I have the Mirror Displays enabled on my Linux Mint 15 Cinnamon 64-bit box, which has a GTX 680 graphics card installed with recommended drivers. I selected the top green one in this screenshot.

However, when on the login screen, the display is not mirrored; it's displayed on the primary monitor only.

I really would like to have the WebGL clouds (the flyover one) MDM login screen projected on a 108″ screen before login. Is there any way I could do this?

---

Edits for updates:

I notice that the Mirror Displays setting is account-specific. Is there a "default" user at the login screen whose settings I could tweak to enable this? I've tried sudo su -l mdm in an attempt to cinnamon-settings the display to mirrored, but sudo su -l mdm has no effect (very strangely): I retain my shell prompt, and a single exit kills the terminal.

  In Mint, I go to the new Driver Manager, and it asks which drivers I want for the 680. One has the text "(recommended)" in green.

  I chose the driver with the "recommended" text on it. I'm not at the box right now, but it appears that the recommended driver for the 680 is the nvidia-310 driver. I changed it from the default nouveau driver to the recommended driver.

I recently wanted to change the screen resolution in the Ubuntu login screen, and ran across this:

https://askubuntu.com/questions/73804/wrong-login-screen-resolution

Basically, lightdm has a config file, /etc/lightdm/lightdm.conf, and you can use the variable display-setup-script to set up a script that can do whatever you like with the resolution, mirroring, etc.

I don't know what login program Mint uses, but does it have a similar option somewhere? I don't know, but I think the NVidia driver understands xrandr, and if it doesn't it may have it's own CLI configuration tool.

Sorry I can't be more helpful.
