SE stands for security enhanced and seemingly there is a bug in Fedora's implementation of SE.
Currently the bug has been fixed and merged into the stable repo. You can nullify this bug simply by updating your Fedora distro. You can do so by having your laptop plugged in via ethernet and running the Fedora update software.
Seeing that you are a new user and you seem to be open to installing multiple distros let me give you a hint. When chosing a distro you must take the following into consideration. Now these are the most basic inital questions to ask of yourself.
1.Which has the most documentation.
2.Which has a substantial following so if I do have a problem that I can't solve on my own I can tap into that resource to solve my problem.
3.Which suits my needs for my intended use of my machine.
4.As a new linux user which distro seemingly is going to be easy for me to use.
5.What desktop environment suits me as a new user KDE or GNOME?
I think after doing a little research you will find that Ubuntu is most likely the answer in your case. Even though I use openSUSE I find that whenever I have a problem and Google the problem I find that Ubuntu forumn pops up first. This means to me that Ubuntu does have a huge following and typically posting a question related to your problem on their forumns will yield an answer quickly. I don't use Ubuntu myself because I have found that in my situation openSUSE operates faster when running mythtv which I suspect was caused by mysql. I also like how software updates are handled in openSUSE. ie one click installs of updated software via the openSUSE web site. Anyways, I would definitely try Ubuntu seeing that you have tried SLED 10 openSUSE and Fedora already without luck.
Oh, and when someone says list the output of a certain term they mean typing a command in a console. Simialar to going to START > RUN > CMD in windows.You'll find that in linux you will have to do this from time to time but once you get used to the commands then you find it is a powerful tool. Just remember to be patient. And also remember that all linux distros are not the same so when posting try not to bounce back and forth between distros.
