Assistance with the VNC Gnome

[RuRat]

I try to perform tasks in the VNC gnome screen but some tasks are not allowed because I am not the admin

I followed the Guide to the T but obviously missed something

when i try to open synaptic or run the software updater i get a message that i am not allowed to perform action,

obviously a permission related issue.

how can i login with sudo permissions?

"Build a media server" - Trusty Tahr 14.04.1 LTS

I think I am having the same issues as RuRat with trying to run Gnome over tight VNC. When I try to start Synaptic from Applications -> System Tool -> Administration -> Synaptic Package Manager this messages shows in my putty window :
==== AUTHENTICATING FOR com.ubuntu.pkexec.synaptic ===
Authentication is required to run the Synaptic Package Manager
Authenticating as: tom,,, (tom)
Password:

If I try to open a terminal window using Ctrl + Alt + T nothing happens. If I use Applications -> Accessories -> Terminal I get a window but no command prompt.

If I try running "sudo synaptic" from the putty window I get :
no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory
error: XDG_RUNTIME_DIR not set in the environment.

(synaptic:1609): Gtk-WARNING **: cannot open display:

if "gksudo synaptic" from putty window:

I'm having this same exact issue trying to use the Synaptics tools. Has anyone found a resolution for this?

By the way the "Leaking memory" (no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory) error in your log above, I solved this by using instructions from here...

http://ubuntuforums.org/showthread.php?t=2214042

apparently there is an issue in Samba.

If I find a resolution to the original VNC item, I'll post it. If anyone has it sooner, I'd appreciate the help!
