Higher resolution

Im using Kubunto.

I want to use 1600x1200 as resolution in KDE but the highest one I can choose is 1280x1024. How do I fix that?

I also want run 2 monitors on one Kubunto machine, (1600x1200 and 1280x1024).
My graphics card is a Geforce 4600.

First of all: does your monitor support 1600x1200?
If so, edit /etc/X11/XF86Config-4 (or possibkl xorg.conf)
Look for Section "Screen"
Here's mine:
Section "Screen"
  Identifier "Screen0"
  Device "Card0"
  Monitor "Monitor0"
  DefaultColorDepth 16
  SubSection "Display"
  Depth 15
  Modes "1024x768"
  SubSection "Display"
  Depth 16
  Modes "1280x1024" "1024x768"
  SubSection "Display"
  Depth 24
  Modes "1024x768"
  SubSection "Display"
  Depth 32
  Modes "1024x768"
Choose your colour depth, and change Modes to what you want.

Second question: You need nVidias driver to do that, I don't know if they're included in Kubuntu.
Look for Section "Device" in same file as above; again, here's mine:
  Option "NoLogo" "false"
  Option "IgnoreEdid" "true" # needs to be true for some nvidia cards
  Identifier  "Card0"
  Driver "i810"
  BoardName "unknown"
 #BusID  "PCI:1:0:0"
If Driver is "nvidia" then you have the correct one.
If it's "nv", you could try changing to "nvidia" and restart X. If you don't have nvidia-driver installed, X won't startup.
If so, go to Nvidias homepage, download driver and follow instructions. (This is very easily done.)
Then add to Section Screen(we're still talking bout same file, XF86Config-4):
(And this time an example from my nVidia-computer: )
 # Only the official NVIDIA driver supports twinview
  # these setting are an example
  Option "TwinView" "true"
  Option "SecondMonitorVendorName" "unknown"
  Option "SecondMonitorModelName" "unknown"
  Option "SecondMonitorHorizSync" "30-82"
  Option "SecondMonitorVertRefresh" "50-75"
  Option "MetaModes" "1024x768, 1024x768; 800x600, 800x600; 640x480, 640x480"
  Option "TwinViewOrientation" "RightOf"
  Option "ConnectedMonitor" "crt,crt"
You will have to check HorizSync and VertRefresh, don't put them too high or you might fry your monitor!
That line w "MetaModes":
I think you should use
Option "MetaModes" "1600x1200, 1280x1024@1280x1024" (If you want second monitor fixed size)
Option "MetaModes" "1600x1200, 1280x1024" (If you want second monitor floating desktop)
And finally, Option "ConnectedMonitor" "crt,crt" change it to what you have:
crt=old type monitor
dfp= digital flat panel

Higher res:
To check in xorg.conf>>
There's a section containing the lines vertrefresh and horizsync. They have to reflect the capabilities of your monitor.
Then there's a line describing the possible resolutions; the required resolution should be in there as well.

Dual head:
I don't know
