DRY – Don’t repeat yourself
KISS – Keep it simple, stupid
YAGNI – You ain’t gonna need it
PEBKAC – Problem Exist Between Keyboard And Chair
SoC – Separation of concerns
Issues generally come in three forms:
Citrix Receiver download.
Here is the offical how to guide.
The following command can be used to test for window manager support.
If there is no output, there is no support.
xprop -root | grep _NET_WM_FULLSCREEN_MONITORS
Further troubleshooting infos here.
In my case, I just had to launch the configuration manager and set it to “Full Screen”.

Open LXC config file in your favorite editor. In this case the container name is 101:
nano /etc/pve/lxc/101.conf
Append a single line for each mountpoint you want to add. The first mountpoint is “mp0”, the second “mp1” and so on.
mp0: /data/music,mp=/mnt/nfs/music
First the source (my zpool “data”, folowing the dataset name “music”), after that the destination inside the container beginning “mp=”.
