Screenshot of the situation (yes I know I can't show that NO GUI is shown)

I use the Root analysis programme from the Science repo (installation was
"zypper install root6-devel" iirc). When I try to open any kind of GUI from the
interactive shell, I am given the information that I can't because I am in
batch mode.

Note that Root *can* be started with `root -b`, but that's not what I do. I
also know that on other platforms, Root can have issues with Wayland. That's
why I logged out of my "normal" Gnome Shell, and logged in as "Gnome on X11".
The behaviour is the same.

Steps to reproduce:
- Install root6
- log in (tried in Gnome/Wayland and Gnome/X11)
- Terminal: `root` with no arguments
- Start any GUI, for instance `new TBrowser`

Expected behaviour:
A GUI is launched.

Actual behaviour:
I get an error message reading

 Warning in <TBrowser::TBrowser>: The ROOT browser cannot run in batch mode 

No GUI is opened.
