Bug Description

SRU Request:

[Impact]
A recent security update of the nvidia driver provided new EGL libraries and new kernel modules (such as nvidia-modeset and nvidia-drm), which are not handled by the current gpu-manager (ubuntu-drivers-common) and nvidia-prime in 14.04. This problem is fixed in Xenial or newer.

ubuntu-drivers-common also does not distinguish between the different LTS stacks, and this is a major problem on Intel+Nvidia hybrid systems, as anything running stacks older than 14.04.5 will require using the intel driver with SNA acceleration, whereas the rest should use the modesetting driver. Boot parameters can also be passed to use other driver combinations (for unsupported use cases).

[Test Case]
1) Enable the trusty-proposed repository, and install the ubuntu-drivers-common and the nvidia-prime packages.

2) Install the nvidia driver.

3) Restart the system and see if it boots correctly. If unsure, please attach your /var/log/gpu-manager.log and /var/log/Xorg.0.log

[Regression Potential]
Low, the above mentioned changes are already in Yakkety (and most of them have been in Xenial since its release).

This bug was fixed in the package nvidia-prime - 0.6.2.1

---------------
nvidia-prime (0.6.2.1) trusty-proposed; urgency=medium

  * debian/postrm.in, prime-select: backport from yakkety's 0.8.4:
    - Add support for EGL alternatives (LP: #1642662).
    - Simplify the logic for enablement by getting rid of legacy code
      that is only relevant to Ubuntu <= 12.04. This is now possible
      thanks to the fact that we allow installing only one binary
      driver at the time.
    - Do not try to remove the old xorg.conf.

      Also detect the new amdgpu driver.
    - Leave gdm support disabled, since gdm is still missing a patch.

Are you using a pre-installed image or standard Ubunutu?
Please provide your Ubuntu version by "lsb_release -a"
This fix is for Trusty. If you are running Xenial, please file a new bug against your issue.

This is standard Ubuntu 14.04.05 LTS.

For some reason the Nvidia driver doesn't create the egl group for my computer, for example:

$ update-alternatives --config x86_64-linux-gnu_egl_conf
There are 2 choices for the alternative x86_64-linux-gnu_egl_conf (providing /etc/ld.so.conf.d/x86_64-linux-gnu_EGL.conf).

  Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/lib/x86_64-linux-gnu/mesa-egl/ld.so.conf 500 auto mode
  1 /usr/lib/x86_64-linux-gnu/libhybris-egl/ld.so.conf 400 manual mode
  2 /usr/lib/x86_64-linux-gnu/mesa-egl/ld.so.conf 500 manual mode

However the gl group is normal:

$ update-alternatives --config x86_64-linux-gnu_gl_conf
There are 3 choices for the alternative x86_64-linux-gnu_gl_conf (providing /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf).

  Selection Path Priority Status
------------------------------------------------------------
  0 /usr/lib/nvidia-370/ld.so.conf 8604 auto mode
* 1 /usr/lib/nvidia-370-prime/ld.so.conf 8603 manual mode
  2 /usr/lib/nvidia-370/ld.so.conf 8604 manual mode
  3 /usr/lib/x86_64-linux-gnu/mesa/ld.so.conf 500 manual mode

That's why this update broke my Optimus and I am stuck in Intel mode. Like I said it's a Nvidia Quadro K3100M system which is not quite common. Could that be related?
