If I type /usr/bin/update-manager in the terminal the graphical software updater is launched - from there, I get the same response as #1. I.e. the sudo window asking me to enter the sudo password does not launch and the gui crashes. If I enter sudo gparted in the terminal I get asked for my password and the gui opens - the gui will not open if I try and launch it from the main menu.
Any gui application that needs to fully launch by also asking for the sudo password (e.g. gparted, synaptic) crashes because the gui window asking for the sudo password never opens - the whole thing crashes. If I open the same gui applications from the terminal preceded by sudo .... the gui opens.
Code:
liz@lizubuntu:~$ sudo gparted
