gtburst not working

[Liaomao123]

Hello everyone, when I installed fermitools, it showed that the installation was successful, but when I used Gtburst, the following error occurred!

(fermi3ML) lm@LAPTOP-PGKLAI6C:~$ gtburst

GUIs like gtburst use X-Windows (aka X11) system that is common on Unix and Linux. The "no $DISPLAY environment variable" indicates that gtburst can't communicate with X windows system. Since you are using the Windows Subsystem for Linux, I'm guessing something didn't get setup correctly. The FSSC doesn't have much experience with WSL support (since we mostly use Linux and MacOS machines), so it's difficult to say how to fix it. It might be as simple as setting "export DISPLAY=:0", but you will probably need to google something like "WSL and X-Windows" or "WLS and display variable". Maybe something on this page might help: https://askubuntu.com/questions/1299323/how-to-set-up-display-variable-for-wsl2-of-ubuntu-20

It's strange, when I set export DISPLAY=:0, it still doesn't work.

@Liaomao123 Windows 10 is not working yet, you can try to upgrade your system to windows11 professional edition, all my current GUI tools can be used in windows11 system.
