Samsung series 9

[anchorschmidt]

Thank you so much for this fix!!! Thank you!

900X4C with Kubuntu Precise, I can get over 9 hours on battery (until the 5-percent warning) with the 3.4 mainline kernel.

Hey, I have an older samsung series 9 (900X3A) but I think that the wifi is the same in both. I tried installing the 3.4 Kernel but my wireless driver would not work. Did you have to do anything special to get wireless to work?

On a different note, I know that the 15" series 9 supports 16gb even though it is only advertised as supporting 8gb. Has anyone tried 16gb in the 13"? I compile android from source so the more ram the better.

I got the N900 with all latest updates and everything that used to work still works fine. Nothing broke on update.

I seem to have an issue with the ambient light sensor causing my X to freeze when the state changes while the lid is closed.

What I have been able to do to get this to be reproducible with any accuracy is to close the lid. Shine a light, a BRIGHT light, into the laptop area aimed at the sensor as best as you can while opening the lid SLOWLY and pausing for a few seconds several times to ensure you trigger the sensor while the laptop is still 'closed'. When your screen returns it is frozen. You can move the mouse, the computer is still processing, but no more screen updates. Whatever was on your screen last is the same thing you see. Best way to test is have a video planing and repeat opening until it happens. I get about 1 per 5-7 will cause this to happen. The only option I have to recover my system is crash X with either a ctrl-alt-backspace or a hard reboot.

Any suggestions?

Fix for hdmi sound when connected to external monitor or tv.

from:
http://charlesmcruz.wordpress.com/20...-toggleswitch/

sorry for my english.

In a terminal:
sudo gedit /etc/udev/rules.d/hdmi.rules
Copy, paste, then save:
SUBSYSTEM=="drm", ACTION=="change", RUN+="/usr/local/bin/SToggle"
In the terminal:
sudo udevadm control --reload-rules
In the terminal:
sudo gedit /usr/local/bin/SToggle
Copy and paste the script below and then save it.
In the terminal:
sudo chmod 755 /usr/local/bin/SToggle
And that should do it! Hope it works!

in case the sound doesnt work in 5.1 mode, mine didnt
replace this line
sudo -u $USER pactl set-card-profile 0 output:hdmi-surround
with this
sudo -u $USER pactl set-card-profile 0 output:hdmi-stereo






#!/bin/bash
# Sound Toggle

# The following script toggles the between laptop speakers and hdmi audio (if detected).
# Version 1.0

USERID="$(cat /var/run/ConsoleKit/database | grep -B 6 is_active=true | grep uid= | cut -f 2 -d '=')"
USER="$(grep $USERID /etc/passwd | cut -f 1 -d ':')"
HDMI_STATUS="$(cat /sys/class/drm/card0-HDMI-A-1/status)"

if [ "${HDMI_STATUS}" = connected ]; then
sudo -u $USER pactl set-card-profile 0 output:hdmi-surround
else
sudo -u $USER pactl set-card-profile 0 output:analog-stereo+input:analog-stereo
fi

exit 0

I haven't read the entire thread, but hopefully this will help a few people.

I just received my series 9 900X4C and have installed xubuntu 12.04 and after following these steps, in decreasing order of necessity, have had no problems:


1. Add https://launchpad.net/~voria/+archive/ppa 'Linux on my Samsung' repo

2. Install 'samsung-tools' and 'samsung-laptop'
This will add Fn key functionality, like fan control, and fix the Fn brightness keys from causing flickering

3. Editing /usr/share/X11/xorg.conf.d/50-synaptics.conf
Add 'Option "AreaLeftEdge" "1000" to the section with the synaptics driver:

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
# This option is recommend on all Linux systems using evdev, but cannot be
# enabled by default. See the following link for details:
# http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html
      MatchDevicePath "/dev/input/event*"
        Option "AreaLeftEdge" "1000"
EndSection

This disables a section, 1000 'units' from the left side, of the touchpad so you don't accidentally use the touchpad when typing. Look up other options, the right side may be disabled as well (if you are left handed)

4. Remove the default XFCE4 dock and install cairo, which seems pretty lightweight for a dock though it has to be run in CPU mode.


I recommend the XFCE4 DE over Gnome3 for anyone who enjoying an active desktop and easily malleable panel bars. I'm getting more than five hours on battery, I haven't drained it completely yet.

EDIT: I just encountered this bug, where the battery adapter will be reported as being 'online' when unplugged:

I'm also experiencing the bug where the computer does not change battery states when plugging or unplugging the AC adapter. I haven't installed any of the samsung specific tools/kernel modules and am running kernel 3.5.0-10 from xorg-edgers. Also, I'm concerned the computer is not sleeping properly as when I close the lid and throw it in my bag to go to work it still seems to be churning out a great deal of heat.

It probably is not sleeping at all, given that lid events are not recognised. You should put it to sleep using the menu command.

Be careful with this, keeping it in a sleeve while it is not sleeping might kill it if it gets too hot

[senorgomez]

It's odd.
From my panel battery indicator:
Adapter is online
Battery is discharging

From `acpitool -a -b`:
Adapter is offline
Battery is discharging

And my 'sleep when lid is closed' rule doesn't get triggered.

A restart usually fixes this.

This is true for kernel 3.5? The Ubuntu Wiki article seems to indicate that the issue is fixed or is it the issue with the backlight being off when opening the lid that's fixed? Also, following the suggestions for enabling all function keys, I found that while keypresses on the wifi button and keyboard backlight keys were correctly recognized, pressing the keyboard backlight buttons caused the keyboard to stop functioning entirely.
