问题
I am trying to run the hellogl_es2 Qt example without X Server by specifying the eglfs platform:
./hellogl_es2 -platform eglfs
EGL Error : Could not create the egl surface: error = 0x300b
Aborted (core dumped)

Distribution is Ubuntu 14.04.4 LTS (trusty).
Qt version is 5.2.1, installed from http://packages.ubuntu.com, armhf architecture, packages qtbase5-dev, qtbase5-examples, qtbase5-examples-dbg.

The behavior is the same with other Qt example projects.
I tried to remake Qt from sources with or without applying this patch: https://patchwork.openembedded.org/patch/66349/ but with no result (same error).

I had This problem With qt 5.2 on Cubieboard A10 and fixed it by compiling from source and changing qeglfshooks_stub.cpp according to this tutorial Qt On Cubieboard
Hope This helps
