Lenovo X1 Carbon – Trackpoint, Clickpad, and WiFi Issues on Lenovo X1 Carbon 2015 3rd Gen

14.0414.10hardwarelenovowireless

I have got a brand new Lenovo X1 Carbon 2015 with IPS Display which is really a great laptop. But when installing ubuntu there are some problems I have already solved and some I have not. I put this all in one questions as this might be a good reference for other users.

I have installed a fresh copy of ubuntu 14.04.02

Wifi is disconnecting

Wifi works first but is disconnecting after less than five minutes. If it disconnects it can't see the SSID anymore.

lspci | grep Wireless

04:00.0 Network controller: Intel Corporation Wireless 7265 (rev 3b)

Clickbuttons are not working at all

The Touchpad and trackpoint are working fine. The clickbuttons do not work. In some Programs they do a scroll down/scroll up.

Vertical Scrolling

After fixing the clickbuttons with psmouse proto=imps the trackpoint in combination with the middle button does no vertical scrolling

Special Keys (like Brightness)

Some keys like Volume up/down work out of the box, most don't (mute, Brightness, Wifi).

Screen Characters scrambled on 14.10

On 14.10 sometimes most characters on the screen are just simply gone or scrambled. It looks really weired.

UNRESOLVED: Trackpoint Sensitivity

With other thinkpad models you can control the sensitivity of the trackpoint with /sys/devices/platform/i8042/serio1/serio2/sensitivity

This file ist not available for me. I searched /sys/devices for a file called sensitivity without success.

Best Answer

I recently purchased an X1 Carbon 3rd generation. I fought the issues you mention plus a few more. I kept a text log of all of the fixes and post as follows -

TrackPad Buttons:

  • /etc/modprobe.d/touchpad.conf:

    options psmouse proto=imps

  • update-initramfs -u

vertical and horizontal scrolling

http://www.thinkwiki.org/wiki/How_to_configure_the_TrackPoint#Configuration_using_xinput

create /usr/share/xsessions/mouse.sh (sudo chmod +x mouse.sh) with the following content:

xinput set-prop "PS/2 Synaptics TouchPad" "Evdev Wheel Emulation" 1
xinput set-prop "PS/2 Synaptics TouchPad" "Evdev Wheel Emulation Button" 2
xinput set-prop "PS/2 Synaptics TouchPad" "Evdev Wheel Emulation Timeout" 200
xinput set-prop "PS/2 Synaptics TouchPad" "Evdev Wheel Emulation Axes" 6 7 4 5

Backlight Brightness

http://ppa.launchpad.net/indicator-brightness/ppa/ubuntu/pool/main/i/indicator-brightness/

  • /etc/default/grub:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

  • update-grub

  • sudo gedit /etc/rc.local

  • echo 167 > /sys/class/backlight/intel_backlight/brightness
