Apparently you are missing the xf86-video-sis video driver. If the Leap system is already installed and able to boot one way or another, you can boot adding the “nomodeset” option to the boot command line:
when at the boot prompt, press “E”, search for the “linux” line and append “nomodeset”, then press F10 to boot.
Log in, then in a terminal run:
su -
<root password>
zypper in xf86-video-sis
and reboot. You should have now a choice of resolutions supported by your graphic adapter.
