ETA for nV GeForce GTX 675M w/2GB
 
Just got a new Clevo (Sager) with the GTX 675M. But it ain't listed in your Linux drivers supported list! (and, needless to say, it isn't working with the current driver).

Any ETA for when the driver will support this chip?

Being in the supported list shouldn't affect whether it works or not. Can you clarify exactly what doesn't work and attach an nvidia-bug-report.log after running into the issue?

Sure! In my experience, new chipsets never work until I go get the latest drivers, so I just assumed I needed to wait for it to appear in the list.

The issue is that the screen flickers like crazy, and never comes to life.

You have several VGA devices in this laptop, so you want a line like this in your xorg.conf Device section:

BusID "PCI:1:0:0"

However, isn't this an Optimus laptop? I don't know if the NVIDIA VGA device has access to the display hardware or not, you might need to go with the Intel driver and use something like Bumblebee or try disabling the Intel VGA device in the SBIOS if such an option is available.

No change. And there is no setting to turn off the Intel hardware in the BIOS. The BIOS says:

VGA Card: nVIDIA GTX 675M

This is the hardware:

I'm quite sure the nVIDIA chipset has access to the display.

FYI: Just noticed that the current driver is .40, but I had been testing with .20. Built the new driver. No change.

Can you attach a new nvidia-bug-report.log after the change you've made?

Attached.

See, now it's finding and initializing the device properly, but not finding any connected monitors. Can you please try getting rid of the ConnectedMonitor "CRT" line in your xorg.conf and attach a new log?

Oh, right. Sorry about that. We have auto-detect logic that adds the CRT line when no display is found. I commented that out. Here is the new log.

To me, it doesn't look like the NVIDIA card is wired to the display in the current state of things, which unfortunately does sometimes happen in Optimus designs. If no amount of changing VGA settings in the BIOS can change that, you'll have to use the Intel driver and setup Bumblebee for OpenGL rendering.

Whereas the internal display freaks out halfway through the boot process, if I connect a monitor to the DisplayPort on the back, I can actually see the whole boot, so I can build my kernel module on this hardware directly (I'd been building on another machine, and copying the drivers).

This allowed me to repeat our experiment with a much cleaner setup. (log attached)

I have the DisplayPort monitor and the internal screen connected. I ran nvidia-xconfig and then tried startx --logverbose 6. That failed. Then I ran nvidia-bug-report.sh.

Since the DisplayPort is undoubtedly wired directly to the daughter card with your chip on it, can you help me to at least get that monitor up and running directly?
