Kubuntu 9.10 installation notes on a ThinkPad X100e

Bluetooth

By default, the X100e ships with bluetooth disabled or not installed. There is no option for it in the BIOS; currently the only way to enable it is to install Hotkey Features Integration [1] in Windows, and then press Fn-F5 to bring up the wireless control panel.

Audio Jack

By default the audio jack doesn't disable the internal speakers in Linux, in fact it doesn't seem to work at all (at least in Ubuntu 10.04 -- apparently in Mint it works for some people). A workaround for this is to edit /etc/modprobe.d/alsa-base.conf and add the following line: options snd-hda-intel model=olpc-xo-1_5 and then restart alsa (or reboot).

As of the 2.6.34 kernel [2] the above workaround should no longer be needed.

Wireless b/g/n

In many distros, Ubuntu included, the r8192se module that ships with the kernel will load and successfully connect to an AP and even succeed with DHCP, but still pass no network traffic. A workaround is to get the latest driver code from realtek [3], unpack it and do a 'make' (assuming you have the equivalent of build-essentials installed) and then from the build directory, copy ./HAL/rtl8192/r8192se_pci.ko over top of e.g. /lib/modules/$(uname -r)/kernel/ubuntu/rtl8192se/r8192se_pci.ko (will vary depending on distro) and then reload the module/your wireless manager/etc.

Note: as of kernel 2.6.32-22.33 wireless should work out of the box (the latest kernel on Ubuntu Lynx has these updates). Neither the Realtek provided drivers or the staging drivers support injection at this time.

The Intel Wifi Link 5100 (AGN) half height card from the T400/T400s works without a BIOS error on the X100e. Injection works with the 5100, see the Aircrack documentation[4]. Please note that if you try and order the card off of eBay, you must find one that came out of a Thinkpad - the laptop will not boot if you use a generic one.

Hangs on changing brightness and switching power modes

Some x100e's will hang when you unplug the power, or change the brightness in X. To solve this, upgrade to the latest BIOS and optionally install the proprietary FGLRX drivers. I updated the bios like this: BIOS_Upgrade/X_Series#Approach_10:_Booting_the_Lenovo_ISO_image_using_Grub_and_SysLinux

Under kernel 2.6.35-rc4 (and possibly 2.6.34), the open source Radeon drivers work properly with brightness controls, and don't have the same negative effects with compiz that the FGLRX drivers do.

ACPI and Special Key Support

As of 2.6.35-rc4, ACPI support for the X100 has improved. It's no longer considered an "unknown thinkpad model", and no patching is required. Most of the "special keys" (fn + Fkey) generate an acpi event, which can be used to trigger an action of your choosing. Use "acpi_listen" to get the code.

Many of the hotkeys worked "out of the box" with Linux Mint and the bleeding edge RC kernel, however the FF/RW/Play buttons appear to do nothing (so far). The disable touchpad special key works, but not consistently.
