Hi! Is possible to downgrade KDE from 4.2.1 to 4.2.0? I upgraded form 4.2.0 to 4.2.1 and 3d acceleration has disapeared and I don't have any desktop effect. Since I don't see significant improvements in 4.2.1 I prefer to go back to 4.2.0 and have my effects, which useless eyecandy appart, like those exploding stuff, are rather practical. Thank you
