Configuration

BIOS

2.20.1271

At bootup, the BIOS settings page is entered via the delete key, the quick boot select window can be activated via the F11 key, PXE scanning can be activated via the F12 key

In the BIOS setings, the model name can be seen in the Main tab, Secure Boot can be disabled from the Security tab and boot mode can optionally be switched from UEFI to legacy. Advanced BIOS options can be accessed by going to the 'Advanced' tab and holding down l-alt, then pressing r-ctrl, r-shift, then F2.

There is no known option to disable the discrete intel GPU, there may be one present after unlocking the advanced options.

E16Q2IMS.110

This BIOS version introduces many ACPI problems (if BIOS is changed from UEFI to legacy), including a flood of "No handler or method for GPE [00->6E]" at boot, which can be solved through kernel parameters:

  • acpi=off allows to boot but most things won't work, including the keyboard and touchpad.
  • pci=nomsi or acpi=off acpi=force allows to boot and have working keyboard and touchpad, but the NVidia card won't work ; neither will the USB3 ports.
  • pcie_aspm=off will allow most things to work: keyboard, touchpad, USB 3 devices, NVidia card.

Video

Backlight

Backlight works out of the box

# ls /sys/class/backlight/
intel_backlight

Drivers

PRIME functionality works by using only nvidia and will work without the intel video driver, instead using modsetting.

The xf86-video-nouveau driver does not work well in PRIME configuration (see #Known Issues}).

Multihead

Multihead support works with intel-virtual-output tool, following the 'port wired to Nvidia' instructions at Bumblebee and using this post at Stack Exchange.

Thunderbolt port is wired to Intel GPU thus allowing for external monitor to be used with nvidia gpu off.

Webcam

The webcam is device 003 on bus 001. See Webcam setup for more details.

Power Management

Battery indicator works out of the box.

Sleep and wake also work with the proper configuration (see Power management).

An issue when sleeping is that the networking will be disabled when waking and set to airplane mode. This issue does not affect hibernation.

The Steel Series lights on the keyboard cannot be configured with msi-keyboard-gitAUR or msiklm-gitAUR, because those tools only work with region-based RGB lighting. For this laptop model, the tool msi-perkeyrgbAUR provides partial control.


$ msi-perkeyrgb -m gs65 --list-preset
Available presets for GS65:
	- aqua
	- chakra
	- default
	- disco
	- drain
	- freeway
	- plain
	- rainbow-split
	- roulette
$ msi-perkeyrgb -m gs65 -p aqua

If keyboard lights remain off, be sure you've rebooted after installing msi-perkeyrgb to refresh udev and that the brightness is turned to maximum with Fn+PgUp, then try the command again.

Button Mapping

Airplane Mode Key Combination

The airplane mode key combination (FN + F10) is disabled by default. Adding the following kernel parameters activates airplane mode key combination:

acpi_osi=! acpi_osi="Windows 2009"

Unmapped Buttons

The following buttons don't have any function or keycodes.

  • FN + F7
  • FN + Home

Non-US Keyboards' Backslash/Pipe 102nd Key

Warning: As of Feb 2019, systemd 241.7 reverted this change; this workaround is no longer required.

Systemd v240 addressed an issue for US keyboards which broke the mapping for the 102nd key on non-US keyboards. This is the key on the right of the space bar. For a UK keyboard it is the backslash/pipe key and you can correct the scancode to keycode mapping with # setkeycodes 56 86 . To make this permanent, save the command to an executable shell script with a #!/bin/sh shebang, then create and enable the following systemd unit file:

[Unit]
Description=Remap backslash key
[Service]
Type=oneshot
ExecStart=/path/to/shell/script
[Install]
WantedBy=multi-user.target

Touchpad

Single tap and double finger scrolling work. Multi gestures do not work out the box though, they are detected with libinput-gesturesAUR.

Troubleshooting

Webcam is not detected

If /dev/video0 is unavailable and lsusb does not list the webcam, make sure that hard webcam switch is activated. The switch is indicated on the F6 key and can be toggled with FN + F6.

Tips and Tricks

Microphone noise reduction

GS65 has the twin microphone, which is very cool to have for noise reduction and echo cancellation, as well as background sounds suppression via beamforming technique. To get the best of it add this line to /etc/pulse/default.pa:

load-module module-echo-cancel use_master_format=1 aec_method=webrtc aec_args="beamforming=1 mic_geometry=-0.025,0,0,0.025,0,0"
set-default-source alsa_input.pci-0000_00_1f.3.analog-stereo.echo-cancel

Also, it could be useful to add analog_gain_control=0 to aec_args to disable automatic gain control.

Known Issues

Lockup Issue (lspci and poweroff hang)

Symptoms:

  • lspci hangs
  • poweroff hangs

Applies to: Arch boot ISO and systems with nouveau or without nvidia driver installed. See NVIDIA Optimus#Lockup issue (lspci hangs).

Solutions:

Cheese Hangs While Opening Camera

The issue can be fixed by installing vlc and running:

$ vlc v4l:// :v4l-vdev="/dev/video0"

Following this, cheese should work correctly.

Wifi is hardblocked (airplane mode) after waking up from suspend

Waking from suspend will have wifi in airplane mode. [1]

# rfkill list
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: yes

Wifi can be reactivated by either using the airplane mode key combination twice or by hibernating and rebooting.

A way to mitigate this is by setting systemd to hibernate instead of suspending.

/etc/systemd/logind.conf
HandleSuspendKey=hibernate
HandleLidSwitch=hibernate

System freeze

From time to time the graphical interface will freeze and the keyboard will be unresponsive, though audio keeps running. It tends to happen when CPU temperature is high and CPUs are throttling.

There is no known solution for this.

It is not clear what causes this issue:

$ journalctl -r --boot -1 
Jul 22 20:27:40 almsi kernel: nvidia-modeset: ERROR: GPU:0: Failed to allocate memory for the display color lookup table.


Display outputs don't work after suspend

If the laptop is suspended with another monitor connected, then on wake all display outputs do not recognise when an external display is connected to any port. This persists across reboots. Worryingly it also persists if you reboot into Windows.

One workaround is to boot into Windows, suspend the laptop, then wake it. Connected displays will then be recognised when rebooting into Windows or Arch.
