I have been trying to get dual-head and tvout to work on an Dell Insprion 5100 with an ATI 7500 32MB under Fedora Core 3 to no avail this used to work fine on Fedora Core 1. Second display is always off that is the LCD screen, when crt connected any pointers please using default config done by system-config-display looks like a bug in radeon driver.

Could you please attach your xorg log? 6.8.x had some problems with display detection on certain radeons. you might try the patch from bug 1559 or try the latest xorg cvs. You should be able to work around the detection problem by using the monitorlayout option in your device section for screen 0, e.g.: Option "MonitorLayout" "LVDS, CRT" Also, at this time, TV out is not supported by the xorg radeon driver.
I have tried the Option "MonitorLayout" "LVDS, CRT" as you suggested and it works but only under level 3 and doing startx manually, under normal boot up it freezes as x windows initialises on Fedora Core 3, had to remove setting I am submitting my xorg log.

When will xorg radeon driver support TV out?
I am having the same problem. I will follow on with an attach of my xorg.conf, and 2 X-Logs - one with No 2nd CRT connected, the other one with.

I am having similar problems. I have a Radeon Mobility M6 with an external LCD-screen connected. The radeon driver was unable to detect the external screen so I added: Option "MonitorLayout" "LVDS, LVDS" to my config. Now the problem seems to be that X cannot find any valid modes for the monitor, even adding Modelines manually does not work, X seems to ignore them and leaves me with one monitor.
Sorry about my post. I thought that I had done my fair share of searching before posting this bug. Changing the MonitorLayout to "LVDS, TMDS" fixed my problem.
(In reply to comment #3) You might also try placing a single-screen config file in /etc/rhgb/xorg.conf. This tends to make the early graphical config more reliable. After the system proceeds as far as setting up desktop manager, X is restarted using the primary config file in the usual place. Another slightly more drastic option is to edit /etc/sysconfig/init and changed GRAPHICAL to =no. I was having my own issues with dual-head and system startup (although not the same as your specific problem) and both of these changes did resolve my problem, by deferring dual-head startup until the system was fully loaded. <https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=140435> if you're curious.
<mharris> ok, a bug report with "radeon" and "atitvout" ==> NOTOURBUG <mharris> atitvout == poke at radeon registers under running X server IIRC
