Hi guys,

I got a somewhat strange problem that i don't know how to handle. Tried searching these forums and googled a bit, but to no avail.

My problem is as topic says. I can log in using console and then startx, but using kdm or xdm only results in a restart of given service (xdm or kdm), with this in the logs :

Code:
Jun  5 14:46:56 localhost kdm: :0[6464]: pam_open_session() for andip failed: Cannot make/remove an entry for the specified session
Jun  5 14:46:56 localhost kdm: :0[6464]: Client start failed
Jun  5 14:46:56 localhost kdm: :0[6464]: pam_close_session() failed: Cannot make/remove an entry for the specified session

Now, this macihne worked perfectly for quite a while before this happened. It happened in correlation with some updates, though i'm not sure which ones. I ran etc-update, and i usually choose to manually merge the "important" ones, that i know i use non-defaults. i must've missed something during this update though.

I use :
Quote:

* sys-auth/pambase
Latest version available: 20081028
Latest version installed: 20081028
* sys-libs/pam
Latest version available: 1.0.4
Latest version installed: 1.0.4

* kde-base/kde
Latest version available: 3.5.9
Latest version installed: 3.5.9

* kde-base/kdebase-pam
Latest version available: 7
Latest version installed: 7


If any more info is needed let me know.

It's not a huge problem, but annoying that i can't figure it out.

I have exactly the same problem (but I use kde4). I must log in in a vt and then startx.
revdep-rebuild don't rebuild anything and the emerge you suggest don't do anythink useful. I have the useflag 'pam' enabled.

My /etc/conf.d/xdm:

Code:

# We always try and start X on a static VT. The various DMs normally default
# to using VT7. If you wish to use the xdm init script, then you should ensure
# that the VT checked is the same VT your DM wants to use. We do this check to
# ensure that you have't accidently configured something to run on the VT
# in your /etc/inittab file so that you don't get a dead keyboard.
CHECKVT=7

# What display manager do you use ?  [ xdm | gdm | kdm | kdm-3.5 | kdm-4.0 | gpe | entrance ]
# NOTE: If this is set in /etc/rc.conf, that setting will override this one.
# KDE-specific note: kdm-3.5 and kdm-4.0 are just examples. You will find all
# possible versions by looking at the directories in /usr/kde/.
DISPLAYMANAGER="kdm"

i am, and have been, using the pam useflag. i also use kdm in /etc/conf.d/xdm.

i've emerged kdm via the "kde" meta-package, so emerge -pv kdm output is a mess, but it'lljust show you i use the pam useflag so i guess it's no big deal.

seems kde is being updated now, so i'll check if the problem still persists after this update
edit: strike that, the update is not installed due to blocking, so i guess i'll have to wait for devs to fix that problem first.
(individual packages seem to have an update, but not the meta-package or something).

I solved:

Code:

sudo chmod +x /usr/libexec/dbus-daemon-launch-helper


Now kdm works.

i will, once my problem is solved. right now i cannot confirm if this fix works or not, as i'm currently without kde due to meta-package hell, and the fact that kdelibs-3.5.10 just won't install.
