Wireless NIC | Works | wl

## Hardware

### Bluetooth adapter

Installing the Broadcom wireless#broadcom-wl driver will not help and the Bluetooth adapter is essentially inoperational.

### GPU

GPU has kernel support and works out of the box.

For X.org drivers, install xf86-video-intel.

### Touchpad

Install xf86-input-synaptics.

Note: linux-lts has no support for FocalTech touchpads and the device will remain in mouse emulation mode.

### Wireless NIC

See Broadcom wireless#broadcom-wl.

Warning: Version 6.30.223.248 is unstable with linux in the interim, consider downgrading to linux-lts. Enabling the monitor mode causes a lockup as does somewhat heavy network traffic.
Note: The FLOSS driver `b43` does not support `LCN40` PHYs (as demonstrated that `BCM43142`, the chip this laptop sports, is one here) yet.

## Troubleshooting

### ACPI

#### Laptop freezes when booting Linux

Set the BIOS setting `OS Selection` in the `Advanced` menu to `Windows 7`.

It’s possible to boot into Linux by either disabling ACPI or overriding the DSDT, but some devices might no longer operate.

#### Unable to control screen backlight

Add kernel parameter `video.use_native_backlight=1` to bootloader configuration.
