FB_FIND_MODE(9) 		       Frame Buffer Library			  FB_FIND_MODE(9)

       fb_find_mode - finds a valid video mode

       int fb_find_mode(struct fb_var_screeninfo * var, struct fb_info * info,
			const char * mode_option, const struct fb_videomode * db,
			unsigned int dbsize, const struct fb_videomode * default_mode,
			unsigned int default_bpp);

	   frame buffer user defined part of display

	   frame buffer info structure

	   string video mode to find

	   video mode database

	   size of db

	   default video mode to fall back to

	   default color depth in bits per pixel

       Finds a suitable video mode, starting with the specified mode in mode_option with fallback
       to default_mode. If default_mode fails, all modes in the video mode database will be

       Valid mode specifiers for mode_option:

       <xres>x<yres>[M][R][-<bpp>][@<refresh>][i][m] or <name>[-<bpp>][@<refresh>]

       with <xres>, <yres>, <bpp> and <refresh> decimal numbers and <name> a string.

       If 'M' is present after yres (and before refresh/bpp if present), the function will
       compute the timings using VESA(tm) Coordinated Video Timings (CVT). If 'R' is present
       after 'M', will compute with reduced blanking (for flatpanels). If 'i' is present, compute
       interlaced mode. If 'm' is present, add margins equal to 1.8% of xres rounded down to 8
       pixels, and 1.8% of yres. The char 'i' and 'm' must be after 'M' and 'R'. Example:

       1024x768MR-860m - Reduced blank with margins at 60Hz.

       The passed struct var is _not_ cleared! This allows you to supply values for e.g. the
       grayscale and accel_flags fields.

       Returns zero for failure, 1 if using specified mode_option, 2 if using specified
       mode_option with an ignored refresh rate, 3 if default mode is used, 4 if fall back to any
       valid mode.
