SiS
This page describes how to get Silicon Integrated Systems (SiS) chipset graphical adapters working on Arch Linux:
Contents
Packages
You will need main xf86-video-sisAUR 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-sisimediaAUR.
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
There are couple of kernel modules related to SiS video cards:
$ lsmod | grep sis | sed -re 's#^([a-zA-Z0-9_-]*) *.*#\1#g' | xargs modinfo | grep 'filename:' ... filename: /usr/lib/modules/kernel-version/kernel/drivers/char/agp/sis-agp.ko.gz filename: /usr/lib/modules/kernel-version/kernel/drivers/char/agp/agpgart.ko.gz ...
where kernel-version
is the kernel version currently installed on your system. For example kernel 3.7.1.1
You will probably need to load only the sis-agp kernel module.
xorg.conf
Here are few most important sections from /etc/X11/xorg.conf
- 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
- 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
- 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.
