nanogui: Thread: Nano-X without a mouse

I am getting to the point where my embedded system using nano-X needs to
operate even when mouse is not connected.
From what I can see, nano-X server does not start if the mouse is not
connected.

Any quick tips on how to prevent that before I waste too much time
looking for it?

Martin,

Did you compile the nano-X server yourself? If so, you 'd want to go into
the Configs directory, find the config you used and then put a 'Y' next to
the NOMOUSE option to prevent nano-X from caring about the mouse entirely.

Yes, I am compiling nano-X myself and using SERMOUSE=Y, and I still want to use that mouse except make it optional.
If the mouse is there I want to use it, and if not then don't.
The same goes for the keyboard, because I have a serial (RS232) pad that can emulate the keyboard and mouse operation as an input device.
 
It all works fine when all 3 are connected, but the requirement is that the RS232 pad can be used alone.
 
I will try to play with config settings but the mouse and keyboard still need to work when connected.

You'll need to hack the mouse and kbd drivers so they
return a file descriptor when the device is present, but
return -2 (rather than -1) when not.  The -2 return allows the
srvmain.c code to ignore the driver not present return.

That is what I was afraid of but expected.
I can modify the code but I just wanted to know if this is the only way and there is no easier way (some trick).
Thanks for the -2 hint.
I will report the outcome when I get it done.
