What does display UNCLAIMED mean?

Question

Having added a second video card to my computer I am having difficulties getting it to work. I have connected a television to this second video card, but I don't get any signal on the television.

Searching the internet I came across this command:

sudo lshw -C video

This is the result:

*-display

*-display UNCLAIMED

So now my question is, what does display UNCLAIMED mean?

Solution

It means that the system cannot find an appropriate driver for the device (i.e. no driver is 'claiming' it) - it should be supported by the S3 legacy driver, so I'm not sure why that would be the case.
