4 years ago Hi,
Try to upgrade your kernel to latest stable and rebuild iichid than. If you are lucky enough this will enable interrupt mode in the driver and this weird motion will go away. It will not help if your touchpad uses GPIO interrupts which are not supported by FreeBSD yet but it is worth trying.

4 years ago Thanks - unfortunately, with the 12-STABLE I tried (r358121), the touchpad is dead again (yes, I remembered to rebuild iichid:-). Maybe I should try CURRENT?

IIRC all relevant commits were MFC-ed before new year, so no need.
Could you place console output after sudo kldload iichid.ko here?

4 years ago Well, from dmesg, but it seems to be identical to what is printed on the console (also seems identical to what I got on 12.1-RELEASE except for the address after "allocated irq at"):

4 years ago Btw, it seems the STABLE kernel auto-loads ig4 and iicbus for me, while I previously had/needed
kld_list="/boot/modules/i915kms.ko vboxdrv ig4 iicbus iichid"
in rc.conf - I still have it, but I commented-out the whole line and rebooted in order to get the output in the previous comment - and noticed that ig4 and iicbus were already loaded despite of this.

4 years ago Sorry, I only now noticed that the touchpad was on /dev/input/event5 instead of /dev/input/event3 where it was before - updated the xorg.conf snippet accordingly, and the touchpad works again - and the "moving on its own" issue is gone! Thanks a lot again!

4 years ago Apropos that, I see that UDEV is enabled by default in the latest version of the xorg-server port (released 2 days ago:-) - I guess I should upgrade...
Hi, this driver has made my dead touchpad (ELAN0608 on Lenovo ideapad 320) come to life, thanks a lot for that! There is a weird issue though - if I move the cursor/pointer and let go of the touchpad without first stopping the motion, the cursor continues to move on its own at the same speed until it hits the closest edge of the screen (also continues along that edge until it reaches a corner). It can pretty easily be avoided by stopping the motion before letting go of the touchpad, but it does seem like it shouldn't happen...
I have no idea if this is something that can be addressed in this driver, but if there are any patches or the like that I can try out, I'll be happy to do so. I'm using the FreeBSD port version 0.0.1 on 12.1-RELEASE.
