1、AMD64中,fcitx和eva、wine都已经不再适用,改用scim来输入,直接pkg_add -r zh-scim-tables,连五笔一起安装上了;eva和wine,都直接用virtualbox了。
2、安装zh_CN-kde
3、安装nvidia的驱动,需要/usr/src,可以到官方下载驱动,也可以到/usr/ports/x11/nvidia-driver/中安装,如果没有特殊的需要,可以不安装linux支持。
ATI驱动仍然不完善,用X700老莫名奇妙死机。
4、cvsup源,用cvsup6.tw.freebsd.org,速度100K+
5、用virtualbox来完成Flash和QQ。
6、在启用了显卡加速后,OPENGL的屏保程序,预览比测试和运行更耗CPU。
7、/一般分1G,但是默认的/root也在/中,所以要在virtualbox中,把所有存储方面的东西,从~root中修改,否则运行时会出disk_full的错误。
Virtualbox中,CPU的数量设置为跟宿主机相同,性能更好。在E5400下,设置一个CPU的情况下,虚拟机用XP,播放视频时CPU利用率在80%,设置了两个CPU,CPU利用率降到50以下。
8、wine目前不支持64位系统
9、wqy的几个新字体对液晶支持都不是很好,字发虚,点阵字还凑合。
FireFox用wqy点阵正黑,效果还不错。
10、声卡,由于有两个声卡,主板和显卡上都带,并且默认显卡上的优先,导致系统不出声音。
ls /dev时,显示有8个dsp
(1)/boot/loader.conf
snd_hda_load="yes"
(2)/etc/sysctl.conf
hw.snd.default_unit=4
声音方面的内核变量,主要用hw.snd和dev.pcm(网上很多资料写的是hw.pcm或dev.snd)
(3)5.1声道的设置
(4)声音的工具:mixer
11、多声道的处理
多声道播放,还是用smplayer,在音频上调整5.1声道。
(1)man sound
Multichannel Audio Multichannel audio, popularly referred to as ``surround sound'' is sup-
ported and enabled by default. The FreeBSD multichannel matrix processor
supports up to 18 interleaved channels, but the limit is currently set to
8 channels (as commonly used for 7.1 surround sound). The internal
matrix mapping can handle reduction, expansion or re-routing of channels.
This provides a base interface for related multichannel
ioctl() support.
Multichannel audio works both with and without VCHANs. Most bridge
device drivers are still missing multichannel matrixing support , but in
most cases this should be trivial to implement. Use the
dev.pcm.%d.[play|rec].vchanformat to adjust the number of chan-
nels used. The current multichannel interleaved structure and arrange-
ment was implemented by inspecting various popular UNIX applications.
There were no single standard, so much care has been taken to try to sat-
isfy each possible scenario, despite the fact that each application has
its own conflicting standard.
..................
dev.pcm.%d.[play|rec].vchanformat Format for VCHAN mixing. All playback paths will be converted to
this format before the mixing process begins. By default only 2
channels are enabled. Available options include:
s16le:1.0
Mono
s16le:2.0
Stereo, 2 channels (left, right).
s16le:2.1
3 channels (left, right, LFE).
s16le:3.0
3 channels (left, right, rear center).
s16le:4.0
Quadraphonic, 4 channels (front/rear left and right).
s16le:4.1
5 channels (4.0 + LFE).
s16le:5.0
5 channels (4.0 + center).
s16le:5.1
6 channels (4.0 + center + LFE).
s16le:6.0
6 channels (4.0 + front/rear center).
s16le:6.1
7 channels (6.0 + LFE).
s16le:7.1
8 channels (4.0 + center + LFE + left and right side).

用的是修改hints的方法
12、启动的时候Akonad报错,原因是mysql不能以root启动,如果是root用户,则要在/root/.local/share/akonadi/mysql.conf中的mysqld小节中添加:user=root。
13、启用桌面特效,半透明的效果和窗口的光环确实漂亮,但是要增加10%左右的CPU占用率,如果不启用显卡加速,特效启动不起来。
14、非root用户使用konsole的时候,如果locale没有设置(也可能会是没有设置为UTF-8),则会闪一下就消失,设置为locale为utf-8就可以使用。默认字体为9号,偏小,设置为12号要好一些。
15、如果K菜单下方的“收藏夹”、“应用程序”等为英文,检查一下locale设置,必须跟“系统设置”中的语言相对应才能正确显示。
16、RSS阅读器不支持中文?
17、环境变量设置的位置:
/etc/profile; /etc/xprofile; /etc/login.conf; 跟用户无关的
~/.cshrc; ~/.shrc; ~/.xinitrc ; ~/.profile; ~/.xprofile 跟用户有关的
在gdm配置文件夹中,有个Xsession,里面先是shell配置,如.cshrc等,再是/etc/xprofile,最后是~/.xprofile。
18、kwrite需要在“配置编辑器“->“打开/保存”中设置中文编码,否则不能保存中文,一般是utf-8比较保险。
