On Sep 19th my MacMini PowerPC was upgraded from xserver-xorg-video-ati
1:6.6.193-1ubuntu1 to 1:6.7.192-4ubuntu1. After rebooting, gdm couldn't
detect the Xserver running. Later, upgrading to 1:6.7.193-1ubuntu1
didn't make a difference.

I tried to dpkg-reconfigure xserver-xorg with no luck. Only downgrading
to 1:6.6.193-1ubuntu1 gets rid of the problem.

My Dell 2005FPW LCD screen is connected to the MacMini through a DVI
cable and my card is a "VGA compatible controller: ATI Technologies Inc
RV280 [Radeon 9200] (rev 01)" per lspci.

Xorg.0.log using latest git code

Just compiled and tried xf86-video-ati from git master (commit
5a6f74103f0ec0d451d0e2573442efe5922848af) and it doesn't work either.
I'm attaching the Xorg.0.log.

The mac mini needs a custom connector table like most other macs.
What connectors does it have? based on apple's web site, it looks like
it has just a DVI port that can drive DVI or VGA or tv-out (via DVI
adapters).  I'm guessing it uses internal TMDS and the TV DAC.  The
question is what ddc line it uses.  Does adding the following option
in the device section of your config help?

Option "ConnectorTable" "X,1,0,3,0,1,2,6"

replace X with 1 or 2 or 3 or 4 or 5 until you get DDC working.

Once we sort this out, I'll add a MacModel option for the mini.

Mine has just a DVI port with a DVI-to-VGA adapter.

I tried the ConnectorTable option with 1..5 values without success.  All
values seemed to have the same result:

...
(EE) RADEON(0): No valid modes.
(II) UnloadModule: "ati"
(II) UnloadModule: "radeon"
(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found

However, for X=4 X didn't end with an error though the screen went to
sleep mode (I guess that's because it was receiveing bad values).

I kept all 5 Xorg.0.log files; let me know which one would help or
whether I should try different values in ConnectorTable.

Thanks a lot!

perhaps it's using external TMDS, try:

Option "ConnectorTable" "4,1,1,3,0,1,2,6"

So to confirm, Option "ConnectorTable" "4,1,1,3,0,1,2,6" (external TMDS)
fixes the display for you?

Also is this with DVI or VGA connection?

The attached Xorg.0.log confirms that Option "ConnectorTable"
"4,1,1,3,0,1,2,6" (external TMDS) fixes the DVI-to-DVI display on my
MacMini.

Excellent.  Fixed upstream: 81114af1cdddc0b10d076f2e38c7a00c1223cc48

With ati git master
Option "MacModel" "mini"
should do the right thing automatically.
