Linux (Debian Squeeze) on Thinkpad T500

I recently got myself a Lenovo Thinkpad T500 (2055V1X) . I chose this older model over the T510 and such, because I prefer a screen resolution of 1680×1050 over a crippled 1600×900 or worse. I write and read a lot of code so I need vertical space on the display and I’d definitely miss the 150pixels additional vertical space my old Laptop (Samsung X20 with a resolution of 1400×1050) has.

However, I shrunk the Windows 7 partition (I didn’t want to dump Windows entirely) and installed Debian Squeeze (AMD64) in the resulting free space. I’m very pleased how painless everything was, almost all hardware ran out of the box, but I’ll document some interesting stuff (how to shrink windows partition without breaking it, how to make special keys work and display information on Linux, how to make the touchpad and trackpoint behave the way I want, …) anyway.

Shrinking Windows

There were three partitions: a small one (about 1,2GB) called SYSTEM_DRV, which seems to be a Win7 boot partition (since when does Windows have a seperate partition for that?), on the second one was the Windows installation (this is the one I shrunk) and the third one of about 9,8GB that contained Lenovo recovery stuff (double-clicking it lets you burn that stuff onto three DVDs – which may make sense because Lenovo doesn’t ship any DVDs/CDs with the Thinkpad so if your harddrive fails you’re fscked).
I defragmentated the system partition and then tried to shrink it with Windows onboard-tools (here is a description), but it was not satisfactory: even though “only” 24GB were used by Windows and all that preinstalled crap, I could only shrink the partition to a size of 190GB, if I recall correctly. The reason was some unmovable system file or something like that.
I wanted to shrink it to 100GB, so I used the Linux tool GParted from the grml Live-CD to do the job, which it did without any problems: On the next boot Windows did a file system check or repair or something and kept on functioning without any complaints.


Before installing Debian I got the Squeeze Beta2 netinstall ISO from and burned it to a CDRW.
Update: Squeeze is now stable, use the netinstall ISO from

My T500 has got two display adapters: An Intel GMA X4500 and a AMD Mobility Radeon HD 3650. Only very recent versions of the Linux kernel (2.6.34 onwards as far as I know) support switching between them at runtime (but still X needs to be restarted) – Squeeze is still at 2.6.32, so that won’t work without a custom kernel. See the ThinkWiki for further information.
One can still switch the adapters in the BIOS (press F1 after powering on the Thinkpad). Because I don’t need much 3D power at the moment and prefer longer battery life, a better driver and a cooler laptop I chose to use the Intel Chip (“Discrete Graphics”). Because of that I won’t describe how to make the Radeon work, but it shouldn’t be too painful (either use the default free driver or install the proprietary fglrx).
My settings in the BIOS (Config -> Display) look like this:

Default Primary Video Device  [Internal]
Boot Display Device           [Thinkpad LCD]
Graphics Device               [Integrated Display]
OS Detection for Switchable Graphics 

To install Debian you want to have Ethernet (wired LAN) ready for Internet-access, because the wireless chip in the T500 (at least in mine) needs proprietary firmware from Intel that Debian doesn’t include by default.
However, if you’ve only got wireless Internet you can supply the firmware from a USB-stick, the Debian installer will prompt for that.
Update: See the debian Wiki for more information, including links to netinstall-ISOs that include firmware.

Installing Debian

Just insert the CD, boot, follow the instructions (I won’t describe that in detail, because that’s not the point of this article).
Some notes:

  • Make sure to use manual partitioning and use the free space (after the second NTFS partition) for your linux partitions.
  • If you want to use hibernate (suspend-to-disc), you’ll need a big enough swap partition – it should be at least as big as your main memory. My T500 has 4GB of RAM, my swap partition is 6GB.
  • Yes, you want to install grub to the MBR

Because I like my debian installation to be slim I always disallow apt to install the recommended packages of packages I install, by creating a file /etc/apt/apt.conf.d/06-norecommends with the following content:

        Install-Recommends "false";
        Install-Suggests "false";

But of course this is optional and has nothing to do with making Debian work on a Thinkpad ;-)

Getting WiFi firmware

After installing the basic stuff and rebooting to my new debian installation, I installed the WiFi firmware.
First I modified /etc/apt/sources.list to also use the contrib and non-free repositories, so the entries looked like this:

deb squeeze main contrib non-free
deb-src squeeze main contrib non-free

deb squeeze/updates main contrib non-free
deb-src squeeze/updates main contrib non-free

(Yours may look slightly different, depending on the mirror you selected).
After an apt-get update I installed the packages firmware-linux (not sure if this is really needed, maybe for the radeon) and firmware-iwlwifi (this one is definitely needed for wireless LAN, at least if you’ve got a “Intel Wifi Link 5100” or 5300 like me).

For using wireless LAN network-manager-gnome and the gnome-keyring (to store network keys) may come in handy. See my post on how to unlock the gnome-keyring on login when using the SLiM display manager for more on that.

Protecting you hard disk drive with HDAPS

Thinkpads have a cool feature to protect the HDD from falling damage: The IBM Active Protection System. On Linux this is supported by the HDAPS kernel driver and the hdapsd userspace daemon. To get a recent version of the kernel driver you have to install the tp-smapi driver package. It’s available in apt in both the tp-smapi-source package and the tp-smapi-dkms package (I installed the latter).
The hdaps daemon is also available via apt, the package is called hdapsd. It should just work out of the box.

Hibernate support

Hibernate works out of the box. But there’s a keyboard-shortcut to start hibernation, that doesn’t: Fn-F12. It sends a ACPI button/suspend message and by default there is no ACPI handler for that event. This can be easily fixed, though: Just create a file /etc/acpi/events/hibernatebtn with the following content and after a reboot the button should work:

# /etc/acpi/events/hibernatebtn
# Called when the user presses the hibernate button

event=button[ /]suspend

Disabling the PC speaker

To get rid of that annoying beep on several occasions (tab-completion, end of file in less, …), add the following to the /etc/modprobe.d/blacklist.conf file:

# no beeps, plz
blacklist pcspkr
blacklist snd_pcsp

Note that this doesn’t deactivate all beeps: The Thinkpad seems to beep independently of the OS e.g. on resume (after hibernate/standby) or when the power chord is plugged in or removed. specific stuff

The following stuff concerns It’s independent from a specific desktop environment (like XFCE, GNOME, KDE, …) – but it may well be that some of this can also be done with tools from the desktop environment.

Make the “UltraNav” (Touchpad/Trackpoint) behave the way I want

Both the Touchpad and the Trackpoint work out of the box. They can be further configured with a tool like gpointing-device-settings or similar tools from your desktop environment.
However, two things could not be configured with gpointing-device-settings:

  1. I want to be able to perform a click by tapping the touchpad. This should be configurable with gpointing-device-settings, but it didn’t work anyway, so I had to do it at configuration level.
    I created the directory /etc/X11/xorg.conf.d/ and within that directory a file called 10-synaptics.conf with the following content:

    # adapted from
    Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        # this enables clicking by tapping:
        Option "TapButton1" "1" 
  2. I want to be able to scroll with the Trackpoint by holding down the middle mouse button and moving the nipple. Also I want to emulate the third mouse button by pressing the other two – this is just out of habit, it’s not needed, because the middle mouse button works as well.
    So I created a file name 20-trackpoint.conf in the directory /etc/X11/xorg.conf.d/ (see above), with the following content:

    # adapted from
    Section "InputClass"
            Identifier      "Trackpoint Wheel Emulation"
            MatchProduct    "TPPS/2 IBM TrackPoint"
            MatchDevicePath "/dev/input/event*"
            Option          "EmulateWheel"          "true"
            Option          "EmulateWheelButton"    "2"
            Option          "Emulate3Buttons"       "true"
            Option          "XAxisMapping"          "6 7"
            Option          "YAxisMapping"          "4 5"

Special Keys

The Thinkpad has a lot of special keys (or key-combinations), e.g. to configure the brightness, the volume, …
Some of them (e.g. brightness) already work, but it’d be nice to have some additional on-screen information, other don’t do anything without further configuration.
(A special case is the hibernate button that I’ve mentioned earlier, because it is configured via ACPI handlers and not in X)
I used the desktop-independent xbindkeys tool (from the identically named debian package) to support those keys. The xbindkeys-config utility is really handy to modify xbindkey’s configuration file, ~/.xbindkeysrc. However, for xbindkeys-config to work you need a ~/.xbindkeysrc file (it may even be empty) or it’ll crash, so just execute

$ touch ~/.xbindkeysrc

before doing anything else.
After installing xbindkeys you should make sure it’s started when you log into X. One way to do so is to just add the following line to the ~/.profile file:

# ...
# start xbindkeys
xbindkeys &

Also most of the scripts for the special keys use the osd_cat tool from the xosd-bin package to display information on the screen, so you should install it.

Brightness Control

The keys to control the display’s brightness (Fn-Home/Pos1 and Fn-End) already work out the box. But it would be nice if the current brightness level (there are 16: 0-15) was displayed on the screen along with a nice bar.. the following script (save it to some dir in you $PATH, e.g. /usr/local/bin/ and make it executable (chmod 755 /usr/local/bin/ does that:


if [ -n "$XAUTHORITY" ]; then
        # kill other osd_cat processes to prevent overlapping
        if [ $(ps -A | grep osd_cat | wc -l) -gt 0 ]; then
                killall osd_cat
        i=$(cat /sys/class/backlight/acpi_video0/brightness)    
        let i_perc=(100*$i)/15
        osd_cat -d 1 -A center -p bottom -o 50 -c yellow -s 1 \
        -f -adobe-courier-bold-r-normal--*-240-*-*-m-*-iso8859-1 \
        -b percentage -P $i_perc -T "Brightness: $i / 15"

Make sure the path (/sys/class/backlight/acpi_video0/brightness) is correct for you or change it accordingly.
Now either use xbindkeys-config to make sure this script is called if either Fn-Home or Fn-End is pressed or add the following to the ~/.xbindkeysrc file (At the end I’ll paste my complete ~/.xbindkeysrc file.):

#brightness up
    m:0x0 + c:233

#brightness down
    m:0x0 + c:232
Switch Touchpad on/off

Fn-F8 is meant to toggle between touchpad, Trackpoint and both.. I see no point in disabling the Trackpoint so I just use it to disable/enable the touchpad.
So by pressing Fn-F8 you’ll get a nice OSD info saying “Touchpad OFF” or “Touchpad ON” and the touchpad will be switched off/on.
Save the following code as somewhere in your $PATH and make it executable:

# adapted from

if synclient -l | grep -q TouchpadOff[^[:alnum:]]*0 ; then     
   synclient TouchpadOff=1                                     
   status="TouchPad OFF"                                       
   synclient TouchpadOff=0
   status="TouchPad ON"

# kill other osd_cat processes to prevent overlapping
if [ $(ps -A | grep osd_cat | wc -l) -gt 0 ]; then
    killall osd_cat
if [ -n "$XAUTHORITY" ]; then
    echo $status | osd_cat -d 3 -p bottom -A center -o -50 -s 1 -c green \
    -f -adobe-courier-bold-r-normal--*-240-*-*-m-*-iso8859-1 

Add the following to your ~/.xbindkeysrc (or use xbindkeys-config to map the key yourself):

#toggle touchpad
    m:0x0 + c:199
Configure display

Fn-F7 is meant to configure display output (to the internal LVDS display or the external VGA and DisplayPort ports).
With Linux/ these configurations can be done with RandR. A nice GUI for randr is arandr (available via apt), so I just start arandr whenever Fn-F7 is pressed.
Note: Fn-F7 is identified as the XF86Display key. XFCE has a default mapping for that (it executes xrandr --auto which is supposed to do something useful, but..) so you may need to disable that default mapping. In XFCE that is done in the keyboard settings.

Add the following to your ~/.xbindkeysrc (or use xbindkeys-config to map the key yourself):

#configure display
    m:0x0 + c:235
Volume Keys

There are three keys to control the volume: One for mute, one to increase the volume and one to decrease it.
The script uses amixer (from the alsa-utils package) to change the volume and also outputs the current volume/status.
Save it as and make it executable (click “show source” to view):

#!/usr/bin/env bash
# adapted from


if [ "$1" = "-h" ] || [ "$1" = "--help" ] ; then
  p=$(basename $0)
  cat <<HERE

  Usage: $p <channel> <option>
  where option is in {+, -, m, u} or is a percent
  e.g. $p 50       # sets $CHANNEL to 50%
           $p Front m  # toggles the mute of the channel Front

  exit 0

if [ $# -eq 2 ] ; then

function vol_level {
  amixer get $CHANNEL |\
  grep 'Front Left:'  |\
  cut -d " " -f 7     |\
  sed 's/[^0-9]//g'

function osd {
  killall osd_cat &> /dev/null
  echo $* |\
  osd_cat -d 2 -l 1 -p bottom -c green -s 1 -A center -o 50 \
    -f '-adobe-courier-bold-r-normal--*-240-*-*-m-*-iso8859-1' &

function mute_osd {
        if [ $(amixer get $CHANNEL | grep Playback | grep "\[on\]" | wc -l) -gt 0 ]
                osd $CHANNEL Unmuted
                osd $CHANNEL Muted

function vol_osd {
  killall osd_cat &> /dev/null
  osd_cat -d 2 -l 2 -p bottom -c green -s 1 -A center -o 50 \
    -f '-adobe-courier-bold-r-normal--*-240-*-*-m-*-iso8859-1' \
        -T "Volume ($CHANNEL) : $(vol_level) %" -b percentage -P $(vol_level) &

case "$1" in
        amixer -q set $CHANNEL 5%+
        amixer -q set $CHANNEL 5%-
        amixer -q set $CHANNEL toggle
        amixer -q set $CHANNEL $1%

Note: Due to a bug, probably in the sound driver or hardware, muting doesn’t really work with this script (because muting master has no effect). Maybe I’ll fix the script to use a workaround later.
Update: Muting Master does work now (it actually has been working for months), probably due to an updated Kernel in Debian Squeeze.

Add the following to your ~/.xbindkeysrc (or use xbindkeys-config to map the key yourself):

#Volume Up
" +"
    m:0x0 + c:123

#Volume Down
" -"
    m:0x0 + c:122

#Volume (Un)Mute
" m"
    m:0x0 + c:121
Lock Screen

Fn-F2 is used to lock the screen. If you’re using xscreensaver you can just call xscreensaver-command -lock to lock the screen.
To do that add the following to your ~/.xbindkeysrc (or use xbindkeys-config to map the key yourself):

#Lock Screen
"xscreensaver-command -lock"
    m:0x0 + c:160
Battery Status

Fn-F3 has a battery symbol. I’m not sure what it’s supposed to do, but just displaying the current battery status (percentage and if it’s charging, discharging or whatever) may be nice.
The following script (save it as to you $PATH and make it executable) does exactly that:

# path to your battery. make sure it's correct

if [ -n "$XAUTHORITY" ]; then
        # kill other osd_cat processes to prevent overlapping
        if [ $(ps -A | grep osd_cat | wc -l) -gt 0 ]; then
                killall osd_cat
        BAT_FULL=$(cat $BAT_PATH/energy_full)
        BAT_NOW=$(cat $BAT_PATH/energy_now)
        STATUS=$(cat $BAT_PATH/status)
        let perc=(100*$BAT_NOW)/$BAT_FULL

        osd_cat -d 2 -A center -p bottom -o 50 -c yellow -s 1 \
         -f -adobe-courier-bold-r-normal--*-240-*-*-m-*-iso8859-1 \
         -b percentage -P $perc -T "Battery $perc % loaded, $STATUS"

Add the following to your ~/.xbindkeysrc to make it work:

#Battery Status
    m:0x0 + c:244

I haven’t mapped the remaining special keys (like play, pause, …) yet, but as you may already have guessed, this could easily be done with xbindkeys. Use either xbindkeys-config to do that or create the entries for the ~/.xbindkeysrc yourself – you can get the keycodes with xbindkeys -k.

My complete ~/.xbindkeysrc:

# xbindkeys configuration #
# Version: 0.1.3
# If you edit this, do not forget to uncomment any lines that you change.
# The pound(#) symbol may be used anywhere for comments.
# A list of keys is in /usr/include/X11/keysym.h and in
# /usr/include/X11/keysymdef.h 
# The XK_ is not needed. 
# List of modifier (on my keyboard): 
#   Control, Shift, Mod1 (Alt), Mod2 (NumLock), 
#   Mod3 (CapsLock), Mod4, Mod5 (Scroll). 
# Another way to specifie a key is to use 'xev' and set the 
# keycode with c:nnn or the modifier with m:nnn where nnn is 
# the keycode or the state returned by xev 
# This file is created by xbindkey_config 
# The structure is : 
# # Remark 
# "command" 
# m:xxx + c:xxx 
# Shift+... 

#keystate_numlock = enable
#keystate_scrolllock = enable
#keystate_capslock = enable

#toggle touchpad
    m:0x0 + c:199

#configure display
    m:0x0 + c:235

#brightness up
    m:0x0 + c:233

#brightness down
    m:0x0 + c:232

#Volume Up
" +"
    m:0x0 + c:123

#Volume Down
" -"
    m:0x0 + c:122

#Volume (Un)Mute
" m"
    m:0x0 + c:121

#Lock Screen
"xscreensaver-command -lock"
    m:0x0 + c:160

#Battery Status
    m:0x0 + c:244

# End of xbindkeys configuration

What also works (tested)

  • the webcam (tested with guvcview, vlc, google talk)
  • the card reader (tested with SDHC card)
  • Bluetooth (tested with Wiimote)
  • sound card
  • Hibernate (suspend to disk) and Standby (suspend to RAM)
  • VGA out (Displayport only works with the Radeon – also on Windows – so I haven’t really tested it on Linux. I guess you’d need the fglrx driver for that to work.)
  • Several hardware sensors (fan speed, temperatures). About half of the temperature sensors don’t work, though.. but who needs 16 temperature sensors anyway?
    Has anyone got a clue where those sensors (temp1 … temp16) are?

What doesn’t work

  • Switching the graphics adapter. With a newer kernel this should be possible – but not without restarting X. See this article at the ThinkWiki
  • Intels TurboMemory. This is supposed to speed up Windows boot, but basically is flash memory plucked into a PCI-Express port. Could be useful for Linux as well, but is not supported.
  • The fingerprint reader (Authentec 2810) is unsupported according to the ThinkWiki. I don’t care because most fingerprint readers can be fooled easily. Also I don’t like the idea of a robber not only stealing my laptop, but also cutting off my fingers.


Update: Output of lspci and lsusb

I figured it may be a good idea to paste the output of lspci and lsusb. Note that the radeon is disabled via BIOS, so it isn’t listed. I highlighted the lines listing non-working hardware.

  1. daniel

    you have had no problems with the intel display driver? on my t500 i get terrible display glitching across the bottom third of the screen making things almost unusable … the ati card behaves well with no problems

    i’m also using squeeze with all the latest updates applied

    Comment by lauren — 2011-01-19 @ 22:47 | Reply

    • Hi lauren,

      What kind of glitching? How does it look like? Is it permanent? Does it also occur on windows (if installed; then it’s probably a hardware problem)?
      On my T500 there only very rarely is a short glitch (<1sec), also in the bottom third of the screen..

      What desktop environment are you using? Maybe something with a compositing window manager? On the other hand, when I enable XFCE's compositor I still don't have any issues..
      Are you using a xorg.conf – IIRC fglrx, the proprietary driver for the ati card, needs this – if so, do you have any settings for the intel card?

    • Hm, I have the same problem. But I’m using fvwm as window manager and no compositing at all. I don’t use Windows, so I’m not able to find out if it is software or hardware problem.
      Anyway it is really annoying.

      On the other hand I’m happy that I’m not the only one with the same problem. It seems like some bug in intel drivers (they are known as not very well written drivers for the Linux although they are developed by big company with many engineers).

  2. Nice post, it made my x200 works perfectly.

    To make the mute button working, you need to add the option acpi_osi=”Linux” when you load the kernel.
    To do so you need to :

    1 – edit the file /etc/default/grub
    replace the line : GRUB_CMDLINE_LINUX_DEFAULT=”quiet”
    by : GRUB_CMDLINE_LINUX_DEFAULT=”quiet acpi_osi=Linux”

    2 – run the comand : update-grub2

    3 – reboot!

  3. I know it’s a year later but which wireless card were/are you using?

  4. A little off-topic, but I have a T500 running Debian Wheezy. I’ve had a few odd glitches. Not all plain sailing.

    I used to intermittently loose the keyboard entirely. Especially under Gnome 3. Mainly when I’d just got into some work with my dev environment (Sublime text, Chrome, Virtualbox.) That required a reboot to fix. Xfce feels much more stable.

    I don’t use the fingerprint reader – it was shockingly bad under Vista. Scrolling is worse under Vista, and Vista feels slower in general. I couldn’t run Bit Trip Runner (game) under Vista 32 at all, but it just about plays (jolts occasionally) on Debian 64. Worlds apart there.

    Sound has been another issue. I’ve got pulse audio (which I think installed as a dependency), sometimes I loose the sound. Going into the mixer I find it’s just muted a channel for no real reason that I can fathom. Sometimes restarting pulse helps…

    I only realised just how bad the sound sounds on my T500 today, I’d attributed problems to two pairs of headphones – it’s a weird farting sound. I’ve even had a range of frequencies totally drop. Some playback seems incredibly weedy. I can’t really figure out what’s going on with the mixer, overly complex under pulse. Would be easier with Alsa, but as said, Pulse is there installed due to a dependency.

    One more thing, whenever the machine wakes, there’s some DMA error listed, but it doesn’t seem to do anything bad. At least it suspends and resumes well. (Most of the time. I have had Chrome prevent me form suspending.)

    As for the hardware. I lost one keyboard to a minute bit of water. And the screen is a bit crappy (I’ve an led one.) Battery died. And power supply dead.

    It’s annoying that you can’t boot from the card reader, but you can from usb! Oh and people say the display port doesn’t carry audio.

    Thankfully I bought mine second hand, gripes aside, it’s been pretty good.
