You're between a rock and a hard place? ;-)
BTW, could you try to configure your e-mail program to use proper quote mar=
ks (=E2=80=9C>=E2=80=9D)?
It's kind of hard to find what you wrote without it.

Setting "AutoAddDevices" to "off" is probably sufficient. And you only
need to rebuild xorg-server AFAIK.

Ok. Weird. But that could also be a bug in xscreensaver.
Check if it is possible to disable one of the graphics chips in the BIOS.
That could be a last resort fix. AFAIK Xorg doen not have proper support for
using two graphics cards or switching beteen them.

In the device section for the chips, you can specify it which monitor secti=
on
to use. See xorg.conf(5) excerpt below. N.B: the output for the built in pa=
nel
is probably called =E2=80=9CLVDS=E2=80=9D.
MONITOR SECTION
The config file may have multiple Monitor sections. There should n=
or-
mally be at least one, for the monitor being used, but a default c=
on-
figuration will be created when one isn't specified.
Monitor sections have the following format:
Section "Monitor"
Identifier "name"
entries
...
EndSection
The only mandatory entry in a Monitor section is the Identifier ent=
ry.
The Identifier entry specifies the unique name for this monitor. =
The
Monitor section may be used to provide information about the specifi=
ca-
tions of the monitor, monitor-specific Options, and information ab=
out
the video modes to use with the monitor.
With RandR 1.2-enabled drivers, monitor sections may be tied to s=
pe-
cific outputs of the video card. Using the name of the output defi=
ned
by the video driver plus the identifier of a monitor section, one as=
so-
ciates a monitor section with an output by adding an option to =
the
Device section in the following format:
Option "Monitor-outputname" "monitorsection"
(for example, Option "Monitor-VGA" "VGA monitor" for a VGA output)
In the absence of specific association of monitor sections to outpu=
ts,
if a monitor section is present the server will associate it with =
an
output to preserve compatibility for previous single-head configu=
ra-
tions.
But I guess you'll have to remove one of the cards from your xorg.conf.
to force Xorg to use the other one.
> Also, how does no hal work? What does that effect with regards other app=
s?
No HAL means you have to tell Xorg more about the hardware. But otherwise it
works fine. I'm not sure what other stuff uses hal. I have never used it no=
r missed it.
But I'm using only a light-weight tiling window manager instead of a full f=
ledged
desktop environment.
> Are you speaking of using the devd option in make config too?
Nope. That's just for input devices. I'm not using that either.

You need vt(4) to do a graphical boot, and to get an utf-8 capable console.

You might want to try and disable the HD6300 and then run kldstat again, to
see which radeon* modules are specific to the HD4200. Because those are the
ones you need to load /boot/loader.conf to get vt(4) working on 10-STABLE.

Hope this helps.
