It has always been easy in Kubuntu to change the CPU frequency by just right
clicking the battery icon and setting the CPU policy but that is not the
problem at all. The problem is a program all of a sudden taking 100 % of the
CPU and not letting go. Dropping to "powersave" did not stop the problem
although it did get the temperature of the CPU down to 79C. To stop it
required a reboot, then the temp came back down to the normal after a minute
or so. However, for no apparent reason, about two hours later it all
happened again. Again, according to top, it is python taking 100 % of CPU.
and again the only way to stop it is to reboot. The logs do not tell me what
is going on. Or at least I find no mention of python. This is not normal
for this machine and only started a few days ago. Like I said, it's normal
CPU temp is about 46-49 and has been for several months.
