But, having done that, I did not realize that you also needed to edit the sudoers file to add this new usernum, so once I can closed that root account, I was DOA.

I'm finding that pclos, despite is usability being a huge plus ON THIS MACHINE, doesn't talk to other linuxes all that well. And while I do run 10.04 on that box and a lappy I often use with it, generally speaking ubuntu is so damnedably difficult to configure, and is missing tons of usability features that Just Work(TM) on pclos. For instance, if I want to access one of the other 9 workspaces on this machine, sure, I can find the pager and double click it, or I can leave the mouse pointing at an unused point on this screen & just roll the wheel, one screen up or down in the 10 screen count per click of the wheel detent. On buntu, I have to first find the mouse as its up on a shelf due to space limitations at the operators console, then find the pager, click once on it to change the focus and click again on the screen I want to go to, and apparently the limit is 4 screens, which I find somewhat constricting even on a box with far less resources at its disposal than this one. Another thing this usernum difference may be responsible for, I can remember when I could "ssh -Y shop" and run emc, with motor power off obviously, from this box to preview what the code I had just written might look like in the backtrace. I think the last time I made that work I was running fedora 10 although its possible I made it work for mandriva 2008. It has never worked for pclos because the x server sees a request from an unknown user and bounces it. The ssh session works great for running text based things like vim though. IMO linux is growing up, and its time all distro's started using 1000 as the first usernum, leaving more privileged stuff below 1000. Like that is going to happen on my remaining watch...
