After searching on google, I finally got the driver to change the VGA resolution on Ubuntu 9:10 SIS, is to install the SIS file, there are 2 files that must be installed, is the xorg.conf and the control of SIS. First, download the file, then install the SIS file and install the control file.
Installation same as Ubuntu 9.04, which is double-click on the file .deb
Driver files can be downloaded below:
NB: Unable to run compiz, because this 2D SIS driver.

You help me…
