I recently installed Ubuntu 14.04 on my Dell 3XXX and ran sudo lshw too make sure everything works I noticed that my GT 840M was coming back UNCLAIMED when running

Code:

sudo lshw

So I installed Synaptic Package Manager and installed the latest drivers but it still comes back UNCLAIMED, has anyone got a solution to this?

do you have an actual problem or are you simply curious about the phrase "unclaimed"?

if the first, please explain & show us the problem with as much relevant terminal output as you can.

It is a problem because it causes certain applications to lock my whole system up. From the research I have done all I can tell is that my kernel doesn't recognise the driver for some reason. My aim is to actually be using my graphics card.

What other information is required?

how many graphic cards do you have (you cannot not be using your graphic card, or at least one of them).

please post output of:

Code:

lspci| grep -i vga
sudo cat /var/log/Xorg.0.log | grep  '(EE)'
lsmod
