Configure Kernel (done in /home/chrism/bus/t42p/linux-2.6.8.1/config-chris)

• I actually ended up not using any of this because I'm settled on Ubuntu and didn't need to change the stock kernel to get most things working. I still haven't changed the Ubuntu default kernel. As a result I cannot do software suspend, but suspend to RAM works ok. The rest of this section is from research I did before actually getting the laptop.
• Config 2.6.8.1 files available at http://modular.fas.harvard.edu/t42/config-2.6.8.1 and http://www.stanford.edu/~sanjiv/thinkpad/config-2.6.8.1-sinha

  Using sanjiv's. Differences:

      CONFIG_MODVERSIONS: off
      CONFIG_BLK_DEV_IDECD: kernel instead of module
      E1000: kernel instead of module
      E1000_NAPI: on
      Networking support -> Bluetooth subsystem support: kernel

      BT_RFCOMM_TTY: kernel
      BT_BNEP: kernel
      BT_HIDP: kernel
      BT_HCIUSB: module (should be kernel)
      BT_HCIUSB_SCO: module (should be kernel)
      BT_HCIBT3C: module
      PHONE: module
      FB_VESA: off
      FB_RADEON: on (as per sanjiv's addendum)
      VIDEO_DEV: on (Video for Linux)

• Need to set swsusp2 partition to your own swap partition.

  NOT DONE (need to know partition number)

• 2.6.9-rc2+ has speedstep-centrino support for the Dothan 1.8Ghz.

  Not using this, usin 2.6.8.1, due to ease of sanjiv's patches

• CONFIG_MODVERSIONS no? Madwifi FAQ recommends.

  This was enabled

• ACPI Processor P-States driver on (and stuff beneath it that is relevant).

  Part of Sanjiv's stuff.

• paches necessary for 2.6.81: speedstep-centrino, bk-cpufreq, acpi, bootsplash (at http://www.stanford.edu/~sanjiv/thinkpad/patch-2.6.8.1.tar.bz2)

  Applied.

• Compile filesystem and ide into kernel in order for initrd to work properly.

  Done.

• Enable RAM disk under block devices.

  Done.

• Disable "Local APIC support on uniprocessors" under "Processor type and features" (CONFIG_X86_UP_APIC) (system poweroff on halt).

  Turned off.

• REGPARM off (resume from hibernate needs it, according to William Stein)

  Turned off.

• Turn ACPI on.

  On.

• Turn APM off.

  Off.

• Configure in IDE_CD (CONFIG_BLK_DEV_IDECD) (to kernel?)

  In kernel

• Configure e1000 module into the kernel (to prevent resume failures) also CONFIG_E1000_NAPI=y

  Done.

• Ensure kernel has proper iteration of centrino speedstep (http://modular.fas.harvard.edu/t42/).. Apparently 2.6.9 already has this but 2.6.8.1 needs a patch.

  Done via Sanjiv's patches.

• Configure kernel to not have a special graphics support (frame buffer device), makes ATI nonfree drivers more robust according to WS.

  NOT DONE (try with fb enabled RADEON first)

• "nvram module" (sanjiv claims this exists, needed for tpb)

  CONFIG_NVRAM is a module

Buy

• Blank DVDs and CDs

Prep

• Burn CDs using Access IBM

  Done (in red case)

• Install RAM.

  Done

• Copy C:\186, C:\DRIVERS, C:\VALUEADD to a bootable CD (BartPE downloaded to VMWare desktop on athlon, needs Windows XP CDs)

  Didn't do this

• Copy C:\IBMTOOLS to DVD-RAM

  Didn't do this

• Print device info

  Couldn't do this (no printer)

• Defrag the NTFS partition.

  Yup. Although it was not necessary.

• Use PM 7 to resize NTFS partition (dont delete IBM_SERVICE partition unless necessary).

  Yup. Although I bought PM8 in the process (didn't try PM7).

• Turn on speedstepping in Windows (XP->System->Energy->Extended->CPU->Automatic)

  Yup.

• Firmware/BIOS updates as necessary ( http://www-1.ibm.com/support/docview.wss?rs=0&q1=t42p&uid=psg1MIGR-55386&loc=en_US&cs=utf-8&cc=us&lang=en )

Install Linux

• Run down the battery while doing this.

  Battery got run down.

• Install warty first, then FC3 (if warty gets fucked up, thats ok).

  Warty recognized and configured speedstep and atheros wireless properly. Fedora didn't do atheros (and I didn't bother setting it up).

• Give a 2.7GB (2 * 1.333) swap partition to Linux (for swsusp2).

  Yup.

• FC2 fucks up Windows partition, make sure you know how to prevent. by reading http://lwn.net/Articles/86835

  FC3 had no problems. Ignorance was bliss.

Installing the Kernel

• Creating an RPM (see http://www.fedoraforum.org/forum/article.php?a=4 and http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/custom-guide/ch-custom-kernel.html)

  (Didn't do it (Ubuntu's kernel worked ok))

Configure Boot-Time Params

• pci=noacpi acpi_sleep=s3_bios

  Done in fedora by editing /boot/grub/menu.lst

  In Ubuntu, done by editing /boot/grub/menu.lst and adding these options to the kopt= lines, then running sudo update-grub

• when swsuspend is working: resume=/my/swap (sanjiv)
• when swsuspend is working: resume2=swap:/dev/hda5 (gentoo)
• Ensure to make a duplicate entry in grub without the resume= line.

  (swsuspend not in Ubuntu kernel, so giving up)

Daemons That Should Run

• acpid

  Yup

• cpufreqd

  Nope. Don't need it under ubuntu. Reason: ubuntu uses powernowd instead.

Tuning

• Check hdparm. WS has this::

       sh-3.00# /sbin/hdparm -t /dev/hda1
       /dev/hda1:
       Timing buffered disk reads:   92 MB in  3.06 seconds =  30.08 MB/sec
  

CPU Frequency Stepping

• If compiling speedstep as a module (I haven't), you will need to load the "speedstep-centrino" module while running the new kernel to enable speedstep. The way to check if speedstep is enabled is to look for entries under /sys/devices/system/cpu/cpu0/cpufreq/. I use cpufreqd to manage speedstepping dynamically.

  NOT NECESSARY in Ubuntu

• According to gardner, latest FC2 errata kernel has speedstep working.

  UNCONFIRMED

• Here is a cpuspeed.conf file: http://www.sas.upenn.edu/%7Evbraun/computing/T41/cpuspeed.conf

  Not needed (cpufreqd.conf instead)

• GNOME CPUFreq applet at http://www.gnomedesktop.org/article.php?sid=1664 and FC2 RPMs are at http://dag.wieers.com/packages/gnome-cpufreq-applet/

  Working under Ubuntu

• Whoever from WS page: For whatever reason cpufreqd doesn't seem to work for me. However, directly echo'ing speeds into /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq and /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq does work for me, and that's enough because it means I have control (I can make a command or icon that speeds up or slows down my computer). For example, to set the computer at maximum:

       echo 1800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
       echo 1800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
       echo 1800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
  
      And, to set it at minimum speed::
  
       echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
       echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
       echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
  
      using nothing whatsoever under Ubuntu works fine for me, so no need for this
  

• http://modular.fas.harvard.edu/t42/speedstep-centrino.c-version2.6.8.1 (doesn't seem to work automatically with cpufreqd)

  This is unnecessary at least under ubuntu.

Laptop-mode

• Should just work if apcid is running. Configuration advice for settings is available from http://www.xs4all.nl/~bsamwel/laptop_mode/ and /usr/src/linux-2.6.6/Documentation/laptop-mode.txt

  Laptop-mode is now enabled when the box is remvoed from ac power (via an acpi event)

Configure X

• Ubuntu warty has binary drivers (see below).
• Debian packages available from http://xoomer.virgilio.it/flavio.stanchina/debian/fglrx-installer.html

  Didn't use.

• Binary ATI drivers at http://www.ati.com/support/drivers/linux/radeon-linux.html

  Didn't use

• XF86Config available from http://www.stanford.edu/~sanjiv/thinkpad/XF86Config-4

  I used this as a jumping-off point but added stuff for Synaptics touchpad later.

• Fedora howto at http://www.fedoraforum.org/forum/showthread.php?t=16690

  Didn't bother.

• Free/OSS driver ok in xorg, apparently, although XFree86 free drivers are broken (causes hangs randomly).

  Not using OSS drivers much, so couldn't confirm under Ubuntu.

• Sanjiv reports that OSS drivers cause mouse/touchpad hangups on resume.

  Unconfirmed.

• Comment out "dbe" and "glx" from XF86Config in order for swsusp2/suspend-to-ram to restore OK. Maybe just "glx".

  Just uncommenting just "glx" works fine.

• Change /etc/kde3/kdm/Xservers and add "-dpi 120" to ::0 line if things look weird.

  Edit /etc/gdm/gdm.conf after "audit" to do same for gdm.

• Synaptics touchpad drivers available from Synaptics or from apt-get xfree86-drivers-synaptics (sanjiv)

  I got xfree86-driver-synaptics from apt and changed XF86Config according to its docs (including the trackpoint as a second input device and making it "alwayscore")

• VMWare requires the DGA extension for full-screen mode, so change the line that says:

  SubSection "extmod" Option "omit xfree86-dga" EndSubSection

  to read:

       Load "extmod"
  
     This was
     done.
  

• Useful as screen saver? There's a package called radeontool that lets you control the backlight. Running radeontool light tells you the current status of the backlight; tacking on or off to the end turns the backlight on or off, respectively. (gentoo)

  Didn't bother.

• For ubuntu (excellent advice from Robert):

       <zwark> uncomment the universe lines in the sources list
       <zwark> search for fglrx in synaptic
       <mcdonc> aha... 
       <zwark> install the restricted kernel modules as well as the drives
       <mcdonc> i'm on fedora now but may switch back
       <zwark> set the flag I mentioned above to no (see below)
       <zwark> then it "should" work
       <mcdonc> i just got this thing today and i've been fucking with it all day
       <zwark> So if you try again you will need: Non-free Linux 2.6.8.1
       modules as well as fglrx-driver and maybe the hint with Option
       "UseInternalAGPGART" = "no". If x comes up and fglrx-info says ATI
       is used for rendering, everything is fine.  Good luck
       <mcdonc> you're the man!
  
     This worked like a champ.  I needed the following modules:
  
       - fglrx-driver
       - fglrx-control
       - fglrx-driver-dev
       - linux-restricted-modules (I used 2.6.8-1-3-686)
  

Configure swsusp2

• I didn't configure swsusp2 at all, too much hassle to recompile kernels; all the below is from research I did before getting the laptop.
• hibernate.conf available from http://www.stanford.edu/~sanjiv/thinkpad/hibernate.conf
• Remove mountnfs.sh from /etc/suspend.conf
• Might need to turn off /etc/default/ifplugd's HOTPLUG_INTERFACES for madwifi interface (manually name hotplug interfaces instead). See http://modular.fas.harvard.edu/t42/.
• PCMCIA may not work when restoring from swsusp2: check.
• Suspend script:

  /etc/init.d/hotplug stop # very important echo 3 > /proc/acpi/sleep /etc/init.d/hotplug start & # this gets run when sleeping is done. /usr/local/bin/fakex # see http://modular.fas.harvard.edu/t42/

  Fakex is required to prevent X from operating slowly on resume

• USB and ethernet need to be unloaded on suspend (see sanjiv at http://www.stanford.edu/~sanjiv/thinkpad/thinkpad.html)
• you need to remove the ehci_hcd module before suspending or resuming (gentoo)
• Map lid buttons: After apcid is installed, modify the /etc/acpi scripts used by acpid to map the lid button to a sleep event and the power button to a wake event. I remove usb modules before suspending through "/etc/init.d/hotplug stop" in my sleep script. After waking "/etc/init.d/hotplug start" is unable to start ehci_hcd and uhci_hcd but they can be manually loaded.
• Standby and hibernate should be sudo'd wo password (sanjiv)
• ibm-acpi driver necessary to get Fn key combos recognized as ACPI events (sanjiv)
• unmount any windows partitions on hibernate!
• when swsuspend is working: resume=/my/swap (sanjiv)
• gardner says:

  In order to use SWSUSP2, you must append the line in your /etc/grub.conf file according to the instructions on the swsusp website. Then, you must run the suspend.sh script according to the swsusp website instructions, which will create the files /etc/suspend.conf and /usr/local/sbin/hibernate.

  Everything worked fine for me after un-suspending except for wired ethernet and USB. The USB issue can be easily fixed by adding "ehci_hcd uhci_hcd" to SWSUSP_REMOVEMODS and SWSUSP_INSERTMODS in /etc/suspend.conf to force swsusp2 to remove the USB modules upon suspend and then reinsert them upon unsuspend. The ethernet adapter problem is a little more complex, but I have discovered that manually shutting down the eth0 interface (ifdown eth0) and them removing the e1000 module (rmmod e1000) before suspend will guarantee that the module will load properly when networking is restarted after unsuspending. For some reason, I cannot get this to work automatically (as in the case of USB). I will update here when I experiment more.

• ACPI files from gardner: http://pmw.org/~gardnerj/Thinkpad/my_acpi.tgz
• swsusp2 patches for 2.6.8.1 are apparently available (software-suspend-2.0.0.109-for-2.6.8.1)

  for patchfile in ../software-suspend-2.0.0.109-for-2.6.8.1/*; \ do patch -p1 < $patchfile; done

• If problems like kernel/power/suspend.c:1455: error: `KERNEL_DS' undeclared (first use > in this function when compiling swsusp2, see http://lists.berlios.de/pipermail/softwaresuspend-devel/2004-September/000555.html
• Testing swsusp2 in new way (requires resume2=):

  rmmod ehci_hcd echo -n "disk" > /sys/power/state; #SuspendToDisk modprobe ehci_hcd ;

  • OR older way (requires resume=) -

  echo 4 > /proc/acpi/sleep

• I did no configuration of swsusp2 as it's not built into the Ubuntu kernel.

Configure suspend to RAM

• Took William Stein "a while to figure out" under 2.6.8.1, no other details. From other stuff I've read I think it should just work?

  I needed the ibm-acpi module from ibm-acpi.sourceforge.net and then I mapped an acpi event to the sleep button to go to sleep. Used the "acpi" example directory in ibm-acpi package as a replacement for the /etc/acpi directory that shipped with acpid.

• Suspend-to-RAM initially kills sound. Fix it by stopping alsasound and starting it after resuming. After starting alsasound, modprobe snd-intel8x0 and run /usr/sbin/alsactl -f /etc/asound.state restore to restore the mixer settings.

  I didn't have this problem.

Wireless

• Ubuntu atheros worked out of the box, I didn't configure shit; the rest of this is from preresearch.
• Install sharutils (Fedora), madwifi needs them.
• Gardner: install the wireless-tools-26-4 RPM for FC2 before installing madwifi drivers.
• Madwifi drivers (apparently latest CVS version doesn't compile against 2.6.8.1), patch available at http://modular.fas.harvard.edu/t42/
• MadWifi install instructions: http://www.mattfoster.clara.co.uk/madwifi-faq.htm
• export COPTS="$COPTS -DSOFTLED" to see lights come on for wireless.
• To start the interface, ensure the drivers are loaded with modprobe ath_pci, then bring up the ath0 interface with ifconfig ath0 up. Now try iwlist ath0 scan, and you should see information about all access points that your wireless card can detect.
• Install wavemon (http://www.janmorgenstern.de/projects-software.html)
• Install kismet (http://modular.fas.harvard.edu/t42)
• Kudzu misconfigures wireless (eth0 instead of ath0)

CD/DVD

• edit /etc/cdrecord/cdrecord to say CDR_DEVICE=/dev/cdrom

  Didn't need to do this.

• Might need to modprobe ide-cd

  Didn't need to do this.

• apt-get install regionset on Debian and run (set to 1).

  Did this.

• K3B helps set proper permissions.

  Got k3b from apt under Ubuntu and it works fine.

• Playing DVDs DVDs using ogle kinda work. At least some of them do.

Configure tpb:

• Debian: from apt-get tpb

  Yup.

• Fedora: included in xosd and tbp rpms that ship with Fedora.

  Couldn't find em.

• modprobe nvram

  Ubuntu (added "nvram" to /etc/modules)

• chmod a+rw /dev/nvram

  Did this in a startup script in Ubuntu.

• Need a line in Autostart to a shell script that runs the actual GUI piece

  #!/bin/bash exec tpb --osd=on --verbose --thinkpad="/usr/bin/gnome-terminal"

Configure ibm-acpi:

• Download the package from http://ibm-acpi.sourceforge.net and do "make; make install". Then add ibm_acpi to /etc/modules (Ubuntu).

  Worked good.

Modem:

• Get Conexant HSF softmodem driver from Linuxant

  Ubuntu: debian package requires makedep'd linux source

  XXX not done: this isn't the right driver. I need a slmodem driver, I think? Actually no idea. The modem reports CXT from Windows, so who knows.

Sound:

• Should just work (and does in both Ubuntu and Fedora)
• Check if can play multiple sounds at once (if not, maybe mux). See http://modular.fas.harvard.edu/t42/
• VMWare has some sound issues... choppiness. Haven't investigated.

IR:

• Who knows

Bluetooth (for GPRS):

• Install bluez

  From apt for ubuntu

• Configure rfcomm to my phone, in /etc/bluetooth/rfcomm.conf:

     rfcomm0 {
        device XX:XX:XX:XX:XX:XX;
        channel 1;
        comment "My T610";
    }
  

• GPRS to T-Mobile

  Just used the normal network connection setup tools and then hand-edited the resulting wvdial.conf and came up with:

      [Dialer ppp0]
      Modem = /dev/rfcomm0
      Baud = 57600
      SetVolume = 10
      Init2 = ATL2
      Password = 123
      Stupid mode = 1
      Init1 = ATZ
      Phone = *99***2#
      Username = 123
      Dial Command = ATDT
      FlowControl = Software (XON/XOFF)
  

• OBEX pictures

  Tried halfheartedly but phone won't sent to machine with obexserver running.

Backups

• How?

Software

• VMWare

  Done. On reboot, VMWare wont stay configured. Fixed via http://www.braincells.com/debian/2004/05/

• Komodo
• Evolution

  Done.

• Emacs

  Done.

• Mozilla (web dev tools)

  Firebird under Ubuntu is cool.

• K3B

  K3B seems to work.

Misc Ubuntu

• Uncomment "universe" line from /etc/apt/sources.list to get everything
• Install zlib1g-dev package to get Python compiles to create zlib.so
• Install libncurses5dev to make sure mysql compiles
• Install bison so mysql compile doesn't croak
• Make a link from /usr/include/des.h to /usr/includeopenssl/des.h to allow cyrus-sasl to compile
• Install redhat-artwork package deb to get Bluecurve theme
• kernel-headers package required for VMware compile.

Problems and Resolutions

• Configure all PCI IRQs for Auto (if ath0 locks up)

  Did it but probably didn't need to.
