smallest size

[nbctcp]

Hi,
This is not an issue but I want guidance
Currently I remove chrome from Dockerfile because Chrome always snap error
The image size become 540MB
QUESTIONS:

1. if I want smallest possible. what else should I delete
2. which one faster between vnc vs rdp
   how to enable only either one
3. I got error when connecting using vnc
   "Another user already login with this id"
   if I switch to rdp, I need to click OK on Session XVNC
   then I have to click menu Firefox to launch it
   Is that possible to autologin then autostart firefox
   tq
