New desktop environments (GNOME, KDE, and maybe even Xfce) support their own osd notifications for important events (volume up/down/mute and brightness up/down), which might be enough for most users. In order to use those notifications instead of the ones provided by TPB, map the keyboard-events of those keys to the proper keycodes.

Loading nvram at boot and give permission to access /dev/nvram

  • Check with lsmod if the nvram module is loaded on boot
  • If not, add nvram to MODULES=(... nvram) in /etc/rc.conf
  • Check /dev/nvram permissions, your user must have read access to it.
  • Edit /etc/udev/rules.d/51-arch.rules (WARNING: It will be overwritten with new udev update!)
KERNEL=="nvram",   NAME="misc/%k", SYMLINK+="%k", GROUP="kmem", MODE="0660"
  • Note: this line seems to work better for some users:
KERNEL=="nvram", GROUP="kmem", MODE="0660"
Note: Check if there is already a line matching nvram in the /etc/udev/rules.d/ directory. In this case, you have to modify the existing entry, and do not create a tpb.rules.
Note: Write access to nvram is only needed to set volume with MIXER ON. see /etc/tpbrc.

Setting a more readable color and better placement

/etc/tpbrc:

OSDCOLOR    Green
OSDVERTICAL 0
OSDHORIZONTAL 0
OSDPOS      MIDDLE
OSDALIGN    CENTER

Starting with KDE

~/.kde/Autostart/tpb-startup.sh:

# Start Thinkpad OSD daemon
if [ -x /usr/bin/tpb ] &&  [ -w /dev/nvram ] && [ -r /dev/nvram ]; then
    /usr/bin/tpb -d
fi

Starting with Fluxbox

~/.fluxbox/startup

# Start Thinkpad OSD daemon
if [ -x /usr/bin/tpb ] &&  [ -w /dev/nvram ] && [ -r /dev/nvram ]; then
    /usr/bin/tpb -d
fi

Play a sound on volume change

You can play a sound when using the volume buttons (mac like).

  • /etc/tpbrc
CALLBACK /usr/local/bin/callback_volume.sh
  • /usr/local/bin/callback_volume.sh
#!/bin/sh
[ "$1" = "volume" ] && exec canberra-gtk-play --file=/usr/share/sounds/freedesktop/stereo/audio-volume-change.oga
# chmod +x /usr/local/bin/callback_volume.sh
  • Then restart tpb.
