Re: Dual monitors

For the monitor that says "OUT OF RANGE", you need to edit /etc/X11/xorg.conf
See the line about vertical and horizontal scanning frequencies. You need to set those to the specs of your monitor.
or the simplest approach is (from memory, not at linux station currently)
to revert to some generic settings like 1024x768. This will disable 3d acceleration, so if you want it yo'd need to...
then follow onscreen instructions (be sure to researching vertical and horizontal freq ahead of time)
ANSWERS:
Grub shows on both monitors, because the video card is still in boot up mode. As soon as the video card is initalized at startup, the settings you choose take effect. My experiance with ATi cards are mixed. But generally xinerama is the easiest way to get dual monitors. The second montor appears like a disco floor untill its memory buffer is initalized, which is done by either the 3D ATI binary drivers or configure xinerama to occupy that monitor
