I've a DELL XPS 15 with NVidia Optimus tech, and after Ubuntu upgrade it can't recognize my HDMI/DisplayPort anymore.

After connect my HDMI it just doesn't appear in my Display application.

I know that Nvidia property driver is not working completely properly with it, but before the upgrade I could use my second monitor just fine.

I've spent some days trying to get it working but with no success.

Ps: I've installed bumblebee and bumblebee-nvidia, otherwise my X didn't work.

Any thoughts?

1 Answer 1

Same here on a Siemens laptop: without NVidia driver, no HDMI. I circumvented the NVidia driver problem by adding "bleeding edge" drivers (not yet released to the general public)

If that's the route you want to take too, just add the PPA of xorg-edgers (you can roll back to previous drivers if the latest (but not always greatest) doesn't work)
