I have had several problems with Ubuntu, and only 1 I have fixed.
The other problem on the other side is that there is absolutely no way to install Adobe Flash Player, everytime I find a solution, something has to block it.
Next, is that Ubuntu just shuts down automatically without any warning.
NOTE: I am using Windows 7 to talk to you.
I am already thinking about installing Linux Mint.
I have had less problems with Linux Mint than in Ubuntu.
My Ubuntu version is 11.10.
