I've noticed that there are sometimes (large) differences between the reported total CPU usage and a summation of the per-process CPU utilization given by apps like top and wmtop.

I have a very frustrating problem with my PC. I cannot install any recent version of Ubuntu Server (or even Desktop) since 9.04 even using the text-based installer. I boot from a USB stick created by Unetbootin (I also tried other methods such as startup disk creator with no difference).

Hi,
I have a USB wifi card (D-Link DWA-125) on a Windows 7 x64 computer. The problem is that the card appears on the "safely remove hardware" list, but I don't ever want to unplug it, so I would like to remove it from the list.
So far I have only found solutions that mess with the registry (and…
