I have set-up Synergy with an OSX server and a Ubuntu host. It's working nicely, except that the mouse wheel doesn't work in Linux. I used to xev command to verify that no input at all is registered when operating the mouse wheel.

I have found various bug reports about this problem, dating back from 2009, but no solution.

I also found a few blog posts where source-code patches can be downloaded. But when I tried to build the code I got errors about a missing i386 directory. (I fear that trying to build the project myself will lead to many hours of frustration..)

Does anyone know where I can download a OSX build with the applied patches?

I found the answer here

Fix for every installation so far -- I see mostly people using linux as the client so in this scenario I'm using Windows 7 as the server and fedora 12 as the client.

On the client:

tail -f /var/log/messages

now scroll as slow as possible and take note of the errors streaming in.

Example:

Feb  1 18:32:45 localhost Synergy+ 1.3.4:
2010-02-01T18:32:45 WARNING:
Wheel scroll delta (28) smaller than threshold (120)#012#011CXWindowsScreen.cpp,858

This is pretty self-explanatory. Take note of the delta. For this setup, when I scroll slow, I get 28.

So now run this on the client:

killall synergyc; sleep 1; synergyc --yscroll <lowest delta> <ip of server>

Literal example:

killall synergyc; sleep 1; synergyc --yscroll 28 10.0.0.1

Make sure to go through any session files or setting you created to include your new yscroll function.

And don't use 0 or 1 (unless your delta is 1). 0 created some odd issues. You want to set yscroll to your lowest possible literal delta. 0 or 1 neither accurate nor efficient.
