comment ubuntu freeze when I plugged the power cable
I kept experiencing the problem until I did a kernel upgrade to 3.5.0-21. That fixed it for me and I have no AC adapter, battery or dim screen problems.

comment ubuntu freeze when I plugged the power cable
Had the same problem again. Empirically, I noticed that I had inserted an SD card and had a GNOME extension to show and unmount removable media on the top panel. I turned off the extension, the problem went away. Seems to me that it is a problem with GNOME 3 and extensions/indicators on the top panel, since your problem was with jupiter (which is an extension or indicator program) and mine with this "Removable drive menu" extension. It has something to do with the battery indicator when you plug/unplug, as if it doesn't get along with other indicators/menus. Have to say I'm new to linux.
