    DM6467 is not generally compatible with the generic Linux GUI software, as the DM6467 has limited video ports which can only really work in YCbCr space as opposed to the typical RGB that a Linux GUI application like X expects. This is somewhat manifested with DM6467 only using V4L2 capture and display, as it only processes video streams in YCbCr and not graphics in RGB. I have not seen any graphics application requiring fbdev or RGB running on a DM6467 that I can recall.

    so DM6467 doesnt support X window

    DM6467 does not have OSD hardware ( for putting graphics on top of video or by itself), hence as Bernie was suggesting there is no Frame Buffer (FBdev driver) but only V4L2 driver for video display.  As you can tell from the error log, the system is looking for a /dev/fb/x type device (frame buffer device) which is normally used to control graphics.  But there is no such device in DM6467 becuase there is no such hardware to control.  Therefore, you would either have to hack the software layer to use YCbCr 422 instead of the expected RGB format, in which case you can use the video window(s) to display graphics (no OSD window hardware), or you can get another part to implement an external OSD solution.

    Sorry but i dont know how to hack the software layer to use YCbCr 422 instead of the expected RGB format, or how can i get another part to implement an external OSD solution.

    Neither of these is a quick fix, my intention was just to point out the limitations and offer potential options... of course it is ultimately up to you to evaluate your resources and determine the best approach.  We do offer other parts which include hardware OSDs such as DM6446.
