daily commands on debian

“CDRom is not detected in Debian installer”

量产使用USB-DVD/CD安装debian的时候

“Unable to resolve UUIDs”

对于经常折腾系统的同学，“Unable to resolve UUIDs”频繁出现, 需要删掉废弃的UUID ＃ nano /etc/fstab

debian wheezy driver

在一些配有旧款ATI显卡和Marvell Yukon网卡的笔记本装debian wheezy，总会为装驱动而头疼。我这里有一款10年产的hp 4411s 481，5月份折腾过。弄了个64位版的,

首先看看显卡驱动,很多依赖文件都得装上＃ sudo apt-get fglrx-driver fglrx-control fglrx-glx-ia32 fglrx-atieventsd fglrx-modules-dkms 还有Kernel Header package和官方驱动AMD 催化剂13.1 Linux x86 专利显示驱动 , 注意也许要手动添加headers的链接，比如这个：/lib/modules/3.2.0-4-amd64/build/include/linux/version.h;最后也许那些驱动装不了,还是看看内核编译的信息＃ cat /proc/version 准备定制驱动和配置自己编译内核吧，呵呵。

对于网卡驱动，kernel 2.6.x Linux Driver Install Package for Yukon Devices, 同样是问题多多。sk98lin driver也太古老了。
