Wow, I've not seen any laptop whatsoever in the last 10-20 years that lacked this crucial feature. This is my first Lenova product and I can't help but wonder what other functionality they don't understand, do they even use their own products? How is a scrolling feature optional to them? What other corners did they cut that I'll only discover later? This thing is going right back to the store.
(bonus facepalms when they mark their threads on here "solved!" when the solution is "no, we didn't bother adding this very basic functionality that every other laptop on the planet has")

Just Google "2 finger scrolling Lenovo IdeaPad 100" and you will find both a registry hack to enable it or installing drivers from a different manufacturer for your track pad that have scrolling enabled... I use an Asus driver on my Flex 3 and 2 finger scrolling is working beautifully...

Plato1123 I don't have your laptop so it's not possible for me to walk you step by step. I must tell you that I can't remember ever seeing a trackpad not using PS/2 mouse port before so... If I was you I would create a bootable Ubuntu Live flash drive and boot with it and see if multi finger gestures are supported... If they are and they should then its a driver issue.

Just to confirm in device manager under "Mice and other pointing devices" the only listing is HID-compliant mouse. There's no listing for a ps2 device, even if I "show hidden devices". Also no weird bios settings to turn on ps2 mouse emulation or anything weird like that. Also, it appears the 100s-15iby has drivers for both HID compliant mouse and ps2 compatible mouse port but again just to confirm after triple checking the 100s-11iby that I have does not appear to use the ps2 bus, only HID (usb).

my 100s-11iby 80r2 lists its mouse as being a HID(I2C) device I got synaptics driver for I2C touchpads to install but no luck on getting scrolling to work. I'm going to try a lubuntu live USB and see if it has scrolling in the next few days if you found a fix let me (and others) know!
