Bug 5571

I have a T42 with the Radeon 7500.
I can't even get dual head to work in 6.8.2. I have an external LCD connected on
DVI. Is your external monitor connected using VGA cable or DVI ?

Can you attach your xorg.conf for both version.

Also look at bug #3621. Some work is being done.

My monitor is attached by VGA.  Haven't tried w/ DVI 
This xorg.conf file has worked w/ XFree 4.2 & 4.3 and xorg 6.7 and 6.8.2.

LVDS + DVI is not yet supported by the radeon driver. If you want to use the vga
port, you may need to force the monitor types:
Option "MonitorLayout" "LVDS, CRT"

How far has you come with the LVDS + DVI support ?
Will it be there soon?
What can we do to help out?

I'm curious whether my xorg.conf file solved your dual-head problem for 6.8.2?

Nope, sorry.. But I guess its because of the DVI I am using!


Alex
I am running Ubuntu 5.10. Any easy way I can provide some data for you?
Can you provide the compiled driver libs or something to test? Or do I have to
compile it all?
I guess everything will become easier when we all switch to xorg 7.x !?

LVDS+TMDS doesn't work at all by default.  you can play with my patch (not
working 100%) or use the workaround detailed here:
http://ozlabs.org/~jk/docs/mergefb/

This is problably solved with current cvs xorg radeon driver. Please install and
test. 
If this fixes your issue, please close this bug.

Did my suggestion fix your issue?
