    7474name of the video mode to use video mode (must be listed in 
    7575/etc/fb.modes).  Default is not to change the video mode. 
     76In the past, the XF86 config file (/etc/X11/XF86Config) used to contain Modeline  
     77information, which could be fed to the modeline2fb perl script (distributed with fbset). 
     78On many modern xorg based systems, there is no direct way to obtain a fb.modes file from the xorg.conf file. 
     79So instead one could obtain useful fb.modes info by using the (fbmodes (no man page AFAIK)) tool, written by bisqwit. 
     80An unsupported mode should make fim exit with failure. 
     81But it is possible the kernel could trick fim and set a supported mode automatically, thus 
     82ignoring the user set mode.
