How to correct mapping of Touchpad and 2nd Mouse device on Xfce?

My Synaptics touchpad is device number 7 and the left clik works on the xfce desktop but not on windows or the menu bar. Same goes for the external usb mouse, which is number 5. Device number 6 are two other mouse buttons present on the laptop (HP Elitebook 2540p). After boot everything works fine until I hit one of these laptop buttons then the mentioned behaviour above happens. I now want to disable the devices one by one to check which is triggering the error. I also tried evtest and every button works fine (left, right). So there is some mapping chaos in X happening.

Touchpad pointer keeps shaking when AC power is plugged in

I own a Fujitsu Lifebook A555 (i3,8gb ram etc), when i’m using ubuntu or any linux distro(i’ve tried all versions) for that matter my cursor keeps shaking even more when i’m touching it, i can’t say for certain if the problem is a hardware issue or not because this does not happen on and windows version (do note that my charger is not the original charger that my laptop came with), an external mouse works just fine and this problem never occurs in windows. Any help would be appreciated.

xinput property ‘Synaptics Noise Cancellation’ doesn’t exist – Thinkpad x220 – jittery touchpad – ubuntu18.04.3

I just installed ubuntu on my thinkpad-x220 and my touchpad is extremely jittery / jumpy. If I don’t touch it my mouse stays still which is fine, but once I start moving my finger on the touchpad the mouse shakes and moves which is so annoying.

Apparently this is a well known issue, but I’m not having any luck using the recomended solution of xinput:

When I run xinput I see this:

root@martin-ThinkPad-X220:~# xinput ⎡ Virtual core pointer                      id=2    [master pointer  (3)] ⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)] ⎜   ↳ SynPS/2 Synaptics TouchPad                id=11   [slave  pointer  (2)] ⎜   ↳ TPPS/2 IBM TrackPoint                     id=12   [slave  pointer  (2)] ⎣ Virtual core keyboard                     id=3    [master keyboard (2)]     ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]     ↳ Power Button                              id=6    [slave  keyboard (3)]     ↳ Video Bus                                 id=7    [slave  keyboard (3)]     ↳ Sleep Button                              id=8    [slave  keyboard (3)]     ↳ Integrated Camera: Integrated C           id=9    [slave  keyboard (3)]     ↳ AT Translated Set 2 keyboard              id=10   [slave  keyboard (3)]     ↳ ThinkPad Extra Buttons                    id=13   [slave  keyboard (3)] 

I run this command:

xinput --set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Noise Cancellation" 20 20 

but get an error message saying:

root@martin-ThinkPad-X220:~# xinput --set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Noise Cancellation" 20 20  property 'Synaptics Noise Cancellation' doesn't exist, you need to specify its type and format 

Touchpad randomly disabled upon reboot on lenovo x1c7

Just switched from apple to lenovo (carbon 7th gen), installed Ubuntu (19.04, with 5.0.0-25-generic). However, the touchpad randomly is disabled upon reboot (it is activated in the system settings). After rebooting the touchpanel sometimes starts to work, sometimes doesn’t. This happens only with the ubuntu partition, not with Windows. Can somebody help?
