ATI Radeon 7000 Dual Monitor setup with LXDE and xf86-video-ati

Hello!

I have this Dell Dimension 8250. I've loaded it up with Arch Linux with 2 monitors hooked up to a VGA and DVI output(One 1280x1024, other is 1024x768). Although, only one monitor is detected(VGA) and the other is completely neglected by the system. It really shouldn't be because the boot screen comes up on the one that is blank after boot. The monitor is not cloned, but is simply not detected by the system and is blank. Any input on getting it to work correctly would be appreciated.

Here is some various system information

System: Dell Dimension 8250
Arch Version: Arch Linux 3.14.2-1-ARCH (tty1)
Video Processor: ATI Radeon 7000 128mb
RAM: 256mb RDRAM
Processor: 2.4ghz Intel Pentium 4 512kb cache
Bootloader: GNU GRUB version 2.02~beta2
Other Operating Systems installed: Windows XP Professional, Windows 98 Second Edition
Video Card Driver: Open source xf86-video-ati (latest from official repositories)

The card does support 2 monitors. In fact, I believe it's one of the first of its kind to implement dual monitor support into a consumer card(not sure though). I've tested with both XP and 98SE to confirm.

Thanks!

Re: ATI Radeon 7000 Dual Monitor setup with LXDE and xf86-video-ati

What is the output of xrandr -q?

Here ya go....I believe it simply states that it finds that VGA-0 is plugged in and running at a native resolution of 1280x1024 and DVI-0(which is actually plugged in) is not plugged in aswell as S-video.

Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 4096 x 4096
VGA-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 338mm x 270mm
1280x1024 60.02*+ 75.02
1280x960 60.00
1280x800 74.93 59.81
1152x864 75.00
1280x768 74.89 59.97
1024x768 75.08 70.07 60.00
1024x576 59.97
832x624 74.55
800x600 72.19 75.00 60.32 56.25
848x480 60.00
640x480 75.00 72.81 66.67 60.00
720x400 70.08

DVI-0 disconnected (normal left inverted right x axis y axis)
S-video disconnected (normal left inverted right x axis y axis)

Go ahead and try

xrandr --output VGA-0 --auto --output DVI-0 --auto --right-of VGA-0

No cigar. I printed xrandr -q after this and it still stated that DVI-0 was disconnected and I still had a blank screen. I tried as sudo, as well.

Do you have any EDID output in /var/log/Xorg.0.log?

There is EDID output for the VGA, but there is no EDID for DVI.

This sounds silly but power cycle the monitor attached to DVI, there have been times when this works.

Didn't work. In fact, I swapped the monitor ports and it still would not display on the VGA monitor. Is there a way to force output through DVI?

You can try

xrandr --output VGA-0 --off --output DVI-0 --auto

but you may have to switch back to the console.  Doesn't lxde have a randr setting program or am I having a brain fart?  Brain -- use only as directed.  Side effects may include nausea, headache...

"Can't open display." I believe it does, but it is just very basic and doesn't allow you to output to a monitor it can't detect.

"Can't open display."

After you run it from the lxde, it'll probably all blank out on you, in which then you'd have to switch back to the console.

Nope, sadly it didn't work. Do some old monitors require drivers in Arch?

Also, I've recently noticed that the screen cuts of on the right and around 5 columns of pixels on the left are being unused. X doesn't really like old cards, does it

Actually I've got an old card with two outputs RV100, and it does it ok in WinXP, along with the onboard Intel, but the manufacturer didn't make drivers for Win7.  I can sort of get it to work under linux, 2 out of 3 monitors isn't bad.

Isn't the 7000 a variant of the RV100?

Yeah, I can get either it or the onboard to work or the RV100, but not really both at the same time.  I can get both screens on the RV100 to duplicate each other with the onboard, and them to extend from one to the other without the onboard, but not all three at the same time.

You probably have ati-dri installed, since it has worked up to this point.
