I recently had someone install ubuntu on my laptop and something just doesn't feel right about it. I am a newbie and don't really know what I'm looking for or how to look for it. after trying to make sure none of my hardware had been swapped out and trying to find my webcam, I discovered I was set up as a user only. I asked for the superuser pass and I was told the root password but even logging in as root doesn't allow me access to hwinfo. also when I try to run anything sudo related I get 'can't resolve host sudo'. can somebody please help me with this? is this normal?
I think your problems with "unable to resolve host blackbook" are not directly related to your problems with starting hwinfo. The latter, I suspect, is caused simply by the fact that hwinfo in not installed by default. At least I checked a few of my machines and none of them have hwinfo installed. I have to admit that I don't have access to a recent "vanilla" Ubuntu box - all of mine were upgraded from older Ubuntu versions. To install the program open a terminal and type the following:
(actually, the error message should've told you to do so). Enter your own password when it asks - not root's.
Then you'll be able to start it by typing
(provided that it needs to be started as root, as somebody stated in the comments. Otherwise just type hwinfo)
