Media PC won't boot/display to HDTV till lcd monitor is plugged in, xorg included


Hello, I am trying to build a media pc, and successfully so till this one little/big problem.

I want to be able to turn on my tv, and pc, and have the pc display onto the TV. Ports used are HDMI(pc)->HDMI(HDTV)

But for some reason Ubuntu will not fully load with just the TV plugged in (all i get is a black screen, not even a "no signal" message).Once a LCD monitor is plugged into the VGA port. Then I see a glossy white Ubuntu symbol on the LCD monitor. Then the Ubuntu loading screen appears on both the LCD monitor AND the TV... in mirror mode. And I can see the desktop on both monitor AND TV.

I am using an ATI RAEDON HD 4200 chipset that is on the mobo. I have downloaded the proprietary drivers and installed them. A few things I have tried are the instructions on this page, finding my modeline using a modeline calculator
https://wiki.edubuntu.org/X/Config/HDMI

and also going off of a suggestion from a thread on this website, stripping down my xorg file so that the Xserver would autodetect it. Which i think I did wrong because after that, it wouldn't display on TV at all.

Here is my last working copy of the xorg file.
Thanks in advance.

Have you installed the complete ATI Catalyst Control Center?

I think so, I can bring up a GUI and it gives me a bunch of options. Like looking at just the DVI monitors (TV) or the CRT monitors. There is a place to pick resolution and even disable monitors. When looking at the DVI section there is a place to add resolutions (listed @ 720p or 1080i ect).

Is there a more "complete" version?

You might check your BIOS settings. Sometimes a bios will not let you boot up without a monitor of some sort physically attached to the machine.

We have several machines at work that run as servers for virtual machines, with no keyboard or monitor and we had to change the bios in the base machine to allow them to boot properly.

Have you checked if the PCI output was the hot one and not the HDMI? I assume that there are both.

I don't know, how would I check something like that, and then set it?

This is my first install of Ubuntu btw :-) Gone pretty smooth till this issue I might add.

I did check the bios before posting, BUt I might have missed something crucial.

The bios can display on my tv fine ( don't know if that matters)

but all the options I get are
adv.
Power
Boot
Tools
Exit

in adv; the only thing promising is "Onboard Devices Config" and it only has options for Parallel ports and audio. There is also CPU config, chipset, and jumperFree config(which contains a lot of voltage and overclocking options)

Power is well... power.

Boot has device priority and an option called "Boot Settings Config" Probably the most promising section... but most disapointing
Options are: Quick boot (dis); Full screen logo (dis); AddOn ROM Display Mode (which I just changed to keep current, didn't even boot); wait for F1 if error and DEL message display to get to bios.

Tools has build in programs for launching a pre-OS browser (i think) and a bios flasher.

So I am thinking I am screwed unless this can be done through Ubuntu, because it seems like that is where it starts to hang, when Ubuntu tried to load.

thanks again for thinking this through with me.

I can't help, but am having a more severe problem, I can't even install Ubuntu on my machine because I'm only using HDMI via a TV.
The installer gets past the main menu to the loading screen then I get no signal at all.

Yeah I had the prob too... but having an extra 15 inch monitor was handy at solving that issue. plug a reg monitor in just for the install and you should be good.
