There is a change needed if you would like to use the Jupiter applet. If you are a desktop user and dont care about power management, battery life,, and changing screen resolutions, etc. Then you can move on as Jupiter will keep things running at maximum performance.
If you are interested in controlling those things, then two things are needed to be done post install.
The next couple of posts will give you the basics.
1. Add your user name to the Jupiter user group. User and group management is located under "Preferences" then "Users and Groups".
Step 2 - Reboot your computer (please)
And then you will be able to go to the Jupiter app in the panel and select many different options. This includes CPU, devices that are detected (like wifi, touchpad, bluetooth, etc) and screen size, external monitors, etc.
Why, for some reason, my PC won't show "Performance Modes" and "Device Control" in Jupiter even after reinstalling Jupoiter several times? Any answers?
Hi Dave, can you post your HW details on the machine your running on. I am digging into Jupiter deeper as it relatively new to me, but fairly well documented and put together.
The performance modes are determined by evaluating CPUFreq - so the processor has to support that.
Jupiter detects the availability of device control by evaluating the kernel for specific capabilities that have been detected and enabled. For example touchpad on a laptop, I tested on another that had bluetooth and it saw it and added it to the menu, etc.
So its fairly dependent on the HW detected. Another thing to look at is powertop from the command line and see if it lists multiple CPU modes for your computer to see if powertop thinks you can do that also.
