GDM login on wrong Monitor

[NoOneElse]

Ok I have 2 monitor on and Nvidia FX5200 set up as twinview

Monitor 1 is an old Sony CRT @ 1280x1024
Monitor 2 is a Visio HDTV @1920x1080

I have setup Monitor 1 to be the primary using nvidia-settings but the GDM login keeps sowing up in the second monitor ; before the HDTV I had a CRT TV @ 1024x768 and all was good.

My theory is that GDM determines the center of the Screen (both monitors together) and then centers on that monitor.

If this is true then how may I override this behavior and force the GDM login to show on my primary monitor?

Any help is appreciated

Thanks

Well, on my machine the default appears to be chosen by which monitor is plugged into port 0 on my video card.

[NoOneElse]

is the monitor port 0 a larger resolution than the one in port 1 ?

Then how do I know which is port0,1,2,4 DVI-A,DVI-D,S-video,VGA ???

I'm currently using DVI-A a.k.a. DVI->adapter->VGA for my HDTV and the VGA to my Sony CRT

xrandr --auto --output VGA-0 --mode 1680x1050 --right-of LVDS
xrandr --auto --output VGA-0 --mode 1680x1050 --left-of LVDS

Using xrandr (the same thing as using your video display GUI) you can change the position of the monitors.

In the man pages there is also the option "primary"

xrandr --output DVIA --primary

Maybe it works I didn't try.

And you can find a lot about your video settings using xrandr to query the system for you:

xrandr
xrandr -q
xrandr --prop
xrandr --verbose

Ok I physically reconnected my monitors to change their priority no success

Now I found a SIMPLE was to get around this:

Simply move your mouse to the monitor you want the GDM greeter to show and press Enter; IS THAT SIMPLE!!!

Sorry to bring up an issue from an old thread, but How is this solved for you? I still have the same issue as is described in the OP; while, your "workaround" "works" when you want to use the lockscreen and re-enter the session, gdm by itself is still to dumb to know any better when switching users or when autologin is turned off. There are mentions of some other "workarounds" to move the file "~/.config/monitors.xml" to "/var/lib/gdm/.config/"; however, in fedora20 this has no effect.

At first, I assumed that the file-ownership was the problem; so, I changed the permissions from "root:root" to "gdm:gdm". Once again, though, no difference in behavior. Has anyone else gotten this to work? How do I get gdm to stop choosing the external Monitor as the primary monitor and/or at least to stop using the second monitor altogether? Anyone? pleasseee!!!

P.S. I see the variable "$GDM_PARENT_DISPLAY" repeatedly in the file at "/etc/gdm/Init/Default", but I have no clue what its exactly referring to?

I've "resolved" issue following some advice I found in the mailing-list (gdm-list?); namely, following the previously-mentioned resolution of copying monitors.xml file from "~/.config/monitors.xml" after I've turned off the second monitor. Once the second monitor is turned off in "Settings">>"Displays", the monitors.xml file is re-written to "~/.config/monitors.xml" to reflect the changed configuration. Then, copying over that file to "/var/lib/gdm/.config/" takes affect with gdm. Hope this helps someone else in this predicament.

Thanks, that worked great (with the Nvidia driver I couldn't get the old way with with xhost and control-center to work).
