Broadcom BCM43142 on Ubuntu 13.04 64bit

download the file: http://jas.gemnetworks.com/debian/po...19-1_amd64.deb
sudo apt-get install linux-headers-generic build-essential dkms
then install the debian package
but you need to install the following stuffs for 13.04
- linux-headers-generic
- bcmwl-kernel-source
then you can use wifi!
ps: This document is just integrate some contents from the other sites.

My ubuntu (11.10 Oneiric) on ASUS U41S

I bought a laptop,ASUS U41S, and installed ubuntu 11.10 on it. But found out many issues and record how to fix it listed below. The solution are from my experiences, many links (googling) and references, just integrate all fixes here. Not sure can fit all people using ubuntu on asus.

1. Fan Speed control.
When I power on my laptop with Ubuntu, the fan speed always (or usually) make lots of noises. Then I find a way to make it being quieter, that's lm_sensors. (but maybe still need to refer to power consumption as item 2.)

- Install lm-sensors


2. power consumption (2.5 hrs to 6 hrs)

- Enable ACPI ASPM
edit /etc/default/grub and add pcie_aspm=force
update-grub

#The major eating-power-monster will be the nvidia and unity3D with compiz, so change to 2D first.
- About acpi_call
git clone http://github.com/mkottman/acpi_call.git
cd acpi_call
make
sudo insmod acpi_call.ko # first trying
--> then copy acpi_call.ko to /lib/module/... and depmod -a
./test_off.sh # you can use this script to find out your "parameter" of acpi_call to disable the nvidia h/w

*** build acpi_call in dkms format under 12.10 ***
apt-get install dkms
put acpi_call folder into /usr/src/acpi_call-0.1
modify Makefile and dkms.conf

Makefile
obj-m := acpi_call.o default: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules clean: rm acpi_call.mod.o acpi_call.o acpi_call.ko
dkms.conf

PACKAGE_NAME="acpi_call"
PACKAGE_VERSION="0.1"
CLEAN="make clean"
BUILT_MODULE_NAME[0]="acpi_call"
DEST_MODULE_NAME[0]="acpi_call"
MAKE[0]="make IGNORE_CC_MISMATCH=1 KDIR=$kernel_source_dir PWD=$dkms_tree/acpi_call/0.1/build"
DEST_MODULE_LOCATION[0]="/kernel/drivers/acpi"
AUTOINSTALL="yes"

build dkms format

sudo dkms add -m acpi_call -v 0.1
sudo dkms build -m acpi_call -v 0.1
sudo dkms install -m acpi_call -v 0.1

(can check the status with "dkms status" command)
and here is the link for reference.

http://hybrid-graphics-linux.tuxfamily.org/index.php?title=Acpi_call

---- save these in /etc/rc.local -----
# remove nouveau for nvidia before X
modprobe -r nouveau
# Disable nvidia h/w
modprobe acpi_call
echo "\_SB.PCI0.PEG0.GFX0.DOFF" > /proc/acpi/call
#then reboot, you should have more than 5 hrs power consumption now.

3. Suspend issue (can't fix hibernate yet)
From the solution, looks like the issue caused by usb.
- add the contents below into /etc/pm/sleep.d/20_suspend and chmod to 755

好玩的，一行列出99乘法表

echo $[{1..9}*{1..9}] | xargs -n9 | column -t

Why you cannot make your command or parameter complete by pushing TAB under Ubuntu

Just find out the package name for this function, and keep this info here in case forget this name.
*bash-completion

Who enable this function? The answer is bash script.

1. ~/.bashrc
2. /etc/profile

You can also check which package support this or program it by yourself.
/etc/bash_completion.d

How to change the "indicator" default setting, like mail agent

There is no setting option in gconf-editor or panel properties.
But you can just use the file to change the preferred application.

- In /usr/share/indicators/messages/applications/ there are some files, like empathy/evolution/gwibber in my folder by default.
- You can add a "thunderbird" file.
- And add a line in it as "/usr/share/applications/thunderbird.desktop".
- Then~~~you will see the indicator show you "Mozilla Thunderbird" dynamically.

Enable/Calibrate touch screen on EeeTop ET1602 for Ubuntu 10.04 (Lucid)

Have a chance to port Lucid on the EeeTop machine. There are some problems in touchscreen and resolution, and here is how to fix it.

1. touchscreen
In Lucid, evdev is the default driver for X input devices, but it's not useful for this type machine. So you need to install the "evtouch" driver, the package name is "xserver-xorg-input-evtouch".

aptitude install xserver-xorg-input-evtouch

Then you need to modify the default xorg.conf (create a new one under /etc/X11/), and below is the details.

--------------------------

Monitor "Configured Monitor"
Device "Configured Video Device"

EndSubsection
EndSection

--------------------------

And also need to add "69-touchscreen.rules" udev rule under /etc/udev/rules.d
notes: check sysfs by the command
udevadm info -ap /sys/class/input/event8

--------------------------
KERNEL=="event*", SUBSYSTEM=="input", ATTRS{idVendor}=="1bfd", ATTRS{idProduct}=="1688", SYMLINK+="input/evtouch"
--------------------------

BTW, explain how I have the right "ModeLine" parameters here.
We can use the "PowerStrip" tool (Windows tool) to have the values.
Below is the link to teach you how to get the right values by PowerStrip.
