...or at least partially... after banging my head against the screens (the wall hurts more :P) I removed all nVidia-related stuff from my PC and started over by restoring the original xorg.conf file (backed up as xorg.conf.install) Added the nVidia repos to YaST2 and installed nvidia-gfxG02-kmp-default-256.35_k2.6.34.0_12-14.1.x86_64 and x11-video-nvidiaG02-256.35-15.1.x86_64. After the first XDM restart I only had one active screen with an ugly resolution... then I just executed, as root of course: nvidia-xconfig --twinview to enable TwinView... no trace of Xinerama at all... and then: /etc/init.d/xdm stop and again: /etc/init.d/xdm start and it works !! dual-head is enabled, the Xorg process isn't eatting up the CPU as before, the Composite effects are enabled, etc... there are still some minor glitches, like the "wobbly windows" effect not working 100% smooth by now, but I can always deactivate that and enjoy the rest... I assume that the "--twinview" above did the trick, at least for my scenario, so we can state that KDE4 is capable of dual-head and TwinView... I haven't tried Xinerama yet but TwinView seems to perform better... so I won't give it a chance at all... :-) Anyway, here's my xorg.conf file for the sake of completeness: -- # cat /etc/X11/xorg.conf # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 256.35 (buildmeister@builder97.nvidia.com) Wed Jun 16 19:15:05 PDT 2010 Section "ServerLayout" Identifier "Layout" Screen "vboxvideo" 0 0 Screen "vmware" 0 0 Screen "cirrus" 0 0 Screen "fbdev" 0 0 Screen "vesa" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "keyboard" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 28.0 - 33.0 VertRefresh 43.0 - 72.0 Option "DPMS" EndSection Section "Device" Identifier "vboxvideo" Driver "nvidia" EndSection Section "Device" Identifier "vmware" Driver "nvidia" EndSection Section "Device" Identifier "cirrus" Driver "nvidia" EndSection Section "Device" Identifier "fbdev" Driver "nvidia" EndSection Section "Device" Identifier "vesa" Driver "nvidia" EndSection Section "Screen" Identifier "vboxvideo" Device "vboxvideo" Monitor "Monitor0" Option "TwinView" "True" Option "MetaModes" "nvidia-auto-select, nvidia-auto-select" SubSection "Display" Modes "nvidia-auto-select" EndSubSection EndSection Section "Screen" Identifier "vmware" Device "vmware" Monitor "Monitor0" Option "TwinView" "True" Option "MetaModes" "nvidia-auto-select, nvidia-auto-select" SubSection "Display" Modes "nvidia-auto-select" EndSubSection EndSection Section "Screen" Identifier "cirrus" Device "cirrus" Monitor "Monitor0" Option "TwinView" "True" Option "MetaModes" "nvidia-auto-select, nvidia-auto-select" SubSection "Display" Modes "nvidia-auto-select" EndSubSection EndSection Section "Screen" Identifier "fbdev" Device "fbdev" Monitor "Monitor0" Option "TwinView" "True" Option "MetaModes" "nvidia-auto-select, nvidia-auto-select" SubSection "Display" Modes "nvidia-auto-select" EndSubSection EndSection Section "Screen" Identifier "vesa" Device "vesa" Monitor "Monitor0" Option "TwinView" "True" Option "MetaModes" "nvidia-auto-select, nvidia-auto-select" SubSection "Display" Modes "nvidia-auto-select" EndSubSection EndSection -- Regards, Martin ----- Original Message ----

in fact, KDE4 can smoothly do dual-head + Xinerama. I had it up & running in the not-so-distant past with OpenSUSE 11.0 + KDE4.x (can't remember now what "x" was) so that's why I was so annoyed when I saw that
it won't work as smooth (or even better!) on 11.3 ...
Anyway, I'll try some other combinations when I go back home this afternoon and
I'll keep you posted. Yesterday night I was able to have all the missing KDE4
effects and use the nVidia GPU using a one-monitor-only configuration... when I
turned Xinerama on and restarted X the magic vanished... :-/ so I guess I'm getting closer. Posts like this one http://www.nvnews.net/vbulletin/showthread.php?t=69166 might shed some light...
Regards, Martin

They're wrong - I've been using it with dual screens since 4.0.4 and it works perfectly (provided you don't want to stretch one panel across both screens).
The thing is that each screen has a separate desktop activity with its own plasma setup (I haven't tried it with a plain i.e. non-plasma setup) but if you don't mind this (and I don't) then I can't find any other drawbacks.
In fact, I kind of like it like that because I can have separate backgrounds on each screen (it just so happens that they're photos of my kids).
I use an nvidia 9400GT with the latest binary drivers and have xinerama setup in my xorg.conf file. I have had the same setup since 3.5.8 (previously using an FX5500).
I do think that performance may have been slightly better with the 195.36 drivers than the current 265.xx drivers but I haven't yet switched back to confirm that.
Anyway, the point is that dual-head on nvidia on KDE4 works great. Anyone who says it can't be done should go back and re-read the nvidia docs.
