Comment 9 for bug 37529

Same problems as above. Upgraded from Kubuntu 5.10 to 6.06 (64 bit).
Generally runs and boots fine. During boot up kdm randomly dumps out to a console login (tested at about once in 4 - 5 reboots in succession).
Xlog files looked normal. Found 'kdm_greet' messages (as above) in syslog.
Didn't have a ~/.face.icon file, but added one anyway with System Settings panel, and all seems to be well.

Added bonus is that it fixed another bug too: Previously choosing 'K' -> 'Logout' -> 'End current session' dumped me into a console login (kdm failed). Now it appears to work.
