lightdm init crashes

[noname2]

ive got 2 machines running 11.10
lightdm 1.0.6-0ubuntu1.2

someday lightdm didnt work anymore. and at login the desktop hang for 30 secs.
completly removing and reinstalling does not fix the problem cause /var/lib/lightdm got wrong permissons on reinstall.
thats the first thing to fix.

gdd works fine. ill test dan upload logs soon.

[ 4.691691] init: failsafe main process (825) killed by TERM signal
[ 4.692040] init: apport pre-start process (945) terminated with status 1
[ 4.706158] init: apport post-stop process (992) terminated with status 1
[ 4.707365] init: lightdm main process (952) killed by TERM signal

gdm is group 126
and lightdm 108
may i should mention that ive got an ssd so the boot is abnormal fast and there may are race conditions or something like that.

well setting permissons on /var/log/lightdm fixed it.

[ 4.733093] init: failsafe main process (869) killed by TERM signal
[ 4.734064] init: apport pre-start process (991) terminated with status 1
[ 4.742415] init: apport post-stop process (1031) terminated with status 1
[ 4.745009] init: gdm main process (1028) killed by TERM signal

is that ok?
gdm still installed.ill try with removed gdm

[noname2 (noname2-deactivatedaccount)]

removed gdm => total fail
gdm itself works.thats really annoying

attached dmesg lightdm and gdm logs

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

I can't login to the system using lightdm

i have to login through ssh from other PC and stop lightdm then start gdm to be able to login

i can't even login to the recovery console from lightdm

I don't think it's log file permission problem because the files last change date is today

Thank you
