Hi,

Okay, understood.

  AFAIK, DELL has cards with two DVI-D outputs and with two VGA outputs (all
  from a dangle). It appears if the 2nd head is connected to a CRT, some
  register bit (CRT2_ON?) has not been set correctly and you'll get a blank
  screen. If the 2nd head is connected to a DFP, it's totally not handled. I'm
  not sure when someone (or myself) can have time to have this support added.

Yep, that's what I am seeing, I'm getting a blank screen on the 2nd CRT
monitor.

  Not sure what kind of card you have, maybe you can help to debug it :-)

I would be more than happy to help. We purchased this model because I
thought Radeon VE was supported by XFree, and I'm sad seeing my 2nd
monitor blank :)

Here's what the driver find about my card:
(--) RADEON(0): Chipset: ATI Radeon VE (AGP) (ChipID = 0x5159)
(--) RADEON(0): Linear framebuffer at 0xf000
(--) RADEON(0): MMIO registers at 0xff9f
(--) RADEON(0): BIOS at 0xc100
(--) RADEON(0): VideoRAM: 32768 kByte (64-bit DDR SDRAM)
(II) RADEON(0): PLL parameters: rf=2700 rd=60 min=12000 max=35000; xclk=18300

Not sure how I can help, but if you can direct me I'll do my best.

Regards,

Stephane

  x420 supports VE dual-head setup. However if you are using some OEM version
  of VE card (like DELL's) you might be out of luck.

Can you explain this a little more further ?

Do you mean that the OEM chip isn't supported by the XFree driver ?

I did some test on DELL's OEM Radeon VE card with a 4.2.0 XFree86, and
both cards get initialized, but 2nd screen remain with no signal.
