Bug#900248: Direct Render problem
Yes---the change in xorg caused the problem. I linked the nvidia libglx.so from /usr/lib/xorg/modules/linux/ to /usr/lib/xorg/modules/extensions/ (renamed the libglx.so in /extensions to libglx.so.bak). Restarted my system & now have direct rendering. dean@debian:~$ glxinfo | grep OpenGL OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GTX 960/PCIe/SSE2 OpenGL core profile version string: 4.6.0 NVIDIA 390.59 OpenGL core profile shading language version string: 4.60 NVIDIA OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 4.6.0 NVIDIA 390.59 OpenGL shading language version string: 4.60 NVIDIA OpenGL context flags: (none) OpenGL profile mask: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 390.59 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20 OpenGL ES profile extensions: That is a "temporary" fix that works.
Bug#900248: Direct Render problem
Greetingstwo more of us have commented on this bug. I have a fully updated install & am experiencing this problem (nothing pinned). I have posted the nvidia-bug-report via a google drive link in the bug report. Still running 390.59-1, the system works with no GL apps working properly. Cairo Dock shows artifacts during animations. GLXGears looks "normal" (several 100fps low). My baseline game (Linux version of UT2004) runs at about 10~15fps. All newer games run about 1~2fps. I have not reverted back--am able to test if more information is needed. -- Cheers!!! Dean Loros Performance by Design Ltd. autocrosser at http://forums.linuxmint.com
