trackpoint causes scrolling not clicking for ThinkPad X1 Carbon 3rd Gen.

may as well paste the other things I've been keeping track of...
(from: https://plus.google.com/+JonathanZacsh/posts/J2RKNgx5vws)

1) Works: *controlling screen brightness* http://itsfoss.com/fix-brightness-ubuntu-1310/
2) Works: *black screen* at installer: http://askubuntu.com/a/162076 tl;dr grub command line, add 'nomodeset'
3) causes touch-screen not to work: *acpi_osi=Linux* to your GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub

*Still broken*
1) Trackpoint's mouse-buttons (joystick is fine)

Hello jzacsh, can you post the output of following command, open a terminal and type: xinput

Hello,
I am having the same issue with X1 Carbon 3rd generation and Linux Mint 17.1 Rebecca.
This is my xinput:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Lenovo Laser Wireless Mouse id=9 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Video Bus id=7 [slave keyboard (3)]
    ↳ Sleep Button id=8 [slave keyboard (3)]
    ↳ Integrated Camera id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

In this configuration, the touchpad works fine, but the trackpoint pointer works, but the trackpoint left/right buttons act as 'up/down' arrow buttons, and the middle button does nothing.

After doing:

sudo rmmod psmouse
sudo modprobe psmouse proto=imps

The xinput now reads:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Lenovo Laser Wireless Mouse id=9 [slave pointer (2)]
⎜ ↳ PS/2 Synaptics TouchPad id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Video Bus id=7 [slave keyboard (3)]
    ↳ Sleep Button id=8 [slave keyboard (3)]
    ↳ Integrated Camera id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

In this configuration, the trackpoint buttons work properly (left/right, and the middle button can be configured too, including the wheel). However in this configuration, it is impossible to disable the touchpad, as it seems that PS/2 Synaptics TouchPad configurations apply to both the trackpoint and the touchpad.

Finally I can also do:

sudo rmmod psmouse
sudo modprobe psmouse proto=bare

With xinput now reading:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Lenovo Laser Wireless Mouse id=9 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Video Bus id=7 [slave keyboard (3)]
    ↳ Sleep Button id=8 [slave keyboard (3)]
    ↳ Integrated Camera id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

Again this resurecs the trackpoint buttons but has the same issue that the touchpad cannot be disabled.

Please let me know if I can give any more ouput that would help debug this issue.

Hi,
A workaround to have the trackpoint buttons working AND the touchpad disabled can be found here:
https://bugs.freedesktop.org/show_bug.cgi?id=88609#c9

The idea is to use proto=imps (as I commented in my previous post) but if you also want the touchpad disabled, to do that in the BIOS settings, by pressng F1 at bootup, and disabling the touchpad in the BIOS menu.

- joydidier, thanks! I also have my trackpoint's mouse buttons currently causing up/down scroll behavior. I will try out your solution in comment #4 in a few hours.

- kaxing, let me know if its still useful to see my `xinput`

(probably worth noting: I am very unfamiliar with how to read xinput's output and make sense of these different options)

joydidier, can you clarify on #1 below? can either of you shed some light one what i'm doing wrong with #2? Thanks!

k, tried to pretty confused at the moment:
1) doing the following gets me working trackpoint, but idk (despite the freedesktop thread) how to disable touchpad via BIOS:
  sudo rmmod psmouse && sudo modprobe psmouse proto=imps
2) despite #1 working, I can't make it stick beyond a boot (all pasties below related to this point)

$ cat /etc/modules
lp
rtc

$ cat /etc/modules-load.d/psmouse.conf
psmouse proto=imps

$ cat /etc/modprobe.d/psmouse.conf # seems like maybe i should remove this, given modules-load.d file?
options psmouse proto=imps

$ xinput

k, #2 solved by updating grub in these steps:
a) added psmouse.proto=imps to grub, per https://bugs.freedesktop.org/show_bug.cgi?id=88609#c10 ie:
   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash psmouse.proto=imps" # acpi_osi=Linux
b) sudo update-grub # then reboot

of course, #1 is still a problem :P (ie: trying to type these comments with my trackpad still enabled is pretty difficult)

joydidier, Thank you for the anwser!

Hey jzacsh, I was just wondering if the device are being correctly recognize.
If joydidier's workaround this should be fine.
Thank you for asking this question, too.

This information will be helpful for future certification.
Thank you both again!

tl;dr how does one disable the trackpad via the BIOS? (note I do not have windows installed on this machine)

kaxing, are you saying that in response to issue #1 or issue #2 from the top of comment #6? I can see how it would address comment #2, but as you can see I solved that moments later...

@jzacsh sorry, I didn't refresh my page, and yes, i saw those information.

And for your question about turn off the trackpad, ususally it won't be an option to disable the trackpad(as far as I know)

In your case you can disable touchpad by following command:

xinput set-prop 'SynPS/2 Synaptics TouchPad' "Device Enabled" 0

and Enable:

xinput set-prop 'SynPS/2 Synaptics TouchPad' "Device Enabled" 1

Personally i'm using touchpad-indicator, can be found in this ppa:
https://launchpad.net/~atareao/+archive/ubuntu/atareao

Hope this help!

Note: Ubuntu software update just caused me to no longer be able to disable tap-to-click (where I had that disabled previously). I don't know what happened with this update now my machine is really quite unusable.

@joydidier if you're still watching this bug, can you respond? I'd love if you could elaborate in how-to words your comment #4

Hi,
What do you need elaboration on?

hey joydidier!
I'm trying to follow along on the freedesktop thread you linked to, can you explain how to disable touchpad via BIOS?

If I read the linked email by Matt Wislon correctly, its two steps:
1) sudo rmmod psmouse && sudo modprobe psmouse proto=imps
2) disable touchpad via BIOS --- this is what I can't figure out how to do
