Just installed Slackware 14 and using KDE both monitors work great. I can stretch the desktop across both monitors. However, if I startx using XFCE I can't seem to figure out how to configure the dual monitor setup. By default both monitors are mirrored. I need help figuring out how to configure a dual monitor setup with XFCE so that the desktop is stretched across both screens just like KDE.

This question came from our site for professional and enthusiast programmers.
xrandr is always a mighty alternative if your window manager does not offer the right options for multiple monitors.
Check the output of "xrandr" to see the available monitors and resolutions.
Check "xrandr --help", especially for the option --right-of.
