怎么改??????????????????
原因如下(粗字)
在X窗口下，按ctrl+alt+back sapce不能重起x，系统关机。我的系统是mandrake9.1
主板为sis芯片
但是，在其他linux下，就可以，
另外,我发现,开机,在运行到 NTloader 选单时
(我装的是多系统,win98 win2000 mandrake9.1 debian,使用windows2000的引导程序引导多系统)
按ctrl+alt+back sapce，系统关机
网上说是sis芯片的事.
可是,为什么进入win98 /win2000/debian 按ctrl+alt+back sapce都没事???
单单进入mandrake9.1 不行???
经过多次实验，原来原因是bios把ctrl+alt+back sapce认作关机键了，在cmos里将按下关机键设置为休眠，那么，按ctrl+alt+back sapce，系统就休眠。
我的是微星645Ultra主板,bios已升级到最新,sis645/sis961芯片
我这knoippix就可以使用ctrl+alt+back sapce,因此,通过软件也可以解决这个硬件问题
问题的关键是bios把ctrl+alt+back sapce健看作是主机箱上的关机按钮,所以,操作系统内只要屏蔽bios的关机中断即可.
看这位外国老兄同样的问题:

Hi,
I can't remember the brand and the model of the motherboard, but it is
based on a SIS chipset. (the machine is at 1000km over). The machine
isn't a Fujitsu, it's a "no name" machine.
I didn't remember any X lookup, I was running a mdk8.1, the machine is
quite stable.
