I actually did use this(xinerama), but found it extremely annoying since alot of applications and browsers etc either opened in the middle of the 2 screens(half on each screen) or would open from the one screen and STRETCH across most or all of both screens. I like to have them set up seperately as linux almosts works as if each screen is a different user. I have seperate taskbars(panels) and can set up each monitor exactly as I wish. One drawback to using the monitors seperately, if you open a program on one monitor, it does not look as though you can drag it onto the other monitor (it wraps around and comes back out on the same monitor, other side) whereas I could move apps between monitors in the other mode. On a side note, does anyone use the Konqueror web browser? It is really sweet, but seems to crash all the time. I was wondering if the crashing was it or me.. hehehe, it seems to crash alot more often on the radeon screen than on the sis screen. Hmmm... anyhow... I am off to find that config file!
