[opensuse] Xephyr on OpenSuse 12.1 not working as expected.

Moin, I started with OpenSuse 12.1 and would like to "Xephyr" running. Its needed since we have to connect to remote desktops ( mostly CDE - AIX,Sun a.s.o ) Xephyr is working fine on OpenSuse 11.1 and OpenSuse 11.4 but on 12.1 i get only a black screen Error message: : Xephyr unable to use SHM XIMage And later : XDM: too many retransmissions, declaring session dead. Note: Display Manager is: xdm Any hint where to start debugging.
