大概上周开始,用着用着会突然黑屏,屏幕像关掉了一样。什么反应都没有。
按Ctrl+Alt+f1~f6都没反应,屏幕就是黑掉。
显卡:Ati 7500
起初怀疑显卡和xorg.conf的配置问题。重新提交配置,网上也找了同型号的配置。但还是一样的情况。
后来想想可能是无线网卡的问题。
无线是:Athores 2414 Ubuntu8.04起初刚安装好系统的时候,认的出来,也可以用,但是使用开源驱动。在硬件驱动里都有显示。
后来发现信号不好,换了windows下的驱动。
过了几天发现黑屏问题。
网卡现在把windows下的驱动删除掉的话,就认不出来。

怎么回事啊?
怎么会突然黑屏幕的。

在黑屏后,使用过 Ctrl+Alt+F1 然后登陆,su 后 poweroff 或者 reboot 都没反应。
硬盘灯也不闪。

难道是屏线的问题,但是在WIN下是没问题的,随便摆动屏幕都没关系。
想不通是什么原因。
晚上再把无线驱动装一下 。
