I have just installed Ubuntu 14.04.2 LTS on my Lenovo-G50-30 laptop, replacing Windows 8. Systems settings --> Mouse & touchpad has no options beyond primary button, double-click and pointer-speed. How do I enable touchpad scrolling?

Go to your Ubuntu Software Center and install Pointing devices.

  • Done that. It has 'use wheel emulation' where you can set the button from 1, 2, 3 or 4. 1 is left click, 3 is right click, 2 and 4 don't seem to do anything. Right click and scroll will do for now, but I would prefer two-finger, or edge-of-touchpad scrolling. – Raffles Feb 21 '15 at 20:24

Follow the instructions here: http://iseborn.eu/2014/07/21/activating-wifi-in-ubuntu-on-lenovo-yoga-2/ to make a new module, but I don't want you to use the ideapad_laptop.c from that site, use https://www.dropbox.com/s/w6ltq7uy5sv9cww/ideapad_laptop.c?dl=0 instead

And if the make install command gives permission errors use sudo make install

Touchpad should return to normal after make install or sudo make install and with any luck your wifi should be unaffected and you can remove the blacklist file with sudo rm /etc/modprobe.d/ideapad.conf
