Hi all,

I'm currently using gnome-screensaver to lock my xmonad sessions, but I was wondering if anyone had put together anything like a an integrated lock screen as a replacement.

I don't think it's a good idea (security-wise) to make a lock screen a large program. Here is Jamie Zawinski's argument regarding that point: http://www.jwz.org/xscreensaver/toolkits.html

The reason I want this is that I'd like to extend my lock screen with sound volume and audio pause/play buttons and I *do not want* to try hacking on either gnome-screensaver or xscreensaver.

Full disclaimer: this is my own software, but maybe it will be of use. I wrote a screen locker (metalock, http://chiselapp.com/user/beyert/repository/metalock/) that supports binding arbitrary commands to keys, among other features. It's fairly secure, but I still need to finish a program to invoke it automatically (eg. a better xidle).

If no one has done it, a pointer in the right direction would be appreciated.

I don't know if it would fully address your needs, as it is very small, nor is it written in Haskell, but it isn't a bloated monolithic program like gnome-screensaver or xscreensaver, and is customizable within the context of what it does, unlike the alternatives. Tim
