[SOLVED] Prevent laptop from sleeping when closing lid.

I have installed an NFS server on my laptop, so it's running long times without me directly using it. In order to save space and power, I would like to close the lid.
Basically, all I want it to do is turn of the screen, and not go to sleep. Currently, when closing the lid, it turns of the screen, but also attempts to sleep (which results in a kernel panic).
I read about the ACPI package somewhere, but I guess there's an easier way to turn off this "feature" without having to install ACPI?

Thanks in advance!

No, usually I don't even login locally (only over SSH) and stay at the CLI login screen.

Re: [SOLVED] Prevent laptop from sleeping when closing lid.

On my system HAL is monitoring the lid switch, powerdevil (kde4 power manager) reacts on this and other events from HAL according to what I set in my KDE systemsettings. I think HAL alone doesn't initiate anything, do you have some other powermanager/cpufreq daemon running? Maybe that one is responsible for the suspend action, and you can set it to not do anything on a lid event in some configuration file...

[val@tux ~]$ lshal --monitor

Start monitoring devicelist:
-------------------------------------------------
14:07:01.891: computer_logicaldev_input_2 property button.state.value = true
14:07:01.897: computer_logicaldev_input_2 condition ButtonPressed = lid
14:07:02.128: computer_logicaldev_input_2 property button.state.value = false
14:07:02.134: computer_logicaldev_input_2 condition ButtonPressed = lid

14:07:05.639: computer_logicaldev_input_2 property button.state.value = true
14:07:05.645: computer_logicaldev_input_2 condition ButtonPressed = lid
14:07:05.845: computer_logicaldev_input_2 property button.state.value = false
14:07:05.851: computer_logicaldev_input_2 condition ButtonPressed = lid
