Hi,
Nvidia Optimus 361.28 manual says:
| Quote: | | Some versions of the “modesetting” driver try to load a sub-module called “glamor”, which conflicts with the NVIDIA GLX implementation. Please ensure that the libglamoregl.so X module is not installed. |
http://us.download.nvidia.com/XFree86/Linux-x86_64/361.28/README/randr14.html
So should I uninstall glamor at all? Or is just case of configuration in Gentoo? Does some use glamor + nvidia optimus in configuration which works?

It looks to me like this would require building xorg-server without the glamor USE flag.
| Code: |
# locate libglamor
/usr/lib64/xorg/modules/libglamoregl.so
# equery b /usr/lib64/xorg/modules/libglamoregl.so

Looks like only xorg-server uses glamor:
| Code: | # equery h glamor
* Searching for USE flag glamor ...
[IP-] [ ] x11-base/xorg-server-1.18.2:0/1.18.2 |
I will try to recompile it without this USE flag and see if nvidia works.
This is my old Xorg.0.log:
| Code: | [ 2228.295] (II) Loading sub module "glamoregl"
[ 2228.295] (II) LoadModule: "glamoregl"

I got the same error .startx returns a black screen, and closed after a few seconds.
Kernel-4.4.39, nvidia-drivers-375.26, Xorg-server 1.18.4, the Xorg.0.log says:
| Code: |
[ 2228.304] (EE) modeset(G0): eglInitialize() failed
[ 2228.305] (EE) modeset(G0): glamor initialization failed
|
I believe we should rebuild xorg-server without glamor USE, or try to use xorg-server1.17.
Any one who have already solved this problem?
