Hi everyone,
I really struggle on how to describe my problem in english. I recently bought a Thinkpad X240. It has a touchpad:
xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ xwayland-pointer:13 id=6 [slave pointer (2)]
⎜ ↳ xwayland-relative-pointer:13 id=7 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ xwayland-keyboard:13 id=8 [slave keyboard (3)]
Device: SynPS/2 Synaptics TouchPad
Kernel: /dev/input/event18
Group: 8
Seat: seat0, default
Size: 109x96mm
Capabilities: pointer gesture
Tap-to-click: disabled
Tap-and-drag: enabled
Tap drag lock: disabled
Left-handed: disabled
Nat.scrolling: disabled

So I configured everything using the gnome settings application. Touch to click as well as two-finger-scrolling work very well.
But: When I mov ethe mouse very slowly in a diagonal way it becomes visible that it is not moving smoothly. It really looks much more as if it would be moving in little angles. Like so: ┘ instead of /. If you think of it in a graphical way.
I hope this is understandable. At least a little. Since I have no real idea on how to describe this in english properly I have no idea on how to google for a solution or at least I did not find something on that matter.
Any idea on how to solve that issue? I think it really is a problem with the touchpad because if I use the trackpoint everything works.
Thank You

Just in case somebody has the same issues: The problem is the resolution of the touchpad.
These lines in the according xorg config file solved the problem:
Option "VertResolution" "1000"
Option "HorizResolution" "650"
