# IBM ThinkPad T61

From ArchWiki

## Wireless

### Intel 4965 WiFi

If you have the Intel 4965 NIC, simply install iwlwifi-4965-ucode, run depmod, and run "modprobe iwl4965" to activate. For wpa_supplicant, use the WEXT driver, not the deprecated ipw200.

The latest Kismet runs well on the iwl4965, but occasionally has problems changing the mode back to Managed from Monitor.

If you have the AR5212 802.11abg NIC all you need is madwifi. Install it, and the kernel module is ath_pci.

## Xorg

### Synaptic

Works great with the settings provided in the Pacman output

## Graphics

### Nvidia

Driver works great, even with composite enabled.

### Intel

Don't have it, so cannot say.

    xf86-video-intel from testing should support the Intel video. I haven't tried it yet, but I'll report back when I do.

## Power Management

### ACPI

Install acpi, acpid. Add acpid to the daemons list. Load module thinkpad_acpi. You might have to blacklist asus_acpi/toshiba_acpi, it doesn't hurt anyway. It should work, and is able to provide accurate information to such programs as Conky and GKrellm, as well as the GNOME battery monitor.

### SpeedStep

The regular way works fine.

### Suspend/Resume

Suspend/Resume technically worked out of the box for me, however resuming took about 2+ minutes, while my screen stayed off and my speaker beeped 2-3 times. Sometimes it hung up too. These changes seemed to have worked for me and where found here. Remember to remove the boot parameters acpi_sleep=s3_bios or acpi_sleep=s3_mode if you have them, they do not seem to be needed anymore and may cause the system to crash on resume.

## Thinkvantage Rescue and Recovery

The Rescue and Recovery partition can be /dev/sda1 or /dev/sda2, not sure which this depends on

The following GRUB entry did work on my T61

         title ThinkPad Rescue and Recovery
         rootnoverify    (hd0,0)
         chainloader     +1

## Fingerprint Reader

Install Thinkfinger

    pacman -S thinkfinger

Update PAM configuration to accept thinkfinger as auth input. See Thinkfinger Configuration

## Sound

The module is snd-hda-intel. It works, albeit with several unresolved quirks. The mute button works partially out of the box (it can mute but not unmute.) To unmute, press either the volume up or volume down buttons. However, one workaround is enabling the volume up/down buttons as Keyboard shortcuts in your Desktop environment.

--Edit: Since Kernel 2.6.25 the mute/unmute function works out of the box. Now it unmutes also!

--Edit: To enable sound you must unmute the internal speaker channel, and turn down or mute the microphone channels, otherwise you will get nothing but a squeaking sound from the speaker.

--Edit: On my t61 sounds did not work till I added "snd-hda-codec-analog" to the modules, recompiled the modules (sudo mkinitcpio -p linux) and restarted.

## HDAPS

See HDAPS.

## Built-in Camera

Install the linux-uvc-svn on community, version 211-1 is workable

## Multimedia Keys

Use pacman to install xmodmap (xmodmap is included in the xorg-server-utils package), then create a text file ~/.Xmodmap and put this in it:

these are for the pager buttons

     keycode 234 = XF86Back
     keycode 233 = XF86Forward

these are the music changing buttons:

     keycode 144 = XF86AudioPrev
     keycode 164 = XF86AudioStop
     keycode 162 = XF86AudioPlay
     keycode 153 = XF86AudioNext

this is for the silver volume buttons:

     keycode 160 = XF86AudioMute
     keycode 174 = XF86AudioLowerVolume
     keycode 176 = XF86AudioRaiseVolume

based on which Desktop environment you are in you will have to edit your hotkeys to get it working, if you are in a WM that doesn't provide this functionality, try installing xbindkeys

### XFCE

Assuming you are using alsa, open the XFCE keyboard configuragtion GUI (XFCE Menu > Settings > Keyboard) and add the following to the 'Application Shortcuts' tab. When prompted press the appropriate multimedia key.

Mute

     amixer -q set Master toggle

Volume Down

     amixer -q set PCM 2- unmute

Volume Up

     amixer -q set PCM 2+ unmute

The previous two will adjust the PCM value by 2, if you desire you can change this number.
