lenovo z470 keyboard gets stuck

Question

I installed ubuntu 13.04 64bit on my lenovo idea pad z470. My problem is when I press any of the hardware one-touch short-cut keys for volume control, heat control, etc., my keyboard gets stuck, and I'm no more able to type anything there on.

Answer 1

I had the same problem, I was close to commit suicide, there was no solution, but ...

There's a simple "fix" :D

For UBUNTU 13.10:

1. Open your Terminal.
2. $ sudo nano /lib/udev/hwdb.d/60-keyboard.hwdb
3. In nano editor look for "lenovo" section (CTRL + w).

4. Add this section (Copy and Paste):

   # IdeaPad Z470
   keyboard:dmi:bvn*:bvr*:svnLENOVO*:pn*IdeaPad*Z470*:pvr*
    KEYBOARD_KEY_a0=!mute
    KEYBOARD_KEY_ae=!volumedown
    KEYBOARD_KEY_b0=!volumeup
   

5. Save changes and exit nano.

6. sudo udevadm hwdb --update
7. restart.

For UBUNTU 12.04 and 13.04:

1. $ sudo nano /lib/udev/rules.d/95-keyboard-force-release.rules

2. Add the following line at the end of the file (but before the LABEL="force_release_end" line.)

   ENV{DMI_VENDOR}=="LENOVO", ATTR{[dmi/id]product_name}=="IdeaPad Z470", RUN+="keyboard-force-release.sh $devpath common-volume-keys"
   

3. Save and exit nano.

4. Restart.

And that's all.

Answer 2

Just upgraded to Ubuntu 15.10 and this doesn't work anymore.

Follow the steps in Marcelodata's answer (first method), but use this fix:

# IdeaPad Z470
evdev:atkbd:dmi:bvn*:bvr*:svnLENOVO*:pn*IdeaPad*Z470*:pvr*
 KEYBOARD_KEY_a0=!mute
 KEYBOARD_KEY_ae=!volumedown
 KEYBOARD_KEY_b0=!volumeup

Note the change from keyboard:dmi to evdev:atkbd:dmi
