I don't think you need the dependency on FB either, since this file should only get included if CONFIG_FB is set? > + help > + This driver displays all kernel log messages on all connected > + framebuffers.

Do command line options exist to specify screens to write the debug log to? It might be a useful feature to have. ~Ryan -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
