      And the transform parameter ? Doesn't have any effect ?

        Doesn't effect at all.. the Qt app ignores the frame buffer rotation completely...

          Might be a bug then... Did you check the "bug report system":http://bugreports.qt-project.org/issues/ to see if something similar has already been reported ?

              Another test I can think of is to build your QtEmbedded for x86 with the same options and qfvb additionally and try to start your program with the same command line options directing the output to qvfb

                Good idea, but I think the transposed is good enough for me now.. maybe i'll go back to that later on.
                Thanks alot! :)

                  You're welcome !

                  If you have everything working now, could you update the thread title prepending [solved] ? So other forum users may know a solution has been found :)

                      @SGaist said:

                      n try (maybe using ssh) to rotate the whole frame buffer after the application launch

                      Hi Is this issue been resolved ?
                      I also need rotation. Does Qt does the rotate in its library or does it expect the framebuffer dirver to do the rotation ? I ask becuase our Hw/fbdev driver does not support rotation, so I wander if rotation in Qt should work.
                      From this thread it seems that Qt can't do the rotation without HW/framebuffer support....

                      Thanks,
                      Ran
