Linux SuSE 6.4 on Notebook:
IBM ThinkPad A20p Model 2629-6SG

This document provides a description of the installation and configuration of Linux SuSE 6.4 on an IBM ThinkPad A20p notebook computer. It can serve as a guide for setting up your own A20p system, a reference for setting up aspects of other machines with similar hardware.

1. Contents

2. Introduction

The ThinkPad as I ordered it came with the following specifications:

3. Installation

 If you have more hints, write me  !

The ThinkPad came with Windows98SE installed, and though I tend towards the extreme side of Linux zealotry I decided to leave the beast installed for the time being so I could watch DVD's and use the Hibernation. For all Partitioning issuses i dicided to use PartitionMagic 5.0x from DOS. So I shrank the Windows partition down:

I then installed SuSE 6.4 from CDROM. The installation must be done manualy. Enter while see first SuSE screen "manual". Do not use "Install lilo or Kernel on floppy"!

There is in an error to access the floppy (also after booting from it!). I'm  unable to read / write or mount data to/from the Floppy! (If you have the same Error, please contact me!)


Installation of PCMCIA Drivers done (autodetect) and running. (Except running with loadlin from WIN98! Then you will not be able to load the PCMCIA Module!)

5. Xwindows

The A20p uses the ATI Mobility 128 AGP video card. Support for the ATI Mobility 128 cards is *NOT*  included in XFree86 as of version 3.3.6, and support is *NOT* available in binary distribution of  Xfree86 4.0. However, if you run XF86Setup or SAX , it`s unable to find a apropriate card.

FrameBuffer Support solution (XFree86 3.3.6)
To running X (very slow) i had to enable Framebuffer support.  To use the FrameBuffer support, you haver to install the framebuffer server from the first cdrom of the SuSE set. Do "rpm -i /cdrom/suse/xsrv2/*.rpm". Use kernel option "vga=834" (1400x1050x16) in /etc/lilo.conf. Configure the X server with "xf86config" (type anything, we do not need this config, but do not probe X!) and replace the /etc/XF86Config file by this XF86Config. After this, you have to replace the link to the XServer. Just do "rm /var/X11R6/bin/X ; ln -sf /usr/X11R6/bin/XF86_FBDev X".
using sax to configure X: Use kernel option "vga=834" (1400x1050x16) in /etc/lilo.conf. Reboot. Start X configuration with the following command: "sax -s XF86_FBDev". Follow the instructions. HSYNC and VSYNC set to "100". After this config start X with startx.

Accelerated r128 FB solution (XFree86 4.0.1)
To get fast accelerated FB support of your A20p  (1400x1050) see Joseph Lingevitch's Page for helpfull tips. It's working, and realy fast. uuhhh!
Here is the XF86Config file, to get 1400x1050x16 with vga=834 in lilo.conf! Or 1400x1050x24 with vga=835 in lilo.conf! Use Binary-Distribution of official XFree86 4.0.1 release.

6. Sound

The A20p comes with a Crystal SoundFusion PCI soundcard. The card will be detected correctly by yast2. First you must disable "PCI Bus Power Mgmt" in BIOS menu. Push [F1] at startup, and disable <Config> - <Power> - <PCI Bus Power Management> (last entry, scroll down!). Otherwise you are unable to play files using PCM.
Startx and go to yast2. Launch the module sound and the card will be detected correctly.

7. Modem

Tha A20p includes a Xircom Modem MPCICard with PartNO: MPCI3A56GSP-100PA. This device works great with the Lucent WinModemDriver. Just download the file, unpack with unzip and start ./ltinst. If its not able to find the devicelink, remove the module by ./ltuninst and redo ./ltinst. You have to do the following, to get modem ready at startup: "ln -sf /etc/rc.d/rc.local /etc/rc.d/rc2.d/S31ltmodem" and "ln -sf /etc/rc.d/rc.local /etc/rc.d/rc3.d/S31ltmodem".

8. USB

I have not yet had a chance to test the USB port, as I have no USB devices. If anyone has info on this, let me know and I'll update this site.

9. APM

Apm is giving a correct load of my battery. apm -s working very well. For wakeup use [Fn] and when see garbage on the screen just move the mouse a little bit, and the desktop is ready again! Check to use the Kernel with APM included.
Hibarnation with running X-Server will result in unusable X-Desktop after resume!

10. Intel Ethernet Pro/100+ MiniPCI

The kernel and the module for Intel Pro/100+ working ok (Module eepro100 autodetected!).
