Does anyone have nvidia specific dual head functionality "twinview" working

This never worked on 4.0, 4.1 or 4.2 and it's with no surprise that I find
it doesn't work in 4.3 either.


Not true. I have been running twinview on every version of kde4 since 4.0.4
first escaped into the wild ...;-)

Is dual monitor support in KDE4 still a pipe-dream? I see lots of people on
every distro asking questions but nobody supplying any answers.

I couldn't live without a dual-head display now. I even had the IT department
at work install an upgraded video card and monitor on our workshop PC.


I can _occasionally_ get two working monitors by applying new settings on
the fly with nvidia-settings utility, but after saving the config this
setup *never* works once you startup a new desktop session. Manual configs
have the same issue. The second screen is black... but is receiving an
output signal.

Using the nvidia proprietary driver, the following sections from xorg.conf
should be a start:

Section "ServerLayout"
Identifier "Layout[all]"
Screen "Screen[0]" 0 0
InputDevice "Keyboard[0]" "CoreKeyboard"
InputDevice "Mouse[1]" "CorePointer"
Option "Clone" "off"
Option "Xinerama" "off"
EndSection

Section "Modes"
Identifier "Modes[0]"
ModeLine "1680x1050" 146.0 1680 1784 1960 2240 1050 1053 1059 1089
+hsync -vsync
ModeLine "3360x1050" 146.2 3360 1784 1960 2240 1050 1053 1059 1089
EndSection

Note: the modelines will be specific to your monitor setup.

Section "Screen"
Identifier "Screen[0]"
Device "Device[0]"
Monitor "Monitor[0]"
DefaultDepth 24
Option "RenderAccel"
Option "SaXDualHead"
Option "TwinView"
Option "SaXDualMonitorVendor" "SAM"
Option "SecondMonitorHorizSync" "31-81"
Option "SaXDualVSync" "50-75"
Option "MetaModes"
"1680x1050,1680x1050;1280x1024,1280x1024;1024x768,1024x768;800x600,800x600"
Option "SaXDualOrientation" "RightOf"
Option "SaXDualResolution" "1680x1050"
Option "TwinViewOrientation" "RightOf"
Option "SaXDualMode" "Xinerama"
Option "SecondMonitorVertRefresh" "50-75"
Option "SaXDualHSync" "31-81"
Option "SaXDualMonitorModel" "SAMSUNG"
Option "NvAGP" "3"
Option "DamageEvents" "True"
Option "UseEvents" "True"
Option "DisableGLXRootClipping" "True"
Option "AllowGLXWithComposite" "True"
Option "AddARGBGLXVisuals" "True'"
SubSection "Display"
Depth 24
Modes "1680x1050" "1280x1024" "1024x768" "800x600"
EndSubSection

EndSection

Note that I originally set it up with Sax2 (hence the Sax... parameter names).

As I said, the same basic config file has been working since 3.5.7, with some
minor tweaks for hardware upgrades along the way. I just don't let the nvidia
setup utility change it when I upgrade drivers.

There are instructions on the nvidia web site that I found useful for getting
it going (I just don't have the link handy at the moment; if I can find it,
I'll post it).
