i have reported this bug to FC9.

This issue is reproducible when using the latest driver from git repo.

When dual head is enabled with randr12 option, primary display is borked, and
secondary display is borked if dvi connector is used.

Hi, still interested in fixing this? If so:
* can you check the problem is still present on the latest version in git?
* am I correct to understand that when RandR12 is enabled, the laptop display
is incorrect, even without having the external DVI screen plugged in? Also, by
running with `Option "Randr12" "off"' in xorg.conf and starting from a fresh
boot, the problem is not present?
* assuming the problem can be reproduced using only the laptop screen, is the
display still broken on returning to VT (either by Ctrl+Alt+F(n) or by closing
X)?

Yes. If i restart X after disabling RandR12, i end with with a "telly" like
screen ( horizontal rolling strips )

Assuming it doesn't work with updated software, can you also try:

1) starting from a non-corrupted state, start nouveau with
nv_bios.c:call_lvds_script patched out:

--- a/src/nv_bios.c
+++ b/src/nv_bios.c
@@ -2965,6 +2965,7 @@ void call_lvds_script(ScrnInfoPtr pScrn, struct dcb_entry
*dcbent, int head, enu
        uint32_t sel_clk_binding;
        static int last_invoc = 0;

+       return;
        if (last_invoc == (script << 1 | head) || !lvds_ver)
                return;

and check whether the picture in X is ok, and whether the picture on returning
to console is ok.

2) Make register dumps while in X, and attach them here -- one with randr12
disabled (and no corruption present), and one with randr12 enabled and the
corruption present -- as follows:

git clone git://people.freedesktop.org/~stuart/radeontool
make
./radeontool regs > logfile

Nope. All i see is blank black screen. Switching to console and back to X, i
end up with a image of console ( translucent) on X. 

The console works fine.

Hmm, a blank screen is surprising :-) As regards this translucent console, I
don't understand -- how is it different to the normal console display? what
indication is there that you are in X and not still at the console?

> The console works fine.

I assume by this you mean that the console is fine after leaving X; correct me
if I misunderstood.

> > 2) Make register dumps while in X, and attach them here -- one with randr12
> attached.

There seems to be a problem here -- all four of the nouveau dumps appear to be
made from the console, rather than from within X. If you were doing them blind,
is it possible that X had crashed? If you were doing them from the console
while X was running in order to see, could you instead leave the computer *in
X* and run the dump commands from another computer over ssh?

Please close this bug, as I do not have access to the hardware in question.
