Ubuntu on Lenovo laptop/tablet X-220t hacks

view story

http://www.linuxquestions.org – <p>Hello fellow Linuxians, Back in November I installed Ubuntu side-by-side with Windows 7 on my Lenovo X-220t. I has uploaded Grub and Ubuntu seamlessly. However, I cannot make a few cool aspects of my Laptop to work, as examples: 1. Scrolling with finger on the screen (the screen does respond to tapping/clicking, however), 2. The fingerprint reader does not work 3. The screen rotate button while on tablet form, does not work. I would greatly appreciate if you fellow Newbies or pros out there could help. Be well</p> (HowTos)
