Sax2 trouble; please help me get back the 1024x768 resolution!


Originally I had a screen resolution of 1024x768, the screen just using the whole visible display area, tiny little kde logo and icons and menus which I liked much.
Then I noticed that the screen aspect ratio is screwed up when I change video mode to 640x480, i.e. the screen stretched much over the visible display area vertically, while it was squeezed horisontally (large black stripes at the left and right sides of the screen).
I wanted to fix this and I screwed up everything with Sax2:

Now the max. screen resolution that I have is 800x600; I have large kde logo on kde startup, large icons and menus in all applications, and I have 1cm-wide black stripes at the left and right side of the screen.
When I try to change video mode with CTRL ALT + or CTRL ALT -, I can only switch between 800x600 and 640x480. The screen resolution 1024x768 seems to be no longer available.
I may be wrong, but it all seems for me as if my system would insist on a specific and fairly high vertical frequency (106Hz), which it can only "offer" at resolutions 800x600 and 640x480, so it only lets me use these resolutions. Is it possible that this is the reason?

Here are my present sax2 settings, which I just cannot change so that I get back the 1024x768 resolution:
Monitor: Philips 107E (17INCH/CM2600); frequencies: 30-70kHz horisontal, 50-120Hz vertical; experts settings: modeline algorithm: CheckDesktopGeometry, screen size in mm: X:0, Y:0; DPMS enabled
Graphic card: (0) Nvidia GeForce2MX 100/200 nvidia
Colours/Resolution: (0) 1024x768 16bit (65536)
Properties of presently configured workspaces:
workspace0/colours: colour depth: 65536 [16 bit]
(Selected) Resolutions at colour depth 65536 (16 bit): 1024x768, 800x600, 640x480
Startup parameters of graphical desktop: 1024x768
Virtual resolution: not set
3D acceleration: enabled
Geometry: (0) 800x600 69kHz, 108Hz,72MHz

Among the above settings the Geometry of 800x600 seems to determine my screen resolution. The problem is that I do not know how to change it to 1024x768.

Could you help me?

P.S:
I almost forgot about my original problem: i.e. how to configure your system so that you have a correctly sized and positioned screen in all video modes you select (or at least in those with resolutions 1024x768, 800x600 and 640x480)? Is it at all possible?

Take a look at the amount of video memory that you have configured. Your problem may be that the video memory is set to too small.

It was not the video memory, because I had not mess with that before.
.
However, I realized one thing I did not notice before: all my changes trying to correct the settings were lost when I exited sax2!
When I noticed this, I thought I might try to use a trick that works in Windows: to restart the machine. (Naturally I had tried logouts-logins before to restart the X server, but it did not help).

After reboot, I started Sax2; and took the occasion to select an other Philips monitor type that seems to slightly better fit my present monitor type; and in the moment sax offered me the 1024x768 resolution. (Naturally I tried to set that monitor type before the reboot, but that setting has always been lost just like other settings, until I finally rebooted the machine)
I configured the 1024x768 resolution, and after a new reboot, my system was as before.

I do not know if it was only the reboot that cured the problem or the reboot together with the selection of a new monitor triggered something, but it does not matter now.

Thank you for your attention!
