Loggout Command not set - LXPANEL

I am using debian with rox and jwm, but removed jwm panel, because not all menu come out when install an aplication, so the lightweight panel is lxpanel.

When clicked buuton logout on lxpanel menu. come out dialog "Logout Command not set". This is happening when using lxpanel standalone without lxde-core or lxde full just instaled lxpanel only, with other window manager.

To fix this thing, we must create file /home/your_user/.config/lxpanel/default , or simply open home folder and create /.config/lxpanel/default.
because this file create at home, we can create it without super user (root or sudo)

nano /.config/lxpanel/default

and  fill it with :

[Command]

Logout=lxde-logout

ctrl+o then ctrl+x

make sure you already istaled lxsession-logout. if you just change windows manager without remove lxde, this step is not necessary.

sudo apt install lxsession-logout

now logout icon on lxpanel should working properly
