HP Touchsmart TM2 rotate display using rotate button

Save this in a file (ex. key-rotate-display.sh) give it execute permissions and add to startup applications

#!/bin/bash

KEY_ID="161"
 
primaryScreen=`xrandr | grep primary | cut -d' ' -f1`

stylusDev=`xinput --list | grep "Wacom .* stylus" | grep -o "id=[0-9]*\W" | grep -o "[0-9]*"`

Wacom Calibration Script (for Touchsmart TM2, X220t, X200t)

Because gnome tool does not work

#!/bin/bash
X_IFS=${IFS}
IFS='%'
DEVICES=( `xsetwacom --list devices | tr "\t" "%" | cut -d% -f1 |  tr "\n" ","` )
IFS=','
DEVICES=( $DEVICES )
value=$(zenity --list --title "Window title" --text "Select the input device you want to calibrate" --column "Detected input devices" "${DEVICES[@]}" )
value=$(echo $value | sed 's/ *$//g')
IFS=${X_IFS}
xinput_calibrator --device "$value" > /tmp/__xinput_cal.data
MinX=$(cat /tmp/__xinput_cal.data | grep Option | grep MinX | awk '{print $3}' | tr \" " ")
MaxX=$(cat /tmp/__xinput_cal.data | grep Option | grep MaxX | awk '{print $3}' | tr \" " ")
MinY=$(cat /tmp/__xinput_cal.data | grep Option | grep MinY | awk '{print $3}' | tr \" " ")
MaxY=$(cat /tmp/__xinput_cal.data | grep Option | grep MaxY | awk '{print $3}' | tr \" " ")
rm /tmp/__xinput_cal.data

Fix NVIDIA Optimus / Intel libGL conflict on SL 6.1

#!/bin/bash
cd /usr/lib
rm libGL.so.1
ln -s libGL.so.1.2 libGL.so.1

Fix "Location is not folder" / exo-utils problem / use nautilus in xfce

Create a open.sh file somewhere with:

#!/bin/sh
if [ $# = 0 ]; then
        nautilus "$PWD"
elif [ -d "$1" ]; then
        nautilus "$1"
else
        xdg-open "$1"
fi

make it executable, then run

exo-preferred-applications

and set your script as the default file manager. Now for files the default viewer will be opened (for example, evince for pdf) and nautilus for folders.

Fix crackling sound on USB audio with nvidia card

If the USB controller shares interrupts with the NVIDIA card, Powermizer could cause crackling sound when an USB sound card or headphone is connected.

To solve, I forced the Powermizer settings at the lowest performance by adding

Option  "Coolbits" "1"
Option  "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3"

To the “Device” section in xorg.conf Other info at http://linux.aldeby.org/nvidia-powermizer-powersaving.html
