Enable both: two finger scrolling and edge scrolling permanently
According with this answer, you can enable both two finger scrolling and edge scrolling using the following commands in terminal:
synclient VertEdgeScroll=1
synclient VertTwoFingerScroll=1
The problem is that these commands are not persistent after a system restart. To prevent this, let's put them to run at start up.
First, make a new small bash script called scrolling
with the following code inside:
#!/bin/bash
synclient VertEdgeScroll=1
synclient VertTwoFingerScroll=1
Save it in your ~/bin
directory, and don't forget to make it executable using the following command in terminal:
chmod +x ~/bin/scrolling

Then add the script scrolling
to run at startup:
