no permission to do anything and no root access

If you need admin power, prefix your command with:

sudo

eg:

sudo apt-get update

Use your login password as authentication. If you are running a graphical app then use gksudo. Eg:

gksudo gedit /etc/default/grub

You have that with sudo. The use of sudo is a good idea and it stops you loogin in to the GUI as root. If you do log in to the GUI as root then ALL Your applications (even web browsers) will run as root, any malicious software and scripts will also get this access and can do all manner of things to your OS. If you use the OS properly (as user) then the access is restricted greatly and you will have fewer issues. This is why idiot Windows users who log in as 'administrator' to check emails and play games get issues, all the viruses and so forth have completely unprecedented access.

If you think the use of sudo should not be used because you are the only user of the OS then you should use the sudo method as you clearly have litle knowledge of what logging in as root actually implies and does to the OS.

It's not supported and simply not needed. I have given the methods of getting 100% access to the files using sudo. This will keep the admin access low and your system safe. If you want a root terminal where you will not be asked for your password repeatedly (incidentally, sudo has a 10 minute grace period) then simply run:

sudo -i

and you can run:

exit to end it.

If the files you are accessing are owned by root, then you can mount it differently to give access to other users and so forth. Sounds like an issue with either what you are sharing or how you are mounting the share.

If you really need to become root then all you need to do give root a password. I will give you the command but strongly recommend you don't use it. There are very good reasons why Ubuntu has locked the root account by default.

if all you want to run the file manager as root then press ALT+F2 to open the run box and enter

---------------------------------
gksudo nautilus
--------------------------------

You are now a super user inside the file manager and can make the changes you want.

if you really want to be root however enter

-------------------------------------
sudo passwd root
-------------------------------------
then set a password

You can now log out and back in as root

and enter a password

You can change access using:

sudo chmod SOMETHING /path/to/folder

or

sudo chown /path/to/folder

You DON'T need to set the root password and it is not advised or supported.

I was able to resolve my own issues by dumping the gnome desktop stuff and going with KDE stuff.
better options to manage settings. thanks anyway

You clearly have little appreciation of security in your OSes.

I suggest reading these guides:
