When I was troubleshooting an Xorg problem, I came across solutions telling me to set the greeter such as:
greeter-session=unity-greeter
But I am unable to understand:
I don't want anyone to be able to shut down my computer from the login screen. Can I remove the shutdown button at the top right corner of the login screen in Ubuntu 12.04?
In Precise (12.04), when I login to lightdm, using the unity-greeter, there's a white circle by my name. For the standard DEs like Unity or XFCE, the circle has a representative icon (Ubuntu symbol or little mouse resp.). I have a session for Awesome window manager which was added when I installed Awesome, but it just shows a blank white circle. I'd like to know how to add an icon to it, or at least some indicator, as unity-greeter doesn't show you what session is set until you click on the circle.
I found another question about changing the session names. The answer for it said to change the names in the desktop files in /usr/share/xsessions. Unfortunately, while there is an icon field in those desktop files, they are all blank (Caveat: I no longer have Unity installed, so maybe the Unity one would not be blank. But the Xubuntu desktop file has it blank even though the icon shows in unity-greeter).
Update: Here's the png I use as a badge for Awesome. It's not great, but looks reasonably nice: [

In 11.10 I used 'gdmflexiserver -xnest' to switch users without logging out however I think gdm has now been completely removed.
I'm trying to bind a keyboard shortcut to do the equivalent of 'Me Menu>Switch User Account...'.
How can I invoke a user switch in 12.04?
I don't want to expose my wallpaper to other people who share my computer, is there a way I can disable this feature or work around it?
