** Summary changed: - Handle EGL alternatives and use different drivers for the LTS stacks + SRU request: handle EGL alternatives and use different drivers for the LTS stacks
** Description changed: - A recent security update of the nvidia driver provided new EGL - libraries, 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). ** Description changed: - A recent security update of the nvidia driver provided new EGL libraries - and new kernel modules, which are not handled by the current gpu-manager - (ubuntu-drivers-common) and nvidia-prime in 14.04.
