Thinkpad T400 with non working two finger scroll here running Kubuntu 20.04, I just wanted to comment that none of the above solutions worked for me, but one that I found buried in a youtube video did get it to work! And I just can't leave it visible ONLY in a video, it's just not right.
What it boils down to is running these three xinput commands (I'm sure someone with more knowledge can say what this actually does and possibly the corresponding configuration file settings) xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Width" 8 xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 4 xinput --set-prop --type=int --format=8 "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Scrolling" 1 0 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1722478 Title: Two-finger scrolling and click-and-drag no longer works after resuming from suspend Status in Linux: Confirmed Status in kmod package in Ubuntu: Confirmed Status in linux package in Ubuntu: Invalid Bug description: I own a Thinkpad T440p onto which I have had Debian 9 running without hardware issues. I have recently installed Ubuntu 17.10 final beta to test it out, but two-finger scrolling does not work at the moment. It used to work out-of-the-box from the final beta iso, but a subsequent update broke it.
