glxconvenience: Add a QT_XCB_FORCE_SOFTWARE_OPENGL environment variable.
The QT_XCB_FORCE_SOFTWARE_OPENGL environment variable is equivalent to
LIBGL_ALWAYS_SOFTWARE for Qt 5 applications only. This is most useful
with drivers that only support OpenGL 1. We need OpenGL 2, but the user
probably doesn't want LIBGL_ALWAYS_SOFTWARE in OpenGL 1 apps.
Together with
http://pkgs.fedoraproject.org/cgit/qt5-qtbase.git/tree/10-qt5-check-opengl2.sh
which goes into /etc/X11/xinit/xinitrc.d, it makes QML 2 just work on
old hardware that supports only OpenGL 1.x in hardware. The scriptlet
checks the glxinfo output for the OpenGL version and sets
QT_XCB_FORCE_SOFTWARE_OPENGL if the major version is < 2. (The scriptlet
requires xorg-x11-xinit and glx-utils.)
Tested on a Radeon 9200 SE (RV280) that supports only OpenGL 1.3 in
hardware.
