After updating Feisty 1 hour ago i've accepted to overwrite gdm.conf-custom (During updates installation). After that i've rebooted and KDE was perfect.
I've added the XGL settings to gdm.conf-custom and KDE returned slow in drawing windows... ** Attachment added: "My gdm.conf-custom file" http://librarian.launchpad.net/6806323/gdm.conf-custom -- [Feisty] KDE apps in Ubuntu are slow in appearing and in using them https://launchpad.net/bugs/90422 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
