Layers, properties do not save, can't add objects to them

I want to put a watermark, headers, footers, and other non-data related items on my drawing. However, when I try to create a new layer for this: I can not add anything to it. I hold an object until it flashes and drag it over the layer tab, but the cursor is shown as a circle with a cross going though it. I check the layer properties and check “visable” and “printable” and try it again, same result.

When I open the layer properties again, I notice that all my settings where not saved and everything has been unchecked.

I can work with the original 3 layers just fine, they work as expected. But any custom layers are quite useless.

Are you sure the option “Locked” is not checked? I work on Windows 7 and have no problems with layers.

Yes I am sure. Even then I have no way to be sure… for the settings do not save. I’m using Ubuntu 14.04LTS
