The error is as follows: (!) DirectFB/FBDev: Could not set video mode (FBIOPUT_VSCREENINFO)! --> Bad file descriptor
This is not because of CreateWindow failing but because the FB driver doesn't seem support the resolution which is being requested for the window surface. You need to debug why this is so. Try a simpler application which creates some window surfaces instead of df_window. cheers, Amarinder On Wed, Jan 7, 2009 at 8:20 PM, Tom Cooksey <thomas.cook...@nokia.com>wrote: > Running the df_window example on my stb225 device fails in a strange way. > What's stange is that the mode seems to be set ok and the background is > painted fine.
