  Doesn't cover modem setup, could use a section on that. -- mulesryan (talk) 03:51, 8 Feb 2014 (CST) (Discuss in Talk:IBM ThinkPad T23#)

## 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-dri† | 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

##### Configuration

    xorg.conf

     ...
     Section "Extensions"
            Option "Composite" "Enable"
            Option "RENDER" "Enable"
     EndSection

     Section "Device"
            Identifier "gfxcard"
            Driver "savage"
            Option "hwcursor" "1"
            Option "DPMS" "on"
            Option "backingstore"
            Option "BusType" "AGP"
            Option "AGPMode" "4"
            Option "AGPSize" "16"
            Option "AccelMethod" "XAA"
            Option "DRI" "true"
            Option "BCIforXv" "true"
            Option "AGPforXv" "true"
     EndSection

     Section "DRI"
        Mode 0666
     EndSection
     ...

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
    ..
    [ 63286.233] (II) AIGLX: enabled GLX_SGI_make_current_read
    [ 63286.233] (II) AIGLX: Loaded and initialized savage
    [ 63286.233] (II) GLX: Initialized DRI GL provider for screen 0

##### Troubleshooting

    [  2864.984] (EE) AIGLX: reverting to software rendering
    [  2865.028] (II) AIGLX: Loaded and initialized swrast
    [  2865.028] (II) GLX: Initialized DRISWRAST GL provider for screen 0

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

### Power Management

This article or section is out of date.

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`.
