@Matty: That should work on most distributions, only the location and contents of the /etc/acpi/lid.sh file may vary.

Wow! Thanks for your tutorial, I’ll try this interesting stuff on my laptop. And any apps do the same work on other Linux OS?

I’ve backported the new version «eject» in my PPA, so if you install the updated package from there (or you already run Jaunty) you can change «[ ! -f /usr/local/bin/ulcdrom ] || /usr/local/bin/ulcdrom -l» to «eject -i 1», and «[ ! -f /usr/local/bin/ulcdrom ] || /usr/local/bin/ulcdrom -u» to «eject -i 0» and you won’t need ulcdrom.

So, this isn’t what I needed. But thanks for the info :).

sudo apt-get install setcd.

setcd -l 0|1

Available in Ubuntu since Dapper.

On the other hand, setcd(1) implies that the locking flag takes effect only when the cdrom device is open (e.g. when a cdrom is mounted). I wonder if Jaunty’s eject/ulcdrom does something different?

it would be really cool if this was in an option in some gui…

ever since I got my new laptop, I keep accidentally ejected it while the lid is closed and its going into my case, or I’m carrying it around, etc

Martijn: Oh, thanks for letting me know about this. However, this option is only available on Jaunty.

From the manpage of eject(1):

-i on|1|off|0
This option controls locking of the hardware eject button. When enabled, the drive will not be ejected when the button is pressed. This is useful when you are carrying a laptop in a bag or case and don’t want it to eject if the button is inadvertently pressed.
