Can you be more specific than "messed up"? I'm actually looking at this very device as my next Linux laptop. Do you mean it performs badly? That the hardware is bad? That the drivers don't support something you want to do?
But the most annoying problem was definitely the damn trackpad. The main problem is that it's horribly jumpy and unpredictable. No matter how I tweaked the options for the device, it would hop erratically. Most annoyingly, the act of lifting my finger away from the trackpad would cause the cursor to move. So, for example, I would move the cursor over a 'close window' icon, lift my finger to do something else (e.g. press a button/whatever) and the cursor would no longer be over the icon. I'd then have to reposition the cursor. So frustrating that I just gave up on the trackpad for a while and started using the trackpoint (which, I tend to call "the nipple").
Eventually, due to all of the problems taken together, I just started using Windows 7 (which, to my surprise, I actually like) with Ubuntu running in VirtualBox. All problems seem to be gone. Trackpad is totally fine in the VM.
Yes.
> And is the laptop heating up more when you are running a vm ?
Not really but I honestly haven't hammered on the VM yet. I gave the VM 1024mb
> Are fans louder when running ubuntu in a VIM ?
Nope. I've heard stories about loud fans on the x220. My fan is dead silent. I actually have to put my ear close to the machine to know it's running.
That said, you should try to use the TrackPoint, since it's a much more efficient pointing device once you get used to it.
I just increased the sensitivity of the TrackPoint. When I use a MacBook (supposedly the pinnacle of trackpad technology), I feel like the cursor is moving in slow motion.
