Recently I purchased a Lenovo S340 for my daughter and installed LM 19.3 on one drive and MX 18.3 on the other drive. I have not been able to adjust the touchpad cursor movement to my liking. It seems to be the touchpad surface size relationship to the screen size. In other words if I place the cursor in the top right of the screen and my finger on the top right of the touchpad, I would expect as I moved my finger kitty corner to the lower left of the touchpad the cursor would follow to the lower left, but it only goes about 2/3 of the way on the screen, which necessitates another finger movement. Annoying to say the least. I have an S310 Lenovo that the touchpad works perfectly, and a 1" finger movement will span the whole screen. I also have a Thinkpad E15 with Qubes installed which has problems similar to the S340.

I have looked at xinput list-props and I can't decipher which attribute might effect this, unless it is the coordinate transformation matrix. It seems this would be a simple solution, but I have not stumbled across the answer yet. Any advice would be appreciated.--Thanks!

a couple of my thinkpads use the synpatics input driver. please feel free to ignore this if your lenovo does not. if so, synclient will show (at least most of) the same values as xinput list-props and this page (as well as man synaptics) may offer a more a more extensive description of what the values represent.

Thanks for the reply! I don't have the S340 to work on now so I can't check it myself. My Thinkpad E15 with Qubes though does not have synclient. Still looking for a solution.

when you do have a chance to look at the s340, my virtual machine version of lm 19.3 has a couple of settings under mouse and touchpad for acceleration and sensitivity. they don't seem to do much for me regarding the changes you want, but my touchpad performance in most vm's isn't very responsive. i would imagine mx has similar settings options.

i also looked at what driver is installed in mint 19.3 and it appears to be libinput. i originally switched to synaptics on my also-ubuntu-based distro (bodhi) because it increased the functionality of my touchpad. mine are clearly listed by xinput list as synaptics touchpads: SynPS/2 Synaptics TouchPad. if you wanted to try the synaptics driver it is xserver-xorg-input-synaptics (there is an hwe version in case the s340 has relatively new hardware) for mint and ubuntu. it is likely named the same thing or something quite similar for mx.

regarding the e15 with qubes, i don't use my fedora 31 install enough to know how to get it to tell me what input driver the touchpad is using and i don't see that listed when checking xinput list-props. i do see that libinput is listed among the base install packages by distrowatch whereas synaptics is not. dnf-dragora lists xorg-x11-drv-synaptics-legacy (or -devel) in case xinput shows your touchpad to be made by synaptics and you wanted to try a different driver for it.
