I just dual-booted my PC with Ubuntu 12.04 alongside Windows 7. I like everything about Ubuntu except two things.
First, whenever I click the right mouse button in Firefox, it immediately hangs. I have to kill the process then. It becomes very annoying when I have several tabs open and I forget not to use the right mouse button. I had previously booted Ubuntu with UNetbootin, the same problem was there even then.
Secondly, when I had not installed AMD drivers on Windows 7, the laptop was just eating through the battery. Only after installing the drivers, did it come to cool down and started giving the 6 hours backup it was supposed to. Now, the problem is that in Ubuntu, the laptop is just throwing up the heat as if I am playing some heavy game. It goes without saying that the battery backup is poor - barely 2 hours.
Is there any solution for this?
And make that questions three - is there any beginners guide to Ubuntu? I feel seriously confused when trying to install a software. In fact I have no idea how to do it. I know there is Software Center but I have no idea how to operate it. The last time I used a Linux OS was Mint 8 few years back. At that time too, I felt seriously confused with all the commands you have to know about, in order to have any sense of control.
MY system is HP Pavilion G6-2005AX, if that helps.
