A bunch of xorg-related packages were bumped today:

Code:
     Wed Dec 31 14:02:21 2014 <<< app-admin/eselect-opengl-1.2.7
     Wed Dec 31 14:02:23 2014 >>> app-admin/eselect-opengl-1.3.1
     Wed Dec 31 14:02:32 2014 <<< x11-proto/glproto-1.4.17
     Wed Dec 31 14:02:33 2014 >>> x11-proto/glproto-1.4.17-r1
     Wed Dec 31 14:08:31 2014 <<< media-libs/mesa-10.3.5
     Wed Dec 31 14:08:32 2014 >>> media-libs/mesa-10.3.5-r1
     Wed Dec 31 14:09:21 2014 <<< x11-base/xorg-server-1.16.2.901
     Wed Dec 31 14:09:23 2014 >>> x11-base/xorg-server-1.16.2.901-r1


After upgrading them 3D acceleration stopped working on my system. I use the binary nvidia driver. Here's my Xorg log: http://pastebin.com/CL7yaQ7s

EDIT: downgraded them, problem didn't go away. Plot thickens. I'm 100% sure I had working acceleration before the upgrade.
EDIT2: manually eselect'ing opengl set nvidia fixed it after the downgrade. With the -r1 versions it still doesn't work.
EDIT3: removed the bits I was wrong about.

I think I found the problem.

After upgrade:
Code:
[     7.037] (II) LoadModule: "glx"
[     7.038] (II) Loading /usr/lib64/xorg/modules/extensions/libglx.so
[     7.109] (II) Module glx: vendor="X.Org Foundation"
[     7.109]    compiled for 1.16.2.901, module version = 1.0.0
[     7.109]    ABI class: X.Org Server Extension, version 8.0
After downgrade:
Code:
[  2899.413] (II) LoadModule: "glx"
[  2899.413] (II) Loading /usr/lib64/xorg/modules/extensions/libglx.so
[  2899.418] (II) Module glx: vendor="NVIDIA Corporation"
[  2899.418]    compiled for 4.0.2, module version = 1.0.0
[  2899.418]    Module class: X.Org Server Extension
[  2899.418] (II) NVIDIA GLX Module  346.22  Tue Dec  2 10:20:26 PST 2014

peter4,

Code:
[     7.109] (II) Module glx: vendor="X.Org Foundation"

suggests that eselect opengl set is pointing to the wrong OpenGL driver.

I posted an update on bugzilla - had almost the same issue today.
It seems that after update Xorg lost the list of directories to look in for modules. First it tried to load a 32-bit version of libglx.so, then could not find fglrx. Reverting to old versions, reemerging, eselect etc. did not help.
I "fixed" it by putting a list of appropriate directories to xorg.conf, although it was working without this section just fine prior to upgrade.
Code:

Section "Files"
        ModulePath      "/usr/lib64/xorg/modules,/usr/lib64/opengl/ati,/usr/lib32/xorg/modules,/usr/lib32/opengl/ati"
EndSection

(I guess the /lib32/ are not needed)

I wonder what went wrong and what's the proper way of configuring this?

I've had the ModulePath line for a long time my config file, perhaps because I added lots of FontPath lines to that section.

Though I chose not to upgrade to those versions just yet.

I downgraded too and got it working again...don't have time to fiddle with it now. May tinker some more when I get some time. I'm not sure exactly what the cause is yet.

Another but temporary method is
replace libglx.so with

lrwxrwxrwx 1 root root 50 Jan 1 20:19 libglx.so -> ../../../opengl/nvidia/extensions/libglx.so.346.22
-rwxr-xr-x 1 root root 281752 Jan 1 16:54 libglx.so.xorg



( check if in /etc/env.d exists file 000opengl )

Its temp solutions, waiting for xorg-server patch.

(I guess the /lib32/ are not needed)

I wonder what went wrong and what's the proper way of configuring this?

I use FGLRX in Gentoo ~amd64 multilib. I'm emerging world at the moment, so have not rebooted yet. In my case, I notice that my existing xorg.conf has had the following additional lines added to it:

Code:
Section "Files"
EndSection

and there is a new directory /etc/X11/xorg.conf.d/ which contains a new file 20opengl.conf containing the following lines:

Code:
Section "Files"
        ModulePath "/usr/lib32/xorg/modules"
        ModulePath "/usr/lib64/opengl/ati"
        ModulePath "/usr/lib64/xorg/modules"
EndSection

If I read Gentoo Bug Report No. 534128 correctly, all I need to do is comment out the above-mentioned two new lines in xorg.conf. As I am using ~amd64 multilib, I assume I also need to comment out the first ModulePath line in the new file 20opengl.conf but am not sure. Can anyone advise? Thanks in advance.

----------------------------------------------------------------------------

EDIT (Tue 20 Jan 23:17:29 GMT 2015): Just to confirm, I'm using ~amd64 multilib and FGLRX driver (ATI Mobility Radeon HD 5650 GPU). I deleted the above-mentioned two lines in xorg.conf and I also deleted the line containing "lib32" in 20opengl.conf. After rebooting, X11, GLX and Direct Rendering are working.


EDIT (Mon 26 Jan 04:15:37 GMT 2015): Actually, I'm not so sure now that the above-mentioned two lines in xorg.conf were new; they may have been in the file before I emerged world. Anyway, I deleted them.

Adding
Code:
ModulePath "/usr/lib64/opengl/nvidia,/usr/lib64/xorg/modules"

In the otherwise empty "Files" section of xorg.conf fixed my problems.
