Graphics: NVIDIA Quadro NVS 3100M (GT218)
To install and configure the nVidia driver, just emerge nvidia-drivers. You might be interested in the ~arch masked drivers.
Framebuffer works fine with vga=0x361. hwinfo --framebuffer displays all supported resolutions.
The brightness control needs a workaround. Add
Option "RegistryDwords" "EnableBrightnessControl=1"
to your xorg.conf
Performance of the card depends heavy on powermizer and some nvidia settings.
In recent nvidia drivers, powermizer can be configured via `nvidia-settings`
<bash>
- !/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 </bash>
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
Works out of the box. The microphone might has to be unmuted via alsamixer. If you are using pulse audio, check pavucontrol as well.
The mute button and 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 hdmi output) as the default, so you have to change the default / primary mixer.
Network: Intel E1000 NIC, WiFi Link 6000 Series WNIC, Bluetooth
The integrated e1000 LAN NIC works out of the box.
For wireless you have to emerge the net-wireless/iwl6000-ucode package. You have to enable iwlwifi / iwlagn in your kernel configuration.
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>
#!/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 a key combination.
Note that the hardware killswitch on the front works as well, but disables both bluetooth and WLAN
In recent versions of the driver, several 5 GHz networks create a lot of disconnects. You can try to set
options iwlagn 11n_disable=1
in /etc/modprobe.d/iwlagn.conf as a temporary solution while Intel is working on a fix.
Ports: USB, HDMI, IEEE 1394 Firewire
USB works out of the box.
Firewire is untested but should work, as the port is recognized and the module loaded.
HDMI is untested, but as it is recognized (including the alsa audio device) it should work.
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 might want to disable AHCI anyway, at least until you have installed the ahci driver for Windows.
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 and app-laptop/tp_smapi with the hdaps USE-Flag enabled, which will generate a joystick and an event device.
It can be used for protecting your harddisk as well. 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.
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.
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 the xorg.conf.d directory, 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>
- !/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: 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+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
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 works out of the box as well.
Integrated Fingerprint Reader
Not tested yet
Integrated Webcam
The Camera seems to be a Chicony Electronics Co., Ltd. device, with
Vendor ID: 0x17ef Product ID: 0x480f
You have to enable: Video capture adapters ---> V4L USB devices ---> USB Video Class (UVC) in the kernel, then the camera will work out of the box (tested with Kopete)
Integrated Card reader
The card reader is a
SD Host controller: Ricoh Co Ltd Device e822 (rev 01)
You can enable the sd/sdhci drivers in the Kernel in order to get it to work.
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>
- !/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.
(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.
You can achieve about 4 - 6 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 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.
