You probably passed my son going in exactly the opposite direction! Too many Kubuntu driver problems. Started with Suse, left and now he's back. But he is convinced Suse has gone to the dark side now that they are working with Microsoft.
Really!? I have always had problems with Linux drivers (mostly sound, video and winmodem -- my fault on the latter) until now. Kubuntu 6.10 installed seamlessly (except it didn't recognise my 2nd-hand monitor, but then nothing else does either). I was okay, not delerious, with Suse (installation was a nightmare) -- but my Kubuntu installation could have been completed by a novice.
I was willing to put up with SuSe installation, and package system, until they went over. Ubuntu's package system is FAR better, and even includes the huge timewaster of years before, Lincity.
