[SOLVED] delayed logout xfce4. lxpolkit segf. dbus probl

[salmonix]

Hi there,
I have the symptoms described at http://forums.gentoo.org/viewtopic-t-88 ... art-0.html unresolved post though *kits configured matching http://forums.gentoo.org/viewtopic-t-85 ... art-0.html - at my best...

In short: at logout I have the logout window delayed and responsiveness suffers penalty. I can only log out, but can not reboot or halt. Trying the latters I am prompted to enter a password but that is always rejected. I can not suspend or hybernate.

note: I tried emerging xfce4-session USE='-consolekit' at least 'solved' the stall at logout but not the logout-reboot button problem. now consolekit is back. .
Checking out messages I caught

Dec 13 10:16:37 [kernel] [ 1701.463891] lxpolkit[3288]: segfault at 7f7f962c83d0 ip 00007f7f951fb10d sp 00007fffddaa35a0 error 4 in libc-2.13.so[7f7f95185000+181000]

Replacing lxpolkit with polkit-gnome the segfault message is gone. Now a different comes when trying to log out.

I also have problem with automounting pendrive etc., perhaps related to this problem. upower -d is complaining:

Dec 13 10:45:37 [dbus] [system] Activating service name='org.freedesktop.UPower' (using servicehelper)
Dec 13 10:45:37 [dbus] [system] Activated service 'org.freedesktop.UPower' failed: Failed to execute program /usr/libexec/dbus-daemon-launch-helper: Success

and at inserting a pendrive kernel recognizes it but

Dec 13 10:49:46 [dbus] [system] Activating service name='org.freedesktop.UDisks' (using servicehelper)
Dec 13 10:49:46 [dbus] [system] Activated service 'org.freedesktop.UDisks' failed: Failed to execute program /usr/libexec/dbus-daemon-launch-helper: Success

Here my faint knowledge is exhausted - I do not have a really clear picture about the pam-*kit-dbus system to navigate further. More, for me this combo is a kind of mess with different syntaxes and all. So, till the shiny day it is cleared up I lean on others advise.

Thanx!

News.
I followed http://forums.gentoo.org/viewtopic-t-905296.html Hypnos advise and included polkit in USE flag list and also
-policykit.

However, the main problem - delayed logout, no reboot-halt function - has remained.

Ok then.
The solution was simply to change the permission of /usr/libexec/dbus-daemon-launch-helper too+x.

All runs fine - pendrive automount, suspend, no delay...

Thank you, salmonix. This fixed my problems too.

Never do that, unless you want everyone on your system to be allowed to gain root. As in, that is same as intentionally inserting a vulnerability to your own machine.

The solution is to recompile pkgs like dev-libs/dbus-glib after dev-libs/glib upgrade (as noted by elog in the end of glib emerge)
Propably 'emerge -e sys-apps/dbus dev-libs/dbus-glib' will do the trick if nothing else does

For anyone coming here from search:
A proper and easier way of fixing this would be to chown this helper to be owned by root:messagebus
