Re: Troubles with X1 Carbon 2018 (X1C6) TouchPad and TrackPoint under Linux

2018-03-23, 0:46 AM

with X1Y3, does anyone have an issue with TrackPoint being "hyper-sensitive" under wayland - using ubuntu 18.04, gnome wayland? i have set the mouse speed to -1 but it is still to jidderish and not usable... since TrackPad is disabled using an external mouse.

 

i have seen couple of libinput bugs entries:

* https://bbs.archlinux.org/viewtopic.php?id=231494
* https://bugzilla.redhat.com/show_bug.cgi?id=1509017
* https://bugs.freedesktop.org/show_bug.cgi?id=103959

 

but so far i'm not able to solve it. any hints would be welcome.

An earlier post mentioned changing /etc/default/grub had no effect.  Probably you need to edit the efi boot entry.  For me in Fedora it is:

 

sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Thanks Stefan. This solved the unresponsive trackpad after sleep for me.

I actually had to create a file in /usr/lib/systemd/system-sleep (using fedora). Named it trackpad and did chmod 755 on it.

 

Here are the contents:

 

#!/bin/sh
if [ "${1}" == "post" ]; then
  echo -n none > /sys/devices/platform/i8042/serio1/drvctl
  sleep 1
  echo -n reconnect > /sys/devices/platform/i8042/serio1/drvctl
fi

I tried the fixes outlined above and the only thing that "worked" is disabling the trackpoint in the BIOS. Which is not so great since I've no lost the physical buttons. Though it is better than no trackpad. This was ubuntu 18.04 beta2.

Weirdly, with the live boot of fedora 28, closing the lid, waiting for the sleep pulse on the red 'i' light, then re-openeing made my trackpad work fine. I went ahead and installed to disk and this little trick is no longer working. How do I go about finding out what made it work in the first place?

Is the issue still there?

If so, please attach the dmesg.
