Proprietary graphics not available to Snappy packages

[Michael Hall]

The proprietary nvidia drivers are not accessible from snap packages, they need to have a bind mount made to a location where snaps can use them. Please see the conversation below for more details:

10:24 < mvo> mhall119, mattiasw: I looked at the nvidia issue and it works here now, there are two issue: a) we do not auto-bind-mount the right nvidia directory, this needs to get fixed in our nvidia drive pkg, as a workaround we can sudo mount -o bind /usr/lib/nvidia-361 /var/lib/snapd/lib/gl/ b) the bin/qt5-launch script overrides our LD_LIBRARY_PATH, trivial fix is to just ensure that before the actual launch of krita "$SNAP_LIBRARY_PATH:$LD_LIBRARY_PATH" is set, this ensures that the right gl library (the nvidia one) wins over mesa. if there is a git repo or anything like this I can provide a patch for bin/qt5-launch

10:24 < mvo> mhall119: do you think you could chase our nvidia packagers to include a systemd bind mount unit from "sudo mount -o bind /usr/lib/nvidia-361 /var/lib/snapd/lib/gl/" ?

10:31 < mhall119> mvo: I assume the nvidia package fix needs to be SRU'd into 16.04's archives, it's not something that gets fixed in ubuntu-core images

10:32 < mvo> mhall119: yeah, we need to get this SRUed

10:32 < mvo> mhall119: not something we can fix in the image
