I want to change the default Login Screen background/theme in Centos 6.3. The INSTALL folder in the theme I downloaded says:

Use 'gdmsetup' to install.

But gdmsetup isn't a recognized command. I installed the latest EPEL repositories and tried a yum install gdmsetup that didn't work.

I did yum list *gdm* and I got this:

[root@localhost BlueSwirl]# yum list *gdm*

I'm not sure what I'm missing or what I need to do. Can anyone tell me how to customize my login screen or use some sort of theme installer to customize it?

Try with yum groupinstall "GNOME Desktop Environment" "X Window System" –  Renju Chandran chingath Sep 19 '13 at 11:46

I have been having the same problem, only on Debian Squeeze with an older kernel (I'm running it on VERY old hardware). I have in the past used an older version of gdmsetup that would allow one to change the login screen, theme, and a few other customizations. Check your version of gnome by typing: gnome-about (in terminal). If you have GNOME 3, others running GNOME 3 have reported that gdmsetup is just gone, not in GNOME 3 at all. I am still technically running GNOME 2.3, but I fear that the lack of choice that came in with GNOME 3.x is bleeding over into the legacy GNOME programs. Now all I get with that command is a lame pop-up window that will only let you choose whether to login automatically, or get shown a list of logins. I have bookmarked this page; if I find out why they punked gdmsetup, I'll report back, but no joy so far. Good Luck! -drachenchen
