hi!
i fiddled with kde4 (opensuse-11) desktop effects, enabled a few desktop effects - i think i turned on with opengl...
and then all screen turned white... my all other users are logging properly but with the root login, kde4 is dead!

i tried to recover it but couldnot do that...
finally i did a simple thing - renamed the .kde4 directory in /root

mv .kde4 .kde4.orig

and desktop recovered- KDE came out of its hibernation!!
but i know thats not a decent way of clearing things...
can anyone suggest how to recover from such a situation, please

thankx!
