Re: [Trisquel-users] How to disable DVD player in Trisquel?

First, you have to change your udev rules. There is a rule that ejects the  
drive when the button is pressed, and this rule causes problems.
Open /lib/udev/rules.d/60-cdrom_id.rules in a text editor (as root) and  
comment out the line with DISK_EJECT_REQUEST by putting a hash at the  
beginning of the line.

Then, to lock the drive:
$ eject -i 1
And to unlock:
$ eject -i 0
