These links are actually controlled by the alternatives mechanism. You can set the right one using: sudo update-alternatives --auto x86_64-linux-gnu_gl_conf It should set it to automatically follow nvidia's settings and should be valid after updates as well. You can get more info using: cyryl@dagrey:/etc/ld.so.conf.d$ sudo update-alternatives ...

Optimus is a technology from nVidia that allows you to switch between the lower power Intel graphics that are integrated in your CPU and the higher power nVidia graphics from your discrete graphics card. The big difference between Optimus and other strategies is that even when using the discrete card to do the computations, it still pipes the actual display ...

It seems that for Ubuntu 14.04 there is native NVIDIA support for Optimus - named Prime: http://www.webupd8.org/2013/12/more-work-to-support-nvidia-optimus.html There is also some indicator app to help the process: http://www.webupd8.org/2014/01/prime-indicator-lets-you-quickly-switch.html So, instead of configuring applications lists you could just ...

The file you need to patch is stored in /usr/src/nvidia-??/nv-acpi.c (in my system with nvidia-331 the path is /usr/src/nvidia-331-331.38/nv-acpi.c). The driver per se is closed source but this file belongs to the driver/kernel interaction. As you have both 304 and 304-updates, make sure you patch the one Bumblebee uses (in doubt patch both). Then to ...

New Intel driver is the problem. Nvidia doesn't support new drm environment. To remove the new driver run the following commands: sudo apt-get purge i915-3.15-3.13-dkms sudo apt-get install --reinstall xserver-xorg-video-intel libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core sudo dpkg-reconfigure xserver-xorg Then restart the system. optirun should work ...

I am not a bumblebee user but my understanding is that bumblebee is using the nvidia proprietary driver which implies that lmsensors will no more handle the temperature of the nvidia gpu. See http://packages.ubuntu.com/trusty/utils/bumblebee-nvidia, it depends on the NVidia proprietary driver. If I am right, you can read the temperature of the NVidia chip ...
