#1019828 — Bug#966557: Blacklist nvidia-modeset and nvidia-drm

Package: bumblebee
Version: 3.2.1-22
Severity: important

With more recent nvidia drivers and Debian packages of 
nvidia-kernel-support, the nvidia-modeset and nvidia-drm modules are 
attempted to be loaded. This causes the driver to always be loaded. 
Locally I've added those two modules to the 
/etc/modprobe.d/bumblebee.conf to blacklist them in addition to the 
currently listed modules.

There is no apparent change in output when running that command. 
Further, I'm only showing two registered alternatives for glx via 
update-alternatives --config glx.

There are 2 choices for the alternative glx (providing /usr/lib/glx).

   Selection    Path                    Priority   Status
------------------------------------------------------------
* 0            /usr/lib/nvidia          100       auto mode
   1            /usr/lib/mesa-diverted   5         manual mode
   2            /usr/lib/nvidia          100       manual mode

I've got a slight clue, what could be wrong here:

The posted update-glx --display glx shows the following line:

/usr/lib/nvidia - priority 100
   slave glx--libGL.so.1-x86_64-linux-gnu: 
/usr/lib/mesa-diverted/x86_64-linux-gnu/libGL.so.1

but none libGLX_nvidia.so.0. From the maintainer-script however having 
at least one of libGL provided by nvidia or libGLX_nvidia present is 
required for the bumblebee alternative to be installed:
        libGL_nvidia_enabler="
                 $(add_multiarch_slave /usr/lib "" libGL.so.1 /usr/lib 
nvidia/)
                 $(add_multiarch_slave /usr/lib "" libGLX_nvidia.so.0 
/usr/lib "")
....
         if echo "$libGL_nvidia_enabler" | grep -q "slave" ; then
                 bumblebee=1
         fi
...
         if [ -n "$bumblebee" ]; then
                 # enable the alternative for GL usage via bumblebee 
(NVIDIA's libGL.so.1 available)
                 update-alternatives --install /usr/lib/glx glx 
/usr/lib/nvidia/bumblebee $prio_bumblebee \
....

I hope this helps to understand what's wrong in this case.

Thanks, I'll comment out the additional blacklist entries and test with 
that package installed. Those lines aren't harmful in any other way that 
I see, but just unexpected from your original response?

In initial testing I installed the additional nvidia metapackage, 
commented out the additional lines in my /etc/modprobe.d/bumblebee.conf, 
regenerated initramfs, and rebooted. That does seem to have worked as 
neither the modeset or drm drivers appear to be loaded automatically.

Updating of the dependencies and/or addition of the additional module 
blacklists as an additional safety check works for me, thanks!
