Bonjour,
I run FC4 on my laptop with a nvidia graphic card. I use nvidia driver
from nvidia, but I think that the problem will be the same if I used
livna nvidia driver.
nvidia card is GeForce Go 6600
I want to connect a beamer and get display on both LCD panel and "CRT"
(beamer).
My LCD panel has 1280x800 resolution (15"4)
The beamer has 1024x768 resolution
First solution: use of TwinView; here is my xorg.conf file:
<snip> system configation
</snip>
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "LCD Panel 1280x800"
HorizSync 31.5 - 90.0
VertRefresh 60.0 - 60.0
Option "dpms"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "nvidia"
VendorName "Videocard vendor"
BoardName "NVIDIA GeForce Go 6600"
Option "TwinView" "on"
Option "MetaModes" "CRT-0: 1024x768 @1280x800, DFP-0:
1280x800"
# Option "NoTwinViewXineramaInfo" "off"
Option "HorizSync" "CRT-0: 50-100; DFP-0: 31.5-90"
Option "VertRefresh" "CRT-0: 60-120; DFP-0: 60"
Option "TwinViewOrientation" "Clone"
# Option "UseEDIDDpi" "FALSE"
Option "DPI" "90 x 95"
EndSection
<snip>
The last "option" has no effect; it is an attemp, without success, to
solve my problem: I want to have a full display on each "screen"; with
this configuration, display is correct on LCD panel but on projector
display parts are missing which I can display using the mouse.
Question: is it possible to have the same screen display, on LCD *and*
on bearmer screen?
Second solution: use of multiple screens; here are the parts I changed
in xorg.conf:
Section "ServerLayout"
Identifier "Multihead layout"
Screen 0 "Screen0" Above "Screen1"
Screen 1 "Screen1"
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Synaptics" "AlwaysCore"
Option "Xinerama" "off"
Option "Clone" "on"

EndSection
Section "Monitor"
Identifier "Monitor1"

</end>
With this configuration, I have two *different* screen: the Beamer is
above the the LCD panel (the mouse goes without any problem from one to
the other), each resolution is correct: I have full screen display on
both (Beamer and LCD) but the display is not the same: I can open a
graphical application on beamer which is not seen on LCD and
"vice-versa"....
I don't understand what is the meaning of the "Clone" option in
Section "ServerLayout"....
Is there a way to have exactly the same screen displayed, with different
resolutions, in order to have the same display on both display screens:
beamer and LCD?
I hope to be clear enough....
Thanks for help.
