Ubuntu Linux 7.04 -and probably any modern distro- "just works" out-of-the-box on this machine.
No manual configuration was required. Even network, wifi, xorg (with 3D acceleration), sound and suspend-to-ram were properly configured and functional, all with opensource drivers only, at the end of the default Ubuntu installation. I've no problem with fan noises either.
But there's still some room for fine tuning:
- To improve energy efficiency and battery life (8 cell bat gives 4h with default install, 6h after tuning)
- To access some special features (like some Thinkpad special keys)
- To better use resources (memory, CPU, power, ...)
This an "all Intel" machine: differing from most other Thinkpad models because even the network, wireless and graphic controllers uses Intel chipsets. Note that some X40 models use atheros for wifi, or tg3 for ethernet (but not mine). That's why I opted for this one (beside the 1.2 Kg ultraportable form factor).

- new one : 8 cells, Li-Ion, 4400 mAh (about 63W), 0.4 kg, ref (FRU) : IBM-92P1083 ~5h30
- BIOS version : 1UETD3WW (2.08 ), built on 2006-12-21, released on 2007/01/31
- IBM ThinkPad Embedded Controller version : 1UHTA6WW (1.56)
- FW model : TP-1U
The X40 is a very small ultraportable, and doesn't have builtin CDROM or floppy drive. I own an IBM UltraBase X4 dock station, but her DVDrom is dead. So I went for PXE (network boot) installation for the first time ; I just applied instructions from this web page : this was unexpectedly simple and worked flawlessly. Everything got installed from network, "over the air".
I kept the 4Go IBM recovery partition at the end of the drive, by superstition and for Rescue and Recovery. Afterwards, I compiled my own 2.6.22 kernel, patched with high resolution timers, to improve the battery life, and applied tips from the How to reduce power consumption.
Distribution (Ubuntu Feisty Fawn 7.04)
Even if everything was supported, there was some small things where Ubuntu (or Gnome, or Linux kernel) could have done better:
- Suspend-to-ram works out-of-the-box, no special tricks are needed. But sometimes, not always, for an unknown reason, the Gnome "logout" screen hides the s2ram and s2disk (hibernate) options. Whatever, we still can suspend thanks to the thinkpad's special keys (or just with an "echo mem > /sys/power/state").
- Ubuntu installs the "special keys" handler from the "hotkey-setup" package. This is suboptimal, since hotkey-setup supports less special keys than tpb, and consumes a lot of battery (see for instance this bug report).
- More generally, the whole Ubuntu system needs work to become efficient on laptop: switch to a 2.6.21 or more kernel, use in kernel "ondemand" governor rather than userland powernowd+hald-addon-cpufreq, activate AC97 power saving features when on battery, etc.
- The default Ubuntu install left me with a lot processes related to printing (cupsd, gnome-cups-icon, hpiod, hpssd (this one is a python script!)) while I have no printer configured nor attached. Bad. They shouldn't start this until hald find something plugged or until I try to configure a printer. It also left the bluetooth "hcid" daemon, while I've no bluetooth controller. evolution-alarm-notify is running while I've never launched (let alone configured) Evolution.
Hardware and BIOS limitations
The hardware is fine for me, even if a bit old by nowadays standards (I'd prefer have an Intel AHCI chipset with SATA drive on it, for power efficiency reason, and I'd prefer a Core2Duo CPU....). It lacks also some options available on some other Thinkpads models, like the fingerprint reader (but seriously, I prefer give this up to keep my "all Intel" chipsets). It lacks a Firewire controler. The BIOS is also somehow suboptimal, in some aspects.
For an unknown reason, the BIOS disable by default the deeper power saving c-states (C3 and C4). There's two option for this that you need to turn on, despite the the misleading BIOS online help that says "usualy not needed". Type "F1" during boot to access the BIOS, then enable:
CPU power management PCI bus power management
The BIOS, as in many laptops, hides the HPET hardware timer to the system. Windows XP don't support HPET and when enabled, it displays a yellow exclamation mark on his device manager list, hence the common vendor choice to disable it. That's a bit odd since Linux can make a great use of it: other available timers (PIC/LAPIC) can't schedule timer events more than a few milliseconds away, so they causes about 20 to 40 CPU wakeups per second. This impact the power consumption greatly. Yet, thanks to the Udo A. Steinberg and Venki Pallipadi, we have a way to force enable HPET on chipsets known to support it (this include ICH3-M, ICH4-M, ICH5-M etc.). So I applied their patch, part of the Resolution Timer patchset on top of my hand compiled 2.6.22-rc5 kernel, and all worked fine:
dmesg | grep hpet:
[ 3.740522] hpet clockevent registered [ 3.740527] hpet0: at MMIO 0xfed00000, IRQs 2, 8, 0 [ 3.740532] hpet0: 3 64-bit timers, 14318180 Hz [ 5.080000] Time: hpet clocksource has been installed.
Not tested yet
- TCPA chipset: Trusted Computing controller. Should be supported by tpm and tpmdd but who need this, really ?
- HDAPS (Hard Drive protection mechanism): this should work out of the box, we have a kernel module for that but I disable it because it's known to suck power
- IrDA (Infrared controller) : is known to work too, and looks supported by my kernel, but I've no other IrDA device to test with
- SD Card slot : I've no SD cards to test this
- 56K Modem: I've no use of this

Other Linux installation reports on Thinkpad X40
Don't forget that the X40 line included different ethernet (tg3 or e1000) and wireless (atheros or Intel) chipsets, and that Linux support involved over time. So there may be some difference between your experience with X40 and others reports. Some reports are quite old too, and Linux involve at fast pace.
