LXDE, LXDM problems after upgrade

If lxde-logout is hard-coded to use consolekit then it has to either be fixed upstream or patched in someway. With the current systemd + polkit, you can simply use these commands:

In my case, i found two things

In my case, if I killed polkitd and started again with:
/usr/lib/polkit-1/polkitd said me that was a permission problem on rules.d folder

When I fixed sill didn't work, on the next login
I put on autostart an script to kill autostarted polkit and open it again. Then works perfectly

sudo kill `ps aux | grep -i polkitd | grep -v grep | awk ' { print $2 } '`; sudo /usr/lib/polkit-1/polkitd --no-debug &

Teorically there's a lxpolkit daemon to do it, but it's still on AUR and finish with a Segfault on open. So it doesn't work...

Hope it helps

I just added @lxpanel to '~/.config/lxsession/LXDE/autostart'. Yeah I had to reconfigure everything, but most of the previous configuration was in tact and it only required a few tweaks, which yielded a fresh feel due to some different asthetic choices.

The logout problem I tried to solve by adding "systemctl reboot" and "systemctl poweroff" to the Openbox menu, but I only get child process errors when I try to use them. Can someone tell me the right way do this?

*Edit- I guess it's wrong to say I reconfigured everything, because I go on to explain that I don't.

There are already bug reports about this and a few very recent threads, why post here?

Hi, I'm wondering if anybody has run into this problem: lxde-logout (and lxsession-logout, because that's what it runs) takes 5 minutes to load, and slows down any X11 activity (e.g. focusing windows). It started happening right after I ran pacman -Syu on 2013-08-16. I tried following the fix for bug 36389 listed above involving enabling those lines in /etc/pam.d/lxdm, and that did not solve the problem.

I copied the source code from lxsession-logout.c into a new test file, debugged that with gdb, and found that the it is hung on the following statement (in lxsession-logout.c in get_background_pixbuf()):

GdkPixbuf * pixbuf = gdk_pixbuf_get_from_drawable(
NULL, /* Allocate a new pixbuf */
gdk_get_default_root_window(), /* The drawable */
NULL, /* Its colormap */
0, 0, 0, 0, /* Coordinates */
gdk_screen_get_width(screen), /* Width */
gdk_screen_get_height(screen)); /* Height */

Here is the backtrace:

The new test program does not depend on lxsession, and I ran it without any window manager or display manager running (using startx) and it hangs on the exact same statement, always with __poll_nocancel() at the top.

Also I ran lxsession-logout under strace -Ct and when it was hung it kept doing this over and over:

12:33:45 writev(3, [{"<\5\2\0\5\0\300\0017\1\5\0\6\0\300\1P\1\0\0\0\200\0\0\1\0\0\0>s\7\0"..., 60}, {NULL, 0}, {"", 0}], 3) = 60
12:33:45 poll([{fd=3, events=POLLIN}], 1, 4294967295) = 1 ([{fd=3, revents=POLLIN}])
12:33:46 recvfrom(3, "\16\0\200\0\4\0\300\1\0\0>\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 4096, 0, NULL, NULL) = 64
12:33:46 recvfrom(3, 0x15118f4, 4096, 0, 0, 0) = -1 EAGAIN (Resource temporarily unavailable)

That line of code is responsible for getting the image of the root window in order to re-display it darker before the logout options window appears. I thought then maybe this same behaviour would occur with "import -window root screenshot.jpg", but no, that functions without delay.

This is on my work computer. I upgraded on the same day my netbook, and after it did not have this problem. So I thought this might be related to merged config files, but there are not many new ones:

[carlos@nbcarlos ~]$ find / -name *.pacnew 2> /dev/null
/boot/grub/grub.cfg.pacnew
/etc/pacman.d/mirrorlist.pacnew
/etc/ppp/ip-down.d/00-dns.sh.pacnew
/etc/ppp/ip-up.d/00-dns.sh.pacnew

I am not using "testing".

Thanks for any help you can provide, and sorry in advance for missing anything or bothering anyone

Oh, and my lxsession version is 0.4.6.1. Sorry.
