How to change gdm theme with fedora 15

[aboe76]

This guide will explain how you can change you're gdm gtk3 theme with fedora 15

prerequisite: gnome-tweak-tool and a terminal (gnome-terminal)

Open gnome-terminal:

su -
( insert password)

Now we are root and the first step is to install gnome-tweak-tool
if you already did this skip this.

Install gnome-tweak-tool

yum install gnome-tweak-tool

Now we make the gdm user available to make changes:

# xhost +SI:localuser:gdm

If you did this right you get this message:

localuser:gdm being added to access control list

Next we will fire up gnome-tweak-tool

# sudo -u gdm gnome-tweak-tool

This will start gnome-tweak-tool as the user gdm (sudo -u username will start the application as designated user)

Now we can change the interface gtk+theme, icon theme and cursor theme to whatever you like.
Don't forget to change windows current theme to what you want.

How to change gdm login background:

# sudo -u gdm gnome-control-center

Here you can change the background

And when you're done exit the gnome-tweak-tool or gnome-control-center and type:

# exit

(ps the # sign is the sign you're running the command as ROOT don't copy it!!

This guide has been made thanks to www.archlinux.org fine wiki about gdm.

i can't run this command :

$ sudo -u gdm gnome-tweak-tool
sudo: gnome-tweak-tool: command not found

how did this will work?
because gnome tweak tool is not an install application,only like a portable?

I've try this in dir gnome twaek tool :

$ sudo -u gdm ./gnome-tweak-tool
Gtk-Message: Failed to load module "pk-gtk-module"
Traceback (most recent call last):
  File "./gnome-tweak-tool", line 84, in <module>
    MainWindow()
  File "./gnome-tweak-tool", line 33, in __init__
    assert(os.path.exists(gtweak.PKG_DATA_DIR))
AssertionError

I can see you're problem,

First become root with "su -"
second step:
install gnome-tweak-tool
"yum install gnome-tweak-tool"

then become gdm "xhost +SI:localuser:gdm"

and last run the command again.
ps, if you copy paste it, without the " please

i think it is about changing GTK theme and not GDM theme !

Hi...

Thanks for the guide. A quick question...

In one step you instruct:

# sudo -u gdm gnome-tweak-tool

I was under the impression that running a sudo command as root can cause problems. Am I mistaken?

Also... I understand that fedoras equivalent of gksudo is beesu when loading up a graphical command. Would it be better to do this using beesu? I looked through the man and found no equivalent for a -u suffix to tell it what user to load...

Very nice, works perfectly!

Could anybody help me to fix the error as below?

When I executed the command " gdm gnome-tweak-tool" ,my terminal feeback the following problem.

** (gdm-binary:2807): WARNING **: Failed to acquire org.gnome.DisplayManager

** (gdm-binary:2807): WARNING **: Could not acquire name; bailing out

This is a great post! for a long time to be able to edit the GDM theme has not been accessible. This is a great work around.
That being said what file or files are being edited when the commands "sudo -u gdm gnome-tweak-tool" and "sudo -u gdm gnome-control-center" are used?
For example way back when before they disabled editing the GDM one could go in and edit an xml file to create a custom GDM theme. What file or files are being edited with the gnome-tweal-tool and gnome-control-center?

You can change things like laptop brightness in GDM with dconf-editor, as well.

Thank you for the tip!
I'm using Xfce so I use dconf-editor to change the GDM settings.
There are useful options under org.gnome.gnome-settings-daemon.plugins, like font hinting (Xsettings) (MS fonts like 'Slight', not the default 'Medium') or power button actions. Plus we can disable other stuff that don't make sense to have in GDM (don't know if it makes any difference, though).

using sudo as root is no problem, because sudo -u is the command. the -u gives you momentarily the ability to perform the command as the specified user afterwards.

so sudo -u gdm results in using the command as the user gdm without the need of giving the gdm user a login/password.
