Terrible response time when using Synergy on client side on Hardy

[Mayank Rungta]

Hi all,

I have used synergy to access multiple systems with a single master 
system. I am currently using two laptops:

Server: Gutsy
Client: Hardy

When I try to access the client through the mouse of the server the 
system response is pretty bad. The mouse freezes often. I was using 
quicksynergy from my account. I invoked the command

$  synergyc -f -1 --no-camp <server-ip>

explicitly from the terminal without much luck. But when I gave the same 
command as a root it worked like a charm.

I din't remember noticing any such problems with Feisty earlier so I 
reversed the laptops:

Server: Hardy
Client: Gutsy

The response is a little slow but not so terrible. Again with the 
superuser account this is better. On Hardy this is intolerable. I 
believe this is to do with the priorities of the processes. Is there a 
way to fix it so that I can get a good response for a normal user. 
synergc should count as a I/O intensive process but I am not sure why it 
works fine when process has been created by root and not otherwise.

Hardy is installed on a Thinkpad T61 while Gutsy is on a Sony VAIO 
VGN-240E both dual core with 64 bit versions of Ubuntu.

Thanks in advance,
Mayank
