I noticed that the cpu on my linux machine (ubuntu 14.10) was running at 20 with me having done nothing (haven't opened an application) and on checking my graphics card, i see ubuntu at the same time has mesa installed (make me assume that gpu is also active). how can i reduce this load on both gpu and cpu
The 20 percent [20%] CPU usage you see on your computer has something to do with the programs currently running in the background. These are the programs that start automatically with your operating system. This issue also happens to me but not frequently. Sometimes a startup program has a scheduled task that needs to run silently.
And this is the time that you notice that there is something being processed by the CPU and yet you are not running any applications. This is normal actually. In Microsoft Windows, whenever I see this happening and I know I am not running any program, I only restart the computer and the system is back to normal.
Once the operating system has fully booted, the 20 percent CPU usage that happened earlier will not happen this time. It’s like interrupting the scheduled silent task and going back to normal. Actually, sometimes, I just ignore it since I’m not doing anything. There is no problem if you allow it to continue because it will eventually stop soon.
