F9 F9 XF86Switch_VT_9 F9 F9 XF86Switch_VT_9
keycode  76 = XF86AudioRaiseVolume F10 F10 F10 F10 F10 XF86Switch_VT_10 F10 F10 XF86Switch_VT_10

Edit: I'll probably move my keymap to a custom keyboard layout, that should work also on Wayland.

Re: Acer C720/C720P Chromebook

p.s.

If you're missing keys then I found a nice how-to add a mode_switch key with xmodmap.
Again I'm not sure if this will be relevant on Wayland.

Here's for example how I get the backtick character (` or grave) back as the original key is use for toggle the drop down terminal.
My .Xmodmap

add mod1    =    Alt_L Meta_L
clear mod3
add mod3    =    Mode_switch
keysym Alt_R = Mode_switch
keycode  10 = 1 exclam grave exclam 1 exclam 1 exclam

Edit:
You might need to load the .Xmodmap after desktop as the desktop might change some of the keycode mapping.
I've got a setting in Gnome that changing the Alt_R to ISO_Level3_Shift (Gnome-Settings -> Keyboard -> Shortcut -> Typing -> Alternative Characters Key) so I need to load .Xmodmap after Gnome, I'm doing that by a simple .desktop file in ~/.config/autostart/

I've changed it slightly to make is so that it only auto sets the brightness when on battery.
It also saves the previous brightness on AC and restores that when the AC power is plugged in again.

done

EDIT: This doesn't actually  restore the previous AC_brighness value when plugged in. I've made a mistake somewhere....

Re: Acer C720/C720P Chromebook

I decided to revert to xf86-video-intel-2.99.911 to see if that will help with the "stuck on render ring" bug I'm seeing.

If anyone else that experiencing issues wants to give this a try then see the attached list of packages.
It didn't helped with Chromium freezes but since v37 I'm experiencing much more freezes, so my assumption that it isn't related, at least until I'll see the error message "stuck on render ring" or output in /sys/class/drm/card0/errors.
It also won't help with vaapi, it might be a separate issue, so you probably will want to remove Iibva-intel-driver.

glamor-egl-0.6.0-1-x86_64.pkg.tar.xz
intel-dri-10.1.4-1-x86_64.pkg.tar.xz
mesa-10.1.4-1-x86_64.pkg.tar.xz
mesa-libgl-10.1.4-1-x86_64.pkg.tar.xz
xf86-input-evdev-2.9.0-1-x86_64.pkg.tar.xz
xf86-input-synaptics-1.8.0-1-x86_64.pkg.tar.xz
xf86-video-intel-2.99.911-2-x86_64.pkg.tar.xz
xorg-server-1.15.2-1-x86_64.pkg.tar.xz

Edit: After testing it looks like downgrading doesn't help.

Re: Acer C720/C720P Chromebook

Out of the scope of this thread but just thought it worth mentioning that it's seems like 42mm NGFF SSDs starting to gain momentum, prices are a bit lower (128GB drop from 90$+ to 80$), I bet prices will equal mSata drive, Transcend and ZTC also offering drives and there's even a 256GB SSD available (Transcend MTS400).

Some updates for 3.17-rc4:
- The backlight-related stacktrace no longer shows up in dmesg / journald
- The backlight works on the Core i3 version of the C720

Re: Acer C720/C720P Chromebook

I experience random reboots while the laptop is on battery. I don't really know how to find out what's causing it. However, I suspect it's due to hardware rather than software. I've done a quick google search and evidently other people (who were using Chrome OS) have experienced the same issue.

@ scot14

Thanks for the heads up! I just finished building rc4 and the suspend errors in journald indeed went away!

@ LeaveAThousand

I definitely haven't had any random reboots myself. You should contact Acer to see if you can get it fixed/get a replacement. Might be an issue with the battery or something.

I've already voided my warranty by removing the write protect screw, so I doubt Acer will fix / replace it.

I wonder if the sept 6th post from ngharo in this thread would work?

Re: Acer C720/C720P Chromebook

Wiki page looks like a mess.

1. Any reason for the "Fix Audio" paragraph ? I don't need it with 3.17rc3.
2. "Touchpad kernel modules" can be removed when 3.17 will released, what about "Touchscreen" ?
3. Some other installation steps can be moved to the general Chromebook page as they aren't C720 specific, does anyone that got another Chromebook model can confirm
4. Why "Unbricking with Raspberry Pi" is needed to be in the ArchWiki ? the Coreboot wiki is the right place for it.

Agree with you on 3 and 4. I'd wait until 3.17 is on Arch repos before removing 1 and 2 (mine doesn't have touchscreen, so I don't know if the drivers/patches for it are included).

The chromeos_laptop module has a touchscreen patch starting with 3.17-rc1:

Is this all that's needed for the touchscreen to work?

Re: Acer C720/C720P Chromebook

I'm currently running 3.17-rc4 and i've been running since rc1. Can confirm touchpad, screen backlight, and touchscreen all working.

I'm having issues with my sound. It seems like sometimes it works and sometimes it doesn't. Sometimes the audio will work then will stop working. I'm having a really tough time tracking this one down. Anybody have similar issues?

Re: Acer C720/C720P Chromebook

I got tired from xmodmap and xbindkeys so I patched xkeyboard-config.

Changes:
* F keys mapped to the same keysyms as ChromeOS, modifiers values were not changed (for example ALT+F4 still works).
* F5 mapped to the Print keysym as I don't think mapping it to Super_L will work.
* In the basic English US layout I mapped the ALT_R to ALTGR.
* ALTGR+Arrows (up, down right, left) mapped to the same keysyms as the combo CTRL+Arrows in ChromeOS (home, end, pgup, pgdown), this doesn't works in Chromium and Firefox (for navigation, it does in text boxes) but does anywhere else.
* ALTGR+Backspace mapped to Delete (in Nautilus I also set Alt+Backspace as send to trash action).

Benefits:
* This works great with multiple keyboard layouts (xmodmap setting is purged when changing layout/language).
* No issues with Gnome apps like Epiphany and Nautilus (xbindkeys+xvkbd didn't worked).
* If you using the dropdown terminal extension in Gnome, now you can get the backtick/grave character by ALTGR+` combo with the English US layout.
* If I understand it correctly then this might also work in a Wayland Desktop (Gnome 3.14) as Wayland supports XKB (Weston 1.5.0 seems to fallback to the layouts in kbd and not use xkeyboard-config).
