I'm uploading right now a new kernel with a patch applied which should fix your problem.
It will be available in the next few hours, the time to build it.
Let me know if it works.
[NC10] Kernel 2.6.31
Re: [NC10] Kernel 2.6.31
Hi voRia, your application of the fix was good. I am now able to use my 3g USB modem again. [To make this post.]
Sorry it took such a long time to test it. I tried to do a dual-boot with Karmic and the 9.10 installer partitioner crashed and hosed my Jaunty ext3 filesystem. It took about 18 hours for fsck to fix all the errors!
Back up and running. Thanks.

Re: RE: [NC10] Kernel 2.6.31
Hey all, brand new to the forum but came here looking for a way to fix the brightness issues on my Samsung N150 Plus.
The bash script posted by voRia wasn't working for me 'out of the box' so to speak. I have modified it slightly, my first time messing with bash scripts.
Usage is for me:
I've added a line to the script to echo the current set value if you don't give parameters.
And:
set value must be decimal from 0-255
inc value must be decimal from 0-255 (increase)
dec value must be decimal from 0-255 (decrease)
Be careful setting the value to 0 or decreasing the value to 0, as it turns off the display backlight completely.
I know I've kicked up something pretty old on this forum but I needed a fix, maybe other do to
Let me know if there are any issues/questions
and thanks to voRia for most of the hard work

The bash script posted by voRia wasn't working for me 'out of the box' so to speak. I have modified it slightly, my first time messing with bash scripts.
Code: Select all
#!/bin/sh
# adjust backlight via setpci and dpms via vbetool
# Check if root called this script
USER=`whoami`
if [ $USER != "root" ]; then
echo "Need to be root to run this script."
exit 1
fi
# Get old value
OLD2=`setpci -s 00:02.0 F4.B`
OLD=0x$OLD2
case "$1" in
inc)
# Check if value given for increase
if [ -z "$2" ]; then
echo "Usage: $0 $1 <value>"
exit 1
fi
# Take second argument as value to increment
NEW=$(( $OLD + $2 ))
# Set new value
$0 set $NEW
;;
dec)
# Check if value given for decrease
if [ -z "$2" ]; then
echo "Usage: $0 $1 <value>"
exit 1
fi
# Take second argument as value to decrement
NEW=$(( $OLD - $2 ))
# Set new value
$0 set $NEW
;;
set)
# Check if value given
if [ -z "$2" ]; then
echo "Usage: $0 $1 <value>"
exit 1
fi
# Take second argument as value to set
NEW=$2
# Check if value less than 0
if [ "$NEW" -lt "0" ]; then
NEW=0
fi
# Check if value greater than 255
if [ "$NEW" -gt "255" ]; then
NEW=255
fi
# Set new value
setpci -s 00:02.0 F4.B=`echo "obase=16; ibase=10; $NEW" | bc`
;;
toggle)
# Path to logfile
LOG=/tmp/backlight.log
# Check if logfile does not exist
if [ ! -f $LOG ]; then
vbetool dpms off
touch $LOG
else
vbetool dpms on
rm -rf $LOG
fi
;;
*)
echo "Usage: $0 (inc <value>|dec <value>|set <value>|toggle)"
echo "Current Value: $OLD2"
exit 1
;;
esac
exit 0
Usage is for me:
Code: Select all
gksudo ./myscript.sh
And:
Code: Select all
gksudo ./myscript.sh set XX
gksudo ./myscript.sh inc XX
gksudo ./myscript.sh dec XX
inc value must be decimal from 0-255 (increase)
dec value must be decimal from 0-255 (decrease)
Be careful setting the value to 0 or decreasing the value to 0, as it turns off the display backlight completely.
