Freenx server on fedora 15 the ability to log in as root or privilege escalation from a normal user?

Question

linux

It costs fedora 15, freenx server is up, I cling to Windows nx clientom as a regular user (not root), I run Aplications-> Accessories-> Disk utility, I try to format several disks, it says Permission Denied (not Authorized), when I sit at the machine locally, it asks at this moment my password and as I understand it elevates my sudo privileges, and through freenx does not want to ask how to fix it?
For a solution, I try to log in as root through nx, loads the graphics mode and issues A problem has occurred, please logout.
The question is whether it is possible to enable sudo itself to run in freenx, or to log in as root in it.

Answer 1

isn't it faster to open a console and write sudo mkfs.ext4 /dev/adN?

Answer 2

try kdesu/gksu

Answer 3

Do you log in locally and remotely with the same user or different ones?
