      I hate to drag up an old post, but my question is exactly the same. I've searched all over but I can only find QWSServer::setBackground. How do you set the color of the framebuffer without QWS?

              LinuxFB, we have no hardware acceleration.

                  AFAIK, there's no equivalent for the LinuxFB plugin. Out of curiosity which background are you thinking about ? The one from your widget or while your application is loading ?

                      For example, if I have a QDialog in windowed mode and move it, what color will it be when it redraws the empty space? With QWS you could select that color.

                          From my understanding of "this":http://qt-project.org/doc/qt-5/embedded-linux.html is that you won't have that option at hand

                              There is no equivalent. You can create a fullscreen widget that just fills itself with the desired color.
