Since this was driving me quietly insane on F11, I put together the
following patch that, if it's present, reads GDMCONFDIR/excluded, and
excludes any users listed in there.

Nabble is likely to mangle it if I paste it in, so I've put the patch up at
http://www.eridani.co.uk/gdmfix/gdm-2.26.1-excludes.patch - this is against
the latest update for F11.

It probably doesn't conform to the GDM coding style, and is quite an ugly
hack, but it works for me.

Re: f10 gdm user hide

[k12linux]

While this is the hard way to hide accounts, it does work to hide accounts that 
have uids > 500.  If you can just change the uid to something between 100 and 
500 you can avoid all of this.

This is absolutely a hack so you'll have to repeat some of it each time gdm is 
updated.  You should probably read through this whole post and make sure you 
want to go through this much effort before you start.

First, you'll need to have rpm-build and development tools installed.  Easiest 
is probably to do:
# as root yum groupinstall "Development Tools" yum install rpm-build 

Set up an RPM build environment on your PC.  If you don't know how try this:  
Assuming your user name is george...
# As your user account, not root... mkdir /home/george/rpm echo 
"%_topdir   /home/george/rpm" > /home/george/.rpmmacros echo "%dist   
.fc10.george" >> /home/george/.rpmmacros 

Get and install the source rpm.
# This will need to be done each time gdm is updated #again, as your 
user and not as root yumdownloader --source twinkle --destdir /tmp rpm -i 
/tmp/gdm-2.24.1-4.fc10.src.rpm # (assuming that version # is still current)

Check if you have all of the packages needed to build your own version of gdm:
rpmbuild -bp /home/george/rpm/SPECS/gdm.spec
If you are missing any it will tell you.  You'll have to install them in order 
to build your own gdm which hides accounts.

Create and edit ~/rpm/SOURCES/gdm-2.24.1-hide-user.patch using this text as a 
template:
--- gdm-2.24.1-orig/gui/simple-greeter/gdm-user-manager.c 2009-04-08

 "rpm","nfsnobody", 
 "pcap",+  
"hideuser",   NULL }struct 
GdmUserManagerPrivate

Replace "hideuser" with the user name you want to hide.  If you want to hide 
multiple users, do two things... add more lines like the one for "hideuser" and 
2nd, edit the string @@ -95,6 +95,7 @@ and add one to the 7 for each extra

@@ -95,6 +95,10 @@

EVERYTHING FROM HERE DOWN WILL NEED TO BE DONE EACH TIME YOU UPDATE GDM AND 
YOUR HIDDEN USER ACCOUNTS RE-APPEAR AT LOGIN.

Next edit the gdm.spec (in ~/rpm/SOURCES) and:
* At around line 90 there will be several lines starting with Patch##.  Add 
your own between Patch14 and Patch99 like:
Patch40:gdm-2.24.1-hide-user.patch
* At about line 115 are several lines starting with %patch.  Add your own 
between %patch14 and %patch99 like:
%patch40 -p1 -b .hide-user

Save your updated .spec file and build your new gdm .rpm. 
# as your user account and not as root rpmbuild -ba ~/rpm/SPECS/gdm.spec

If all goes well you'll have an installable rpm under ~/rpm/RPMS/i386 now.  
Install as root:
su -c "rpm -Uvh 
/home/george/rpm/RPMS/i386/gdm-2.24.1-4.fc10.george.i386.rpm"

 I'd suggest trying KDM, which can actually be configured.

 su -
 yum install kdebase-workspace
 echo 'DISPLAYMANAGER="KDE"' >/etc/sysconfig/desktop
 reboot

 (That's really "KDE" there, not "KDM".)
 If you want to make sure GNOME is the default desktop, you can add:
 echo 'DESKTOP="GNOME"' >>/etc/sysconfig/desktop
 Likewise, DESKTOP="KDE" makes KDE the systemwide default.

 Then you can set up KDM through systemsettings (the KDE configuration 
 tool).

 You may lose some GNOME integration though (e.g. fast user switching),
 because obviously KDM was primarily designed for KDE.

You should be fine.   Adding a pseudo user with a UID less
than 500 and greater than 100 is fine.  Even smolt and pulseaudio does
it.

As for top posting... that can cause you much more pain.

Why is uid/gid 350 bad? [WAS: Re: f10 gdm user hide]

[Morgan Read]

Hi Folks

I've just set up a user account for our scanner - no the scanner will
never login at GDM (will ftp in).  So, after much gnashing of teeth,
I've given it a uid/gid of 350 so that it doesn't show up in the GDM
login (it seem the only way to hid a user account is to give it a
uid/gid below 500).  How long before this rash move turns my machine
into a smoking pile of ash?

Thanks all,
Morgan.

Turns out to have been a false alarm.  Mikkel was looking at a F8 machine,
which has gdmsetup and, of course, F9 and F10 don't.

Scaling back my question again, does anyone know how to set the default
username that is initially selected when gdm starts?  So if it's Fred's machine
he doesn't always have to move the pointer off of Sally first before he logs
in.

I don't have that.  My System-Administration menu goes right from "Logical

Window-Users run?

I don't know how to sort them - it looks like they are by uid. But
to select what users are displayed, try System --> Administration
