Keyboard trackball erratic

I've removed advertising from most of this site and will eventually clean up the few pages where it remains.

While not terribly expensive to maintain, this does cost me something. If I don't get enough donations to cover that expense, I will be shutting the site down in early 2020.

I don't know if there was a final solution to this issue but I had a similar problem that vexed me for about a week... (yes, I'm probably a little slow on the uptake!).

Anyway, I moved a server into a rack cabinet that had a compaq KVM switch with one of those nifty keyboard/mouseball units to control all the hardware... Well, the mouse was all over the place and I tried every variation I could think of based on the information in the document on your web site... I knew I was in the right area but just couldn't work it out... The solution was this...

There is a parameter in /etc/conf/pack.d/kbmouse/space.c which reads as follows

/* Control kbmouse wheel capability init and test */
int kbm_wheeltst = 0;   /* 0=init+test, 1=no init,force off, 2=init+force
on */
This is the default setting (I believe).

Technically speaking the keyboard/mouseball doesn't have a "wheel".

I decided to play with this setting and changed to a value of 1 and relinked...

The little trackball in the keyboard now works like a champ!!

I could not find any reference to this setting in any documentation / web site / man page etc...
