Assume you wish to use Jenkins to build your BlackBerry 10 applications on a headless Linux system.
In this case on attempt to install SDK via ./sdkinstall you could face with the following error:
Qde: Cannot open display: Qde: Cannot open display: Qde: An error has occurred. See the log file
This issue could be fixed by in 4 simple steps:
a) install xorg-x11-xauth package
b) uncomment line "#X11UseLocalhost yes" in /etc/ssh/sshd_config
c) reboot system to apply new package and settings
d) reconnect to system via ssh using -X option (enabled X11 forwarding).
