Hello All,

I have a dual monitor station with Nvidia card.
I've installed the latest Nvidia drivers from their site (X didn't come up with what was with VL standard 5.Cool.

I see one screen very good, however I can't get the 2'nd screen to show anything.

Can someone have a look at my xorg.conf and tell me what I'm doing wrong?

Thanks,
Miki

Your nvidia card needs to be twinview capable, does it?
Also check if it is a regular pci or an AGP card.

The only thing I see on your xorg.con is:

Quote
Section "ServerLayout"
    Identifier     "X.org Configured"
    Screen      0  "Screen0" 0 0

I think it should be:

Code:
Section "ServerLayout"
  Identifier     "X.org Configured"
  Screen      0  "Screen0" 0 0
  Screen      1  "Screen0" RightOf "Screen1"

Check this: http://gentoo-wiki.com/HOWTO_Dual_Monitors#Configuring_X

Let us know if this solves your problem...

Thanks! I can now see both monitors.
(Minor fix, it should have been
Code:
    Screen      0  "Screen0" 0 0
    Screen      1  "Screen1" RightOf "Screen0"
swap 1 and 0 in screen names)

However I can't drag windows between them. xfce recognizes the 2'nd screen and I can change the background and such (there is no panel or trash there though).
When I try to drag a window to the right, it just moves to a virtual workspace instead).

Any ideas?

Thanks again,
Miki

Forget my last question, added
Code:
        Option "Xinerama" "true"
To "ServerFlags" and it works.

Great forum, love it!

FWIW, I'm writing the steps which made this possible:

  • Install VectorLinux (5.8 standard in my case)
  • Install Kernel sources
  • After installation X won't come up
  • slapt-get --update
  • slapt-get --upgrade
  • Get latest Nvidia drivers from http://www.nvidia.com/object/unix.html
  • chmod +x NVIDIA-Linux-x86-100.14.11-pkg1.run
  • ./NVIDIA-Linux-x86-100.14.11-pkg1.run(this will compile and install it)
  • Edit /etc/X11/xorg.conf to something like the below
  • Enjoy

the only way to have two monitors in linux is by configuring the xorg.conf? is there any program for this task?

I have configured dual monitors in VL using both the ATI and nVidia GUI control panels which come with the proprietary drivers.

It also worked for me. A couple of tips; running from the standard menu (System > NVIDIA Server Settings) had no write authority in /etc/X11, so I opened a shell, su'd to root and then ran nvidia-settings. Also I got the best results by choosing mode TwinView.
