           Summary: [NV4B] Composite broken on 2nd head
           Product: xorg

Xorg log

When using metacity's composite manager, windows moved from my primary head
(LVDS) to the second head (DVI-D-0) do not appear at all.  The mouse pointer
appears correctly, and the pointer changes depending on the contents of the
invisible window as normal (ie: a text-caret when over a textbox, etc).

This happened with the switch to metacity 2.21.8.  One of the changes to the
compositor was to use the Composite Overlay Window.  The kwin's compositor in
KDE4 also exhibits the same behaviour.

Composite works correctly when using xcompmgr, which leads me to suspect that
it's a problem with the COW on the second head.

Did X have a left+right config at startup or was this changed with xrandr (or
some other config app)? I may have a suspicion what the problem is, but i need
to gather some more info.

This was changed with the command "xrandr --output DVI-D-0 --right-of LVDS-0". 
If you'd like me to check with this set up in xorg.conf, I'll need to find out
how to do it :).

Right, good guess.

When the dual head setup is specified in xorg.conf, everything works fine. 
Playing around with xrandr in this case, I see:
Switching from right-of => same as => right of: correct behaviour.
Switching from right-of => left-of: correct behaviour.
Switching from right-of => above: buggy behaviour: the screens are correct up
to the original maximum vertical resolution, and broken below it.

It seems the COW is not resized with xrandr changes.

I have some issues with my system that prevent me from fixing this on the very
short term, but i will have a look at this later.

This is a (test) patch against xserver git, so it may not apply perfectly
against against 1.4.x, It's also untested as i have no test application for the
moment.

I've just applied your patch to Ubuntu's X server (which seems to be a git
snapshot as of 2008/01/31), and it fixes this.  Sorry for the delay.

Yes; I was running the same git snapshot, but minus the patch.  The Ubuntu X
packages are merged from Debian experimental I believe, if you're more familiar
with them.

I haven't tried with a raw build from freedesktop git.  The Ubuntu packages
have a bunch of extra patches applied to them, which may affect things?

Maybe i'm just not hitting the situation, i don't have a full gnome desktop
installed, only metacity. I'll have to poke some of the xorg guys about a few
things before i can call that patch finished.

Confirmed, applied to Ubuntu's packages with a git snapshot as of 2008/01/31. 
Everything works fine with the above patch, xrandr resizing breaks Metacity's
compositor (as described previously) without the patch.
