I have recently installed Linux Mint 14 on my laptop with Windows 7 64 bit on the server. I've used Synergy before with a windows 7 64 server and a windows 7 32 client and it worked perfectly. I'm pretty confident the problem isn't the server/client configuration.
My problem is that the mouse works perfectly on the server, but when switching over to the client side it starts lagging and moving in choppy movements. I've tried messing around with the server "relative mouse" config, with the mouse properties on both machines, I've searched and I've tried just about everything suggested on this site, nothing works. I'm pretty sure it isn't a network problem, it was working when my laptop had windows (same setup otherwise) and if I reverse the roles (Mint as server, Win as client) the mouse works perfectly on both.
It seems that there's no real answer to this issue but if anyone has any ideas it'd be appreciated. I'm pretty new to Linux so I might have overlooked some configuration somewhere.
