I am totally new to Ubuntu. I tried to install numerous times, but always removed it because of loud fan noise. Me and my Bro have the same Notebook, a HP Compaq 615, and what grabbed my attention that no apps where running the fan was still loud, so i opend up system monitor and saw that the gnome system monitor and saw that the gnome system monitor uses a lot of cpu, the value jumped up and down for a few seconds, but after it always used 50-60% of my CPU, i think thats a bit pretty large.
Than another research, i saw that the video card is not detected, we have an Ati Mobility Radeon HD 3200, but i did not install it because, every time i tried to install back in time and reboot i was never able to log back in to Ubuntu because i got just a purple background and a bog saying Error.
So my question is, can this high CPU problem caused by that my Video Card is not detected?
