So, I've been running Ubuntu 12.04 since a couple of months before the official release. Everything seemed as right as it should without any official NVIDIA drivers. Recently I've been getting an error message upon booting every time, and it seems to be running quite warm, around 59-60 Celsius while running basic programs like Firefox or Libre Writer according to PSensor. Is this too hot? It seems like it would be considering what I'm running.
