Warning

I am not responsible for any damage on your computer in any way, neither due to lack of appropriate knowledge nor any other reason. So please first read deeper into the subject before changing a running system.

General Info

The article is for linux operation system only. Mainly ubuntu. If you are on hardy, you should only read that part, the same applies to gutsy.

This is a Thinkpad R31 2656-65G with

PIII M(obile) Intel Prozessor 1133 MHz - 512 KB cache (alternate link)
1024MB Ram (max)
(not very powerful) Intel i830 Grafics prozessor
100 Mbs Network
USB 1.1
No wlan (using Netgear WPN511 pcmcia card)
Trackpoint (no touchpad)
Bios Version 3.110 1FETF1WW (2004-11-16, Embedded Controller Version 02.29.12)
Mini PCI slot (only a short list of devices usable - please read this post and in thinkwiki
irda - NOT working for me (should do)
pcmcia slot - only one.

Unfortunatly, a very few time after I bought this laptop, a lot of better versions of the R-series thinkpads arrived. I noticed, that the USB 1.1 and sloppy Intel Graphics Chip where no good choice. Also the ACPI implementation is more than worse and IBM never really fixed it.

Within the next years with excessive use during my studies in computer science I had a lot of trouble getting the direct rendering and stable USB support running. This happens arround the time when the new 2.6 kernel series and the new Xserver (after 6.8) came up.

Nevertheless this is a thinkpad in best traditions, easy to use, comfortable and with excellent support. The latter I had to use 2 times replacing my motherboard.

Bios

Settings

Floppy, Serial Port, Parallel Port and Infrared Port are disabled
The PCI Settings are all set to auto (do not set the IRQs manually)

Custom ACPI table for linux

The bios acpi is buggy. Since I fixed it, my system is almost stable (some IRQ problems remain).

I use the latest Bios Version 3.110 1FETF1WW of 2004-11-16 and fixed the acpi table manually (which is not a trivial task).

!!! Read the documentation e.g. of ubuntu for this general task.
Use my DSDT.zip (contains the fixed DSDT.aml for the above Bios and my R31 modle only), unzip it and put it into the /etc/initramfs-tools directory.
Download the dsdt.dsl (!.dsl) from acpi.sourceforge and compile yourself. Unfortunately the dsdt.asl for my model is not usable.
Afterwards you have to add the kernel option acpi_no_auto_ssdt

(for kernel 2.6.24 and newer) and recreate your initramfs.

sudo unzip /wherever_downloaded/DSDT.zip -d /etc/initramfs-tools
sudo update-initramfs -c -k $(uname -r)

TEST: After reboot your dmesg should show something like

root@ibmr31:~# dmesg | grep DSDT
[  885.444768] ACPI: Looking for DSDT in initramfs... successfully read 20423 bytes from /DSDT.aml.
[  885.444823] ACPI: Table DSDT replaced by host OS

Now can be sure, your new DSDT was loaded.

External Hardware

Webcam

I use an Logitech Quickcam DeLuxe Netebook using the gscpa driver

cd /usr/src
apt-get install gscpa-source
tar xjvf gspca.tar.bz2
module-assistent a-i gscpa

Unfortunatly this cam uses to crash randomly with the NEC pcmcia USB 2.0 card. Also the pcmcia slot is used by the wireless card ... so the "notebook" webcam sits upon my desktop pc ;(

PCMCIA Wireless

Using a netgear WPN511 54Mbs pcmcia card (Range Max, but 108Mbs not working for me). The output of lspci is:

02:00.0 Ethernet controller: Atheros Communications Inc. 
       AR5212/AR5213 Multiprotocol MAC/baseband processor (rev 01)

For ubuntu hardy i needed to get the actual madwifi (atheros) driver to get the card working, the 8,04 atherors drivers are not up to date:

apt-get install madwifi-tools linux-restricted-modules-$(uname -r)

Now invoke this little script (or exec line by line)

#!/bin/bash
MADWIFI="madwifi-nr-r3366+ar5007.tar.gz"

sudo apt-get update
sudo apt-get install build-essential
[ -e ${MADWIFI} ] || wget 'http://snapshots.madwifi.org/special/${MADWIFI}'
[ -e ${MADWIFI} ] || tar zxvf madwifi-nr-r3366+ar5007.tar.gz
cd madwifi-nr-r3366+ar5007
make clean
make
sudo make install

Reboot the machine and enjoy stable wlan ;)

New burner in ultrabay

Bought a standard slimline dvd burner from Teac for about 80 € / 60 $, applied the parts from the original CD/DVD. I simply took the old ultrabay cd/dvd combo to the dealer and looked about a matching slimline burner ;)

I had to fiddle around a little bit with the outside cover to fit, but it works like a charme for years now:

TEAC DVD Model No. SD-R6472

Ubuntu Hardy / 8.10

Xorg

There occured major problems due to the new Xorg driver for the intel graphics chipset. Most problems had gone since 8.04 but there are artifacts that make life harder and are looking very ugly. The problem may be fixed by enabling the XAA rendering engine (default is EXA).

--Apos 13:23, 10 March 2009 (CET)

So here's the xorg.conf that fixes those problems and (!) enables the dual screen function, if you attach a monitor on the laptops vga output connector:

Skype and Logitech Quickcam Notebook Deluxe with gstfakevideo

Skype permanently crashed on video chats. The follwing article led me into the solution:

HOWTO: Skype und Logitech E2500 Webcam via GSPCA

Login as root in a terminal

sudo su
cd /usr/src

Download an install gstfakevideo (which will later start your skype):

sudo apt-get update
sudo apt-get install libgstreamer0.10-dev gstreamer-tools svn-buildpackage
svn checkout http://gstfakevideo.googlecode.com/svn/trunk/ gstfakevideo
cd gstfakevideo
make
sudo make install

Alter your skype starter in your gnome menu with this command (you can test it previously in a terminal)

gstfakevideo v4lsrc device=/dev/video0 ! ffmpegcolorspace

That's it. No mor hasssle. No crashes any more ;)

Ubuntu Hardy / 8.04

Remark: This sections mainly shows the differences to the gutsy / 7.10 installation.

Kernel

Boot parameter

Use the kernel parameters as shown in Gutsy. Be aware that no linebreaks in /boot/grub/menu.lst are allowed for # kopt ...:

# kopt=root=UUID="YOUR_UUID" irqpoll i8042.nomux=1 acpi_no_auto_ssdt
acpi_sleep=s3_bios hpet=force splash quiet ro locale=de_DE

"acpi_sleep=s3_bios" - for hibernation to function properly use

Then do

update-grub

which applies these setting automatically to all kernels.

"acpi_no_auto_ssdt" - for custom DSDT.aml to apply
"hpet=force" - power managment
"ec_intr=0" - for some thinkpads when hanging on suspend/resume (don't really now if this applies to other R31/R30 laptop - I don't need it)

Buggy ACPI

The existance of the custom ACPI table "/etc/initramfs-tools/DSDT.aml" is not used by default by initramfs-tools any more (kernel 2.6.24 and newer). Therefore you must specify the "acpi_no_auto_ssdt" as boot parameter so that the custum DSDT is compiled into the initramfs file of the kernel.

-> Please read the section above for creating a custom DSDT.

Kernel generic

It is NOT necessary any more to use the i386 Kernel. The "generic" flavour (default) runs fine.

Usplash

usplash run's fine - there is no interfere with Xorg and no need to remove the "splash" kernel parameter.

ACPI - power management

General Info

Attention pm-utils: ubuntu hardy/8.04 uses pm-utils package for hibernation/suspend. The scripts are located in /usr/lib/pm-utils/ and all customizations in /etc/pm/. Despite many other posts editing the file /etc/default/acpi-support like in gutsy/7.10 has NO effect any more in hardy/8.04!

Please read e.g. here about how pm-utils work. You can also call man pm-suspend in a console window to get informations.

Very good infos for kernel 2.24 are here:

thinkwiki - How to reduce power consumption

According to this link, I put the following in /etc/rc.loacl (some mentioned in the above link don't work on my machine):

echo 5 > /proc/sys/vm/laptop_mode
echo 0 > /proc/sys/kernel/nmi_watchdog
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
for i in /sys/bus/usb/devices/*/power/autosuspend; do echo 1 > $i; done
hal-disable-polling --device /dev/scd0hal-disable-polling --device /dev/scd0

For harddisk I use the option noatime.

Adding pm-utils quirks for HAL

Links:

For suspend getting to work properly with hal (the hardware abstraction layer), we need to activate the appropriate informations - so called quirks - into an .fdi file specifying

the exact model infomation of our machine
the quirks to apply

These quirks could be set individually in

 /etc/pm/config.d/config

Mine are disabled:

#DISPLAY_QUIRK_S3_BIOS="true"
#DISPLAY_QUIRK_DPMS_ON="false"
#DISPLAY_QUIRK_VBESTATE_RESTORE="false"
#DISPLAY_QUIRK_VBEMODE_RESTORE="false"
#DISPLAY_QUIRK_RESET_BRIGHTNESS="false"

The reason is, because a better way is to add the quirks right into hal's hardware list.

Find out your model information. My notebook type is an 2656-65G. So I do:

$ hal-device | grep 2656
system.hardware.product = '265665G'  (string)

This gets me the product number used by hal (265665G) and the type (string).

We are adding this to the following file, that already lists a lot of other notebooks from ibm:

vim /usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-ibm.fdi

     <match key="system.hardware.product" string="265665G">
        <match key="system.firmware.version" prefix="1FETF1WW">
           <merge key="power_management.quirk.s3_bios" type="bool">true</merge>
           <merge key="power_management.quirk.dpms_suspend" type="bool">false</merge>
           <merge key="power_management.quirk.vbestate_restore" type="bool">false</merge>
           <merge key="power_management.quirk.vbemode_restore" type="bool">false</merge>
         </match>
     </match>

Now restart the hal service:

/etc/init.d/hal restart

You can check, if the settings applied:

$ hal-device | grep quirk
 power_management.quirk.s3_bios = true  (bool)
 power_management.quirk.dpms_suspend = false  (bool)
 power_management.quirk.vbestate_restore = false  (bool)
 power_management.quirk.vbemode_restore = false  (bool)

Gnome

Set the according section of the cpu scaling to ondemand in power management settings.
Disable the suspend action.

Hibernation

Hibernation works now (hardy). Two minor problems remain:

Screen stays blank after resume from suspend - I pointed out my suggestions here . Or manually switch with Ctrl+F7 or F9 to the X console. This solution might be wrong because the scripts in /etc/acpi/sleep.d/ should not be used in hardy.
No sound after resume from hibernation. I posted the solution in bug #198218.

Supend to ram (sleep mode)

Does not work and system freezes upon wakeup. Disable in the power management settings.

Xorg

[Update --Apos 11:33, 14 June 2008 (CEST)]

bug 14528 is back. DRI not working in 8.04. System freezes. ;(

DRI is not usable after a cold boot. I filed a bug at freedesktop.org and ubuntu launchpad. The system freezes upon X start.

See:

xorg.conf

This file is much shorter since 7.10 and the use of the "intel" driver (no DRI so far). This means you cannot use compiz or metacities composite extension. (see next section for a quick hack enabling compiz).

Basic changes:

intel driver cares of most settings automatically now
use of default depth 16 for the chipset of the i830M (R31) is MANDATORY. Depth 24 will give you trouble, trouble, trouble and less quality.
DRI disabled

EndSection

xorg.conf with EXA

There is a quick hack for using e.g. the metacity composite extension, but not DRI, which would cause the system to hang.

Add the following to the Device section of the xorg.conf: Option "AccelMethod" "exa" Option "MigrationHeuristic" "greedy" Option "ExaNoComposite" "false"

Be aware, that this is just a hack for using the composite extension. It would be incredibly slow for opengl applikations because hardware acceleration the i830M chipset would be able to do is not used!

Compiling intel driver from git

If you know what you are doing, you can compile the intel driver from git repository:

#!/bin/bash

/etc/init.d/gmd stop

sudo apt-get install git-core autoconf automake libtool
sudo apt-get install xorg-dev libdrm-dev mesa-common-dev build-essential

cd /tmp
git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-intel
cd xf86-video-intel

sh autogen.sh
make

sudo cp /usr/lib/xorg/modules/drivers/intel_drv.so /usr/lib/xorg/modules/drivers/intel_drv.so.backup
sudo cp src/.libs/intel_drv.so /usr/lib/xorg/modules/drivers/intel_drv.so

/etc/init.d/gmd start

Ubuntu Gutsy / 7.10

Kernel boot parameter

There are some problems running this laptop with a modern 2.6.x linux kernels. Do not set the IRQs in the bios's PCI section manually or your xserver will fail with DRI.

The problems resulting in misbehaviour of your ethernet or usb are all related to a wrong ACPI table of your bios. This is a known bug for many bios's.

Please see

Debug: How to Isolate Linux ACPI Issues

for additional informations about ACPI and the linux kernel.

i386 Version of ubuntu kernel

I am using the actual ubuntu 386 kernel 2.6.14-2-386.

apt-get install linux-image-386 linux-restricted-modules-386

But the generic version seams to run also with the applied changes in this section. (20:08, 25 December 2007 (CET))

Trackpoint

The trackpoint does erratic mouse movements out of the sudden

Solution:

add i8042.nomux=1 as kernel parameter

See

ThinkWiki - Problem with checking battery status

Failure on IRQ - unusable USB/Ethernet

An IRQ problem leaves the usb and ethernet bus unusable . The dmesg message is

dmesg | grep nobody
# irq 11: nobody cared (try booting with the "irqpoll" option)

Solution:

add irqpoll as kernel parameter (this works for my thinkpad submodel - it might not work for you)
adding noirqdebug will remove the debug messages

This leads into the following /boot/grub/menu.lst additions

## ## Start Default Options ##
## default kernel options
# [...]
# kopt= [...] ro irqpoll i8042.nomux=1

If you are using an pcmcia usb 2.0 card doing the following might restore the ethernet or usb port in case of a failure

modprobe -r ehci-hcd && modprobe ehci-hcd

Unfortunately the problems appeared for all linux 2.6 kernels by now. It also affects a lot of other thinkpad users. See Bug 8853 irq NN: nobody cared on ThinkPad X61T,T61.

Usplash

Direct rendering might (!) be broken, if you use usplash.

Uninstall usplash

apt-get remove usplash && update-initramfs -c -k `uname -r`

Thinkpad buttons

Don't seem to work with actual 2.6.22 kernels due to "new and fixed" thinkpad-acpi (former ibm-acpi) modules. The problem is, that these "fixes" seam to make the buttons unusable - not just on this kind of older thinkpad model.

For volume-control I use the keyboard shortcut settings of gnome in conjunction with the back/forward buttons on the lower right side of the keyboard.

/etc/network/interfaces

With support for tuntap, used by virtualbox. Change a_username with the user that uses the tapX device with virtualbox or other emulator software.

Xorg

GLX and DRI works, but it is a little buggy and not very performant. I don't recommend using compiz (desktop effects). Also compiz uses a few percent (~2 %) of additional cpu power and causes some artifacts in some OpenGL applications, like e.g. celestia or stellarium.

Troubleshooting

I had some real trouble getting X11 with direct rendering to work after a system upgrade of the xserver occured. X11 hung and the whole system froze. I assume that the main reason for this is the buggy ACPI implementation found in this - and many other - machines. But it also might be a bug in the xserver-xorg drivers from intel.

Heres what I did to things fixed permanently

Prerequesites: Use the fixed ACPI table from the Bios section above !!!

1. I removed usplash and run update-initramfs for the used kernel flavours on the machine. You can try to leave this step, probably your system works with usplash (mine did not).

apt-get remove usplash usplash-theme-ubuntu
update-initramfs -c -k $(uname -r)

2. I reinstalled the xserver-xorg-video-intel driver package and xorg-video-core from the gutsy installation CD.

cd /where/the/xserver-xorg-video-*-files-are-on-Install-CD
dpkg -i xserver-xorg-core* xserver-xorg-video-*

It might be additionally necessary to uninstall the xserver-xorg-video-intel and only use the xserver-xorg-video-i810 driver

apt-get remove xserver-xorg-video-intel

You then have to use the i810 driver in the xorg.conf instead of the intel driver.

3. Take care, that the xserver-xorg files are not updated. Therefore edit the 50unattended-upgrades file from the package manager.

nano /etc/apt/apt.conf.d/50unattended-upgrades

// never update the packages in this list
Unattended-Upgrade::Package-Blacklist {
//      "vim";
        "xserver-xorg-video-intel";
        "xserver-xorg-video-i810";
        "xserver-xorg-video-all";
        "xserver-xorg-core";
        "xserver-xorg";
}

4. I rebooted the machine

Now the Xserver should work with direct rendering.

X11

Trackpoint

The trackpoint can be configured specially for scrolling in conjunction with the middle mouse button. See the xorg.conf in one of the following sections.

OpenGL/Video playback- gl - gl2

For playing videos don't use the gl of opengl drivers for your video playback.

The x11 od xv driver work flawlessly. Alter your mulimedia settings accordingly.

Additional informations for ACPI issues

As I mentioned above see

Debug: How to Isolate Linux ACPI Issues

for additional informations about ACPI and the linux kernel.

These are ACPI related boot parameters and how they behave in conjunction with ubuntu gutsy and the R31:

acpi=off       (leaves the system unbootable)
acpi=ht        (leaves the system unbootable)  
acpi=noirq     (leaves the system unbootable)
pci=routeirq   (no positive effect)
pnpacpi=off    (no positive effect)
pci=noacpi     (no positive effect)
noapic         (not tested)
nolapic        (not tested)
irqpoll        WORKS

If you change one of them you have to run update-grub AND update-initramfs -c -k `uname -r`. Remember to always keep a kernel that will boot, either the generic or the 386 flavor. Never (!) run with update-initramfs -c -k all on all installed kernels .

A special page for ACPI issues with Thinpads you'll find here:

Thinkwiki - How to make ACPI work

Here is what happens to the bus even when booting with irqpoll (but the system keeps working):

cat /var/lib/acpi-support/*-*
 1FETF1WW (3.110)
 IBM
 265665G
 Not Available

acpi_listen

acpi_listen
 button/power PWRF 00000080 00000001

is not responding to the Volume Keys, only the power button.

The IRQ problems might look as followed:

dmesg | grep  0000:00:1f.1
 [   15.932137] ata_piix 0000:00:1f.1: version 2.11

 [   18.446723] [<f8878590>] (usb_hcd_irq+0x0/0x60 [usbcore])

In the next you can see that IRQ 11 ist running at a much too high level, causing the system to crash. This is probably a not fiixed bios problem.
