Thanks for the response.
I do have an Nvidia 6800, and maybe I should have explicated the move from Edgy to Feisty a little better - but I didn't think a lot of folks had issues going the in-place upgrade route. Ironically I did too on my initial attempt, and consequently went for a full install since I do not use the Linux environment for any production activity on this system & had nothing on that partition to lose.
If I must add, I never had as much as an issue with Edgy overall, I had Synaptic, Adept & I made use of Automatix quite often to expand the tools available to me. For now I have not re-added Synaptic but I already have Automatix put on the Feisty installation.
Before finally settling on Kubuntu I tried out more than a handful of distros & I'm sure there's probably something better suited to *my personality* with all the plethora of distros out there.........LOL
With this install, I've noticed a couple of unexplained quirks, one for example is within the appearance-settings console. The KDE Theme Manager is stuck on Kubuntu 02 - a few other themes are there but there's no way of switching to any of them. I have adjusted to the less intuitive nature of doing things that remain the status quo in Linux but I must confess it does get me fuming sometimes all the trouble one has to go through to get simple things accomplished a lot of times.
Normally after such incidents I tend to take a vacation from the OS to maintain my sanity before returning to it usually after a few weeks.
