Installing Fedora 15 on a ThinkPad T410
New in this release
New in this Fedora release, with regards to this model ThinkPad is the following;
- Gnome3 which you either love or HATE.
- Improved support for the Intel HD graphics
- Fn-F6 (Conference key) can now be associated
- Changes made with gpointing-device-settings are not persistent
- Increased power consumption because ASPM is being turned off (see below in the kernel section for a workaround)
Success Chart - Out of the box experience
The SMOLT profile for the T410 used for testing Fedora 15 is here.
|Installation||Local CD/DVD install||yes|
|Display - Intel HD Graphics||Laptop Screen||yes|
|DVI||yes||Requires a dock or Displayport to DVI adapter|
|Display - NVidia||Laptop Screen||unknown|
|DVI||unknown||Requires a dock or Displayport to DVI adapter|
|Power Management||Software Suspend (hibernate)||yes|
|Suspend to Memory (ACPI sleep)||yes|
|Wireless||WiFi - Intel 6200||yes|
|WiFi - Intel 6300||yes|
|WiFi - Realtek||unknown|
|WWAN with GPS||unknown|
|TrackPoint||yes||Install gpointing-device-settings rpm for full configuration capabilities|
|TouchPad||yes||Install gpointing-device-settings rpm for full configuration capabilities|
|Extra keys||partial||see ThinkPad Extra keys section below|
|Modem||no||Should work with the binary Conexant HSF modem drivers.|
|5-in-1 MultiCard Reader||partial||Reads SD and SDHC, but not MemoryStick|
|Harddisk Active Protection||no||Fedora ships the hdapsd rpm, but not the tp_smapi kernel module, which is required to read the motion sensor bugzilla|
|Ultrabay device hotswap||partial||see below, use with caution out of the box|
|TPM||yes||tpm_tis is automatically loaded. After installing the tpm-tools rpm, and starting the tcsd service, the tpm_* commands seem to work.|
|Docking||partial||Dock/Undock works, but since Series 3 docks are not docks but port-replicators there is no true dock/undock handling. They do however cause KEY events on dock/undock, but those are currently not exposed by the thinkpad-acpi driver. This issue is fixed upstream in the 3.0 kernel, and has been made available through Updates as the 2.6.40 kernel (=3.0 in disguise)|
Tested and Verified on Fedora 15
Information in this section has been tested and verified using Fedora 15.
Installation is straight forward; you can follow the generic Fedora install instructions.
You may want to consider editing /boot/grub/grub.conf and adding
pcie_aspm=force to the kernel line. 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).
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.
|wireless||thinkpad_acpi||HAL||partial||Works as a radio kill switch, kills WiFi but not Bluetooth|
|video conference||thinkpad_acpi||HAL||partial||No default action, but can be associated in the Gnome keyboard settings|
|mouse input select||thinkpad_acpi||yes||yes|
|brightness up||acpi video||HAL||yes||includes on-screen display of brightness level|
|brightness down||acpi video||HAL||yes||includes on-screen display of brightness level|
|zoom||thinkpad_acpi||HAL||no||Known Xorg limitation, scheduled to be fixed with the new XKB2 extension, whenever that may be.|
|Vendor key||thinkpad_acpi||HAL||partial||No default action, but can be associated in the Gnome keyboard settings|
|NextTab||Browser Next tab||standard keyboard driver||HAL||yes|
|PreviousTab||Browser Previous tab||standard keyboard driver||HAL||yes|
|Up||Stop||standard keyboard driver||HAL||yes|
|Left||reverse||standard keyboard driver||HAL||yes|
|Right||forward||standard keyboard driver||HAL||yes|
|Down||play/pause||standard keyboard driver||HAL||yes|
|Power||Power button||acpi button||HAL||yes||Need to press button for ~1 second to trigger a Suspend event.|
|Lid||Lid button||acpi button||HAL||yes||Triggers suspend event|
|Dock||Dock eject||-||yes||yes||works, but the KEY events are not passed to userspace so you cannot use it to do custom actions. Also check out this page for some potential issues and workarounds. The HKEY event issue is fixed upstream in the 3.0 kernel, and made available in Fedora 15 Updates in the 2.6.40 kernel (which is 3.0 in disguise).|
|Ultrabay||Ultrabay eject switch||acpi dock||udev||no||Missing handler, see Ultrabay instructions below|
|Radio switch||Radio kill switch||thinkpad_acpi||udev||yes|
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.
