twinview first and second monitor switch

I have a little (but significant) prolem with twinview...
i configured my xorg.conf for using the two monitors at the resolution i wanted them. the thing is that i want my laptop lcd screen to be the *first* monitor, while the external crt monitor should be the *second*, so that the actual desktop with taskbar, icons and stuff is on my laptop, while the external monitor is the "extansion" (now it is the opposite).

is there a way i can tell the system which monitor is the first and wich the second?
i have an nvidia card with nvidia drivers installed... it's quite recent, but i can't remember the exact model name.

btw, another problem i have since i configured the twinview is that the scrollwheel doesn't work anymore... any idea?

here is my xorg.conf:

I was using nvidia's twinview to get my dual monitors out. It worked just fine, I could drag windows between the two and everything, except that the main monitor was on the wrong screen, the panel always showed up on the wrong side.

After working on it for several hours, I finally gave up and tried simply to drag the panel across from my secondary monitor onto my main monitor. VOILA! It worked! And all this time I thought there was something wrong with xorg.conf!

Anyway, hopefully that's all you need to do. If not, good luck.

yes i had solved the problem this way! the only thing is that the icons are still placed in the wrong screen, and i have to drag them every time... no big deal anyway!

i don't get what happened to the scroll wheel though... i'll just play around with xorg.conf a little bit...

I have the same problem with twinview setting up the monitors opposite of what I would like them. I would hope there is a better way to do this. Because when I try to run a full screen opengl application, it will still try to output to the wrong monitor.

From nvidia-bug-report.log
Code:
(**) NVIDIA(0): Option "HWcursor" "true"
(**) NVIDIA(0): Option "ConnectedMonitor" "CRT-1, CRT-0"
(**) NVIDIA(0): Option "TwinView" "True"
(**) NVIDIA(0): Option "TwinViewOrientation" "LeftOf"
(**) NVIDIA(0): Option "SecondMonitorHorizSync" "31.5 - 67.0"
(**) NVIDIA(0): Option "SecondMonitorVertRefresh" "50.0 - 75.0"
(**) NVIDIA(0): Option "MetaModes" "1280x1024, 1280x1024; NULL, 1280x1024;"
(**) NVIDIA(0): ConnectedMonitor string: "CRT-1, CRT-0"
(**) NVIDIA(0): TwinView enabled
(--) NVIDIA(0): Linear framebuffer at 0xD8000000
(--) NVIDIA(0): MMIO registers at 0xE0000000
(II) NVIDIA(0): NVIDIA GPU detected as: GeForce 6800
(--) NVIDIA(0): VideoBIOS: 05.40.02.12.71
(--) NVIDIA(0): Interlaced video modes are supported on this GPU
(II) NVIDIA(0): Detected AGP rate: 8X
(--) NVIDIA(0): VideoRAM: 131072 kBytes
(II) NVIDIA(0): Using ConnectedMonitor string "CRT-0, CRT-1"
I even tried to specify using CRT-1, CRT-0 for my monitor setup and for some reason it still reverts to CRT-0, CRT-1? I'm at a loss....
