Comment 68 for bug 1590590

My kernel got upgraded from standard repositories. I use Dell Latitude E5470. Now the touchpad and trackpoint are recognised:

mskrzypczak@dell-latitude:~$ xinput -list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS DualPoint Stick id=13 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS DualPoint TouchPad 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)]
    ↳ Power Button id=8 [slave keyboard (3)]
    ↳ Sleep Button id=9 [slave keyboard (3)]
    ↳ Integrated_Webcam_HD id=10 [slave keyboard (3)]
    ↳ DELL Wireless hotkeys id=14 [slave keyboard (3)]
    ↳ Dell WMI hotkeys id=15 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

Also, I can see the touchpad options in the System Settings tab.

However, I notice the following behaviours:
1) I cannot turn off the horizontal double-finger scrolling.
2) The horizontal double-finger scrolling is unproportionally fast.
3) It happens that without any activity (and no external mouse connected) my mouse pointer moves around the screen (!) (it happens even when I disable touchpad in system settings, so I believe it must come from the trackpoint).
4) I notice spontaneous clicks while moving the cursor using touchpad.

Do you think it is possible to add options to the Mouse & Touchpad tab to control 1), 2) and 3)?

What about 3) and 4)
