You can only launch one rootless X server; i don't know currently why such a limitation, but you can always launch other X server as root. -- Laurent Carlier http://www.archlinux.org

It works fine if I use Xwrapper.config to run X as root but without it I see only a grey window. I did look into the manual pages but I didn't see anything that looks like it would make things work.

It seems the problem only affects QT programs, after some googling I have found 2 workarounds[1], it seems either of the following environment variables needs to be set: QT_GRAPHICSSYSTEM=native QT_X11_NO_MITSHM=1 For now I'll use the first one as it seems to be less "bad". Hope this helps someone else. [1] https://forum.kde.org/viewtopic.php?f=225&t=121093 -- Mauro Santos
