Dual Monitor Help.

[medicineman]

So I'm using Lenny, trying to get dual monitors set up. I'm not sure on the correct steps, but have done some googlin' and wasn't finding what i was looking for. (could be that i just missed it)

lspci:

01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series]
01:00.1 Display controller: ATI Technologies Inc RV516 [Radeon X1300 Pro] (Secondary)

If someone would be kind enough to help me set this up, I would greatly appreciate it. Let me know if you need the output from any other commands.

Thx,
MedicineMan

I don't have two monitors myself, but I read that you have to modify the file /etc/X11/xorg.conf. You have to specify that you are using two video adaptors in that file.

This link may help you.

Code: Select all

Section "Device"
  Identifier "ATI Technologies, Inc. Radeon 9200 SE (RV280)"
  Driver "radeon"
  BusID  "PCI:1:0:0"
  Option "RenderAccel" "True"
  Option "SubPixelOrder" "None"
  Option "ColorTiling" "False"
  Option "MergedFB" "True"
  Option "MetaModes" "1024x768-1024x768 1024x768-1024x768"
  Option "MergedDPI" "100 100"
  Option "CRT2Position" "Below"
EndSection

According to my logic, you have to change BusID to match yours and any other relevant item.

I hope that link helps you.

My google search criteria were: xorg.conf "multiple monitors" +debian -ubuntu

Personally I think it's easier to get dual monitors to work with xrandr.(Howtos here and here). I used to run 19"+15" with a quite basic xorg.conf (just remember to add virtual to the Screen section)

Code: Select all

Section "Screen"
	Identifier "Screen"
	Device     "Card0"
	SubSection "Display"
		Virtual   2304 1024
		Depth     24
	EndSubSection
EndSection

And then I ran this when I started X

Code: Select all

xrandr --output DVI-1 --off 
xrandr --newmode "1280x1024_75.00"  138.75  1280 1368 1504 1728  1024 1027 1034 1072 -hsync +vsync 
xrandr --addmode DVI-0 1280x1024_75.00  
xrandr --output DVI-0 --mode 1280x1024_75.00 --output DVI-1 --mode 1024x768 --pos 1280x0
