Xorg.O.log (WW) message

[sawbona at gmx.net]

Hello:

I have this message in my Xorg.O.log:

[code]
[    34.298] (WW) Unresolved symbol: fbGetGCPrivateKey
[/code]

I'm running Devuan ASCII with two NVidia caards for three monitors and using proprietary 
drivers.

I have searched all over the web and have found a great deal on posts/instances in which 
this same error is cited (as an entry in a Xorg.0.log file) but have not been able to find out 
why it is there and if has some significance.

After all, it is labelled as a warning ie: (WW).

It is (apparently) innocuous as my NVidia cards are working properly (save for an artifacts 
issue reserved for another post).

I'd appreciate if someone could give me some insight on this.

Thanks in advance.
