CID: 201209-11840 Dell XPS 13

Both of the edge scrolling feature (horizontal and vertical) does not
work on this system.

ubuntu@201209-11840:~$ xinput list

There is no E7 value in dmesg, and the only EC value is:
ubuntu@201209-11840:~$ cat /var/log/dmesg| grep EC
[    0.156762] ACPI: EC: Look up EC in DSDT
[    0.181523] ACPI: EC: GPE = 0x17, I/O: command/status = 0x66, data = 0x62
