My thinkpad
IBM ThinkPad X31 (2673-CBU), bought used.
Currently running: Kubuntu 5.10 (Breezy).

Installation issues
I first installed Kubuntu 5.10 (Breezy). I wanted to keep Windoze, just in case I needed it (but I never use it ;) ), and keep the hidden protected area, and be able to reach it at startup, just in case I sell the laptop back at some point. My problem was that:
- GRUB has to be installed either in the MBR or in the first partition. At least that's what I thought at the time but it's probably wrong, see here. Anyway, I wanted to keep Linux in front, as I plan to remove windoze completely, and the first part of the disk should be faster.
- Windows would only work being on the first partition (AFAIK)
- Putting GRUB in the MBR would overwrite the original setup/recovery tools (AFAIK - Note: if you do this, and later manage to start Windows, it will rewrite the MBR anyway)
My solution (DO IT AT YOUR OWN RISK):
- Create a new primary partition for Windows, at the end of the disk, before the rescue partition. Copy windows there.
- Modify windows' boot.ini:
$ diff /windows/boot.ini /windows/boot.ini~
3c3 < default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS --- > default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS 5c5 < multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /fastdetect --- > multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
My current partition table according to fdisk:
Disk /dev/hda: 36.8 GB, 36825459200 bytes 255 heads, 63 sectors/track, 4477 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 6 48163+ 83 Linux /dev/hda2 3651 4477 6642877+ b W95 FAT32 /dev/hda3 7 249 1951897+ 82 Linux swap / Solaris /dev/hda4 250 3650 27318532+ 5 Extended /dev/hda5 250 3650 27318501 83 Linux Partition table entries are not in disk order
Post-install configuration
- (I think I) modified interfaces to enable hotplugging the ethernet cable. Which is wrong anyway.
- I enabled Fn + F5 creating file /etc/modprobe.d/ibm_acpi.modprobe with the following line:
options ibm_acpi hotkey=enable,0xff9f
- Modified my GRUB menu.lst. The Fn + F5 stopped working.. Finally I found out why looking at /usr/src/linux-source-2.6.12/Documentation/networking/README.ipw2100 in section rf_kill, and modified /etc/acpi/wireless.sh accordingly, see here. All this should revert to normal without passing options to ipw2100.
Configuration files
- xorg.conf
- interfaces
- GRUB's menu.lst
- Windoze boot.ini
Current issues
- How can I switch Fn and Ctrl keys? (I guess I can't as Fn combinations are interpreted by the BIOS)
- Enable scrolling and keep functionality of mouse 2 button. For the moment I'm using button 2 to scroll, and emulating 2=1+3 to paste. See the "InputDevice" section in my xorg.conf
- Wireless:NOT A PROBLEM (see below) At the moment I can do:
# iwconfig eth0 essid <name> key <key>
and it seems to work fine, but no tx power:
# iwconfig
eth0 IEEE 802.11b ESSID:"rightname" Nickname:"ipw2100" Mode:Managed Frequency:2.462 GHz Access Point: 00:0F:34:D5:90:E0 Bit Rate=11 Mb/s Tx-Power:off Retry min limit:7 RTS thr:off Fragment thr:off Encryption key:XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XX Security mode:open Power Management:off Link Quality=100/100 Signal level=-58 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:184 Missed beacon:0
but
# iwconfig eth0 txpower on
Error for wireless request "Set Tx Power" (8B26) : SET failed on device eth0 ; Invalid argument.
UPDATE: apparently this is not a problem! I'm using it right now, and I still see TxPower:off so it's just not related.. I'd like to make KWirelessManager aware of this, it still shows it as disabled even though it gives me the correct speed, but as it's working it's not really a problem.. One thing: I added it to my /etc/network/interfaces file and ifup'd it manually
- FnF7 does not work
- Hissing sound when on batteries. This is only audible in a very silent room, where a plug is normally available anyway, so I guess I will keep it like this..
- Untested:
- Irda
- modem
- IEEE 1394
- Parallel port
