BinaryDriverHowtoATI for Karmic Koala

[Patrick Doyle]

Can somebody point me at a resource for the BinaryDriverHowtoATI (see
https://help.ubuntu.com/community/BinaryDriverHowto/ATI) updated for
Karmic Koala?

Specifically, as I read through that page, I see instructions that say
to do things like:

$ sudo dpkg-reconfigure -phigh linux-restricted-modules-`uname -r`
$ sudo insmod /lib/modules/`uname -r`/volatile/fglrx.ko

Being a curious sort, I started wondering what that might do (before I
tried it), so I tried:

$ sudo debconf-show linux-restricted-modules-`uname -r`

which produced no output.

So I tried:

$ apt-cache show linux-restricted-modules-`uname -r`

which indicated that there was no linux-restricted-modules package.

That's fine.  That's probably something that has changed between 9.04
and 9.10.  But I'm not really sure what, if anything, I should do in
its place.

Then, later on the howto, I read:

JAUNTY NOTICE

      The above Jaunty 9.04 instructions don't actually work because
the latest ATI driver is incompatible with XOrg 1.6. To see a guide on
instructing how to downgrade XOrg and install the ATI driver, view
this link: ...

...which makes me wonder if the latest ATI driver might be compatible
with whatever version of XOrg is shipped with 9.10.

...which makes me wonder what version of XOrg is shipped with 9.10.  I
could probably look that up in the release notes, but instead I tried:

$ apt-cache show xorg

...which lists a version as:

Version: 1:7.4+3ubuntu7

Since I've run into this issue before (of not knowing how to a
software package version number), I figured I'd ask the question
now...

How can I tell what version of XOrg is shipped with Karmic Koala?  It
looks like it could be 1.7, or perhaps it could be 7.4.  Regardless,
it seems to be one that doesn't require xorg.conf.

...which brings me to my next question...

How can I see the "effective" xorg.conf in use by my server?

Oops, I digressed....

I _do_ have one more question regarding the ATI driver for Karmic Koala...

How can I learn what is done (on my behalf, and behind my back) when I
open up the System > Hardware Drivers ane Activate the ATI/AMD
proprietary FGLRX graphics driver?

I suspect that the GUI installs xorg-driver-fglrx, but I don't know
that for a fact.  Nor do I know what else might be done... and I'm
curious.

Thanks for any tips and help you can give me.  (Especially tips on
where I could have learned this information myself... I'd rather go
fishing than eat the fish you can give me.)
