Solved Touchpad on Thinkpad X1 not working

B

balanga

The trackpoint on my ThinkPad X1 is driving me nuts because it is difficult to use and am not sure if there is anything I can do to improve it, however, when using Windows I often use the Touchpad so I now it is enabled and working, but it doesn't work on FreeBSD.

Do I need to install a driver to make it work?
 
look at dmesg output and find out. Looking at this dmesg: https://dmesgd.nycbug.org/index.cgi?do=view&id=8668
it looks like it is on sdio / i2c:
Code: 
iichid0: <ELAN06D4:00 04F3:32B5 I2C HID device> at addr 0x15 on iicbus0
iichid0: Using sampling mode
hidbus0: <HID bus> on iichid0
hms0: <ELAN06D4:00 04F3:32B5 Mouse> on hidbus0
hms0: 2 buttons and [XY] coordinates ID=1
hmt0: <ELAN06D4:00 04F3:32B5 TouchPad> on hidbus0
hconf0: <ELAN06D4:00 04F3:32B5 Configuration> on hidbus0
hmt0: Multitouch touchpad with 0 external buttons, click-pad
hmt0: 5 contacts with [C] properties. Report range [0:0] - [3689:1673]
 
I wasn't sure of which model or how to find out so I asked Chatgpt:-

discover which thinkpad x1 carbon you are using from within freebsd

answer:-

dmidecode -t system

Look at the first four characters of the Product Name:
Example CodeX1 Carbon Generation
20A7 / 20A8Gen 2
20BS / 20BTGen 3
20FB / 20FCGen 4
20HR / 20HQGen 5
20KH / 20KGGen 6
20QD / 20QEGen 7
20U9 / 20UAGen 8
20XW / 20XXGen 9
21CB / 21CCGen 10
21HM / 21HNGen 11

I must say I'm quite impressed, although I note it doesn't list Gen 1 which I think is what I have.
 
I have a 34431C4 which has an Official product name: Lenovo ThinkPad X1 Carbon (1st Generation)

FreeBSD X1 14.3-RELEASE-p5 FreeBSD 14.3-RELEASE-p5 GENERIC amd64

(X1 is the Hostname)

root@X1:~ $ dmesg | grep -i -b1 -a1 touchpad

I don't know why Touchpad appears twice.
 
I put the following into Chatgpt:

freebsd thinkpad 3443 trackpad not working

and from the answers, I got it working by enabling synaptics support for the trackpad. I hadn't enabled it previously.

I also found some setting to make the trackpoint perform better.
 
Can you do two-finger scroll on this touchpad? I have an old Dell laptop and while touchpad works in base mode I could not get more complicated gestures. I tried both synaptics and libinput with XFCE

Actually, I didn't know about two-finger scroll and wasn't sure how to do it, but with a little practice it does work. That is, in LXDE.
