ASUS N550JV - this article covers hardware specific configuration. All topics covered can be performed after an installation of Arch Linux has been finished and the machine rebooted into it.
For a general overview of laptop-related articles and recommendations, see Laptop.
Configuration
Video
Drivers
Install bumblebee along with Nvidia and Intel drivers.
Brightness
FN+F5
and FN+F6
will not produce any output (will not work) untill you use the kernel parameter acpi_osi=
to your bootloader. It's indeed followed by a blank space.
Audio
Install PulseAudio.
After installation, reboot the laptop to ensure all modules are loaded. Check if the fallback device is correctly set to Build-in Audio Analog Stereo with pavucontrol. See PulseAudio/Troubleshooting#Fallback device is not respected for more information. Also check for muted devices:
$ alsamixer -c PCH
Keyboard
Brightness
Key mappings FN+F3
and FN+F4
should work with majority of desktop environments out of the box. If not, install asus-kbd-backlightAUR, load kernel module asus-nb-wmi
to control hotkeys, then start and enable the asus-kbd-backlight.service
.
Now you can take control over the keyboard backlight:
$ asus-kbd-backlight up $ asus-kbd-backlight down $ asus-kbd-backlight max $ asus-kbd-backlight off $ asus-kbd-backlight night $ asus-kbd-backlight 2 $ asus-kbd-backlight show
Incorrectly mapped buttons
Media
and FN+F7
buttons are not mapped correctly. It is not necessary to remap FN+F7
shortcut, because it works without any additional configuration.
Install xorg-xmodmap, which provides app xmodmap
. Generate a xmodmap config file if you haven't done it already:
$ xmodmap -pke > ~/.Xmodmap
Then open it and locate keycode 234:
~/.Xmodmap
... keycode 233 = XF86MonBrightnessUp NoSymbol XF86MonBrightnessUp keycode 234 = XF86AudioMedia NoSymbol XF86AudioMedia keycode 235 = XF86Display NoSymbol XF86Display ...
Now move XF86AudioMedia NoSymbol XF86AudioMedia
text on the empty keycode 248 and leave keycode 234 empty:
~/.Xmodmap
... keycode 234 = ... ... ... keycode 247 = keycode 248 = XF86AudioMedia NoSymbol XF86AudioMedia keycode 249 = ...
Optionally, for FN+F7
give some value on keycode 253.
~/.Xmodmap
... keycode 252 = keycode 253 = XF86Launch0 NoSymbol XF86Launch0 keycode 254 = ...
The next step is apply changes:
$ xmodmap ~/.Xmodmap
Test with xev
or try to bind something on media button. FN+F7
should be controlled by hardware and switch display without any additional configuration. Also, if you are satisfied, put the command above to Xinitrc.
~/.xinitrc
{ sleep 10; xmodmap ~/.Xmodmap; } &
Touchpad
Install Touchpad Synaptics driver.
Troubleshooting
Audio
Dual boot
If you boot your laptop right after Windows to Linux, sound might only work through headphones jack, but not through speakers and subwoofer. The quick fix is to suspend your laptop and resume it back.
Bug
The internal speakers seems not to play any sound until volume is being increased significantly. This also occurs on Windows operation system as well as on Linux.
Sound pops twice during shutdown and sleep
Create new file:
/etc/systemd/system/beep-disable.service
[Unit] Description=Unloads audio module to prevent beep on shutdown DefaultDependencies=no [Service] Type=oneshot ExecStart=/bin/sh -c 'rmmod snd_hda_intel' [Install] WantedBy=shutdown.target suspend.target
and one more:
/etc/systemd/system/beep-disable-wakeup.service
[Unit] Description=Load sound module back on system resume After=suspend.target Wants=local-system-resume.service Before=local-system-resume.service [Service] Type=oneshot ExecStart=/bin/sh -c 'modprobe snd_hda_intel' [Install] WantedBy=suspend.target
Then enable beep-disable.service
and beep-disable-wakeup.service
as root.
Crackling sound
Add tsched=0
to pulseaudio config file as per instructions at PulseAudio/Troubleshooting#Glitches, skips or crackling.
Failed to initialize the NVIDIA GPU
If you receive error similar to this Failed to initialize the NVIDIA GPU at PCI:1:0:0 (GPU fallen off the bus / RmInitAdapter failed!)
, see here.
Messages during console login
After booting up, when Linux asks you to enter your login and password, some messages might appear similar to these:
Nouveau E[ PBUS][0000:01:00.0] MIMO write of 0x00000002 FAULT at 0x4188ac [ IBUS] Nouveau E[ DRM] Pointer to TMDS table invalid Nouveau E[ DRM] Pointer to flat panel table invalid
To resolve, refer to #Drivers.
USB devices and sleep
Hibernate via systemd works out of the box when the swap space or file is correctly identified in the resume kernel parameter. However, even though the system suspends properly it will lock up when resuming. This is due to the USB controller not properly turning off on its own. Create two the following files as shown:
/etc/systemd/system/root-suspend.service
[Unit] Description=Local system suspend actions Before=sleep.target [Service] Type=oneshot ExecStart=-/usr/bin/rmmod ehci_pci ; /usr/bin/rmmod ehci_hcd ; /usr/bin/rmmod xhci_pci ; /usr/bin/rmmod xhci_hcd [Install] WantedBy=sleep.target
/etc/systemd/system/root-resume.service
[Unit] Description=Local system resume actions After=suspend.target [Service] Type=oneshot ExecStart=/usr/bin/modprobe ehci_hcd ; /usr/bin/modprobe ehci_pci ; /usr/bin/modprobe xhci_hcd ; /usr/bin/modprobe xhci_pci [Install] WantedBy=suspend.target
Then enable root-suspend.service
and root-resume.service
as root.
Battery charging issues
This battery in this laptop can only be accessed by removing the bottom of the entire laptop, which requires removing 10 TORX-5 screws. That there appears to be a power issue related to the recharging USB port (the USB port with a lightning bolt) under Linux. When an externally powered device is plugged into the charging USB port and the system is power cycled, the battery indicator will begin flashing orange and the system no longer recognizes or charges the battery. One way to reset the charging circuit is to force shutdown by holding the power button for a few seconds. See this thread at the Ubuntu forums for other possible solutions.
Card reader does not detect cards
Due to unknown reasons, card reader does not detect cards. To resolve this, quickly pull out the card and insert it back for several times and after few seconds card will be detected in your system.
Tips and tricks
Touchpad switch
The touchpad can be toggled using a xinput
script.
Full fan speed
This is very helpful if you are about to play a heavy game. Install package lm_sensors, then follow Lm_sensors#Setup guide to set up sensors. Once you ready, just before every hard game run the following command:
# pwmconfig
If prompted, click y
and after a few seconds you are done. Fan spins at full speed.
Disable GPU throotling
If you have BIOS 208 installed and tried to play something heavy, you noticed that for a few seconds game runs for 60fps, but most of the time - 20-40fps. GPU performance is being reduced, so temperature can drop down and this is known as GPU throttling. This is strange behavior and even if temperature limit is set to 90c, GPU throttling occurs at 75c or even all the time.
To fix this, flash bios 206. If your BIOS version is newer than this, you must follow this guide, which requires you to have Windows installed to your laptop.
Special keys for window managers
If you prefer using a Window manager rather than a Desktop environment, most settings will not work out of the box, so you might need to manually bind every single FN
button combination. How to bind, see Extra keyboard keys in Xorg.
