Ok, it's definitely DDC_DVI. There's a chance apple used external
tmds, but I doubt it. You can try the attached patch. I suspect
internal tmds support may just be broken in the driver for some
setups. I haven't tested an r1xx card in a while.

These two behave exactly like DDC_CRT2.
I attach the dmesg output and the X logs for all four cases.
Thanks again,

Ok, it's definitely DDC_DVI. There's a chance apple used external tmds,

Doesn't work. Yaboot screen appears, and briefly (~1 second) the first boot
screen. Then the display flickers, and the shades/lines/pixels appear while
the box is booting (in text mode). When X starts, the display flickers
again, resetting all the garbage, which then appears again.
I suspect internal tmds support may just be broken in the driver for some
setups. I haven't tested an r1xx card in a while.
Anything I can test there? Where?
Sounds like internal tmds may be broken in kms. Probably easiest to
dump the registers from a working setup (console fb, or old version of
the driver) and a non-working setup (driver with the attached patch
applied). Then send me the output. You can use radeonreg available
here:
http://cgit.freedesktop.org/~airlied/radeontool/
As root, in a working setup run:
./radeonreg regs radeon working.regs
then switch to the broken setup and run:
./radeonreg regs radeon broken.regs

I use a digital Formac TFT, i.e. the kernel connector would be (I think) the
'DFP1' channel of 'DVI-I-1'.
Starting with Ubuntu 9.10 (radeon driver 6.12.99), I had to use the Device
option 'Option MacModel mini-internal'. Otherwise, the display showed
only single pixels, sometimes a blue vertical line, and a greenish shade in
some regions. This was apparently caused by an incorrect connector table
(i.e. the video signal applied to the wrong output connector), and fixed by
this option. However, version 6.99.99 just ignores it (according to the
log), and I only get the pixels/line/shades again. Any idea how I could fix
this with this driver?
With KMS the display setup is handled by the kernel now, so the
MacModel option has been replaced with a kernel module parameter.
Specify radeon.connector_table=x where x =
enum radeon_connector_table {
CT_NONE = 0,
CT_GENERIC,
CT_IBOOK,
CT_POWERBOOK_EXTERNAL,
CT_POWERBOOK_INTERNAL,
CT_POWERBOOK_VGA,
CT_MINI_EXTERNAL,
CT_MINI_INTERNAL,
CT_IMAC_G5_ISIGHT,
CT_EMAC,
CT_RN50_POWER,
CT_MAC_X800,
CT_MAC_G5_9600,
CT_SAM440EP
};
However, it would be better to add a proper table for your specific
model so that you won't have to force some table. Please send me the
output of lspci -vnn and the output of /proc/cpuinfo and I can prepare
a patch for you to try.

My card doesn't have a TV output, but an analogue vga (in addition to the adc which has both digital and analogue signals). ADC is basically an apple proprietary DVI-I port. We add the tv-output because IIRC Apple sells a ADC to TV adapter. MINI_INTERNAL is not the correct option, it just happens to work better than the default connector table. I'll attaching a patch to test. It would be great if you could test both connectors to make sure I got the ddc lines mapped correctly (make sure you can get an edid from the monitor). The hardest part is getting the ddc line mapping correct. I've included several options in the patch for each connector, e.g., + /* DVI-I - tv dac, int tmds */ + ddc_i2c = combios_setup_i2c_bus(rdev, DDC_CRT2, 0, 0); + //ddc_i2c = combios_setup_i2c_bus(rdev, DDC_DVI, 0, 0); + //ddc_i2c = combios_setup_i2c_bus(rdev, DDC_VGA, 0, 0); + //ddc_i2c = combios_setup_i2c_bus(rdev, DDC_MONID, 0, 0); and + /* VGA - primary dac */ + ddc_i2c = combios_setup_i2c_bus(rdev, DDC_VGA, 0, 0); + //ddc_i2c = combios_setup_i2c_bus(rdev, DDC_DVI, 0, 0); + //ddc_i2c = combios_setup_i2c_bus(rdev, DDC_CRT2, 0, 0); + //ddc_i2c = combios_setup_i2c_bus(rdev, DDC_MONID, 0, 0); comment or uncomment lines to try different ddc line mappings until you find which line is mapped to which connector.
