How to enable multitouch for touchpad and touchscreen? I'm using Ubuntu 15.04 Vivid Vervet on a Lenovo ThinkPad X1 Carbon 3rd gen (Touch) 2015.
What does work:
- Fn+ buttons works out of the box – screen brightness, mute, volume adjustments, mic switch, Wi-Fi switch;
- TrackPoint with mouse buttons;
- Touchpad with 2 fingers multitouch (except pinch-to-zoom);
- Suspend;
- Keyboard backlight with 2 grades of intensity;
- WiFi, Bluetooth, WLAN;
- Touchscreen (multitouch doesn't work);
- Fingerprint reader.
What doesn't work:
- Touchpad multitouch with 3+ fingers;
- Touchscreen multitouch with 2+ fingers.
