### UEFI

The G750 is a UEFI device, but can also boot from a partition with the "boot" flag set in the traditional manner. Both UEFI and legacy boot methods work with syslinux using the instructions on the wiki here.

### Graphics

Works fine with nvidia from the official repositories. The xf86-video-nouveau driver has not yet been tested.

#### HDMI port

HDMI video output works using the proprietary video driver. HDMI audio output works using pulseaudio.

#### VGA port

Works using the proprietary video driver.

#### DisplayPort over Thunderbolt port

Works using the proprietary video driver.

### Touchpad

Does not quite work out-of-the-box with xf86-input-synaptics from the official repositories. The touchpad is mistakenly recognized as a click-pad, leading to the right mouse button being disabled and some other strange behaviour. A fix to enable the right physical button is available here.

UPDATE 2014-04-01 - The above has been fixed in kernel 3.13.8 (Input: elantech - improve clickpad detection). Physical right touchpad button now confirmed working on a G750JX.

To remedy the other strange behaviour (a left-click is interpreted as a right-click if a finger is touching the lower-right area of the touchpad), the following options are required:

    /etc/X11/xorg.conf.d/50-synaptics.conf

            Option "SoftButtonAreas" "0 0 0 0 0 0 0 0"
            Option "RTCornerButton" "0" #right-click to bottom right

### USB 3

All USB ports work fine with no configuration required.

### Optical drive

Can read from and write to CD/DVD media with no configuration required. BD-ROM reading has not yet been tested.

### Sound

The integrated stero microphones work out-of-the-box with PulseAudio. The headphone and microphone ports also behave as expected. To get the bass speaker working, it is necessary to enable 2.1 sound in PulseAudio:

    /etc/pulse/daemon.conf

            default-sample-channels = 3
            enable-lfe-remixing = yes

alsamixer from alsa-utils maps the bass speaker to the "Speaker" channel, and maps the left and right speakers to the "Headphone" channel. PulseAudio jack detection can interfere with this configuration; to disable it, comment out this line:

    /etc/pulse/default.pa

            # load-module module-switch-on-port-available

### Webcam

Works fine with no configuration required. The webcam records at a higher framerate than the sensor on the G73 and is actually usable, but it isn't anything special.

### SD card reader

Works fine with no configuration required. Note that the G750 is unable to boot from the card reader, even in legacy mode.

### Networking

#### LAN

Works fine with no configuration required.

#### WLAN

Works fine with no configuration required.

#### Bluetooth

Works fine using bluez with no configuration required.

### Untested

- Data transfer over Thunderbolt port
- BD-ROM reading
