====== Issues when install Gentoo on Acer 4820G ======

I don't have so much money to buy a Mac of Thinkpad.So I buy a powerful but cheaper laptop Acer 4820G.Sometimes I have a thought of anti-Mac,I don't have so much money to burning.

I think the suitable is the best,so I choose it.

Of course,I need to install Gentoo on it.Previously,I think I will have a lot of issues to resolve, as your wish I have it indeed.But all the procedure seems ok,don't have very serious issue.The mostly I think is the wireless driver.

So I make a note of the issues I have meet here,when I need to install Gentoo again,it will be a greatly helper.

My kernel config:http://paste.pocoo.org/show/384046/

===== The wireless driver =====
Refer to http://www.lxg.de/2011/04

localhost ~ # lspci -v|grep -i net
02:00.0 Ethernet controller: Attansic Technology Corp. Device 1073 (rev c0)
03:00.0 Network controller: Broadcom Corporation Device 4357 (rev 01)

Step1:
  mkdir ~/kernelgit
  cd ~/kernelgit
  git clone git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git

Step2:
<code>
Device Drivers  --->
	Generic Driver Options  --->
		External firmware blobs to build into the kernel binary
</code>
I fill it with bcm43xx-0.fw,

Step3:

Also I need to copy 
  cp brcm/bcm43xx* /lib/firmware/brcm/
  cp brcm/bcm43xx* /usr/src/linux/firmware/

Then compile the kernel as usual:
  make
  make modules_install
  cp /arch/x86/boot/bzImage /boot/kernel-2.6.38-r2
  
Then reboot,I can start net.wlan0

==== How to enable net.wlan0 tips ====

1.Config /etc/conf.d/net
<code>
localhost linux # cat /etc/conf.d/net|grep -v ^#|grep -v ^$
config_eth0=("dhcp")
modules=("wpa_supplicant")
wpa_supplicant_wlan0="-Dwext"
config_wlan0=("192.168.1.20/24")
routes_wlan0=("default via 192.168.1.1")
</code>

2.Make a soft link of net.lo
  ln -s /etc/init.d/net.lo /etc/init.d/net.wlan0
3.Use rc-update add net.wlan0
  rc-update add net.wlan0 default
==== Use ndiswrapper ====
I also use indiswrapper to install the driver which is used for Windows.Of course it works ok:

Install
  ndiswrapper -i oem1.inf
  
Uninstall (ls /etc/ndiswrapper)
  ndiswrapper -i oem1

===== Chinese input method Fcitx =====
I always use fcitx as my input method.First I have the tips by fcitx,but I can't invoke it,though it has the config icon on the panel.

I remember it is related with the locale,because I use the en_US.UTF-8 as the locale.

So need to modify the locale:
  vim /etc/profile.env
Change LC_CTYPE
  export LC_CTYPE='zh_CN.UTF-8'

Then edit the locale.gen
  vim /etc/locale.gen
Add these:
  en_US ISO-8859-1
  en_US.UTF-8 UTF-8
  zh_CN.UTF-8 UTF-8
  zh_CN.GBK GBK
  zh_CN GB2312
  zh_CN.GB18030 GB18030


The update env
   env-update
   locale-gen
Also need add these to .bashrc
  export XMODIFIERS="@im=fcitx"
  export GTK_IM_MODULE=xim
  export XIM=fcitx
  export XIM_PROGRAM=fcitx

My locale
<code>
localhost linux # locale
LANG=en_US.UTF-8
LC_CTYPE=zh_CN.UTF-8
LC_NUMERIC=en_US.UTF-8
LC_TIME=en_US.UTF-8
LC_COLLATE=en_US.UTF-8
LC_MONETARY=en_US.UTF-8
LC_MESSAGES=en_US.UTF-8
LC_PAPER=en_US.UTF-8
LC_NAME=en_US.UTF-8
LC_ADDRESS=en_US.UTF-8
LC_TELEPHONE=en_US.UTF-8
LC_MEASUREMENT=en_US.UTF-8
LC_IDENTIFICATION=en_US.UTF-8
LC_ALL=
localhost linux # locale -a
C
en_US
en_US.iso88591
en_US.utf8
POSIX
zh_CN
zh_CN.gb18030
zh_CN.gb2312
zh_CN.gbk
zh_CN.utf8

</code>  

Edit /etc/gtk-2.0/gtk.immodules,add en
  "xim" "X Input Method" "gtk20" "/usr/share/locale" "en:ko:ja:th:zh"
/etc/gtk-2.0/i686-pc-linux-gnu/gtk.immodules,add en
  "xim" "X Input Method" "gtk20" "/usr/share/locale" "en:ko:ja:th:zh"



===== rc-update del net.eth0 is useless =====
Though I have deled net.eth0 from default,but I still will see the net.eth0 starting and timeout without wirledlines

Edit /etc/conf.d/rc
  vim /etc/conf.d/rc
Change RC_PLUG_SERVICES like this:
  RC_PLUG_SERVICES="net.wlan0 !net.*"
  
  





===== Sound alsamixer =====
First it doesn't have sound,though I have used Fn+Volumn up to adjust the sound level,but it useless.

So need to use alsamixer to adjust it
  alsamixer
But after reboot laptop,it still no sound,it seems it can't store/restore the pre-settings.

So add this to /etc/conf.d/local.start
  alsactl restore

add this to /etc/conf.d/local.stop
  alsactl store
