So I just installed Ubuntu, and I love it. I don't think it's going to replace Windows 7 for me, and it has a few problems that I'm probably going to end up fixing when I figure out how to use WINE, but it's still awesome.

My main problem now is that whenever I put Ubuntu in to suspend, the entire thing freezes. The monitor is still on, but is only black, and there is no reaction to any buttons.

While I don't mind pressing Shut Down since Ubuntu loads up rather fast in comparison to Windows 7, it can get annoying and inconvenient.

Thanks for any help!

OK after a bit of work I modified the scrips above from the other suggestions. Thank you @wangdw! Here is the following bad ass script (don't forget as before to create a file using sudo gedit /etc/pm/sleep.d/20_custom-ehci_hcd and also to set the read permissions using sudo chmod 755 /etc/pm/sleep.d/20_custom-ehci_hcd):

I've been experiencing the same problem. It seems that Ubuntu attempts to suspend itself but some hardware doesn't want to comply. Here are some repairs that might work:

1. open a terminal by holding ctrl+alt+t;
2. type: sudo gedit /etc/pm/sleep.d/20_custom-suspend;
3. press Enter and authenticate;
4. put the following text into the created file; save it and exit. 
5. reboot and see if it works.

This little script comes from somewhere on the Internet but I cannot find the source...

EHCI_BUSES="0000:00:1a.0 0000:00:1d.0"
case "${1}" in
    hibernate|suspend)
        # Switch USB buses off
        for bus in $EHCI_BUSES; do
            echo -n $bus > /sys/bus/pci/drivers/ehci_hcd/unbind
        done
        ;;
    resume|thaw)
        # Switch USB buses back on
        for bus in $EHCI_BUSES; do
            echo -n $bus > /sys/bus/pci/drivers/ehci_hcd/bind
        done
        ;;
esac

Please try this out and tell me your findings!

If that script doesn't work, you might want to try another:

I found that installing the "dell firmware addon" package fixed the issue during the development cycle.
