Bug Description

The keyboard is a thinkpad helix ultrabook pro which also has a mouse (nipple and touchpad), and extra battery, usb port. The port, battery, and mouse are detected. A usb keyboard works, as does a bluetooth keyboard (which is what I'm currently using). The problem exists in Ubuntu 14.04, 14.10, and 15.04.

Okay, I've installed the latest upsteam kernel (4.0.0-040000-generic) as instructed. It hasn't solved the issue. Also the link to the previous bug report was removed from my bug report, but this seems to contain useful information:

jonnieo, the issue you are reporting is an upstream one. Could you please report this problem to the appropriate mailing list (linux-input) by following the instructions verbatim at ?

Please provide a direct URL to your e-mail to the mailing list once you have made it so that it may be tracked via . It can take a day for the new e-mail to show up in the respective archive.

Thank you for your understanding.

Hi Chris,
Thanks for your guidance -- the linux kernel devs have now issued a patch to fix the keyboard and stylus. They are so excellent! See thread here:
https://<email address hidden>/msg16819.html
People can either wait for the new kernel, or patch it themselves via:

[install git if you don't have it], then

$ git clone git://
$ cd linux-stable
$ git checkout -b v4.0.1
$ git remote add jikos git://
$ git remote update jikos
$ git cherry-pick d92189ebbdcd0eb180317d8cd6d46c57ac9a3dc0

now save the attached patch in the linux-stable directory and

$ git am -3 hid-lenovo.patch
$ cp /boot/config-$(uname -r)* .config
$ make oldconfig
$ make -j8
$ sudo make -j4 modules_install && sudo make install

then reboot, enjoy, and thank the kernel team.


jonnieo, just to advise, as per the official archive is , not mail-archive.

Ubuntu 15.10 will run on kernel 4.1, will this fix be included? In other words should I save myself the hassel and wait for the new release or will that not fix anything and can I just as well patch and build the kernel myself?

Correction: will probably be kernel 4.2. The question still stands however.

Ok to post an update for those who don't know yet, the new ubuntu 15.10 fixes the keboard problem. The new kernel seems to include the fix, awesome!
