unetbootin: cannot connect to X server

I'm trying to run unetbootin as root in the terminal. I am running Fedora 29 in Gnome. I'm not new to linux but I've been away from computers for 5 years so my skills are... diminished.

[root@localhost ~]# unetbootin
unetbootin: cannot connect to X server

Help?

Googling for the specific error message within quotes ("unetbootin: cannot connect to X server") returns the following:

https://github.com/unetbootin/unetbootin/issues/94

suggesting a workaround for running unetbootin under Wayland.

Does that help?

techtonik's workaround

Quote:

On Fedora 25 the magic workaround:

1. under user run

```
$ xhost local:root
non-network local connections being added to access control list
```

1. then with `sudo`

```
$ sudo QT_X11_NO_MITSHM=1 /usr/bin/unetbootin
```

I can not explain why it is necessary. =/

Well that workaround gets unetbootin to open but then it fails when i tried to burn an .img to the usb drive

libpng warning: iCCP: known incorrect sRGB profile

shows in the terminal

suggestions?

Any use?

No I still can't get it to work. Very frustrating. I've had no issues with unetbootin in the past. It worked fine until I installed Fedora 29.
