Hello,Trying to port Ubuntu Touch to the ASUS Transformer TF300T. The port does boot and I can log in via adb, but the display stays black. The reason is that qml-phone-shell segfaults trying to load EGL.

First make sure you have hybris and platform-api built and installed at the android side (see phablet-dev-bootstrap).
Second, try exporting GRAPHICS=NVIDIA before starting the shell, that might help as we know the nvidia drivers uses pthread a lot, which is not properly solved yet at hybris (there's a wip branch afaik, will try to get that public).
As I managed to get SSH login and apt-get to work via an adb tunnel, I am prepared to start serious debugging, but I would appreciate if someone could point me at the right place to start looking.
https://wiki.ubuntu.com/Touch/Core/UbuntuDebugAndroid might help you as well, if you want to give gdb a try :-)
