logfile from lxdm

in yocto 2.0 we used lxdm as display manager, now i tried a testbuild using yocto 2.1 and in this image lxdm is just displaying a black screen (i tired it with or without autologin configured, but this made no difference).

lxdm and X seem to be running, just not displaying anything

root@xxxxx~# systemctl status lxdm

forgot to mention when i just start xfce with startxfce4 manually xserver and xfce are working without problems, so the problem occurs only with lxdm

Well the log says "Message: spawn lxdm-session fail" which looks like lxdm is broken.

lxdm isn't part of oe-core so this isn't a suitable place to report the bug, you should contact the meta-oe maintainers unless you can clearly demonstrate that it's a bug in oe-core and not lxdm that needs updating for changes in oe-core.
