Here's what I've got:
Tried so far:
- Kernel 2.6.11-1.27_FC3
- Fedora Core 3
- Xorg 6.8.2
- ATI Mobility Radeon IGP 340M
- Secondary monitor is a HYUNDAI ImageQuest L72D
- Pavilion ze4229 notebook
- I've tried to use the GUI interface to tweak parameters
- I've manually edited the Xorg.conf file tweaking a couple things
I cannot get this thing to span the desktop across two monitors. However, it does
display a cloned image on both monitors by just plugging it into the notebook, but of course I'm trying to improve my productivity by using multiple monitors instead of ALT+TAB
switching all the time.
Now for the diagnosis:
I found this in the Xorg logfile
(WW) RADEON(0): Failed to detect secondary monitor, MergedFB/Clone mode disabled
(a few seconds in time pass and millions of poor little electrons get churned up in circuit land)

(**) RADEON(0): Enabling AGP Fast Write
(II) RADEON(0): Depth moves disabled by default
