Configuration

Video Card

Easy Installation

Make sure Xorg is installed, and then install xf86-video-savage from the official repositories.

Then, edit your xorg.conf to reflect the following contents:

# xorg.conf -'man xorg.conf'
# see also 'man savage' for more detailed options
  ...
  Section "Device"
    Identifier "gfxcard"
    Driver "savage"
  EndSection
  
  Section "Screen"
    Identifier             "Screen0"  #Collapse Monitor and Device section to Screen section
    Device                 "gfxcard"
    Monitor                "Monitor0"
    DefaultDepth            16 
  EndSection
  ...

Advanced Installation

Thanks to Conor Behan for this post and User:mulesryan for figuring out this chipset.

The savage driver supports two types of hardware acceleration: XAA and EXA. Unfortunately, you can use DRI for SuperSavage only if you are using XAA. Since you want hardware 3D (for instance, opengl/d3d in wine) then this is probably important.

This means you must run xorg-server < 1.13, because starting in 1.13 XAA was removed.

Video Card Xorg Driver Mesa DRI Driver Packages needed for DRI
S3 SuperSavage IX xf86-video-savage savage-driAUR xf86-video-savage (<2.3.6-2) xorg-server (<1.13)§, xf86-input-evdev (<2.7.3-2), xf86-video-fbdev (<0.4.3-2), xf86-video-vesa (<2.3.2-2)

† - '--disable-shared-dricore' configure flag required (enabled by default in official repositories)
‡ - '--enable-dri' configure flag required
§ - '--enable-dri' configure flag required

If you've set up everything correctly, you should see this in /var/log/Xorg.0.log:

[ 63286.129] (II) SAVAGE(0): [DRI] installation complete
...
[ 63286.132] (II) SAVAGE(0): Direct rendering enabled
..

Are you using the versions of the packages specified? Are you using XAA acceleration? Did you compile with the configure flags specified?

Reason: This section was written a long time ago, and may not reflect the current state of Arch Linux (Discuss in Talk:IBM ThinkPad T23#)

Suspend and Hibernate

Works flawlessly. See Suspend to Disk. Also known to work with Pm-utils.

Sleepmode

An easy way is to use "suspend to swap" by appending

resume=/dev/sdx 

to the kernel line in /boot/grub/menu.lst

Sleepmode

Laptop Mode Tools

Works flawlessly. See Laptop Mode Tools.

CPU frequency scaling

Works as described in CPU Frequency Scaling.

Tp_smapi

See Tp_smapi

Hotkeys

They work better after loading the thinkpad_acpi module, to assign the generated keycodes to their supposed functions.

tpb

Install tpbAUR, available in the Arch User Repository.

tpb (for Thinkpad Buttons) adds an on-screen volume bar for the volume buttons, THINKPAD button assignment, on-screen messages for Thinklight, (on and off) and more.

NumLock

If not already working, this key may be configured by adding:

keycode 77 = Num_Lock 

to ~/.xmodmap.
