Bug#888493: xserver-xorg-input-libinput: Thinkpad T560 trackpoint completely unusable

Salvo Tomaselli-3
Source: xserver-xorg-input-libinput
Version: 0.26.0-1
Severity: important

Dear Maintainer,

Switching from stable to testing, libinput became the default.

Unfortunately the trackpoint is basically unusable. It is incredibly
sensitive, but this value seems to change at random, so applying a constant
pressure on the device results in the cursor jumping around at various speeds.

For now my solution was to remove the package and keep using the normal
xorg input method.

It seems that the library is completely untested on trackpoints.

Best

This fedora bug seems to be the same issue.

Things are starting to depend on the new version of this package,
which is still completely unusable to me, and there seems to be 0
activity on this issue.

Is debian planning to drop support for running on thinkpads?

No. You can still switch to xserver-xorg-input-evdev for it. FWIW, the
trackpoint works just fine here on my Thinkpad X230.

One thing you could do is downgrade to a previous version, 1.8.x I suppose,
which you can grab from snapshot.debian.org. Unfortunately there's not much more
that we can do, but you should feel free to send patches upstream (see comment
38 in that bug you linked).

This is what i was already doing, but:

 kwin-common : Dipende: libinput10 (>= 1.9.2) ma la versione 1.6.3-1
sta per essere installata

Can't use an old snapshot.

evdev works much better, but my muscle memory is used to "properly
functioning libinput" at this point, it would suck to switch, but the
latest libinput is completely useless for moving the cursor around.
