Impossible to switch user

[tobiasBora]

Hello,

First, excuse me, but I would like to post this bug in xorg-emgd, but I've had an error. So I post it in gdm.

I'm on a computer EEEPC 1101 with ubuntu 11.04 (natty), and view days ago, I've installed xorg-emgd for have a nice resolution. I followed this tutorial (french) to install it :
http://doc.ubuntu-fr.org/poulsbo#ubuntu_1104_natty

Now, my resolution screen is ok, however, now, when I want to switch user, I return to a page witch ask me the password for the current user. Then, I click on "switch user", and... I've my screen saver which appear. Then, I move mouse, and I return in the same page... I don't know if the bug is with emgd or gdm, but it appear after emgd installation.

Do you know how solve it ?

Thanks for solve it,

Tobias BORA

PS : excuse me if I make mistake in my English.
