Arch Linux Hints and Tricks

ArchLinux-USB-Powersave.md

Mouse and Keyboard power off

Do you use an usb mouse and keyboard and have laptop_mode installed under your Arch linux ? Then maybe you have the same problems as me - mouse and keyboard getting inactive every 2 seconds or so.

To solve this, go to /etc/laptop-mode/conf.d and copy usb-autosuspend.conf to /etc/laptop-mode/conf.d/board-specific. After that run lsusb and get the ID of the usb device you want, e.g., 093a:2500 .

Open the board-specific/usb-autosuspend.conf file and find the AUTOSUSPEND_USBID_BLACKLIST conf option. Put the desired usb IDs there. You might need to run sudo laptop_mode afterwards to reload the configs.

There you go. No more suspending of your usb devices attached ;).

Joystick moves mouse.md

Joystick/Gamepad configuration

I had the same problems as you, and found 2 solutions

1. remove xf86-input-joystick. All of my applications that required joysticks could detect them, unfortunately they lacked deadzone settings so joystick control was not as good as i wanted.

2. the correct place for the startkeysenabled / startmouseenabled settings appears to be 50-joystick.conf, which comes with the xf86-input-joystick package.

this is my edited version of 50-joystick.conf :

  Section "InputClass"
      Identifier "joystick catchall"
      MatchIsJoystick "on"
      MatchDevicePath "/dev/input/event*"
      Driver "joystick"
      Option "StartKeysEnabled" "False"
      Option "StartMouseEnabled" "False"
  EndSection

No Standby Monitor.md

Disable standby

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 0 0
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
### add these
        Option "BlankTime" "0"
        Option "StandbyTime" "0"
        Option "SuspendTime" "0"
        Option "OffTime" "0"
EndSection

Thinkpad Audio Keys.md

Thinkpad Audio Keys

When using Archlinux with Xfce4 on a Thinkpad you may configure the audio keys using either of the two methods below:

Using Xfce4 Application Shortcuts

• Go to Settings / Keyboard / Application Shortcuts
• Click on Add
• Enter the mute toggle command
  • No pulseaudio - amixer set Master toggle
  • With pulseaudio - amixer -D pulse set Master toggle

Using xbindkeys

On the command line:

Use the following to see what type of binding currently exist:

xbindkeys -s

Create a file .xbindkeysrc.scm in your home directory and add the following lines:

Toggle audio on/off:

(xbindkey '("XF86AudioMute") "amixer set Master toggle")

Note that you need to enter -D pulse, if you have pulseaudio installed.

Volume up

(xbindkey '("XF86AudioRaiseVolume") "amixer set Master 2dB+ unmute")

Volume down

(xbindkey '("XF86AudioLowerVolume") "amixer set Master 2dB- unmute")
