Start synergy on boot in Ubuntu?

For newer version of Ubuntu that use lightdm.

I have successfully done the following for running the synergy client for the login screen, andafter I login. It is much simpler than the other answers, IMHO.

edit /etc/lightdm/lightdm.conf as root.

sudo vi /etc/lightdm/lightdm.conf

add the following line to the bottom of the file.

greeter-setup-script=/usr/bin/synergyc 

restart lightdm. (it is better to do this from a terminal or ssh session)

sudo /etc/init.d/lightdm restart

it works good in 12.10 for me

Ubuntu User Permission

There are two ways to do this: set the directory to "world" writable or create a new group for the two users and make the directory writeable to that group.

Obviously making it world writeable is a Bad Thing, so the second option is preferable.

Users in Linux can belong to more than one group. In this case you want to create a brand new group, let's call it tomandruser:

sudo groupadd tomandruser

Now that the group exists, add the two users to it:

sudo usermod -a -G install user1
sudo usermod -a -G install user2

Now all that's left is to set the permissions on the directory:

sudo chgrp -R tomandruser /path/to/the/directory
sudo chmod -R 770 /path/to/the/directory

Now only members of the tomandruser group can read, write, or execute anything within the directory. Note the -R argument to the chmod and chgrp commands: this tells them to recurse into every sub directory of the target directory and modify every file and directory it finds.

You may also want to change 770 to something like 774 if you want others to be able to read the files,775 if you want others to read and execute the files, etc. Group assignment changes won't take effect until the users log out and back in.

sudo apt-get install curl libcurl3 libcurl3-dev php5-curl

After installing libcurl you should restart the web server with following command,

sudo /etc/init.d/apache2 restart
