I want to like Linux but ...

So just now I plugged a new keyboard into my Linux machine at work and booted. When I logged in, I got a pop up that said:

Now, I'm not a Linux noob, I've been using it for five or six years longer than I've been using Macs, but I don't deep dive into the various options and settings - once I get it working, I've learned to leave it alone so it'll keep working - and I'm damned if I can work out from that message whether pc101 refers to the X system settings or GNOME settings, and which of then actually refer to my keyboard (I did count ... it's a 105 key keyboard).

No big deal, but this is why I'm relieved to get home to my Mac.

(Other annoyances - apparently broken firewall and inability to set up screen spanning in a shorter time than 16 hours)
