Oops, sent the above without a comment. The second patch is against the
xserver-xorg-video-mga package. Patch in the src directory again. It
maps the framebuffers correctly and makes the mga driver work in
xinerama mode for me. As with the above, this works for me but use at
your own risk!

OK. I'm going to try to do a better patch than this which just changes
the MGA driver but for now you need two patches. Here is the first
against the libpciaccess library which disables the duplicate mapping
check. This isn't how it should be done, but it's a quick hack and it
does get the thing

Here is a better patch for the mga driver which doesn't require the
changes to libpciaccess. This one eliminates the duplicate mappings
and counts how many heads are using mapping to prevent unmapping too
early. It also fixes a bug I found where the i2c monitor detection on
the second head leave
I finally got the whole source package building/PPA thing working
properly. I've put an mga package in my ppa with the nicer fix in it.
It works without the libpciaccess patch and is running fine on my
machine.

Thanks for the feedback, that's a silly mistake in the patch. The
patched version of the driver ONLY works with a dual head setup, it
can't be used when there's only 1 screen or you get a NULL deref.
Should have thought of that really. Will do another one tomorrow (my
home PC doesn't have a matro
I wonder if the framebuffer for the second head is too small. By
default you only get 8Mb for it and you've a high resolution display.
Have you tried using
Option "Crtc2Half" "true"
in the device section for both heads? That should split the
framebuffer more evenly and might make the second he
Here's a new version of the patch that works with both 1 and 2 head
mode. The package in my PPA has been updated to have the newer version.

I see the same RANDR behaviour here, it works in single head mode but
not in multi-head. Doing 'xdpyinfo |grep RANDR' shows the extension
present in one case but not the other. I don't think this is anything
to do with my patch though, we have an Ubuntu 8.04 machine here that
behaves in exactly t
I upgraded to 9.04 recently and have also been using Bryce's patch with

I have the same issue with a G550 card in dual head mode and managed to
change the code to get it all working with some nasty hacks. It looks
like it was broken when they changed the driver to use libpciaccess to
map memory regions instead of using the old xf86MapPciMem calls. There
are two probl
Well I'd like to see this in Jaunty. What is it you need? Do you want
me to put Jaunty on a machine, install your package and check it?

Yes, I saw the mga_hal comment. The mga_hal is a binary only part of
the driver which gets loaded in to perform certain functions on certain
mga cards. I had a look but couldn't find the mga_hal binary on my
system at all, implying that it doesn't need this for dual head mode.
Presumably there's
Zaist: The mga_hal error you've got is generated if the driver decides
it needs the HAL using this macro:
#define MGA_DH_NEEDS_HAL(x) (((x)->Chipset == PCI_CHIP_MGAG400) && \
((x)->ChipRev < 0x80))
In other words for some revisions of the MGA 400 chip family you need
