Hi Mike, I assume you are using the FB driver fbdev. If you can use fbset to verify the resolution, I can only guess what can be the problem. The error message suggests you have not enough memory, so you can try: - use 'frontonly' as buffering mode, so the framebuffer will only have 1 single copy of the screen. You have to put "layer-buffer-mode=frontonly" or "desktop-buffer-mode=frontonly" in your directfbrc, depending on your config. - or try a smaller resolution, to see how big still works
You also want to use ARGB1555, but I see "rgba 5/10,5/5,5/0,1/15" in your modeline, that's already ok, I suppose? There are 3 ways to be sure. - use SetConfiguration on the display layer (so you need to do GetDisplayLayer). The layer must be in exclusive access, so you will also have to do SetCooperativeLevel on the display layer. - you can put it in your configuration file directfbrc. Use "pixelformat=...." or "layer-format=..." depending on your configuration. - if you are using windows, you can also set the pixelformat in "CreateWindow". Then, directfb will switch to this format if this window is displayed (if you show multiple different format windows, directfb will do a 'best-effort' which is normally fall-back to the directfbrc content).
