oS 11.4 64-bit KDE 4.8.4, nvidia driver 2.9.5, twinview mode, two monitors - one DVI (primary), one VGA:
In system-settings>screen and monitor there are four tabs (or page icons): size & orientation, screensaver, gamma and various monitors (translated from pt_BR, not exact).
oS 12.1 64-bit KDE 4.9.1, nvidia driver 3.0.4, twinview mode, two monitors - one VGA (primary), one HDMI (TV).
There’s no various monitors tab/page, only the first three.
This page is helpful in adjusting multiple monitors behavior. Any way to get it back?
TIA
Note: both systems with equal PCI-E GT520 video cards.
That’s interesting - more questions than answers from me. I wonder if it is because you are using the proprietary driver. Isn’t the ‘nvidia-settings’ utility the best way to configure with the proprietary driver? Do you have the same (if any) xorg.conf in both OS installs? What does ‘xrandr’ report in each case?
Although you say it is helpful, I’ve found that multi-monitor configuration can be done entirely from the ‘Size and Orientation’ tool.
I’ll check and reply if applicable, but the issue is about the missing various monitors tab/page. AFAIK This does not depend on xorg.conf or driver in use - unless KDE4.9 does some kind of check and suppress it?
There are settings in the various monitors tab/page for setting fullscreen behavior (all monitors or just where the window is), window positioning, resilience (I think this is the term, not sure), etc. AFAIK this can’t be done - at least not easily - in xorg.conf.

There’s definitely a difference in how xrandr see the same device (nvidia GT520) in both machines. Either because of randr version or nvidia driver version.
Note: after the first post I changed the oS 12.1 outputs to DVI (primary display, connected to a VGA monitor through a DVI-VGA adapter) and HDMI. The various monitors tab/page is still missing.
As far as I understand to set multimonitors permanently you need a xorg.conf (or the corresponding sections in the appropriate files in xorg.conf.d/). This can be done with nvidia settings. Running as root, it creates a minimal xorg.conf that reflects the changes made - in this case, the multimonitor settings - that can be merged with the existing xorg.conf, if any, or simply saved, overwriting it. oS 12.1 uses the simple nvidia-settings-generated file, not merged. Not sure about oS 11.4, it’s been some time since I messed with it.

The xrandr command will only report what it can from the driver (RandR extensions), so it would be useful to compare with the same driver version installed. (I still think this is related to the nvidia driver.)
There is a KDE bug reported here:
