Booted notebook. While in GUI added external monitor. Image displays on both.
Pressing Fn + CRT/LCD switch has no effect.
Switched to a text console, CRT/LCD switching works there. Back to X, image
displays again on both monitors.
This is a DELL Latitude D600 with Fedora Core 4.
I haven't tried rebooting/restarting X with external monitor added.
Initially reported to redhat at
what sort of graphics chip does your computer have? If you have a radeon, you
can use the "bioshotkeys" option to enable hotkey switching, however this option
is only available in cvs. If you have a radeon is a duplicate of bug 2000.
It's Radeon, thank you Alex
