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:
Device Drivers ---> Generic Driver Options ---> External firmware blobs to build into the kernel binaryI 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
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")
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
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
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
