lshw -C display shows UNCLAIMED for GT840M graphics card
Solution 1
Secure Boot does not let the nvidia
module load.
Disable Secure boot in BIOS and it should be solved.
You can see this question for more information.
Solution 2
display UNCLAIMED
can also mean a hardware problem. Especially if the problems started without any software updates.

I've tried everyway to install drivers for NVIDIA and get it working but my laptop still insist on using Intel Haswell integrated GPU.
Here's a what I've tried so far:
First I've tried to install latest drivers from graphics-driers PPA:
sudo apt-add-repository ppa:graphics-drivers/ppa sudo apt-get update sudo apt-get install nvidia-367
I was hoping that it could get my graphics card to work but it didn't.
Then I downloaded
.run
file from offical nVidia website but this installer gives me "The distribution-provided pre-install script failed!" error. Still don't know why it gives me such error.Last thing I tried was after installing nvidia-367:
sudo apt-get install nvidia-prime sudo prime-select nvidia reboot
As you can guess, it didn't work either.
sudo lshw -C display
command gives me following output:*-display description: VGA compatible controller product: Haswell-ULT Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 0b width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:43 memory:b5000000-b53fffff memory:c0000000-cfffffff ioport:6000(size=64) *-display UNCLAIMED description: 3D controller product: GM108M [GeForce 840M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:0a:00.0 version: a2 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:b3000000-b3ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:3000(size=128)
I'm using Ubuntu 16.04 and my graphics card is nVidia GT 840M

Pilot6 almost 8 yearsYou probably need to disable Secure Boot in BIOS.

Juanito almost 3 yearsWell, I'm working with a similar issue and trying to blacklist the wrong driver, may be this may help you if the issue still stands: docs.fedoraproject.org/en-US/Fedora/17/html/Installation_Guide/…
