No picture in X (DVI-I analog) on MacMini [regression][patch]

For reference, here's the log output from my working X setup on Intrepid.

Please try the -ati/-radeon packages from my PPA https://launchpad.net/~tormodvolden/+archive/ppa (xserver-xorg-video-ati - 1:6.12.1.99+git20090327.f061308e-0ubuntu0tormod)

Is there a tool to inject a package update into a live CD image, or do I need to unpack
the image, use dpkg --root, and then recreate the ISO (including El Torito and whatnot)?

Ah, never mind, I found https://help.ubuntu.com/community/LiveCDCustomization which
contains all the needed info. I'll check the package tonight.

You don't need to change the live CD. Just boot it with Safe Graphics Mode (vesa or whatever works on the G4) and download and install the package, edit xorg.conf and restart X.

If there's no Safe Graphics Mode, you can boot with the "text" option and install it on the command line, before running X with "startx".

Tormod,

Your PPA does not seem to contain any PPC builds of the package you indicate.
I tried building it myself, but it build-depends on a newer xserver-xorg-dev than
what is available in Intrepid...

Sorry, I keep forgetting this is powerpc :) You can relax the xserver-xorg-dev dependency in debian/control, just exchange 1.6 for 1.5.

Well, ok, I used "-d" to circumvent the dependency check completely, but it doesn't look like building with
this version of xserver-xorg-dev gived the required results, because the packages produced were not
usable with the X server on the live CD.

The -radeon package could not be installed; the message I got was:

 xserver-xorg-core conflicts with xserver-xorg-video-4
  xserver-xorg-video-radeon provides xserver-xorg-video-4 and is to be installed.

The -ati package could be installed, but trying to use it resulted in:

[ 0.002714] (==) Using config file: "/etc/X11/xorg.conf"
[ 0.186018] (EE) module ABI major version (4) doesn't match the server's version (5)
[ 0.186058] (EE) Failed to load module "ati" (module requirement mismatch, 0)
[ 0.186072] (EE) No drivers available.

I need to sleep now. If you have any suggestions, I'll be happy to try them tomorrow. :-)

If the driver is built for 1.5 it only works on 1.5... I suggest you build it from the live CD if you can. Or install Jaunty to a separate partition or disk...

Ok, building from the live CD worked fine.

The actual driver upgrade seems to have made no change though; the behaviour is
exactly as before.

Attaching logs.

Can you please also try
 Option "MacModel" "mini-internal"
in the Device section of your xorg.conf? See "man radeon" for more information. The driver detects "external".

I've forwarded this bug upstream for you to https://bugs.freedesktop.org/show_bug.cgi?id=20979 . Could you please subscribe yourself to this bug, in case they need further information or wish you to test something. Thanks ahead of time!

Selecting mini-internal makes no difference.
Also, my working X setup on Intrepid auto-detects "mini-external" as well.
Not that this is any proof it is correct of course. :-)

I've subscribed myself to the upstream bug, although it looks like someone already has
had some kind of revelation... :-D

Thanks for your help so far.

It seems like Alex has sorted it out. I have uploaded a new source package to my PPA.

Yep, now everything seems to work perfectly.

I'll try building a custom live CD with the packages
I build tomorrow just in case...

Very good. So these two commits are needed:
