I'm in fluxbox on Arch on a Macbook 5,1. New to linux. I'm trying to get Arch to suspend when I close my laptop. Lately I've just been using sudo pm-suspend.

I installed slimlock, and inserted 

button/lid)
    case $3 in
        close)
            #echo "LID switched!">/dev/tty5
         /usr/sbin/pm-suspend &
         DISPLAY=:0.0 su -c - username /usr/bin/slimlock
            ;;

in my /etc/acpi/handler.sh, which I read to do here, but it doesn't work. I tried installing xscreensaver, but I get a weird error: 

error: perl-lwp-mediatypes: signature from "Justin Davis (juster) <jrcd83@gmail.com>" is unknown trust
error: failed to commit transaction (invalid or corrupted package (PGP signature))

Did you try pacman -Syy before trying to install xscreensaver? And what laptop do you have? – mtahmed Sep 4 '12 at 9:35

Follow this: https://wiki.archlinux.org/index.php/Pacman

Being new to Linux and going directly to Arch is not a good idea. Take a look at Fedora/Ubuntu or Debian.

Ps: You need to generate the PGP keys for arch linux so you can add them.

But I was under the impression that installing (or updating pacman) did that automatically... – mtahmed Sep 4 '12 at 18:53
thanks, this helped getting xscreensaver. but that script still isn't running anything on lid close – Jack Stewart Sep 4 '12 at 19:04

@mtahmed Actually it depends on the installation you are using. Last time I installed using the new Arch version, I didn't need to do anything. If you do, you usually need; pacman-key --init ; pacman-key --populate archlinux. JackStewart: I remember having the same problem with XFCE4. I The only way for me to close the lid was telling XFCE4 to suspend and not hibernate. Maybe a hint, perhaps you tried laptop-tools from the repo? wiki.archlinux.org/index.php/Laptop_Mode_Tools – Ephexeve Sep 11 '12 at 10:14

You will need to install archlinux-keyring package to have all needed public key.

pacman -S archlinux-keyring

More information here.

Also you should lock first, suspend later:

button/lid)
    case $3 in
        close)
            #echo "LID switched!">/dev/tty5
            DISPLAY=:0.0 su -c - username /usr/bin/slimlock &
            /usr/sbin/pm-suspend
            ;;
