[lxc-users] nvidia graphics support in lxc (2.0, ubuntu 16.04)

[Oz Dror]

I have tried your suggestion about downgrading the mesa utils on the
server. I still cannot get any video if the lxc is 14.04.
If the lxc is 16.04. I do not get mouse and keyboard. Downgrading glx makes
no difference. Any ideas how I can get video in 14.04 or mouse/keyboard on
16.04.

Thanks
