I just wanted to throw a warning out there to everyone that the GPU Meter 1.1 (AddGadget.com) gadget can cause your system to hard lock moments after logging in.
Version 1.0 did not seem to do this but the update seems to trigger a quick failure in the communication with the video driver
leading to hard lock.
Anyway, I use a majority of the gadgets from Addgadget.com and like them all but this one is flawed severely. I have reported the bug to them so hopefully all will be right with the world soon.
