then

i install plasma5-session

then
i restart pc
then
i get kdm template according to open a session
then
i open a session
then
i see the new wallpaper
then
i get an error in a window : could not start ksmserver
then
i click on "okay"
then
i get again kdm template

no problem with icewm

with yast software manager i see that sddm is not installed and in yast "ect/sysconfig" manager i see that kdm is the current session manager and sddm is not in the choice
is this the pb or what else ?
