CentOS - Jul 2011 - centos6 not using /etc/gdm/custom.conf

In CentOS5 you were able to create a server section in /etc/gdm/custom.conf such
as

[server-Standard]
name=Standard server
command=/usr/bin/Xorg -br -audit 4 -s 15 
chooser=false 
handled=true
flexible=true
priority=0

After this change, Xorg would run with the -br -audit 4 -s 15 options. 

Unfortunately in CentOS6 this is not the case. It completely ignores anything
put into custom.conf as far as I can tell.  It appears to run with -nr -verbose
-auth -nolisten tcp by default.  Is there any way to modify this?

Regards,

Stephen Jamieson

There are some gdm settings in gconf-editor (yum install gconf-editor and run it
as root) but I don't know how comprehensive they are.

I just installed CentOS 6 on Monday and at least the daemon section was honored:
I have this:
[daemon]
AutomaticLoginEnable=True
AutomaticLogin=mythtv
TimedLoginEnable=true
TimedLogin=mythtv
TimedLoginDelay=30

And my MythTV account logs in without delay on boot and after 30
seconds if you logout and leave the console idle.

In later Fedora releases, GDM has become less and less functional:
configurability has been removed, more so as releases occur. From my
(known to be flaky) memory, that includes the ability to turn off the
silly list that exposes usernames right on the login screen, the ability
to assign your own wallpaper to the login screen, among other things.

In some releases you can hack your way around whatever the missing
feature is that you're missing by using gconf-editor, in others you
can't.

So, my guess is that RHEL/Centos 6 has inherited the later Gnome
"features" that have removed the feature you want.

Those options are no longer supported in GDM. I think that they were
removed with GDM 2.24 (at the latest, probably 2.22) and C6 is running
GDM 2.30.

You can use

[security]
DisallowTCP=false

in "/etc/gdm/custom.conf" to override the "-nolisten tcp"
but I have
no idea about "-br -audit 4 -s 15".

"chooser=false" and "handled=true" are the default (as far
as I
remember what they stand for!); no idea about "flexible=true" (I
can't
remember what it stands is for!).

That is unfortunate... I suppose I will just have to ignore this issue
then.

Thanks for your help.  I really wish someone know where I could edit
those parameters.

Using gdm is getting harder and harder but you can try:

gconftool-2 --direct \
  --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults \
  --type bool --set /apps/gdm/simple-greeter/disable_user_list true

There are many features available via gconftool-2 or gconf-editor only.

Some are only available if you run them as the right user, as well.  If I'm
not mistaken, for gdm that would be the user 'gdm'.  So you need to run
that above as user gdm with su -c $command gdm or similar.

Thanks for the full syntax; even though this is one of the first things I do on
all new installs (whether CentOS, Fedora, or even Ubuntu; anything using gdm), I
always seem to have to look it up.... and Akemi's page is one of my
bookmarks for that reason....

Since my normal use machine runs KDE, and I use KDM on it, it's not
something that I have to deal with on my own box....

much of this functionality has moved into the gconf2 stuff so you use gconf2 to
disable things like user visibility and such things

If anyone really needs to do this, there is a patch in the gdm srpm
called plymoth.patch that changes the parameters.  It's located on line
225.  If you change that to what you need and recompile it, it should
work.  Not that I recommend this...
