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.

BTW , I have had to apply this fix many times in the past.

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

let me add that the commands
# update-alternatives --auto i386-linux-gnu_egl_conf
# update-alternatives --auto i386-linux-gnu_gl_conf
are more straightforward, and that
# ldconfig
is needed afterwards

Confirm the problem with a nv117 (gtx750) card, both with 365 & 367 drivers (package from graphics-drivers ppa works well)
