Now I see the XF86 Back/Forward/Reload, but I never set these and Idk how to unset them. Also, it doesn't seem like just an X problem, because if I switch tty where X isn't running, F1-F3 still doesn't work, but since there's no X I can't use xev. (This used to trap me into tty 4, then I found chvt)

Edit: I found xmodmap, which lets me set the keys to F1-F3, but xmodmap shows the real F1-F3 keycodes having XF86Switch_VT_1, which it won't let me set on my keycodes for some reason, and I still can't use them to switch vts yet.

When I run showkey at the console and press "back button" all the way across to "increase volume", the codes are 59, 60, 61, 62, 63, 64, 65, 66, 67, 68. Also, loadkeys can be used to set them at the console.

When you first boot into X, and run xmodmap, what is the output?

I also tried using loadkeys with: (those are my F1, 2, and 3 keycodes)

keycode 166 = F1
keycode 167 = F2
keycode 181 = F3

But that made no difference in both terminal or in X.

Edit: I just tried using xmodmap, but when I specify the same 7 keysysms as the real F1 keycode, it chops off any after 4. I can get it to 6 but any more and I end up with the first 4.

stephen@Jupiter ~ % sudo xmodmap -e "keycode 167 = F2 F2 F2 F2 F2 XF86Switch_VT_2"
stephen@Jupiter ~ % xmodmap -pke | grep 167                                       
keycode 167 = F2 F2 F2 F2 F2 XF86Switch_VT_2

#Okay up to 6 but it still doesn't let me change vts with ctrl + alt + F2

stephen@Jupiter ~ % sudo xmodmap -e "keycode 167 = F2 F2 F2 F2 F2 F2 XF86Switch_VT_2"
stephen@Jupiter ~ % xmodmap -pke | grep 167                                          
keycode 167 = F2 F2 F2 F2

Also, my F4 seems perfectly fine, giving keycode 70 which is mapped to F4 and xf86 change vt 4 4

KeyPress event, serial 37, synthetic NO, window 0x3000001,
    root 0x9b, subw 0x0, time 1710279, (-472,156), root:(122,470),
    state 0x0, keycode 70 (keysym 0xffc1, F4), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 37, synthetic NO, window 0x3000001,
    root 0x9b, subw 0x0, time 1710396, (-472,156), root:(122,470),
    state 0x0, keycode 70 (keysym 0xffc1, F4), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

Edit: Now this is really odd... On "real" F keycodes, it lets me set a 7th keysysm. And when I remove XF86Switch_VT_4 from F4, it no longer switches VT with Ctrl + Alt + F4, so despite what some people are saying that nothing impliments after 6, it actually does make a difference. I just need to figure out how to set the 7th keysysm on my F1-F3.

I have the same xmodmap output for the function keys.

If you switch to VT4 and run showkeys, what is the output for keys F1-F4? Also, if you boot into single-user mode and run showkey, is the output the same?

I got:

F1 Up: 0xe0 0xea / keycode 158

Does this help narrow down what's causing this?

Re: Acer C720/C720P Chromebook

Does palm detection works for you ?

I've tried even setting very low values for PalmMinWidth, PalmMinZ with synclient and it doesn't seem to work.

"PalmMinWidth" "integer"
          Minimum finger width at which touch is considered a palm.
          Property: "Synaptics Palm Dimensions"

"PalmMinZ" "integer"
          Minimum  finger  pressure  at  which touch is considered a palm.
          Property: "Synaptics Palm Dimensions"

Re: Acer C720/C720P Chromebook

With regards to my previous remark about VA-API it looks like I was wrong and the freeze in video playback is not C720 specific.

See
http://forum.xbmc.org/showthread.php?ti … id=1754568
https://bugs.freedesktop.org/show_bug.cgi?id=78960
https://bugs.freedesktop.org/show_bug.cgi?id=81447

The sample mkv clearly freeze the system when played via VA-API.

I also have not been able to get palm detection to work yet... As a stopgap I used the .xinitrc method detailed in the Synaptics Touchpad wiki page, and that at least gives me the desired effect. The wiki page has a link to a patch, and I might give that a try later.

And as a side note, I also haven't gotten horizontal two finger scrolling to work yet either. I tried putting 

Option "HorizTwoFingerScroll" "on"

in /etc/X11/xorg.conf.d/50-synaptics.conf and the /etc/X11/xorg.conf.d/50-cros-touchpad.conf file that the C720 wiki page suggested making, but neither seemed to get it working. I haven't tried just enabling it with synclient however to rule out some sort of configuration error, so I will try that when I get home today.

EDIT:

Applied the patch to xf86-input-synaptics and Palm detection seems to be "working". Could anyone else reading this also test it out so see if this workaround is valid?

I'm using Xfce, I just tried using glamor and tearfree (at the same time, I haven't messed with them individually yet) and X11 would crash constantly but with certain actions such as opening the clear history menu in Firefox or opening a terminal.

EDIT: I just tried both individually, it's glamor that's causing the crashes.

I wonder if this will continue to be the case with xorg-server 1.16. It seems like they've improved glamor quite a bit. Might be worth a try once it's out of staging. Meanwhile, seems like UXA might be the way to go.

Thanks, the .xinitrc method for disabling touchpad gives the desire behaviour.

On Gnome the horizontal two finger scrolling works out-of-the-box without any special settings (tested on Chromium & Epiphany)

Re: Acer C720/C720P Chromebook

After some hours of researches I have successfully managed to enable Hardware Acceleration on both Firefox and Chromium reaching approximately 60fps when streaming heavy WebGL contents.

I am going to outline the procedures I have done and I hope this is going to help someone. Btw I assume the following steps should work on pretty much most of the modern Intel and Nvidia GPUs and not just on this Chromebook.


1) Install VDPAU

# pacman -S  libvdpau-va-gl libva-intel-driver

2) Set VDPAU to be used system-wide 

# echo 'export VDPAU_DRIVER=va_gl' >> /etc/profile.d/vdpau_vaapi.sh

3) enable VDPAU to be used from the FlashPlayer plugin

# echo 'EnableLinuxHWVideoDecode=1' >> /etc/adobe/mms.cfg

* Read the Gentoo wiki to learn more about the FLashPlayer plugin configuration options
http://sources.gentoo.org/cgi-bin/viewv … es/mms.cfg

4) Export the environment variable that will enable Hardware Acceleration in Firefox (this should be set in ~/.profile, however for some reason that did not work for me and eventually I decided to set it system-wide which is not that big of a deal)

# echo 'export MOZ_USE_OMTC=1 firefox' >> /etc/environment

5) Lastly you will need to type about:config in Firefox and enable the following preferences:

layers.acceleration.force-enabled
layers.offmainthreadcomposition.enabled

6) Restart Firefox and you should now have full Hardware Acceleration enabled.

* Chromium *

1) Open Chrome and type chrome://flags/

2) Enable "Override software rendering list" and restart Chromium.

Re: Acer C720/C720P Chromebook

Ever since I have installed ArchLinux on the c720 I have been getting freezes to death with whatever kernel I have used. I have used several ones, linux-c720, the linux-mainline-chromebook kernel and lastly I am currently using the linux-chromebook 3.15.5-1 one. The result is the same, every once in awhile the system freezes to the point that I have to hard reset it.

I could't figure out what the issue might be caused from since it happens without any advice or doing any specific task. I have runt mprine heavily stressing both CPU and RAM for hours and hours and all the tests ended without errors and without the system freezing to death.

Here's the output of journalctl --since=today after having had two freezes to death. Hopefully someone can help me out to identify the nature of this issue.

It seems like it's being experienced by a few people. My guess is that it has to do with power saving options, but I haven't been able to test it properly. My logs also don't show anything useful.
By the way, thanks for the guide for HW acceleration.

Re: Acer C720/C720P Chromebook

@Latrina

Can you give a bit more information about your setup? Power management, Kernel Parameters, DE/WM, etc.?

I have been running linux-mainline-chromebook and haven't had any freezes like that. I personally use tlp with default settings, with "tpm_tis.force=1", and have not used any of the recommendations in the "Fixing suspend" section of the C720 wiki page.

Hey @SolarBoyMatt

I do use TLP as well, and here's my configuration settings http://pastie.org/9410166

As for kernel parameters and power management settings I didn't really touch anything since I am not experienced enough to mess around with kernel settings, especially on a laptop.

I am using Mate 1.8.1 as for desktop manager and yes I am using Fixing suspending recommendation settings posted on the wiki.

Here's a list of all the installed packages http://pastie.org/9410183

Disk layout 

[latrina@chromebookC720 ~]$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda3        12G  8.1G  3.0G  74% /

tmpfs           189M   28K  188M   1% /run/user/1000

I have a 2.8Gb swap partition with swappiness set to 75.

Have you been experiencing the same as well? What are you exactly referring with " My guess is that it has to do with power saving options " ?

Perhaps CPU scaling and voltage in the kernel configuration or what?

My guess was because my C720 seems to freeze whenever I let it idle (but it could be just that I leave it idling way too much tongue)

I was, but since I switched to linux-mainline-chromebook I haven't seen it as much (but I haven't been using the computer as much). One thing that I've been thinking of checking, but haven't yet is to try to SSH into the computer when this "hang" happens, just to check whether it's a full freeze or just a GPU freeze.

I am using it as a daily driver and the freeze usually occurs one or twice a day. You cannot SSH or telnet into it. It just dies..

Thanks a lot for taking the time going through my journalctl logs and identify some possible strange behaviors in the kernel logs. I will make sure I match that if the issue does occur again.

Also I have removed the

/usr/lib/systemd/system-sleep/cros-sound-suspend.sh

script since apparently 

/sys/bus/pci/drivers/ehci-pci/unbind

is missing in the system.

Btw I have a noob question though, where am I supposed to add "tpm_tis.force=1" ?

According to the c720 wiki I have added 

GRUB_CMDLINE_LINUX_DEFAULT="quiet add_efi_memmap boot=local noresume noswap i915.modeset=1 tpm_tis.force=1 tpm_tis.interrupts=0 nmi_watchdog=panic,lapic"

in 

/etc/default/grub

Is that right or do I have to add  "tpm_tis.force=1" somewhere else as well?

I do apologize for the silly question but I do rarely use Linux and never used Arch before, so I am trying to catch up with all of you guys.

Thanks

That's correct. After changing this file, you also have to run 

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

Cool thanks, and yes I did of course update the grub config file.. Did that yesterday and haven't had a freeze to death since than. Also I have ditched Chromium in favor of Chrome as I have read some people have experienced system freeze when using Chromium, and to be honest beside everything I generally feel Chrome to be snappier and more responsive than Chromium, especially when streaming flash contents. Lets hope and pray.

Re: Acer C720/C720P Chromebook

After updating arch the touchpad on my C720 no longer worked.  I tried rerunning 

./cros-haswell-modules-archlinux.sh

but it failed, endlessly failing to write items to /tmp/... because there was 'no room left on device'.  There is 12GB still unused on /dev/sda1 so I am not sure how to interpret that.

So I did a complete new install of arch from scratch, but the fresh ./cros-haswell-modules-archlinux.sh behaved exactly the same.

Suggestions?

/tmp is a ramdisk, try clearing some RAM before running the script. Although I'm not sure those scripts are still still up-to-date.
An alternative is to edit the script to use your hdd to build the modules. But clearing the RAM should work just as fine.
