Burning with Arch

Sometimes it may be necessary to graant you the necessary permissions:

Setting permissions

Users that should be able to use CD/DVD burning devices must have permissions to access the devices. If you are using udev (which is default in Arch Linux kernels), you only need to add the user(s) to the optical group:

# gpasswd -a  optical

Log out and back in for the changes to take effect.
