I'm sorry but I don't really understand what you mean by virtual screen. Do you mean that the you have for example a virtual 1280x1024 screen displayed on a 1024x786 actual screen?

If that is what you mean, then post your /etc/X11/XF86Config-4 file.

Thank you for your reply.
Iam trying to use 800x600 Res and when ilog in ihave a desk top larger than the screen. Hereis the config.

I just realized that since upgrading to lm 10, my /etc/X11/XF86Config-4 file also uses Virtual entries in the display entries. On mine however, the Monitor model I selected was for the same resolution as the display I use.

Section "Monitor"
Identifier "monitor1"
VendorName "Generic"
ModelName "Flat Panel 1280x1024"
HorizSync 31.5-67
VertRefresh 50-75

Subsection "Display"

Virtual 1280 1024
EndSubsection

Otherwise, your XF86Config-4 looks like mine.
If you had chosen a monitor option that could only display 800x600, and a virtual screen as 1026x786, then I would expect to see what you are seeing. But your config indicates the opposite.
Perhaps perusing the /var/log/less XFree86.0.log might help.
Look for lines like:
(**) NVIDIA(0): Validated modes for display device DFP-0:
(**) NVIDIA(0): Default mode "1280x1024": 108.0 MHz, 64.0 kHz, 60.0 Hz
(**) NVIDIA(0): Default mode "1280x960": 108.0 MHz, 60.0 kHz, 60.0 Hz
(**) NVIDIA(0): Default mode "1152x864": 108.0 MHz, 67.5 kHz, 75.0 Hz
(**) NVIDIA(0): Default mode "1024x768": 78.8 MHz, 60.1 kHz, 75.1 Hz
(**) NVIDIA(0): Default mode "1024x768": 75.0 MHz, 56.5 kHz, 70.1 Hz
(**) NVIDIA(0): Default mode "1024x768": 65.0 MHz, 48.4 kHz, 60.0 Hz
(**) NVIDIA(0): Default mode "832x624": 57.3 MHz, 49.7 kHz, 74.6 Hz
(**) NVIDIA(0): Default mode "800x600": 49.5 MHz, 46.9 kHz, 75.0 Hz
(**) NVIDIA(0): Default mode "800x600": 50.0 MHz, 48.1 kHz, 72.2 Hz
(**) NVIDIA(0): Default mode "800x600": 40.0 MHz, 37.9 kHz, 60.3 Hz
(**) NVIDIA(0): Default mode "800x600": 36.0 MHz, 35.2 kHz, 56.2 Hz

But before you go any further, Why try 800x600 resolution? Do you have a 13" crt?
If not, 1024x768 will probably be the minimum size to use.

Thanks for reply.
Tried reconfiguring Monitor to 800 x 600 also 1024x768 still virtual at both resolution . The Monitor is a 14 inch crt . Checked var log as sujjested and found this.

WW) RADEON(0): monitor1: Using default hsync range of 28.00-33.00kHz

(II) RADEON(0): Not using default mode "640x480" (hsync out of range)
(II) RADEON(0): Not using default mode "320x240" (hsync out of range)

The Ranges specified in the XF86Config-4 File are as per Monitor Manual This varlog is for original config as per 2nd Post
maybe i need to change this
