I don't have a concrete answer for you, but I have both installed and both seem to be working as they are supposed to and not interfering with one another.
Thank you for your reply.
I have 3 questions:
1)The ACPICPUThrottle v1.01 works well I think, but when I work without power supply (only with batteries) the laptop work slow, and sound works bad. And when I plug power supply again, I work slow until restart (with power supply, of course).
2)I use the autostart version, Can I use the GUI to config the application? Where is the GUI? I have the three files.
I need the two features: CPU change speed and precise battery metter, and for this I installed both.
