fglrx multi-monitor configuration?
I've got a weird one for you guys... I hope you can help me figure this one out!
System:I'm running the latest Catalyst 9.4 (fglrx 8.6) from the repos on Ubuntu 9.04, on an RS780 (HD3200) which is integrated into my ASRock motherboard. There are two monitor outputs, VGA and DVI. I need to have them both operational (cloned) because for some reason the motherboard uses the only the VGA output for BIOS and POST display (which is frustrating) and I need to have access to those even though I am using the DVI output for my primary use.
With fglrx:With the standard vanilla xorg.conf created by aticonfig --initial, my DVI output does not work and I cannot enable it in Catalyst Control Panel. It does not appear as an option, only the VGA output is shown.
With radeon (open source):This is a bit odd to me, because when I use the latest open source (radeon) driver, I get proper cloned output live from both outputs simultaneously without having to configure anything. And that's with a nearly blank xorg.conf.
Manual config?I would start creating multiple Monitor configuration sections in xorg.conf to try to kludge it with fglrx manually, but I remember the ATI staff on here mentioning specifically that fglrx ignores xorg.conf and does all of its configuration in amdpcsdb... so it seems like the driver should automatically detect the outputs and make them available? I thought that manual configuration in xorg.conf was improper procedure nowadays.
How should I go about configuring this correctly and efficiently for simultaneous (cloned) output? I would like to avoid having multiple instances of X running if at all possible.
Thanks in advance for any help that you can provide!

AFAIK the BIOS should POST on whatever display is connected. Sounds like the BIOS or mobo thinks you have a VGA display connected even when you only plug in a DVI display. Is there any chance you have VGA connected but turned off ? If so then the BIOS might detect the analog load and post to the monitor even if was switched off.
Unfortunately, it does this even with nothing connected to the VGA port. From what I've been able to gather, it's some sort of glitch in the ASRock VBIOS code that doesn't allow native use of the DVI port.Originally Posted by bridgman
The ASRock support folks were actually quite spectacularly unhelpful and rude... here's their response to my original inquiry, and my exchange with them:
As you can see, they basically blew me off in a rude fashion. I suspect the root cause is that their onboard RS780 implementation is not properly configured in VBIOS. With any luck, it's probably some trivial oversight in the code.Dear ASRock Costumer,
The onboard video output DVI does not work as Primary Display adapter as you mention you want to display BIOS screen,therefore under this environment does not apply lower resolution .
Since the model of ASRock comes with (analog)regular VGA this is the primary display onboard adapter;therefore the DVI is secundary display under windows environment.
The ASRock model does not have any option to select DVI output as primary adapter default.
ASRock SupportDear ASRock Support,
I can accept not having BIOS display on the output. The problem is that it will not display ANY low-resolution output. Including the Windows recovery console (command line). Why will it not output VESA 640x480 at 60hz? EDID reports the mode as available and I do not have the problem with any other card on this monitor using DVI.
Thank you,
Jason PorterDear aSRock Costumer,
If you do accept the configuration of the motherboard ,please contact your vendor and return it.
Since the model is designed to work with the configuration I already explained before.
ASRock Support
Do you know of a way to dump the VBIOS code to examine it? Or can I provide it to you guys for fglrx (or AtomBIOS) development?
And in the meantime, should I go through the exercise of manually configuring the outputs in xorg.conf? Or should I not need to do that?
Thanks again!
That's kinda wierd; any chance there are two GPUs on the board ?
When they talk about "primary and secondary adapters" that usually implies either two GPUs or one GPU configured in multifunction mode (where it appears as two GPUs each with one display controller rather than one GPU with two display controllers), but I didn't think multifunction wes available with 780.
I have heard about a couple of mobos which have both 780 and onboard 3450, any chance you have one of those and vga is connected to 780 while DVI is connected to 3450 ? What is the exact model number of your mobo ?
The radeon driver sees it as a single display device with two outputs, and uses them both. The fglrx driver sees it as a single display device with only a VGA output.
I don't believe there is a 3450 on there... I've never seen anything like that reported in any of the logs, though I could be wrong. I can post my Xorg.0.log from both drivers if you need more info.
The board is an ASRock A780GXE/128M. The specs indicate:Integrated AMD Radeon HD 3200 graphics
- DX10 class iGPU, Pixel Shader 4.0
- Max. shared memory 512MB
- Integrated 128MB side port memory for iGPU
- Dual VGA Output: Support DVI-D and D-Sub ports by independent display controllers
- Supports HDCP function with DVI-D port
- Supports Full HD 1080p Blu-ray (BD) / HD-DVD playback
- Supports ATI™ CrossFire™ and Hybrid CrossFireX™
I'm not home to get a fresh one for you, but I happened to have an older Xorg.0.log file here from the system we're discussing, I'm not sure if it's relevant. I was using the radeon driver (6.10.0 maybe?) on Ubuntu 8.10 at the time, this is from January I guess.

Yeah, seems like a conventional motherboard alright. Strange...
Weird, eh? I'll get the log this evening under fglrx and see what it shows. Catalyst Control Center doesn't recognize a second (DVI) output as existing, I'm not sure if that's related to the xorg.conf configuration or something going on with the hardware.
Any ideas on the DVI not functioning as a native (driverless) display output? I would absolutely love it if it's something in the VBIOS that could be fixed.
Here is the current fglrx log for you, this is on the Catalyst "9.4" build in Ubuntu Jaunty. The lines are in the right order inside each section below but they are from selected areas of the log and many lines have been removed, these are obviously not the complete outputs. Let me know if you want the full, properly sequential Xorg.0.log instead.

I know this is somewhat OT for this thread, but for me this implies that for some adapters its possible to configure them somehow for multifunction mode?
Does this mean that they would appear as two completely different VGA Controller in lspci?
This would be very interesting in terms of multiseat support
