The Mandriva situation is still preferable - under Kubuntu I can't pick the mode I want because it's not detected. Under Mandriva I *could* pick an invalid one, but at least I *can* pick the one I want. I'd rather have it not work due to my own ignorance/stupidity than due to flaws in auto-detection mechanisms that I can't influence. (Note however that I still choose to use Kubuntu despite this obvious raging flaw ;) )

I never made a change under Intrepid, it just worked. Hence no backups.
