* glxconvenience: Add a QT_XCB_FORCE_SOFTWARE_OPENGL environment variable.Kevin Kofler2014-02-071-0/+29
| | | | | | | | | | | | | | | | | | | | | 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. Change-Id: Ief80d283820d6336052b8f390a0030ba9b687492 Reviewed-by: Jørgen Lind <jorgen.lind@digia.com>

* Pass the surface format to qglx_surfaceFormatFromGLXFBConfigGiuseppe D'Angelo2013-02-232-16/+11
| | | | | | | | | Instead of creating a default-constructed format and filling its field in, pass a pointer to an instance. This way we won't lose the renderable type set on the surface, but just fill in the other parameters.

* XCB: Correctly report the created OpenGL context version and profileSean Harmer2012-09-261-0/+2
| | | | | | | | | | | | | | | This commit fixes the xcb qpa plugin such that it now correctly reports the version and profile of the created OpenGL context in the QOpenGLSurfaceFormat. To do this we have to create a temporary X window so that we can make our new context current. We also handle the buggy nVidia drivers which incorrectly report 0 for the GL_CONTEXT_PROFILE_MASK query. The reduced format is also copied back from qglx_findVisualInfo.

* Revert "Remove the LIBS from platformsupport"Samuel Rødal2012-03-201-0/+1
| | | | | | | | | | | | This reverts commit cd6e90c70ac13065257422088ffa01537ed9c685. Prevent symbol lookup error when requesting alpha visuals with GLX in the xcb plugin. This means other plugins will also link against -lXrender, but we need this workaround for now.

* QtPlatformSupport: A helper library for platform pluginsJørgen Lind2011-06-103-0/+288
QtPlatformSupport is a static library. Platform plugins are meant to link against this library to pull in dependencies such as fontengines and convenience functions for finding the right GL configs. The linker will only pull in the symbols used, so the size of the library doesn't really matter
