Post the output of (when the CPU is sky high loll):


The System Monitor is not showing the process that is using your CPU, but top will.

I see something similar. I guess it's something that could be turned off in the start-up menu. I haven't bothered finding out what because things return to normal pretty quickly.

Thanks! I didn't even know about the top command, it turns out it was whoopsie and kworker going crazy. Read around a little, and kworker will use a lot of cpu on some computers when the battery isn't fully charged or when running on battery power. As for whoopsie i just had to disable the crash reports to Ubuntu and it stopped.


All normal once more, thanks again for the help!
