Hello,
I'm trying to get a virtual desktop in a LXD container running on a
Kubuntu 16.04 host. I didn't find instructions on how to achive this.
However, based on the information that I found, I have a container with
the following device configuration:
wexi@wd:~$ lxc config show tbox
name: tbox
profiles:
- default
config:
volatile.base_image:
de051f59f701c709515de3face41e53e66f329d6d5d34cc5d4818aa23a3f3a7d
volatile.eth0.hwaddr: 00:16:3e:e5:11:7f
volatile.last_state.idmap:
'[{"Isuid":true,"Isgid":false,"Hostid":165536,"Nsid":0,"Maprange":65536},{"Isuid":false,"Isgid":true,"Hostid":165536,"Nsid":0,"Maprange":65536}]'
devices:

/dev/fb0:

/dev/nvidia-modeset:

/dev/tty8:
path: /dev/tty8
type: unix-char
root:
path: /
type: disk
ephemeral: false
After trying to install Kubuntu into the container by installing the
kubuntu-desktop metapackage. However, sddm in the container fails to
start. I'm getting the following in syslog:
Oct 14 15:39:25 tbox sddm-helper[4078]: Received a wrong opcode instead

Oct 14 15:39:26 tbox systemd[1]: gpu-manager.service: Start request

Any ideas on what needs to be done to get sddm/X running in the container?
