Comment 5 for bug 281546

You can fix this problem by a simple workaround.

1. Enable DEBUG2 on synergy

synergy -d DEBUG2 -f YOURSERVER

2. Press the key that is not autorepeating

Look for the debug line that says 'discard autorepeat"

Find the keycode for the key that is not autorepeating, in my case it was the down and left arrows

0x74 and 0x71 respectively

Convert these to decimal values

116 and 113

Then run

`xset r 116`
`xset r 113`

restart synergy ...

I have no idea how to make this change permenent to X
