Installing Gentoo on a ThinkPad R51-1830
This page shows some partes of how I did once install Gentoo Linux on my ThinkPad. Since the R51 is now quite outdated (2005) everyone having such a laptop surely has his/her system installed already. So why this page?
Mainly out of interest and for fun.
If you also own a Thinkpad R51 (machine types 1829, 1830, 1831 and 1836) feel free to add what you think is missing.
My system specs
- Pentium M 1.7 GHz
- 1.5 GB PC2700 DDR RAM (I upgraded by 1 GB)
- 100 GB Western Digital HDD (upgraded, not original)

Preparing for Installation
The laptop originally came with an 80 GB Hitachi hard disk.
TpUser0@localhost # fdisk -l /dev/hdc Disk /dev/hdc: 80.0 GB, 80026361856 bytes 240 heads, 63 sectors/track, 10337 cylinders Units = cylinders of 15120 * 512 = 7741440 bytes Device Boot Start End Blocks Id System /dev/hdc1 * 1 9736 73604128+ c W95 FAT32 (LBA) /dev/hdc2 9737 10337 4543560 12 Compaq Diagnostics
When I received the ThinkPad I did not switch it on right away! I did also not start Windows XP!
A cronological list of what I did:
- Since I had a 2.5 inch IDE adaptor I removed the HDD from the ThinkPad and put it in my desktop computer.
Use a Knoppix Live Linux (or any other Live Linux) on CD/DVD if you don't have an adaptor.
- I made a backup of each parition. Back in 2005 I used
Use a program of you choice or even
ddif you prefer, but keep in mind that it should also work if you change the parition sizes and positions.
- I resized the Windows partition from its almost 75 GB to 20 GB using
- I made an image of the resulting partition too.
- I deleted the second partition which is the rescue partition. Since I now had my own rescue images I didn't need it anymore.
You will have to turn of the "Rescue Parition" feature in the BIOS to do this!
- I then booted into Windows XP for the first time (!) and set it up to suit my needs.
My system always converts FAT32 to NTFS and installs all the programs that came with the ThinkPad. I then need to install Service Pack 2 and all other recent updates for Windows and all the other programs. Use the Software Installer from IBM (Lenovo) to do this for you. You will need a broadband internet connection though, or you have all the files at hand (offline update). Another partition image of a recent and updated configuration will save your time for future Windows XP recoveries.
- I then partitioned the rest of the hard disk with Linux and installed Gentoo Linux according to the manual.
In my case I just copied an existing installation from my desktop to the ThinkPad and re-emerged everything with the correct CFLAGS and USE flags.
My partition layout (after I upgraded to a 100 GB hard disk):
tpuser0@localhost # fdisk -l /dev/hda Disk /dev/hda: 100.0 GB, 100030242816 bytes 240 heads, 63 sectors/track, 12921 cylinders Units = cylinders of 15120 * 512 = 7741440 bytes Device Boot Start End Blocks Id System /dev/hda1 1 2774 20971408+ 7 HPFS/NTFS /dev/hda2 * 2775 2779 37800 83 Linux /dev/hda3 2780 12921 76673520 5 Extended /dev/hda5 2780 5943 23919808+ 83 Linux /dev/hda6 5944 12726 51279448+ 83 Linux /dev/hda7 12727 12921 1474168+ 82 Linux swap / Solaris
As you can see I have
|device||mount point||description and notes|
|/dev/hda1||/mnt/windows|| 20 GB reserved for the Windows XP installation |
I bought it with the laptop, so why not use it from time to time?
|/dev/hda2||/boot||40 MB for the kernels...|
|/dev/hda5||/|| 25 GB for the root directory |
I figured it be best to have no seperate partitions for / and /usr...
|/dev/hda6||/home||53 GB for all my personal files (and I have a lot of them!)|
|/dev/hda7||swap|| 1.5 MB |
You need at least the size of RAM you have in your system for swap or hibernation will not be possible.
Base configuration (Gentoo)
- #=== hardware ===
- ALSA_CARDS="intel8x0 intel8x0m virmidi dummy" – add "usb-audio" if you have additional devices such as TV capture cards.
- VIDEO_CARDS="radeon fbdev dummy vesa" – add "fglrx" for the proprietary driver from ATI.
- INPUT_DEVICES="keyboard joystick mouse synaptics"
- SANE_BACKENDS="genesys" – if you have a scanner, add your SANE backend here.
- #=== host settings optimizations ===
- CFLAGS="-O2 -march=pentium-m -fomit-frame-pointer -pipe" – I'm using very stable settings here because I want to work with my laptop, not tune it for crashing all the time...
- #=== portage ===
- Most of the other settings are explaned in
/etc/make.conf.example– don't forget to add them too!
- SYNC="rsync://rsync.de.gentoo.org/gentoo-portage" – use
- FEATURES="sandbox ccache parallel-fetch userfetch userpriv usersandbox"
- USE=" your USE flags here " – use
ufed(Use Flag EDitior)
Install X11 (I use XOrg X11):
tpuser0@localhost # echo VIDEO_CARDS="radeon" >> /etc/make.conf tpuser0@localhost # emerge x11-base/xorg-x11
Prepare /etc/X11/xorg.conf: make sure you load the necessary X11 modules:
# a piece of /etc/X11/xorg.conf Section "Module" Load "GLcore" Load "dri" Load "glx" EndSection
Prepare /etc/X11/xorg.conf: create a dri group and restrict access to the DRI driver for users in that group (replace “408” by the group id of your dri group):
# a piece of /etc/X11/xorg.conf Section "DRI" Group 408 # group "dri", next available id 408 Mode 0660 EndSection
Prepare /etc/X11/xorg.conf: the 15″ TFT flat panel:
# a piece of /etc/X11/xorg.conf Section "Monitor" Identifier "Monitor1" VendorName "IBM" ModelName "LCD Panel ThinkPad R51" Option "dpms" EndSection
Prepare /etc/X11/xorg.conf: finally, the xorg-x11 radeon driver:
# a piece of /etc/X11/xorg.conf Section "Device" # ATI Radeon R250 (ATI Radeon Mobility 9000 M9) Identifier "ati-xorg" Driver "radeon" BusID "PCI:1:0:0" Option "DynamicClocks" "true" Option "RenderAccel" "true" Option "EnablePageFlip" "true" Option "BackingStore" "true" EndSection
For more performance in X11 I also played with some additional parameters in /etc/X11/xorg.con, with various effects:
# a piece of /etc/X11/xorg.conf Section "Device" # ATI Radeon R250 (ATI Radeon Mobility 9000 M9) Identifier "ati-xorg" Driver "radeon" BusID "PCI:1:0:0" # ALWAYS "ON" OPTIONS Option "DynamicClocks" "true" Option "RenderAccel" "true" # ENCOURAGED OPTIONS Option "EnablePageFlip" "true" Option "BackingStore" "true" # "PLAY WITH" OPTIONS FOR TUNING PURPOSES #Option "AGPFastWrite" "on" # ERROR: mplayer/xine/... xv (xvideo) modules don't work anymore! #Option "DDCMode" "true" # use DDC (monitor) data to calculate mode lines #Option "AccelDFS" "on" # (disabled by default for AGP due possible problems) #Option "FBTexPercent" "0" # with EXA: (set to 0: reserve all offscreen RAM for EXA, OpenGL textures only in GART memory) # CRASH options: #Option "AGPMode" "2" # CRASH! (with or without AGPFastWrite) #Option "AGPFastWrite" "on" # CRASH! (with AGPMode "2") # SLOW options: #Option "AccelMethod" "EXA" # newer and faster (!?) acceleration method EndSection
