Apparently, the latest release of Bumblebee has dropped support for the nouveau driver. Installing the latest primus package from the bumblebee repo requires removing bumblebee-nouveau and installing bumblebee- nvidia. I haven't seen an announcement to that effect, but there is a bug report at the Bumblebee repo suggesting that that's the direction they are going.
Is there a good, up to date summary of the state of Optimus support for Linux and Fedora, both open-source and proprietary? Anyone have in- depth experience with Dell (Latitude E6430) implementation and a recommendation for the best way to proceed?
One point in particular: I have a docking station, but I've never been able to get video out when docked. Has anyone succeeded in getting that working?
TIA.

The discussion which lead to that is here: https://github.com/Bumblebee-Project/Bumblebee/issues/773
On my 960m (F24 and 4.6+ kernel required) doing DRI_PRIME=1 ./foo "worked" (as in it used the discrete GPU and performance was moderate) ... it's just limited by the lack of reclocking in the driver for that chipset yet.
If using the proprietary NV driver for optimus then you can follow the Bumblebee wiki page fine, but you have to use the managed repo for a recent driver.
As to video out when docked, sorry I don't have a docking station to test (much less that specific Dell model).
TL;DR: If using nouveau (or modesetting as the direction seems to be going for the FOSS driver) just use PRIME and not bumblebee ... only use bumblebee when using the nv driver.

That's just with a vanilla Fedora install, no Bumblebee, I take it.

Thanks. I will experiment.

I have one of the macbook pro systems with a failed (months after the warranty expired) systemboard that can't use optimus. I have to start X manually to avoid endless crash and reboot loops when an update enables optimus. The internet is sadly lacking in the sort of technical details needed to come up with a robust configuration that doesn't get trashed by updates.

Which video out in which "docking station"? We have various Dell Latitude E6X30 models (but without NVIDIA discrete graphics) and PRO3X docking stations that have 3 output connectors DisplayPort, DVI, VGA), but even on Windows, only the VGA and DVI ever worked, and DVI was problematic. I assumed the DIsplayPort requires the discrete graphics, but Dell SLN115952 indicates that the DVI port on a "E-port Plus Port Replicator" (VGA, two DVI and two DIsplayPort connectors) can be used with Intel HD graphics.

Tangential topic reply: Depending on where you are, and how long ago that was, look into your local office of fair trading, consumer advice bureau, or what yours is called. You may find that manufacturers aren't allowed to limit their warranty as much as they have done.
Over here, in Australia, if a manufacturer says they offer a 2 year warranty, for example, that doesn't mean exactly 2 years. They're obliged to have a reasonable amount of overlap. And the kind of appliance, and its cost, get taken into consideration (what the reasonable lifespan for it should be).
