Multiple LCD Displays via D/Dock D/Port

[Outlaw_Wizard]

Gentlemen,

Been working with Fedora9 i386 on a Dell M70 and Fedora9 x64 on a Dell M90. In both cases I followed the directions for installing the Nvidia drivers via yum listed in an earlier thread. In both cases the systems embedded display is working beautifully.

But...

My standard work environment is via a D/Port (port replicator with DVI and VGA, for the M70) or D/Dock (Docking Station with DVI and VGA for the M90), in both cases driving a pair of NEC 19 inch LCD's (1280 x 1024 native at 24 bit color depth). Neither system will drive the external displays when booted while attached to the Port Replicator or Docking Station. The M90 was OS loaded while docked, and was working on the DVI display up until I added the Nvidia drivers.

Modifying my xorg.conf has not worked to date (see attached), and seems to be over-written in any case across boots...

I'm a noob with Fedora and it's graphical interface, but reasonably well experienced with various *nix versions (mostly Solaris) from the command line...

I too just installed Fedora 9 on my Dell D820 with nVidia display. I am also running a docking station connected to a DELL 2407WFP monitor.

Like you, I cannot get the monitor to work when Fedora boots while connected to the docking station. I have to go into the nvidia settings, enable the monitor. This is a PITA though. Also, when I try to save the new Xorg file, I get an error message:


Unable to create new X config backup file '/etc/X11/xorg.conf.backup'.


Any idea how we can get our external displays to work?

Unable to create new X config backup file '/etc/X11/xorg.conf.backup'.
This message could be because only root user can edit the conf file.

open the nvidia settings from terminal.
sudo nvidia-settings

now do the necessary changes and save and restart the gnome session (ctrl+alt+backspce)

Yup, I tried that (on accident) and everything saved, and appears to be working. Now onto other issues.

thanks for the quick help.
