Re: Frequent freezing around login screens
W. Pepperdine,
Here are outputs of a few queries on log entries from one of my XFCE installations. How do they compare with your logs? Can you see any reports on your computer that could point to what is causing your issue?

During a freeze, the screen displays but is not updated and the USB ports appear inactive. There is no mouse or keyboard input, not even from SysRq. The only thing to do is a hard shutdown with the power button.
