## Video drivers

Users have the choice between the open source [ATI](/index.php/ATI "ATI") video driver or the closed source [Catalyst](/index.php/Catalyst "Catalyst") video driver.

As of 3.15 kernel, the open source drivers are very suitable for this chips' GPU. 3.16 is a mild improvement over that.

The HD8330 video device on this laptop is part of the Sea Islands family (Kabini chipset) of AMD GPUs. As the new [AMDGPU](/index.php/AMDGPU "AMDGPU") kernel driver is now needed as of Linux kernel 4.13 for GL support, adding `amdgpu.cik_support=1 radeon.cik_support=0` kernel parameters is required to boot with full OpenGL support.

## Wireless

The Thinkpad x140e is available from Lenovo with one of two wireless cards:

*   A BGN solution of unknown chipset.
*   A Broadcom ABGN Wifi / BT4.0 card which is currently not supported by the `b43` driver. Ideally, use driver `broadcom-wl`. See [Broadcom wireless](/index.php/Broadcom_wireless "Broadcom wireless") for details.

As of BIOS 2.05, the X140e supports Lenovo branded mPCIe Intel 802.11 ac/a/b/g/n. However no X140e is currently sold with this wifi option. This card is supported out of the box by Arch. The only tested and confirmed FRU is 04W3814.
