Using default ksplash screen, I've experienced the similar problem on my machine (Celeron D 2.4GHz w/512MB). kubuntu dapper upgraded to KDE 3.5.4.
Changing default ksplash to MoodinKDE reliefed the bug. Any one who met same problem ? -- ksplash hangs on initializing system services sometimes if "Start with an empty session" is enabled https://launchpad.net/bugs/46682 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
