I have Kali Linux installed on Latitude e5530. Everything seems to work well, except my touchpad. I can't use its edge for up/down scrolling. It's not a very big deal, but is annoying and is something I would like to fix.

I tried googleing, I tried search through Kali forums, but found nothing useful.

Here's some command outputs that I've tried:
-----------------------------------------------------------------------------------------------------------------------------------------
root@kali-to-go:~# xinput -list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=11 [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)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]
↳ Dell WMI hotkeys id=12 [slave keyboard (3)]
root@kali-to-go:~# synclient -l
Couldn't find synaptics properties. No synaptics driver loaded?
root@kali-to-go:~# egrep -i 'synap|alps|etps' /proc/bus/input/devices {this one shows no putput}
-----------------------------------------------------------------------------------------------------------------------------------------
Also, "System Settings" / "Mouse and Touchpad" shows only "Mouse" tab. There is no tab for touchpad.

Any clues what to do?

Best regards and TIA
