SiS

This guide is about SiS's onboard graphic chips.

Introduction

There is quite poor Linux support for SiS graphics. To name it, 3D is not supported and the existing 2D driver - although powerful and works - is from 2005 and is no longer active developed.

Kernel Setup

Device Drivers  --->
    Graphics support  --->
        <*> /dev/agpgart (AGP Support)  --->
            <*>   SiS chipset support

Xorg Setup

Add this line to your /etc/make.conf so that you will include only one graphics driver into Xorg server:

 VIDEO_CARDS="sis"
 

Install Xorg using emerge xorg-x11 or update your system by running emerge -uDNva xorg-x11, but this may update parts of your system in addition to updating Xorg.

The good thing: you need no /etc/X11/xorg.conf for a basic setup.

Advanced Topics

For all available options, see the driver's homepage.

Control GUI

sisctrl is a tool for setting/changing some driver parameters during runtime on a 300, 315, 330 or 340 series or XGI Volari based machine/card or a SiS/Net2280 USB/VGA dongle. It requires the gtk+ 2.4 (or later) library. SiSCtrl will not work on the old series!

To install sisctrl, run emerge --ask sisctrl and edit your /etc/X11/xorg.conf:

 Section "Device"
        Identifier      "Generic VGA"
        Driver          "sis"
        Option          "EnableSiSCtrl" "yes"
 EndSection
