Installing Gentoo 2007.0 on a ThinkPad R61

Model

Lenovo Thinkpad R61 7743-Y1B

General

This installation instruction describes the steps after a Gentoo 2007.0 base installation. Please read the gentoo handbook for installation instructions

Working:

• Keyboard, UltraNav input (Touchpad and NavPoint)
• Drives
• X11 with nVidia including acceleration
• Network, wireless network and bluetooth
• Sound
• Suspend to RAM
• Suspend to Disk (Hibernate)
• ThinkLight
• PCMCIA
• ACPI (Battery, CPU Frequency, Fan, Temperature, ...)
• Fingerprint scanner (includes login and screen lock)
• Fn Key combinations
• Hot swapping of optical drive (UltraBay)
• HDD Acceleration Meter (can be used as an input device)
• Harddisk protection (kernel patched with this)

Not tested:

• Firewire (should work as it is recognized, no devices for testing)
• Express Card Slot (should work, no devices for testing)
• Docking Station (should work according to several sources, no devices for testing)

Graphics: NVIDIA Quadro NVS 140M

To install and configure the nVidia driver, just emerge nvidia-driver. Tested with nvidia-driver-100.14.19 up to 169.12, everything works fine, games run smooth.

Framebuffer works fine with vga=869 which will set the resolution to 1440x900. hwinfo --framebuffer displays all supported resolutions.

The brightness can be changed with newer nvidia drivers (>=169.04) Does not work with older drivers, only known workaround is to either use vesa / nv driver or to change the brightness on a vt.

Performance of the card depends heavy on powermizer and some nvidia settings.

In recent nvidia drivers, powermizer can be configured via `nvidia-settings`

#!/bin/sh
if [ -z "$1" ]
then
        echo "Powermizer control script."
        echo "2010 by Christian \"Fuchs\" Loosli."
        echo ""
        echo "usage: powermizer on | off"

else
        if [ $1 = "on" ]
        then
                nvidia-settings -a [gpu:0]/GPUPowerMizerMode=0
        fi
        if [ $1 = "off" ]
        then
                nvidia-settings -a [gpu:0]/GPUPowerMizerMode=1
        fi
fi
exit 0

This script turns powermizer on or off. You can use it together with acpi events or your power management to turn powermizer off as soon as your notebook is powered via AC.

Sound: AD1984

Did not work with older Versions of ALSA driver, works fine with ALSA 1.0.15 and should work with ALSA 1.0.14 as well. The in-kernel ALSA works since 2.6.23.

The mute button is hardwired and works, the volume up and volume down buttons work as well but you need to configure them first. You can use xmodmap to bind a key to them and then either bind a amixer command to them, or set them as hotkeys in your mixer application (kmix, gnome-mixer, ...) Please note that some mixer applications take the wrong mixer (the microphone) as the default, so you have to change the default / primary mixer in order to use things like kmilo.

Note: After muting you have to press a volume up or down button to unmute, and the mute status is not displayed in any mixer application.

Note for Kernel 2.6.24: Due to changes in thinkpad acpi the mute button does not longer work out of the box, but it does generate a key event. So you have to bind it to a script which mutes the headphone and speaker via amixer toggle <mixer>. This is a known problem to the thinkpad-acpi developers and probably will be resolved in the near future.

I recommend using alsa-drivers 1.0.16, as there is a new master mixer, which has mute capabilities to mute headphones and speaker. So you can either bind the key in a mixer application or you only have to use one amixer command.

Network: Intel E1000 NIC, IPW4965abgn WNIC, Bluetooth

The integrated e1000 LAN NIC works out of the box.

For wireless you have to unmask and emerge the iwlwifi package with the ipw4965 USEFlag enabled.

Don't forget that the interface (wlan0) has to be set as up (ifconfig wlan0 up) before scanning and associating works.

Bluetooth works out of the box with blueZ. You can disable / enable bluetooth via proc, with a script similar to this one:

<bash>

1. !/bin/sh

bluetooth=`head -n 1 /proc/acpi/ibm/bluetooth | awk '{print $2}'` case "$bluetooth" in

   disabled)
       echo "enable" > /proc/acpi/ibm/bluetooth

;;

   enabled)
       echo "disable" > /proc/acpi/ibm/bluetooth
       ;;

esac exit 0 </bash>

or directly with the proc interface. This script helps you to bind it to the Fn+F5 key combination.

Note that the hardware killswitch on the front works as well, but disables both bluetooth and WLAN

If you desperately want the wireless LED to work you can use this patch for a 2.6.24 kernel. Make sure to enable LED Triggers and LED groups in your kernel configuration, then there is a new option in the iwlwifi submenu. Works here, however, it doesn't blink on activity as it would with windows.

Ports: PCMCIA, USB, IEEE 1394 Firewire

PCMCIA port works out of the box, tested with an audigy pcmcia. I have no express slot cards available for testing.

The left hand usb ports generate an IRQ nobody cared error from time to time, Try to boot with irqpoll in your kernel line as suggested.

A BIOS Update might help as well, it is recommended to use the ThinkVantage Software Updater for windows for a BIOS Update. The error disappeared here and USB works fine.

Firewire is untested but should work, as the port is recognized and the module loaded.

Drives

The optical drive and hard drive work out of the box, with AHCI disabled or enabled in the BIOS.

If you run a dualboot system with windows <= 5.1 (XP) you probably want to disable AHCI anyway, at least until you have installed the ahci driver for Windows.

Input

TouchPad

Works out of the box here, with scrolling.

TouchPads are, as all the other input devices, not configured via xorg.conf anymore in xorg >= 1.6. You can either use hal policy files (deprecated as well), udev rules or synclient on a per user base.

I use

synclient HorizEdgeScroll=1 VertEdgeScroll=1 MinSpeed=0.25 MaxSpeed=0.42 AccelFactor=0.0010 VertTwoFingerScroll=1 HorizTwoFingerScroll=1 TapButton2=2 TapButton3=3 PalmDetect=1 PalmMinWidth=5 RTCornerButton=2 RBCornerButton=3

in my autostart, which activates two finger scrolling, multifinger tab and edge buttons.

The touchpad can be disabled via synclient when using the synaptics driver, a possible solution is this script:

<bash>

1. !/bin/sh

touchpad=`synclient -l | grep TouchpadOff | awk '{print $3}'` case "$touchpad" in

   1)
       synclient TouchpadOff=0;

echo "Touchpad Enabled" | osd_cat -d 1 -c cyan --font="-*-times-bold-r-*--34-240-*-*-p-*-*-*" -A center -p bottom ;;

   0)
       synclient TouchpadOff=1;

echo "Touchpad Disabled" | osd_cat -d 1 -c cyan --font="-*-times-bold-r-*--34-240-*-*-p-*-*-*" -A center -p bottom

   ;;

esac exit 0 </bash>

which needs xosd to display the current state. You can remove the "echo" line if you don't want the status being displayed or if you don't have xosd. You can make the script executable and map it to the fn+f8 button.

Trackpoint

Works out of the box as well, with no scrolling however. Can be configured via xorg.conf, I prefer using the middle button as mouse3.

Keyboard

Works out of the box, most of the Fn Keys work.

Hardwired: Mute, Thinklight, Brightness

Generates a keycode and can be configured: Volume Down, Volume Up, Fn+F2, Fn+F3, Fn+F4, Fn+F5, Fn+F7, Fn+F8, Fn+Arrows

Does not generate a key event: Fn+F9, Fn+F12, Fn+Space Those keys do produce an acpi event, so you can modifiy your acpi configuration to bind them to commands.

It is also possible to translate the acpi events to keyevents, have a look at the following configuration file:

My example default.sh file for the missing keys is here and there is a good, more complete howto here: Gentoo Wiki

Try whether echo "0xffffffff" > /proc/acpi/ibm/hotkey enables additional fn+fx keys to produce a key event instead of only an acpi event. Take a look at the ibm-acpi section as well to do this on module load.

Suspend

Suspend to RAM worked out of the box here, echo 3 > /proc/acpi/sleep puts the machine in suspend mode, opening it or pressing the power button wakes it up. Worked with nvidia driver and in X11. All devices came back without problems, wlan might have disconnected, but by using networkmanager, wicd or a good configuration it should reconnect after waking up. Works here with wicd.

Suspend to Disk is more complicated. Emerge a tux on ice kernel and try the configuration file linked at the end of this page. Disable intel-agp in the kernel. Make sure to load the nvidia module with NVreg_NvAGP=1 option.

This is my /etc/hibernate/common.conf file. Note that all options not mentioned here are commented (#)

Verbosity 0
LogFile /var/log/hibernate.log
LogVerbosity 3
HibernateVT 11
Distribution gentoo
# XDisplay :0

### clock
SaveClock restore-only

### hardware_tweaks
IbmAcpi yes
FullSpeedCPU yes

### modules
# UnloadBlacklistedModules yes
LoadModules auto

### xhacks
SwitchToTextMode yes
UseDummyXServer yes
# DummyXServerConfig xorg-dummy.conf

Note that the extra_pages_allowance might be too low. In current TuxOnIce versions the option to raise this value did not work anymore, that's why I put

echo 1000 > /sys/power/tuxonice/extra_pages_allowance

in my local.startup.

You can get the correct value by trying to suspend without it and reading /var/log/hibernate.log afterwards.

The machine can now be suspended to disk with the hibernate command.

Integrated Fingerprint Reader

Emerge the thinkfinger package, add a user with the tf-tool. Then you have to edit the /etc/pam.d/system-auth file by adding

auth sufficient pam_thinkfinger.so

between pam.unix and pam.env.

Read the Gentoo-Wiki to use it with xscreensaver, there is a good solution over there

Note: kdm has problems with thinkfinger auth and might crash. There are patches, but I didn't test them yet. gdm works fine here.

Hard Drive Active Protection

The integrated harddrive active protection acceleration meter can be used as a joystick or to get information about movements of your thinkpad.

Emerge the hdapsd (which includes a kernel module you have to load) which will generate a joystick and an event device.

It can be used for protecting your harddisk as well. You first need to patch your kernel with this patch and then rebuild it. Make sure to diable the kernel internal hdaps module, emerge hdapsd and tp_smapi with the hdaps flag enabled, rc-update add hdapsd boot and then reboot.

When shaking your notebook you should receive a message via dmesg that the hdd head has been parked. You can also use a frontend like khdaps.

Heads will only be parked with this method. However, in some situations and with some disk there will be a full spindown, which should be avoided as this might damage your harddisk when used too much.

On newer versions of xorg it might be possible that the accelerometer is seen as a mouse, which makes your pointer hop to the middle of the screen all the time. In order to solve this, you can create a udev rule:

/etc/udev/rules.d/99-hdaps.rules

SUBSYSTEM=="input", KERNEL=="event*", ATTRS{name}=="ThinkPad HDAPS accelerometer data", ENV{x11_driver}=""
SUBSYSTEM=="input", KERNEL=="event*", ATTRS{name}=="ThinkPad HDAPS joystick emulation", ENV{x11_driver}=""

which solves this problem.

Thinklight

The thinklight works out of the box with the Fn+PgUp key, but it can be controlled as well via the proc interface.

So you can write a nice script, which you can bind to events, such as incoming emails, to let the light flash.

A possible solution is this small script:

<bash>

1. !/bin/sh

if [ -z "$1" ] then echo "IBM ThinkLight Control script." echo "2007 by Christian \"Fuchs\" Loosli." echo "" echo "usage: lightctl on | off | toggle | blink" echo "blink takes two arguments: times and time" echo "defaults (5 times, 0.5 seconds) are used if not specified"

else if [ $1 = "on" ] then

   	       echo on > /proc/acpi/ibm/light

fi if [ $1 = "off" ] then

  	       echo off > /proc/acpi/ibm/light

fi

       if [ $1 = "toggle" ]

then status=`cat /proc/acpi/ibm/light | grep status | awk '{print $2}'`

if [ $status = "on" ] then echo off > /proc/acpi/ibm/light else echo on > /proc/acpi/ibm/light fi fi

if [ $1 = "blink" ] then

times=$2 time=$3

if [ -z "$2" ] then times=4 fi

if [ -z "$3" ] then time=0.5 fi

   	        for i in `seq 1 $times`;
   	        do
   		        $0 toggle;
                       sleep $time;
                       $0 toggle;
                       sleep $time
   	        done    

fi fi exit 0

</bash> which can be called to let the light blink or switch it off or on. The blink part is nice for setting to events such as incoming messages or emails.

There is a version slightly modified by a friend of mine here which has a lockfile and is slightly optimized.

(note: the thinklight is a LED, so it should not care on how fast and often you let it blink. But I am not responsible if this script damages your thinklight. Use at own risk.

Power saving

First of all, turn off all things you are not using, most of all bluetooth and W-LAN. You can use the killswitch on the front, it works out of the box.

You can use the application powertop by Intel to look for processes which prevent the CPU from longer sleep states.

It also gives you some recommendations on services to turn off. Do _not_ turn off the optical drive polling by HAL.

Dimming the display also saves lots of power.

Since 2.6.24 dynticks are available for x86_64.

I managed to get powerconsumption down to:

• 20W running normal with compiz, wlan & bluetooth enabled

• 16.7W running a normal windowmanager

• 14.5W with bluetooth and wlan disabled (killswitch)

I had between 195 and 600 wakeups per second.

Also hda-intel and s-ata power consumption was reduced in 2.6.24

You can achieve about 2 - 3 hours of working time (no compiling or other heavy CPU / GPU usage applications) with the standard battery like this.

ibm-acpi

I have ibm-acpi configured as a module in my kernel, as I load it with

options thinkpad_acpi hotkey=enable,0xffffffff brightness_enable=1 fan_control=1

to enable brightness controll via /proc/acpi/ibm on newer kernels and fan control. The hotkey=enable,<mask> option is used instead of writing to /proc/acpi/ibm/hotkey.

The default file permissions in /proc/acpi/ibm/* do not grant write access for users. I created the group "ibm", added my users to it and now I chown root:ibm and chmod 0774 the files in /proc/acpi/ibm/ on startup. If you don't want to do this you might use sudo sh -c "echo "foo" > /proc/acpi/ibm/whatever", but you need to install sudo and modify your sudoers file.

Configuration Files

xorg.conf

Note that I use the XFont Server, you might have to change the font path.

You also might want to change the keyboard layout.

' Note: in this configuration here nvidia wont read out sane refresh and sync values out of your flat panel.

In this configuration the modes given don't affect the modes available and you will have all screen resolutions available, but it might fail on other display devices.

If you get a blank screen or strange refresh values, add # in front of the marked line to disable this behaviour, so the nvidia driver will still read out sane resolutions.

xmodmap

Note: you have to xmodmap /path/to/file this file in your autostart. You might have different keycodes, use the application xev to display them. It is highly recommended to use the XF86foobar buttons, as some applications will be preconfigured to them. If you want to map them by yourself use Fxx, while xx > 12.

default.sh (acpid)

This is my slightly modified default.sh file to handle ibm hotbutton events. Of course you can add the other buttons as well, however, as they produce key events there are easier ways for configuring the actions. However, an acpi solution is window manager / X independent.

You can read out the key events, as they might differ on your model, with the acpi_listen application.

<bash>

1. !/bin/sh
2. /etc/acpi/default.sh

set $*

group=${1%%/*} action=${1#*/} device=$2 id=$3 value=$4

if [ "$group" = "ibm" ]; then key="$2"\ "$3"\ "$4" fi

log_unhandled() { logger "ACPI event unhandled: $*" }

case "$group" in button) case "$action" in power) /sbin/init 0 ;;

*) log_unhandled $*

                               ;;

esac ;;

ibm) case "$action" in hotkey) case "$key" in "HKEY 00000080 00001008") /usr/bin/acpi_fakekey 220 ;; "HKEY 00000080 00001009") /usr/bin/acpi_fakekey 221 ;; "HKEY 00000080 00001014") /usr/bin/acpi_fakekey 222 ;; *) logger "acpid: $group/$action $key is not defined" ;;

esac ;; *)

                       ;;	

esac ;;

*) log_unhandled $*

               ;;

esac </bash>

Note that I use acpi_fakekey to translate acpi to key events.

ACPI Fakekey

With this nice app you can translate acpi events into key codes.

I borrowed it from gentoos acpi-support, which borrowed it from Ubuntu people.

You can it out of the sunrise overlay, I recommend only getting the acpi-fakekey.c file and compile it.

For the lazy guys:

There is an explanation and the source code, which I wont copy and paste here, on this page:

Gentoo Wiki on Hotkeys

I use this in the file above to generate keycodes for Fn+F8, Fn+F9 and Fn+Space.

Kernel configuration

2.6.24 TOI Kernel config

Please note: this configuration works for my setup, it might not for yours.

I use ext3 as my file system, make sure to compile in the support for the file system you are using, at least for the root partition.

I also use external ALSA drivers. But I use lots of stuff you probably will never use, such as several gamepads, acl support for ext3, some ipv4 / ipv6 filters ... You might want to remove those.

This is the configuration for a 2.6.24 Kernel, it differs a little bit from the configuration of earlier kernels.

Unstable Kernels and updates

2.6.27

Recently, 2.6.27 gentoo hit portage. There are several imporant changes.

My kernel config is here, the hdaps patch is here. Please note that you need a recent hdpasd to work with this new version.

Intels Wifi module is now split up and named iwlagn and iwlcore.

Suspend and Hibernate work without Tux on Ice kernels. (Just be patient with hibernate, you'll get a black screen for a while before it comes back up)

You also need a recent nvidia driver to work with the new kernel.
