Ok, I suspect I have found the issue. Seems this hardware only supports
OpenGL 1.4 compatibility profile. Qt's EGL code is asking for at least
version 2.0, and so getting no valid context back.
Could you please install "mesa-utils" package and run "glxinfo". On the
hardware I have access to, I see these lines in the output:
Preferred profile: compat (0x2)
Max core profile version: 0.0
Max compat profile version: 1.4
Max GLES1 profile version: 1.1
Max GLES[23] profile version: 2.0
I need to figure out why the X11 glx code is working, but the EGL code
is not. I also need to understand why at least OpenGL2.0 is desired by
Qt.
An option is to use GLES2 on this hardware, but as the GL/GLES switch is
made in Qt at compile time, that won't be straightforward either.
