Erik, the reason you saw that behaviour is because xfce4-terminal runs a server. When you open a second or third terminal it communicates with the server to open the new window, so they are all one process. So when you ran what you thought was a new binary, the old server was still running.
Please test with "--disable-server" - I suspect this would fix the bug. Likely what is happening is the same xfce4-terminal server is being used on both X displays, and is trying to reuse a resource across them both in a way that is not valid. Probably a pixmap or something. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1243354 Title: Xfce4-terminal cannot run on more than one X screen at a time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-terminal/+bug/1243354/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
