Dual Monitor: Wrong default Monitor

[kennyshell]

Hi,

I try to setup FC6 on my laptop computer to use it for presentations. It works so far, that I can display to seperate X screens on the laptorp LCD and an external conected LCD. However, the main screen (the screen for login, working, notes... just the non-public screen) appears always on the external connected screen. I would like to have it the other way around. It works all fine within Windows XP, so I suggest there is nothing wrong with the hardware.

TwinView (one big screen over 2) works fine. Main screen is on the main screen.

It seems that I am the only one in the "holy" google to have this problem. I also tried to look it up under x.org and other distribution. Just nothing. Hope anybody can help me solve this problem.

I tried to rearrange the main screen and the external screen in my xorg.conf in all possibilities. It doesn't work. Well, both screens are on, but the main is on the wrong one.

Details:
Laptop: Littlebit Racoon Z75
Graphic card: Nvidia GeForce Go 6600

I did install FC6, all updates done till today, incl. newest nvidia driver from yesterday (no longer beta).

I even tried options like:

• Option "MonitorLayout" "LVDS,TMDS"
• Option "ReverseDDC" "on"

I got this from: ftp.x.org...

Option "ReverseDDC" "boolean"
When BIOS connector informations aren't available, use this option to reverse the mapping of the 2 main DDC ports. Use this if the X serve obviously detects the wrong display for each connector. This is typically needed on the Radeon 9600 cards bundled with Apple G5s. The default is off.

and ubuntuforums.org

Option "MonitorLayout" "primary monitor, secondary monitor"
#replace primary monitor with these (from man radeon):
NONE -- Not connected
CRT -- Analog CRT monitor
TMDS -- Desktop flat panel
LVDS -- Laptop flat panel

Thx for any help with this.... ehm "strange" problem.

Here is my xorg.conf file. Screen0 is the Main Screen, which should appear on my laptop:

kennyshell,

I had a similiar problem with a desktop connected to two monitors. If they were both plugged in, it would always go to the vga output, instead of the the dvi output.

I found there was a graphics config program for Nvidia, have you tried running "nividia-settings' from a terminal window?

I still had to play with things, I could save the settings on from the secondary monitor, the program window would not completely display correctly, so I had to boot with one monitor conected and then hotplug the secondary. I then recieved some error messages when started nvidia-settings, but after getting everything saved correctly, I can launch it with no errors. Now my main log on screen is the Primary monitor.

Hope this helps a bit.
PS I backed up my xorg.conf before trying anything, of course.

Hi baysailor,

Thx for your comments.

Yes, I already used nvidia-settings, but it didn't work. I tried to launch it from the shell, as you said, and I get some error messages now: It says it can't write X config file. When I configure the monitor settings through system-config-display I can setup he 2 screens (after reloading x-server). The default screen is still on the wrong one, as expected.

If I run nvidia-settings now from the shell I got some more errors:

(a few times thsi error on different lines)
Invalid display device DFP-0 specified on line 19 of configuration file 
'/root/.nvidia-settings-rc' (The currently enabled display devices are 
CRT-0 on localhost.localdomain:0.0)

Huge ?

I googled it already, but didn't find anything usefull. I will see how I go on with this. I don't have much spare time right now, so it may take some time to do it.

I also tried to set it up with SuSE, but SuSE destroyed itself, when I tried to setup the nvidia driver according the official SuSE way (aaiihhh). So I am waiting for Mandriva 2007 now. I want to know if it is a FC6 problem or not before I go ahead.

Cheers,
flex

is their a function key on your laptop to switch the primary monitor, i know mine has one(fn F5), but it has to be switched before the system boots
