==== Linux ====
Most of the laptop features are currently supported by Linux. Kernel versions 2.6.17 and later are recommended.

==== Hardware support ====
===== Sound =====
Sound works with the snd-hda-intel module in the Linux kernel. Be aware that '''disabling the modem''' in the BIOS may '''break''' sound.

===== Fan control in EC =====
Apparently with latest BIOS (maybe earlier too), Embedded Controller do not speed up the fan when system temperature is high. This function seem to

It is recommended to install [http://www.thinkwiki.org/wiki/How_to_control_fan_speed#Automated_control_scripts script controlling fan speed] to mitigate risk of overheating.

===== Virtualization =====
[[Intel Core Duo (Yonah)]] and [[Intel Core 2 Duo (Merom)]] supports Intel VT-x. However, earlier versions of the Z61t BIOS [http://forum.thinkpads.com/viewtopic.php?t=31049 disable it]. You must update your system's BIOS to Version 7FETA0WW (2.18) or later to take advantage of virtualization. Also, you must enter the BIOS configuration menus and explicitly enable the feature.

See the [[BIOS_Upgrade|BIOS Upgrade]] page for details on updating your BIOS.

===== IRDA =====
Make sure you either explicitly enable or disable the IRDA functionality in the BIOS (instead of having it be enabled but off). Otherwise the kernel IRDA driver will OOPS. Other than that it works fine.

===== Graphics =====
Requires xorg-x11 >= 7.1<br>
xf86-video-i810(xorg i810 driver) >= 1.7.0<br>
915resolution.

For Ubuntu Gusty (7.1) Distribution
Intel 945GM chipset works right out of the installation.
The driver is Intel Experimental Modesetting Driver

===== 3-in-1 card reader =====
Support for the built-in memory card reader is provided by the [[tifm]] drivers.

===== ACPI =====
====== Suspend ======
As of kernel 2.6.17, suspend works, with the caveat that the SATA controller is set to compatibility mode in the BIOS (instead of AHCI mode). This is due to the fact that the kernel dosen't exactly support suspend/resume in the AHCI driver yet, and the AHCI module fails to turn the hard drives back on at resume time.

Patches for AHCI suspend are aviable at the following urls:
[http://marc.theaimsgroup.com/?l=linux-ide&m=114958999517565&w=2 Description]
[http://marc.theaimsgroup.com/?l=linux-ide&m=114958968123198&w=2 Patch 1]
[http://marc.theaimsgroup.com/?l=linux-ide&m=114958999523165&w=2 Patch 2]
[http://marc.theaimsgroup.com/?l=linux-ide&m=114959199902868&w=2 Patch 3]
[http://marc.theaimsgroup.com/?l=linux-ide&m=114959199906103&w=2 Patch 4]
[http://marc.theaimsgroup.com/?l=linux-ide&m=114958984425832&w=2 Patch 5]
[http://marc.theaimsgroup.com/?l=linux-ide&m=114958984425521&w=2 Patch 6]

For Ubuntu 7.1 Distro,
suspend with SATA in AHCI mode works fine.

====== Problems with Drivers ======
Certain driver modules are known to exhibit problems on suspend. These are:
* ipw3945: Intel wireless driver.
* sdhci: SD host controller interface driver.
* [[tifm]]: Memory card reader driver.
Depending on which combination of kernel and driver versions you're using, the above drivers may cause you problems. These drivers should be unloaded prior to suspend or your system may hang, requiring a power-cycle.

For Ubuntu 7.1
suspend resumes fine for ipw3945 and sdhci driver. Unsure about tifm driver.
However, tracker (indexing) program use higher than expected cpu resource after resume.
Disable tracker fixes this issue.
