--- Comment #5 from Kevin Kofler <kevin.kof...@chello.at> ---
Oh, and:
* Doing this check in /etc/xdg/plasma-workspace/env/ is not that great a
solution, because QML can also be used in other desktop environments. For the
same reason, I also think Plasma is not the right place to ship this script.
Fedora installs the script to /etc/X11/xinit/xinitrc.d/10-qt5-check-opengl2.sh
in its Qt packaging.
* As for drivers that do not support LIBGL_ALWAYS_SOFTWARE, well, if those do
not support OpenGL 2 in hardware, there's not much I can do for you. QML 2
renders using OpenGL, so to get software rendering, you need an OpenGL
implementation that does software rendering. You would actually need some hack
like Bumblebee to run Qt with a different libGL in such a situation. That said,
haven't the proprietary AMD/ATI and NVidia drivers dropped support for ancient
OpenGL-1-only cards long ago? I think the Mesa ones are the only ones that
support such old hardware to begin with, and the Mesa libGL honors
LIBGL_ALWAYS_SOFTWARE.
