choosing video card
« on: 2017/06/09, 23:54:24 »
My new laptop has two video cards:

Code: [Select]
$ inxi -G
Graphics:  Card-1: Intel Device 591b
           Card-2: NVIDIA Device 1c8d
           Display Server: X.Org 1.19.3 drivers: modesetting (unloaded: fbdev,vesa)
           Resolution: 1920x1080@60.05hz
           GLX Renderer: Mesa DRI Intel Kabylake GT2 GLX Version: 3.0 Mesa 13.0.6

Which one is it using?  How would I select the nvidia (with nouveau drive), since I assume it would be more efficient.

Here is more info on the system:

This is a tough call, I would wait for towo's answer

The nv card you have I think became supported with 375.10

https://wiki.debian.org/Bumblebee  not sure that will work or not

I either give too many fucks or no fucks at all, it's like I cannot find a middle ground for a moderate fuck distribution, it's like what the fuck

Interesting!

The issue is not a big deal at all to me.  It's working fine (or so it seems, as I haven't used it much yet).  It was more a curiosity.  I am not even sure which one is being used...  But Bumblebee looks very interesting!

What makes you think, nouveau would be more efficient than nvidia blob?
And i would oracle, nouveau would not support your card really, but without an

update-pciids
inxi -G

it's hard to say, if nouveau would support that card initial.

For me bumblebee is a crappy solution, but sadly it's the only available in debian, since the better tool nvidia-prime isn't packaged in debian.

With nouveau you could use dri offloading to activate the nvidia gpu for the choosen application.

All over all i would never buy such optimus hardware.

I din't think it would.  I just thought it would be easier to maintain than the blob (and that having the NVidia card running would be more efficient than having the intel one.)

Thanks for the helpful comments.  I will use this laptop for only a month and a half (on a trip).  It would also not have been my choice.  That's why I said it is not a big deal.  It's working just fine, but made me curious of how these things work now on Linux.

Again, thanks for the replies!
