lunm0us / linux-tp1gen3 Goto Github PK

I'm on an X1 gen1 with kernel 5.4 (ubuntu 20.04) and also affected by the non-working Trackpoint.

I have a question an request:

*) Reattaching the keyboard solved the issue and a simple "libinput list-devices" lists the trackpoint and is working well.
Is there a way to trigger this in SW ? Let's a say by a script after login ?
https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1878882

*) As a novice end-user, it would be very much welcomed if somebody could give me a bit more detailed info, how to build the dkms hid-multitouch kernel module ?

Thanks so much for providing this repo! It just saved my day and my X1 Tablet is now up and running.

I use Ubuntu and it took me a bit to 'translate' your instructions. Therefore I wrote them down. Please feel free to add them to your Readme.md

Best,
Sebastian

Ubuntu installation (DKMS)

1. download and extract linux-tp1gen3-master

cd linux-tp1gen3-master

2. edit ./hid/src/dkms.conf
   Replace the placeholders @_PKGBASE@ and @Version@ with the actual values being hid-lenovo-tp1gen3 and the current version (e.g. 0.2.0). The version can be determined from the PKBUILD file.

3. install the DKMS package

sudo apt-get install build-essential dkms 

4. copy files

sudo mkdir -p /usr/src/hid-lenovo-tp1gen3-<version>
sudo cp -a ./hid/src/* /usr/src/hid-lenovo-tp1gen3-<version> 

5. build and install

sudo dkms add -m hid-lenovo-tp1gen3 -v <version>
sudo dkms build -m hid-lenovo-tp1gen3 -v <version>
sudo dkms install -m hid-lenovo-tp1gen3 -v <version>

Check if the module was successfully added to dkms

~$ dkms status
hid-lenovo-tp1gen3, 0.2.0, 5.6.14, x86_64: installed

6. blacklist the old module
   Add blacklist hid-multitouch to the file /etc/modprobe.d/blacklist.conf
   Then reboot.

Hi,

first of all thank you for making my function keys work they it should! :)
Unfortunately in recent kernel versions a commit broke the functionality of the trackpoint. The bug is filed here and a workaround that requires the compilation of the kernel is discussed here.
This stuff is way above my level of knowledge so i am asking for help here. Specifically i am wondering if it is possible to modify the patches here to include the workaround without the need of recompiling the whole kernel after an update or ideally to provide the missing mappings and work on an upstream fix.

Please help looked at blacklisted devices but couldn't fix problem is there a special driver required?
