I use Ubuntu for gaming. In competitive gaming every millisecond matters.

I know that many people who use Windows use something called Leatrix Latency Fix which is basically a script that modify TCPAckFrequency. This reduce the online gaming latency by increasing the frequency of TCP acknowledgements sent to the game server.

On Mac OS X you can get this effect by running sudo sysctl -w net.inet.tcp.delayed_ack=0.

I've heard that the Linux kernel have a very advanced IP stack and can use many different TCP congestion avoidance algorithm. I don't know if that has anything to do with TCP acknowledge frequency. I also heard that the Linux kernel auto-adjusts TCP/IP settings for optimal performance.

Is there anything I can do to reduce TCP/IP latency?

Is it possible to run different window managers on different screens?

Example, I want to run a tiling window manager (such as awesome) on one screen, and then I would like to run a stacking window manager (such as Compiz) on another screen.

Is there any way (such as a command or environmental variable) to determine what window manager is the one actively running in the current session?

What is the difference between gstreamer0.10-plugins-bad and gstreamer0.10-plugins-bad-multiverse?

• What codecs are supported by the "good" plugin set?
• What codecs are supported by the "bad" plugin set?
• What codecs are supported by the "ugly" plugin set?

I would like a list of codecs in each plugin set.
