{{NOTE|This is based on the x86-64 version of Fedora 16 with the default GNOME desktop. Your experience with the 32bit version and/or KDE may be different.}}
{{HELP|Not all models of this ThinkPad are equal, you may have a different WiFi adapter or graphics, or some options I did not have. If you tested them, please add their status down below.}}

== New in this release ==
New in this Fedora release, with regards to this model ThinkPad is the following;
* Better out of the box support for Undock
* Better video performance for Intel graphics

Regressions;
* Intel WiFi (iwlwifi) is unstable after suspend, fixed in 3.2 kernel from the Updates repo
* Harmless Intel DRM error messages in log ([drm:ironlake_update_pch_refclk] *ERROR* enabling SSC on PCH), fixed in 3.2 kernel from the Updates repo

== Success Chart - Out of the box experience ==
The SMOLT profile for the T410 used for testing Fedora 16 is [http://www.smolts.org/client/show/pub_0f45aab4-481d-4f36-83ab-6fb7062c19db here].

= Tested and Verified on Fedora 16 =

Information in this section has been tested and verified using Fedora 16.

== Installation ==

Installation is straight forward; you can follow the generic Fedora install instructions. 

== Configuration ==

=== Kernel ===
You may want to consider editing {{path|/etc/default/grub}} and adding {{bootparm|pcie_aspm|force}} to the GRUB_CMDLINE_LINUX line, and running {{cmdroot|grub2-mkconfig}}. This will force enable PCIe ASPM power saving functions, which are getting disabled because the BIOS claims not to support it, but it does work and it makes a significant difference in battery life. A potential downside is that if the system really does not support it, you could experience system freezes, but I have not noticed any (YMMV). This issue is resolved in the upstream 3.3 kernel release.

Likewise you may also want to add the option {{bootparm|i915.i915_enable_rc6|1}} which will allow the Integrated (Intel) graphics to enter a lower power state, and save yet some more power. Again this could cause problems on certain implementations, but I have not noticed any negative effects.

The kernel does log one error message on this ThinkPad, regardless of the above parameters;

''[drm:intel_dsm_pci_probe] *ERROR* failed to get supported _DSM functions''

This error seems to be a BIOS bug that Lenovo has so far failed to fix. It does not cause any problems so the warning can be ignored. However, printing the error does cause a modeswitch during boot which breaks the seamless graphical boot.

=== X Server - Intel HD Graphics===
Works out of the box.

Instructions for locating the correct colour profile for your ThinkPad LCD can be found on the [[Colour profile]] page.

External VGA and DVI (through a Dock) displays work, DisplayPort has not yet been tested.

=== X Server - NVidia===
?

=== ThinkPad Extra keys ===
ThinkPad keys are handled by a mixture of the thinkpad_acpi, acpi button, acpi dock and acpi video drivers.

=== Ultrabay ===

The Ultrabay has some glitches out of the box with respect to hotswapping.  It is possible to lock the machine when pulling out devices, even the CD/DVD device.

The culprit is that the Ultrabay pre-eject switch is not hooked into anything useful.  It does cause udev events, but nothing is listening for them.  When a device that has a mounted partition or CD is actually pulled out it is too late to do the right thing.  linux will usually just complain, sometimes bitterly, but may also lock up for some unknown reason, even if just pulling out a CD/DVD device with a mounted CD.

Manually unmounting before removal will help.  Manual powering down may also be required for correct performance.  

A better solution is to set up a udev rule and script to handle the pre-eject switch event for Ultrabay devices that have mountable things in them as in [[How to hotswap Ultrabay devices]].
