Hi
I have a setup which I've just upgraded to Fedora 13 with Xorg server
1.8.0. The setup has a Quadro FX 3400 card with an IBM T221 3840 x
2400 monitor.
Under previous iterations of xorg i've output to the monitor as a
dualhead setup using 1920x2400 + 1920x2400 and it's worked pretty
well.
However under the new version of Fedora the xorg.conf file now gets
re-generated every reboot using udev to detect devices if I've
understood the docs properly.
Unfortunately the display is getting detected as a 3840x2400 screen
and is being output to at the wrong refresh rate, 50 hz rather then 25
hz, at least according to xrandr -q, and as a result the screen is
blank. The xorg session is running however as I can vnc into it and
it's running fine. I am using the nvidia driver from rpmfusion.
Given that xorg.conf is re-written every reboot how can I add both a
modeline and dualhead type config so that it 'sticks' after a reboot?
Thanks in advance.
As a follow up to my earlier mail I've found that you can now put the
xorg.conf in /etc/X11/xorg.conf.d and it will get read from there so
that's solved that problem.
My new problem is slightly different in that as the display is treated
as two screens how do I get the screen background and panels to spread
across as a single screen?
i.e. at the moment my desktop background is shown as two identical
images one on each screen, what I want is one background image spread
across both screens. Also any panels are limited to one screen rather
then being spread across both screens.
I know ATI had a concept called 'Big Desktop' for these situations but
I could never get it working, does anyone have any ideas or
workarounds to get it working now with an NVidia card?
Thanks in advance.

look for a "twinview" setting in your nvidia-settings panel, if having
trouble finding the nvidia-settings via the GUI just open a terminal and
type "gksudo nvidia-settings" and you are operating a better instance than
you get from the menus in the (gtk) GUI anyway, at least after re-entering
your password (provided you are member of wheel).
(in GUI should be "System->Administration->NVIDIA X Server Settings", in
there should be "X Server Display Configuration", look for button
"Configure..." to right hand side - this gives you a situation where the
picture you are saving by pressing enter after pressing 'printscrn' is the
full width of both displays sum width.)
twinview is the closest I have seen to what you are asking for, is it
available to you?
Hi Robert
Twinview gives you the two duplicated desktops. I'm looking for a
'Big Desktop' mode where the driver treats two displays as one
complete desktop.
Regards
That's odd, I'll double check at work when I get there in about an hour
and a half but from here I'd swear I've got our electronics engineer on
a dual monitor setup using twinview which gives him a desktop 3840
pixels wide by 1080 high covering two matched monitors set at 1920x1080
each.
When he presses 'prntscrn' (Ubuntu 10.04, NVidia driver) he gets a PNG
that is 3840x1080 where-ever he chooses to save it - will repost from
work after verifying this, but he can also spread anything (window type)
across both displays.
Anyone else wanna let us know what they get when they choose 'twinview'?
(*And restart-x!)
