This page describes how to get Silicon Integrated Systems (SiS) chipset graphical adapters working on Arch Linux:

Packages

You will need main xf86-video-sis with driver and it's good idea to install sisctrl (gui tool for setting video modes). Some cards not supported by sis driver package can work with xf86-video-sisusb and xf86-video-sisimedia. You can also check xf86-video-sis671AUR from AUR.

lspci

Output of lspci should look like this (depends on present model):

01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 661/741/760 PCI/AGP or 662/761Gx PCIE VGA Display Adapter

Modules & rc.conf

There are couple of modules related to SiS video cards:

$ modprobe -l | grep -i sis
/lib/modules/2.6.28-ARCH/kernel/drivers/usb/misc/sisusbvga/sisusbvga.ko
/lib/modules/2.6.28-ARCH/kernel/drivers/video/sis/sisfb.ko
/lib/modules/2.6.28-ARCH/kernel/drivers/char/agp/sis-agp.ko
/lib/modules/2.6.28-ARCH/kernel/drivers/gpu/drm/sis/sis.ko

You will probably need to load only sisfb (it will probably load the other sis modules as required by your hardware) as first and then the other modules. So the beginning of MODULES array in your /etc/rc.conf should look like this:

MODULES=( sisfb ... )

xorg.conf

Here are few most important sections from /etc/X11/xorg.conf

  1. Load some modules:
Section "Module"
  Load  "dbe"
  Load  "i2c"
  Load  "bitmap"
  Load  "ddc"
  Load  "dri"
  Load  "extmod"
  Load  "freetype"
  Load  "glx"
  Load  "int10"
  Load  "vbe"
EndSection
  1. Device specification:
Section "Device"
  Identifier "Card0"
  Driver "sis"
  Card        "** SiS (generic)     [sis]"
  BusID "PCI:1:0:0"

  Option "UseFBDev" "true"
  Option "EnableSisCtrl" "yes"
  Option "ForceCRT1Type" "LCD"
  Option "ForceCRT2Type" "NONE"
  #Option "CRT2Detection" "true" #For me this worked better than forceing the detection. If you use this comment out the two Force lines above this.
  Option "CRT1Gamma" "on"
  Option "CRT2Gamma" "on"
  Option "Brightness" "0.000 0.000 0.000"
  Option "Contrast" "0.000 0.000 0.000"
  Option "CRT1Saturation" "0"
  Option "XvOnCRT2" "yes"
  Option "XvDefaultContrast" "2"
  Option "XvDefaultBrightness" "10"
  Option "XvDefaultHue" "0"
  Option "XvDefaultSaturation" "0"
  Option "XvDefaultDisableGfxLR" "no"
  Option "XvGamma" "off"
EndSection
  1. Enable Direct Rendering:
Section "DRI"
  Mode         0666
EndSection

Enable SSE

enable or force the SSE use in SiS Card

Add

 Option "UseSSE" "yes"

to Device section

SiS 671 card

Add

 Option "UseTiming1366" "yes"

to Device section.

Dual head configuration

You need 2 device sections to enable dualhead mode. Sis specific options should be placed into master head device section.
