I have upgraded my system from 15.10 to 16.04 and the container from 14.04 to 16.04.

I have used the default cuda/nvidia driver in both. cuda 7.5 and nvidia 361.42

When I start the container I get the lightdm DM. I cannot move the mouse or use the keyboard. 16.04 is missing the kbd and mouse modules. Any ideas how to fix that.

Thanks

The proprietary NVIDIA driver that comes with 16.04 seems to be problematic. I had problems with it, and I've seen at least one other question complaining of problems. This is what I did to solve my issue; it should work for you.

  1. Enter a TTY by pressing Ctrl+Alt+F1.
  2. Log in with your username and password.
  3. Run sudo apt-get purge nvidia-* and confirm any prompts.
  4. Run sudo apt-add repository ppa:graphics-drivers/ppa and then sudo apt-get update.
  5. Run sudo apt-get install nvidia-364.

This will install the latest driver from that repository/PPA. It is a newer version than the one that comes with Ubuntu (361.42 vs. 364.15) and seems to be a bit more stable. It's also open source, so that's a plus ;-).

If you have any problems, or are confused by these instructions, leave a comment.

  • I followed your direction. The display is now working, but I have no mouse or keyboard control. I think ubuntu 16.04 is missing the xorg-kdb module. Any suggestion. – user63726 Apr 23 '16 at 03:11
  • Try running `sudo apt-get purge xorg-* xserver-xorg || sudo apt-get install xorg xserver-xorg`. This might make it worse, so be careful. – TheWanderer Apr 23 '16 at 10:51
  • I have tried it. I do not have mouse or keyboard control. There is something else that is missing. the kbd and mouse packages are not available for ubuntu 16.04, Do I need to remove the evdev package. i.e xserver-xorg-input-evdev. If I do that what is the alternative for keyboard and mouse. – user63726 Apr 23 '16 at 16:16
  • @user63726 I don't know about that – TheWanderer Apr 23 '16 at 16:16
  • I was able to get the 16.04 lxc container to have graphics (with functioning mouse and keyboard) I am not able to get graphics with lxc 14.04.3 container. – user63726 May 02 '16 at 23:21

This could happen because xorg inputs in your container where configured using xserver-xorg-input-kbd, which is dropped in 16.04. In this case you could solve this by reconfiguring the inputs using evdev. You can find, more information in this answer.
