It seems like gnome-session (among some others) are flooding /var/log/messages and/or ~/.xsession_errors with debug printouts. I've linked to the same issue in Mandrivas bug database, even though the issue was fixed 2,5 years ago in their case. root@skare$ tail -n 512 ~/.xsession-errors /etc/gdm/Xsession: Beginning session setup... ** (gnome-session:6010): DEBUG: GsmDBusClient: obj_path=/org/freedesktop/DBus interface=org.freedesktop.DBus method=NameOwnerChanged ** (gnome-session:6010): DEBUG: GsmDBusClient: obj_path=/org/freedesktop/DBus interface=org.freedesktop.DBus method=NameOwnerChanged ** (gnome-session:6010): DEBUG: GsmXsmpServer: accept_ice_connection() ** (gnome-session:6010): DEBUG: GsmXsmpServer: auth_ice_connection() ** (gnome-session:6010): DEBUG: GsmXSMPClient: Setting up new connection ** (gnome-session:6010): DEBUG: GsmXSMPClient: New client '0x12f7140 []' ** (gnome-session:6010): DEBUG: GsmStore: Adding object id /org/gnome/SessionManager/Client2 to store ** (gnome-session:6010): DEBUG: GsmManager: Client added: /org/gnome/SessionManager/Client2 ** (gnome-session:6010): DEBUG: GsmXSMPClient: Initializing client 0x12f7140 [] ** (gnome-session:6010): DEBUG: GsmXSMPClient: Client '0x12f7140 []' received RegisterClient(10e7215f19c54e6581129248405239561900000060100018) ** (gnome-session:6010): DEBUG: GsmManager: Adding new client 10e7215f19c54e6581129248405239561900000060100018 to session ** (gnome-session:6010): DEBUG: GsmManager: ending phase WINDOW_MANAGER ... ... etc peter@skare$ eix gnome-session [I] gnome-base/gnome-session Available versions: 2.32.1-r2 2.32.1-r3 (~)3.2.1 {debug doc elibc_FreeBSD ipv6} Installed versions: 3.2.1(12.02.18 2011-12-20)(-doc -elibc_FreeBSD -ipv6) Reproducible: Always Steps to Reproduce: 1.

I can confirm this bug.
If you are launching /usr/bin/gnome-session with the --debug argument, this is expected behavior. To check what command line was used to launch gnome-session, you can use the following: # for p in $(pgrep gnome-session); \ do cat /proc/${p}/cmdline | sed -e 's:\o000: :' -e 's:$:\n:' ; done
Hi. Using your line to check the gnome-session's command line gives: $ for p in $(pgrep gnome-session); \ > do cat /proc/${p}/cmdline | sed -e 's:\o000: :' -e 's:$:\n:' ; done gnome-session Should it be related with compile time flags?
(In reply to comment #4) > Should it be related with compile time flags? No; as far as I can tell, at least for gnome-session-3.2.1, debug mode should be controlled purely by the --debug flag at runtime. Please attach your *complete* ~/.xsession_errors log file (compress it if it's too large; also, you may want to check whether there is any private/confidential data in it.)
Created attachment 300313 [details] DEBUG messages in syslog In my case, the messages are going into /var/log/messages. While it doesn't makes sense for an user session, it seems to be related to the gnome-shell process started by GDM. I'm attaching a grep from the /var/log/messages file from my last login.
(In reply to comment #6) Then your issue is different from the OP. Gdm launches its greeter using /usr/bin/gnome-session -f --debug, which is again as intended, because it makes it feasible to diagnose strange gdm login problems. The issue is that all logs from gdm's gnome-session are supposed to be going to /var/log/gdm/:0-greeter.log, not to /var/log/messages. Please attach "emerge --info gdm". Are you using systemd (and if so, what version)? Which system logger are you using (e.g. app-admin/syslog-ng)? Have you customized its configuration in any way?
Created attachment 300315 [details] emerge --info gdm I'm using systemd and syslog-ng. Attached you'll find the emerge --info gdm. The latest snippet of emerge --info systemd is the following: sys-apps/systemd-38-r1 was built with the following: USE="acl gtk lzma (multilib) pam plymouth tcpd -audit -cryptsetup (-selinux)"
This might be either a systemd bug or a misconfiguration in gdm's /lib/systemd/system/gdm.service file. Added systemd team to the CC list, maybe they can help figure this out.
I'm starting Gnome via GDM as well. root@skare$ emerge --info gdm ================================================================= Package Settings ================================================================= gnome-base/gdm-3.2.1.1-r2 was built with the following: USE="consolekit fallback gnome-keyring gnome-shell introspection (multilib) tcpd xinerama xklavier -accessibility -debug -fprint -ipv6 (-selinux) -smartcard -test" root@skare$ for p in $(pgrep gnome-session); \ > do cat /proc/${p}/cmdline | sed -e 's:\o000: :' -e 's:$:\n:' ; done gnome-session root@skare$ ll /var/log/gdm/\:0-greeter.log -rw-r--r-- 1 gdm gdm 31K 29 jan 18.31 /var/log/gdm/:0-greeter.log Seems like it's printing to the :0-greeter.log as well, I've attached the output from it.
Created attachment 300321 [details] greeter log
(In reply to comment #10)(In reply to comment #11) Gdm's gnome-session should be printing verbose debug messages to /var/log/gdm/:0-greeter.log; that is not a problem, it's things working as expected. However, that verbose debug output should not be going to /var/log/messages. If you are seeing the same debug messages in /var/log/messages, please reply to the questions that I asked in the last paragraph of comment #7.
As far as I can tell, it's intended behaviour of gdm to execute gnome-session in debug mode. The problem is in gnome-session, which sends its debug output not only to stderr, but also to syslog. There also is an open bug at https://bugzilla.gnome.org/show_bug.cgi?id=672801
This seems to be fixed now, proposing to close it.
