Pre-setup
When you run K3b for the first time, you may find K3b informing you that no optical writer drivers have been found, meaning you will not be able to write to any optical discs. There is no need to panic as K3b will open the Permissions tab on the Programs page of the configuration dialog, where permissions can now be changed. In all modern systems optical devices belongs to a certain user group (⪚ cdrom). If the current user does not belongs to this group, he is offered to add himself to it on this tab.
