How do I use xhost for this situation?
I am currently trying to make an autonomous drone using the Robot Operating System (ROS). To do this, I have installed Raspbian Lite (Jessie) on a Rasperry Pi 3 and am currently using ROS Kinetic on it. I decided to go with Openbox Window Manager and installed a terminal onto it for convenience. I can just call sudo startx. Since it is a system-wide terminal, I have also installed tmux for convenience. I am running the xserver on a particular pane and conduct my ROS work on other panes.
Now when I try to run commands that call on a GUI application from my system-wide terminal, I get the error:
QxcbConnection: Could not connect to display
Aborted
After a recommendation from this question, I decided to install xhost on my terminal emulator. After invoking xhost + in the same emulator, I get this:
access control disabled, clients can connect from any host
After which I invoke xhost which returns with:
access control disabled, clients can connect from any host
SI:localuser:root
Therefore, within my system-wide terminal, I have set the environmental variable to 5 different values which have been listed below, and tried to run the program which calls on the $DISPLAY, but I get the same QxcbConnection: Could not connect to display error.
SI:localuser:root
localuser:root
localuser
root
SI:localuser
localhost:0
The last one was actually from the linked question. To my understanding, I am doing exactly what is listed out in this man page. What am I doing wrong?
Extra notes
Currently my remote drone isn't flying at all. I am programming on the Raspberry Pi completely as of now. So therefore, the only way, that I can get a GUI screen is to output the GUI of the window manager from a kernel virtual terminal device. I want to know how I can connect from one virtual device to the other using xhost. Should I do this over the internet?
