Subject: gdm3: Continuously starts X servers, uses too much CPU time and RAM

Date: Sun, 27 Nov 2011 14:46:17 +0100

Package: gdm3
Version: 3.0.4-4
Severity: important

Dear Maintainer,

Since upgrading to gdm3 3, I've noticed that the gdm3 daemon spends
its time launching X servers; currently I have

     |-gdm-simple-gree---{gdm-simple-gre}
     |-gdm3-+-58*[gdm-simple-slav-+-Xorg]

     |      |                 `-{gdm-simple-sla}
     |      `-{gdm3}

with vast amounts of logs accumuating in /var/log/gdm3 as X servers
are continuously started even though the system has long run out of
VTs.

Currently, with an uptime of 15:48, the root gdm3 process has
accumulated 4:55 of CPU time used, and 603MB of RAM. On a 3GHz Pentium
4 with 3GB of RAM this is rather a lot.

I've previously tried restarting gdm3 and rebooting the whole system,
but the behaviour remains the same.

Do you have any idea what I could do to determine the problem's cause
and/or fix it?

Thanks in advance,

Stephen

Subject: Re: gdm3: Continuously starts X servers, uses too much CPU time and RAM

Date: Sat, 31 Mar 2012 20:42:00 +0200

Package: gdm3
Version: 3.0.4-4
Followup-For: Bug #650183

Dear Maintainer,

I have the same problem. After running an 'apt-get dist-upgrade', with nothing
that looked too significant, I have the same bug. According to
/var/log/Xorg.*.log, X reached 390 connections before giving up. I have
switched to XFCE and lightdm to regain access to my system. Maybe related, even
via lightdm I am still unable to start a Gnome3 session. I have tried purging
GDM3 and reinstalling, to no effect. I also tried restarting gdm and rebooting,
both producing no change.

I don't even know how to investigate further - any suggestions?

Thanks!

  Arthur

I experienced a similar (the same?) issue and eventually got around it 
by upgrading to the latest libgl1-mesa-dri package from sid, 8.0.2-2 
at that time.

Good luck,
Fabian

     + Explicitly disable introspection.
     + (All of this can be shipped in separate packages if actual

     + Add a check for gnome-session, which is also used.
   * 10_gdm3_pam.patch: handle the bucket of FAIL that is hardcoding the
     service name in various places since split authentication was
     introduced.
   * 18_parametrize_create_display.patch,
     19_static_transient_display.patch, 20_switch_kill_greeter.patch,

   * Require dconf 0.12.1-2.
   * gdm3.post{inst,rm}: add a gdm-welcome PAM service, which is now
     needed for the login session. It's just a symlink.
   * 91_shell_version_control.patch: new patch, Debian-specific. Add
     strict version checking for gnome-shell in order to go to the fall
     back session in case of potential incompatibility.
   * 93_private_lib.patch: also install the typelib file in the private
     directory, and drop the gir file.

     fallback session. Otherwise reboot/shutdown does nothing when
     someone is logged on.

Andreas,

We have a new episode that I could document... Spontaneously, the
monitor went into energy save mode. My X session had been terminated and
the GDM/Xorg splurge occurred. Attached are all the files I could think
of immediately.  Sorry if I missed something obvious.

I will have to reboot the machine so it is in a fit state for a Python
training workshop I am presenting next week, so no more episode specific
data I'm afraid.

I'd rather not unless it becomes essential…

I am using the Debian Experimental packages which just got upgraded to
302.17 – which is why I was having another go with the machine.

Hopefully this data contributes something useful.
