touchpad

[Davi Pires Santos]

I have been trying a Chromium OS installed in a Samsung series 3 notebook, but the "live usb" of Chromium OS, don't recognize my touchpad.
The Samsung series 3 have a option to turn off the touchpad, but the ubuntu by default turn the touchpad on.
 
can someone help me?

[Santos, D. P.]

I found a existing bug in kernel 3.4.0, about touchpad, the same kernel of my chromium os build, and i think, how to update the kernel, is the same that in linux?

[Yanglei Zhao]

Hi everyone,

I have the same problem using the latest daily build by ArnoldTheBat/Hexxeh. My laptop is Toshiba mini NB205, which the chromium developer hardware list says it should work. My guess is this could be a recent issue.

Does anyone know if this can be fixed?

Hi all,

Just to be more specific, the touchpad keys (right/left mouse buttons) do work. The part that is not working is the pad part. Whenever I try to move the mouse cursor, the system thinks I'm doing consecutive clicks. I believe this is a driver issue. Anyone have any thoughts?

Thanks in advance.

I have the same issue as Yanglei Zhao  with and Acer Apire One netbook.  Just downloaded it on 12/31/12 for the first time.

[teke...@gmail.com]

  I have the same problem,do you solved it? 头大阿。。。不会编译内核..

[Yanglei Zhao]

I simply turned to Android X86 project. I put a bug report on their Google Project Hosting Issues, but they say it's not a supported touchpad.

[teke...@gmail.com]

   yes，if make touchpad or wifi work need write drives manually when build os, it's a unable work to me ...need good linux kernel configuration.

[cr os]

tekee and Yanglei,

If your touchpad driver is already in linux kernel 3.4.0, but you find it was cut by chromium os, or you can find the open source driver code, you can add it by yourself, a simple method to do that is, to build the kernel module driver out-of-tree, and then copy it to chromium OS root file system, and then insmod it. :)

But...It seems a hard work if you are not a linux developer...

Hi, cr os & tekee,

The touchpad driver should be in stock Linux kernel. Since all Linux distributions I installed does support it out-of-box. I wonder if Chromium OS cut it out and used the new open source CMT driver.

Does anyone have a hint on how to build touchpad driver? Or is there any tutorial existing? I am willing to try it out. It's just I don't know how to.

[John Novicki]

Yes, if there was a simple tutorial on how to add the driver's in, I'd also be interested.

Check out this doc on how to change the kernel configuration:
http://www.chromium.org/chromium-os/how-tos-and-troubleshooting/kernel-configuration#TOC-Make-a-change-to-the-config-

You'll need to change the kernel config to include the driver you're
trying to build. Then follow the kernel build instructions to test
your work:
http://www.chromium.org/chromium-os/how-tos-and-troubleshooting/kernel-faq#TOC-How-to-quickly-test-kernel-modifications-the-fast-way-

All of this assumes you've already followed the initial setup:
http://www.chromium.org/chromium-os/developer-guide

Hi

Try http://arnoldthebat.co.uk/wordpress/2013/01/08/how-to-get-the-touch-pad-working-in-chromium-os/

It may not work, but it fixed my Dell mini and a few others...

[teke...@gmail.com]

I boot from USB and tried the way, it works,but when I want copy the img to device,an error occurred:Kernel verification blob not found in stateful partition. I change the conf file back error still occurred.What should I do...Does the USB img is wrong..

[Yanglei Zhao]

@tekee:

That is probably not the problem of that fix. If you want to install chromium OS onto you computer, follow these instructions.

@tony:

I believe there are two major touchpad manufacturers now: ALPS and Synaptics (Cirque was bought by ALPS) (as shown in http://en.wikipedia.org/wiki/Touchpad).

So my Toshiba NB205 have an ALPS touchpad. And I definitely see both ALPS and Synaptics driver in the chromium kernel source. I think those computers still have the problem might have ALPS touchpad. I will try to figure it out on my laptop and see what works.

[Maarten]

I have the same touchpad problem on my HP Compaq nc6320 notebook (to be clear: neither the pad part nor the buttons work, I can only navigate in Chromium OS by using the keyboard). I tried both hexxeh's image as well as arnoldthebat's, and they both have the same problem. I also tried arnoldthebat's fix, to no avail.

According to the specs (http://h18000.www1.hp.com/products/quickspecs/12428_emea/12428_emea.pdf), my laptop has a Synaptics touchpad, so ALPS cannot be the problem.

Weird stuff: I downloaded a random older build of arnoldthebat (the one from 28 October), and while the touchpad did not work when I started up Chromium, I did see a mouse pointer. After applying arnoldthebat's fix, everything works fine! I have full control over my touchpad now!

[long di]

yeah...I found just change etc/X11/xorg.conf.d/50-touchpad-cmt.conf Drive"cmt" to "synaptics", synaptics touchpad can work..I don't know wireless drive whether can  change in this way...

[cr os]

wireless driver is not managed by xorg, so if there is a configure file, it must be not in /etc/X11/xorg.conf.d/ path.

[Yanglei Zhao]

Hi all,

I can confirm that it also works on ALPS touchpads. The file you need to edit is actually part of the xorg.conf. I did a Google search and find out several tutorials on how to configure Synaptics/ALPS touchpad:

http://en.gentoo-wiki.com/wiki/Synaptics_Touchpad

http://wiki.debian.org/SynapticsTouchpad

https://wiki.archlinux.org/index.php/Touchpad_Synaptics

A complete manual page of how to configure your touchpad is here:

http://www.x.org/archive/X11R7.5/doc/man/man4/synaptics.4.html

[Yanglei Zhao]

Hi all,

I have written a script to automate this process for configuring your touchpad on Chromium OS. It's available here. Hope this can save you some time.

I have tried the ALPS configuration and it's pretty good. It even supports the vertical scrolling bar and have a reasonable acceleration speed.

But I have not tested the Synaptics configuration. If you can test it and verify it works it will be awesome.

Thanks,

[Maarten]

Hi,

I can confirm that your script works for my Synaptics touchpad (or at least, it didn't break it, since my Synaptics touchpad was already working because I manually edited etc/X11/xorg.conf.d/50-touchpad-cmt.conf before).

Sadly, there are still issues with my Synaptics touchpad. The vertical scrolling bar does not work, for example, and the mouse pointer disappears frequently (though this bug could be located somewhere else, because I do not have this issue on Chromium OS builds from October and earlier). Tap-to-click doesn't work either (though I do not know if it was your inention that it should work). Acceleration speed is good though.

Hi Maarten,

I have tried to treak my xorg.conf in Chromium OS for tap-to-click and did not have any luck. But I tried this in other Linux distributions and it does work. Maybe chromium os has tweaked Xorg and it does not support it somehow.

For the scroll bar, can you try to add this to your configuration?

    Option "UpDownScrolling" "1"
    Option "CircularScrolling" "1"
    Option "CircScrollDelta" "0.1"
    Option "CircScrollTrigger" "3"
    Option "VertEdgeScroll" "on"

Especially the VertEdgeScroll option. If it works I can add it to the configuration file in the script.

[John Novicki]

Script does not work on my Asus EEE PC 1000HE, which has an Elantech touchpad.  Is there a way to add a driver for this touchpad to your script, or is that not possible?  Thanks.

[Yanglei Zhao]

Hi, apparently the Linux kernel included in the Chromium OS includes Elantech driver. can you try to do this when you are the root user and tell me the output on your chromium os?

grep -i elantech /proc/bus/input/devices;

You have to be a root user.

before the grep command, execute "sudo su" and enter password for login.

Then grep -i elantech /proc/bus/input/devices ### if you have a Elantech touchpad.

Hi all, I have enabled the script to allow Elantech touchpad have a customized configuration. If you can would you like to verify that it works? Thanks in advance.

[Maarten]

Hi Yanglei,

Sorry for my late reply, I was busy with other stuff. I tried your suggestion, but unfortunately, it did not enable the scroll bar. Actually the only things working are moving the mouse pointer with the touchpad, and clicking with the left and right button. Tapping does not work, dragging does not work, scrolling does not work, and lastly, the mouse pointer often disappears, only to reappear after I click with the left or right button. It's quite unfortunate actually, as the buggy implementation of my trackpad is about the only thing holding me back from adopting Chromium OS as my main OS. I would be eternally thankful if you, or someone else in this group, would be able to fix this!

By the way, I commented on your script on gisthub, it seems you forgot a line of code for the Elantech touchpad.

Yanglei,

Your script got the touchpad working on my HP Mini 1000 with a Synaptics touchpad. Thanks!

This touchpad has a right-edge scroll zone, and that is working. Tap-to-click does not work. A curious thing is that when you type, the mouse pointer disappears, and you need to click a button to bring it back.

Best,

Dan

[Yanglei Zhao]

@Maarten:

Thanks for your reply. I am sorry that I don't know why it won't work that way. Hopefully someone can come up with a solution. Also, thanks for finding that bug.

@Dan:

Glad the script helped. Tap-to-click was not enabled in the script for Synaptic touchpad, you probably can directly edit the file and add the following lines:

    Option      "TapButton1" "1"
This should enable tap-to-click. I think the mouse disappear after type is a feature, you might be able to configure it.

[David]

I ran the script, and it properly detected the ALPS touchpad, but there's no discernible change in speed and I can't tap to click still. Is there another step I should do?

[Yanglei Zhao]

@David: I modified the script to allow Tap to click for all models.

To test this before you install anything, you can try execute "synclient TapButton1=1" after you got root access, and go back to see if tap to click works.

For the mouse speed, you might want to change the below values directly in the console, and test the speed out, then, modify the file at /etc/X11/xorg.conf.d/50-touchpad-cmt.conf.

    synclient MinSpeed=??? # Default is 0.40
    synclient MaxSpeed=??? # Default is 0.65

    synclient AccelFactor=??? # Default is 0.030

Hope this helps.

Yanglei,

Thanks for your patience, first of all. I've re-run the script and attempted the commands that you listed to no avail. Can you break down the steps (in order) that I should attempt? I'm not sure how to edit a file in the console.

[Steve Pirk]

I think the only editor CrOS has is vi and vim (vi is a symlink to vim). Hopefully, you know how to use vim. If not, google "how to edit with vim", and you should be able to do simple edits to files.

You can use vim in the console, or in a terminal window (ctrl-alt-t will bring up a terminal in a tab).

Steve,

I've edited the file, but it won't seem to save properly. That's where i hang up.

Here's how I'm exiting, please tell me if I'm doing something wrong (I am completely ignorant with regards to command line info):

1) open the aforementioned file

2) make my edits

3) press escape, then colon

4) enter wq! (! added to overwrite)

Then I get a red error message: 

/etc/X11/xorg.conf.d/50-touchpad-cmt.conf E212: Can't open file for writing

[Mike Frysinger]

if you run `dev_install`, you should be able to install qemacs. in
the future, we might offer nano too.

[Steve Pirk]

Hi David. /etc/X11 is a system directory, so you will need to use sudo to edit any files outside of /home/chronos/user (the user's home directory).

The easiest way to do this is to type sudo su and become root before you edit the file. You will also need to change the disk to read/write instead of just read.

cd to the directory /etc/X11/xorg.conf.d and type sudo su. Change the root partition (/) to be read and write, and then use vi to edit the file:

chronos@localhost /etc/X11/xorg.conf.d $ sudo su

Password: (enter root password)

localhost xorg.conf.d # mount -o remount,rw /

(this makes the filesystem read/write)

localhost xorg.conf.d # vi 50-touchpad-cmt.conf

(make your changes and save/exit the same way you did earlier)

You will probably have to reboot for the changes to take effect

[David]

I don't know why this never occurred to me, but I ran ls to see the files in that directory. There was another file named -dell instead of -cmt. I edited that one and now my mouse is moving quickly as desired. I'm still missing tap to click, though.

Here's what I get when I attempt to run the command after getting root access:

Invalid command: TapButton

Unknown Parameter 1

When I open the file to edit, I see 

"TapButton1" "1"

"TapButton2" "3"

"TapButton3" "2"

Not sure why the last two are reversed, or if that's even relevant.

Any suggestions on that?

[Maarten van der Bent]

Hi all,

This thread got snowed under a bit, so I thought it was time for a bump. I am still using Zhao's script with some success: I can move the mouse with my touchpad, but the buttons don't work at all with recent builds.

There's two questions I have with regard to the touchpad, and since I'm not a computer scientist I find it hard to find answers for them. Maybe you could enlighten me about them, Mike?

First question: since I can make full use of my touchpad when I boot crouton within Chromium OS, the problem seems to be quite high-up at the software level (I'm not sure if I'm phrasing this correctly here...). The kernel at least does not seem to have any problem with my touchpad. Shouldn't the fact that we can't use our touchpad in Chromium OS be considered a bug then? I.e. shouldn't we file a bug report for this?

Second question: again, since the problem doesn't seem to lie very deep into the system, how difficult would it be to build a Chromium OS image with support for our touchpads?

Thanks in advance for all your replies.

Best regards,

Maarten

I'm having this issue as well, except the mouse pointer doesn't appear at all until I plug in a usb mouse.  Then I can unplug it and move the cursor with the touchpad, but not click.  I can tell it's getting click events, however, as I can open the contextual menu with my keyboard and then clicking closes it. 

[Maarten van der Bent]

Yes, to my amateur eyes it doesn't seem a difficult thing to fix, with a custom build or something. It would greatly add to the overall experience of Chromium OS. I'd love to hear some expert comments on this.

Try editing your kernel boot parameters to add psmouse.proto=imps. That's what I have to do to get my mouse to work on an Eee PC 701 with a synPS/2 touchpad. Nothing else I have tried works, but that seems to do it.

You can edit the boot parameter by modifying the boot files. The files can be modified by mounting partition 12 on your disk (sudo mount /dev/sda12 /mnt/whatever). Then go into the syslinux folder, and edit the root.A.cfg, root.B.cfg, and if you're on usb the usb.A.cfg (sudo vi root.A.cfg). Each config file has two entries, I add the psmouse.proto=imps in each.

Note that if you're building your own image you can just pass --boot_args=psmouse.proto=imps when doing a ./build_image. If this doesn't work for you, consider trying other psmouse arguments. Your problem may not be xorg based...

Did you have to jump though any hoops to get Chromium-OS working on a
701? And was that an install or running from USB?

This might be old but ive been trying to figure out how to mount the partition to edit the files. I have a sony netbook with the hexxeh build installed. I'm able to move the touchpad but cannot click on anything. I'm new to linux but I have found the locations of the files just do not know how to edit. Thank you

sudo mount -o remount,rw /

That will remount your root filesystem for updates. Just make sure the image doesn't have rootfs verification enabled.

I have had the same problem and I am looking for a device and drive manager for chromium and then you will be able to re-enable your touch pad till then you eill have to use a USB mouse.
