I've been using ubuntu since 7.04 and I have never had any issues with it hardware-wise, until I got my new laptop. I recently purchased an ASUS G46V after my house was broken into and refused to get to know windows 8; after a few failed attempts to install ubuntu 13.04 (I would install graphics card drivers and it would essentially break everything to the point where it wouldn't even boot) I fainlyl got 12.04 working. But since then a few issues are nagging at me that I'd like resolved.
Firstly, and probably the most annoying is the mouse. It has a touchpad mouse and it registers it as a generic ps/2 mouse. Though the touchpad works, the nice two-finger/edge scrolling features don't work, which really I've gotten used to just using my arrow keys, but I'd still like it fixed (I have the capability, might as well take advantage of it). I've already followed along with document section with this and there's no luck. I did see there was this whole manual way to remove and reinstall it, but it looked scary and after having to reinstall the whole OS several times I didn't want to break it all again. I also posted a question here but without much luck.
Secondly, my grpahics card. This is what caused all my hurt in the beginning, because every time I installed the restricted drivers for it, it would break everything to the point of it either a) not booting or b) the window manager being gone. It's an NVIDIA GeForce GTX, which is odd because I've owned several computers over the years, almost all with nvidia graphics cards and never any issues with them. I'm not much of a gamer, but I did buy a gaming laptop and it would be nice to put it to use and test its limits. I've followed a few guides with no luck, and I'm almost afraid to touch it again and break everything.
tl;dr My touchpad doesn't work, my nvidia GeForce GTX graphics card doesn't work.
Thanks so much!
