Can't run xeroxofficeprtmgr as root on Linux

[fabienhespul · Accepted solution]

I figured out that this is caused by xwayland (for OS running with Wayland) not allowing to run software as root. Need to run the folowing command as documented in the archlinux wiki: https://wiki.archlinux.org/title/Running_GUI_applications_as_root#Using_xhost

xhost si:localuser:root

Now I can use the GUI of `xeroxofficeprtmgr` app.

[prtsys]$ sudo ./xeroxofficeprtmgr
[prtsys]$ cat /tmp/XeroxOfficeprtmgr.log

Can't figure out what to do with this fatal error. Any idea ?

I've installed x86_64 version of the driver.

Running the same binary without being root launch the "fax" app

Maybe it is related : The graphical interface is running under Wayland
