xorg.conf for Mac G4 mini
Hello, all!

I'm having the damnedest time getting X to run on my Mac Mini 1.25Ghz
(Radeon 9200 processor). I've wasted a lot of time following various
web instructions, but to no avail. One issue, of course, is the right
xorg.conf file. Another one may be (in some people's opinion is)
arguments to the Linux kernel/yaboot.

I see on this list that there has been some discussion on this
subject. However, the configuration files that apparently were once
posted on web sites are no longer available.

I wonder if anyone who has done this would be willing to part with the
sacred mysteries.

At one time, with kernel 2.22, I used Xorgautoconfig and it was good. A
recent attempt to get to a newer kernel and xorg has shown me that I
know nothing.
Re: xorg.conf for Mac G4 mini [ In reply to ]
This is too bad. Gentoo is the logical choice for old hardware, since
the source
code compilation allows the users to keep up with the latest releases
and bug
fixes, even though the distribution may not be under active development.

Your xorg conf problem has little to do with Gentoo. It is an xorg conf issue.
*Manual xorg configuration is not necessarily easy* on any distro, unless it "just works".
I would not use the kernel boot options initially (although that may be required, it
usually isn't).

Choosing Gentoo means you feel confident with manual configuration, or that you
are incredibly persistent and resourceful. The odds of google having your answer are extremely high.
Ubuntu forums are an excellent place to look. The odds of mini not working are close to 0.
This is actually not a very good place to ask, the traffic is extremely low - fortunately xorg conf
is not arch or distro specific so that should broaden your search horizon.

You will need the correct driver for your card 1st. Likely it will not be something
you compile into the kernel, but added with emerge. Nvidia drivers for instance, should not
be compiled into kernel on many cards.

You will also need to be able to look at and report the contents of your xorg error log.
That is your guide. (look in /var/log )
Also check on the xorg site for information, since it's really an "xorg" thing, more than a "Gentoo" thing.
Patience is your friend. First time around the block w manual xorg.conf can be difficult and frustrating. 2nd time too.

Perhaps this helps

To begin with, as directed in the Gentoo PPC FAQ, make sure that you've
set the correct framebuffer device. You can check which one you have set
by running Xorgautoconfig --dump. If you could paste that info into a
message, that would be helpful too. What exactly is the problem that
you're having? Most machines actually configure themselves automatically
now without an xorg.conf file.

Haha, I can tell it's been a while since I've helped people with X
issues. :) The application you should be using for X issues is "xac"
now, which replaced Xorgautoconfig. I wrote both of them, you'd think
I'd be able to keep it straight...

Re: xorg.conf for Mac G4 mini [ In reply to ]
Hello, Joe and JR:

Thank to both of you for your help; it took me until now to find the
time to once again find time to
fiddle with this problem.

The symptom is that the monitor gives a message that there's no signal
and goes away. Terminating X
with some combination :-) of shift keys and the delete key brings back
a text terminal. A very lengthy log
file gets generated, but to the best of my ability I can not find any
indication of an error in it.

Checked the FAQ, but I'm not clear how to "set the correct framebuffer
device" -- or what that might mean.

Probably my blindness, if you can direct me I'll be grateful.

JR, Thanks for the link and advice, but it didn't get me any further.
I used to do this configuration quite a bit, but in recent years it
hasn't been necessary.

Okay, this looks good. You are using the correct framebuffer driver (the
ATI Radeon driver and not the OpenFirmware FB driver, which won't work
for X) and it appears that your monitor is correctly responding with an
EDID for autodetection. Can you try generating an X config file with xac
and give that a try? If it doesn't work out of the box, try uncommenting
the "UseFBDev" option and try both "true" and "false", sometimes the
correct value is not autodetected by X.

Re: xorg.conf for Mac G4 mini [ In reply to ]
Hello, Joe,

The server doesn't start; stderr shows the following (captured with
"xterm 2> test.log"
This is regardless of the setting of "UseFBDev"

Following this is the generated xorg.conf. I see a strange "modeline"
entry for 720x400 --
could that be the problem? I believe that in the past I've deleted
this and even tried to replace
it with a 1024x768 line, but truthfully I can't remember any more.

Re: xorg.conf for Mac G4 mini [ In reply to ]
Further to the last;

I modified the xorg.conf to include a modeline for 1024x768, and
changed the
screen display sections to reference it. I believe the server gets a
little further now,
but still no soap.

Attached, the new xorg.conf and the error log (as before)

> EndSubSection
These modes are picked by xac (and probably the X server as well)
because if you look at the EDID reported by your monitor, these are the
modes it supports:
ET: [[720, 400, 70], [640, 480, 75], [640, 480, 67]] (the last
640x480 comes from the "DT" section which is the detailed timing)

How is your monitor attached? Does it produce a correct EDID elsewhere?

I looked up the model # (from the EDID) and it appears that you are
correct in using a 1024x768 default (although the manual suggests a 75Hz
refresh). In light of this, I would completely remove the "Modes"
section and "UseModes", "HorizSync" and "VertRefresh" lines from your
xorg.conf and keep the screen size at 1024x768. I would also add the the
line:
Option "IgnoreEDID" "True"
to the "Device" section to force the driver to ignore this incorrect
edid information.

Now, in the second email, it appears that X is starting properly,
perhaps there is an issue with your wm/desktop. Can you install a
minimal wm (like fluxbox or twm) and put that in your .xinitrc, then run
startx again? Does this bring you to a working desktop?
