Posted: Wed Apr 08, 2015 6:03 pm Post subject: Nouveau, "KMS not enabled" when it should be |
|
|
I just upgraded my GTX 460 GPU to a GTX 960. I had to hunt down some answers to make the nvidia driver go away after installing nouveau. Now I'm at the point where the nvidia driver is gone, but no matter what I do, Xorg.0.log says that KMS is not enabled, even though I've enabled nouveau in the kernel both as a module and compiled-in (not at the same time, obviously. I tried one, then the other, but it makes no difference here).
I am stuck. What exactly do I need to do to make nouveau work and get KMS going?
EDIT:
Just learned this chipset is simply not supported before kernel 4.0 rc. _________________ decibel Linux: https://decibellinux.org

...IIRC, CONFIG_FB_VESA should actually be not set. |

@VoidMage, thanks for this hint, it boots a second faster. VoidMage wrote: | ...IIRC, CONFIG_FB_VESA should actually be not set. | Tried nvidiafb but got me:
