Ubuntu – X250 trackpad multi finger gestures not working after Sleep

I'm not able to answer all of your questions, but I can answer #3. If you're using a touchpad on your laptop, you can click on the Power button (upper right-hand corner), and choose "System Settings". Then, click on the Mouse and Touchpad option. In there, click the tab for touchpad, and uncheck the "Enable mouse clicks" option. You can also set the scrolling to Disabled, or Edge Scrolling.

As for the other two questions, you can always try updating to see if that fixes the issues. If you open Software Center, you can search for Synaptiks touchpad management, or touchpad. Install the appropriate application (synaptiks is for KDE, but it should work in Unity as well), and configure the touchpad.

Hope this helps you, and have a great weekend:) Patrick.

I'm having the same issue. I could manage this using a temporary workaround by removing the touchpad module from the kernel and adding it again. To remove:

sudo modprobe -r psmouse

To add again:

sudo modprobe psmouse

After that scrolling works for me.
