I installed FreeBSD 4.10 on my computer, did all of the packages things, then I go config the XFree86, then i save, then i exit the stand sysinstall program.
I type X, but when it goes in X, I only see my mouse, and the background is nothing, white and gray.

What do you think that I misconfigured?

SiS 630 as video card
Monitor 1280x768 at 70 hertz frequency

My chipset is SiS.

What could be my problem? I even tryed to install Slackware 10, but it does the SAME thing (even thought i didnt know how to manually config the X under bash at this time)

Alot depends on the X11 windows version your are using. The sis 630 was not supported until Xfree 4.3 or Xorg 6.7.

I am using Slackware 10 on a ECS desknote with Xorg and have no problems other than 3D acceleration is slow.

For more than you would ever want to know about SIS video chips see:

What version of XFree86 is on there? Do pkg_info | grep XFree86 to get a list of the X-related packages installed. If the packages loaded from the CD, you should have XFree86-4.3.0,1 installed, and as I understand it, your graphics chipset should be supported, as evidenced by the moire background + mouse cursor.

What does your X log file look like? (/var/log/Xfree86.0.log) What does your X config look like? (/etc/X11/XF86Config) Is there a .xinitrc file in your home directory telling X to load your desktop?

Distrowatch is a good place to see what version of Xwindows you are using

Since you have Xfree 4.3 it shoulc work so it looks like the problem is with the config file.

The moniter resolutions look a little odd. Standard is 1280x1024 or 1024x768

Try running xf86config.

Here are the Slackware instructions (should be the same in FreeBSD4.10) since xf86config is an Xfree utility
