I analyzed the problem and found the culprit Each time a window manager is (re)started, due to the conf file /etc/init/gpu-manager.conf , the program 'gpu-manager' is called. This program does not like my NVIDIA card, so it calls "update-alternatives" to force X11 to use mesa drivers and libs, even though NVIDIA drivers and libs are installed
TO "solve" the problem I moved away the culprit # mv /usr/bin/gpu-manager /usr/bin/gpu-manager~~ and used # update-alternatives --config i386-linux-gnu_egl_conf # update-alternatives --config i386-linux-gnu_gl_conf and then restarted .the system Now it works as a charm, getting superb framerates in games etc etc. Some more info I have a card NVIDIA Corporation GK208 [GeForce GT 730] I installed Ubuntu xenial I am running kernel 4.8.0-41-generic gpu-manager is part of ubuntu-drivers-common 1:0.4.17.2 I attach the log of gpu-manager ** Attachment added: "log of gpu-manager" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-367/+bug/1665581/+attachment/4834000/+files/gpu-manager.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-367 in Ubuntu. https://bugs.launchpad.net/bugs/1665581 Title: Xorg cannot use nvidia, missing symlink Status in nvidia-graphics-drivers-367 package in Ubuntu: Confirmed Bug description: hi I used the automated GUI tool to select the proprietary driver nvidia-367 but Xorg was not using the nvidia driver, claiming that [ 11.041] (II) LoadModule: "nvidia" [ 11.045] (WW) Warning, couldn't open module nvidia [ 11.045] (II) UnloadModule: "nvidia" [ 11.045] (II) Unloading nvidia [ 11.045] (EE) Failed to load module "nvidia" (module does not exist, 0) To solve the problem, I # ln -s /usr/lib/nvidia-367/xorg/nvidia_drv.so /usr/lib/xorg/modules/drivers now Xorg find the driver and it works fine.
