ROOT

Please provide the following information:

ROOT Version (e.g. 6.12/02): 6.13/01
Platform, compiler (e.g. CentOS 7.3, gcc6.2): gcc version 5.4.1

Hello, i have issues when i start root with the command ‘root’. When i have typed root in the
terminal, i get the message PopupLogo, XOpenDisplay failed. TBrowser dosen’t work either.
The weird part is that it worked yesterday, both root and TBrowser. Im using Ubuntu shell 16.04.4, xenial. Installed on windows 10.

Looks like you have a problem with X server, not root.
Do you have X server running?
Do you have the DISPLAY environment variable properly set in the WSL?

3

If i type $DISPLAY in the terminal i get:
localhost:0.0: command not found.
I have used this command in the terminal: export DISPLAY=localhost:0.0
And i get the same error

Does xterm work in the WSL?

If i type xterm in the terminal i get :

So, as I’ve said, the problem is in your X server, not in root.

I typed these commands in the console:
sudo apt update
sudo apt install fluxbox xinit xterm
and then startx
I got the following

X server does not run inside WSL (“bash shell” in Windows®™ 10®™).
If root worked yesterday, it means you have X server on Windows®™. Something like Xming.
Make sure it is running or restart it.

I forgot that i have not Xming started yet, that fixed the problem.
Thanks for the help
