刚刚安装了 Ubuntu 11.04，我的笔记本电脑屏幕停止工作了，尽管外接显示器仍能正常工作。它甚至无法显示 BIOS。
它在 debian 升级期间（昨天）停止工作，所以我安装了 ubuntu，希望它能修复它。
这是一台装有 ATI 芯片的华硕电脑，我唯一尝试过的就是安装 fglrx 驱动程序，但是它们导致了内核崩溃，而且我至今无法让它在没有静音或启动的情况下启动。

并且显然 xorg.conf 不再存在。
我很抱歉没有早点发布此信息，我从来没有遇到过这样的主显示器问题，所以我不确定什么会有所帮助。
答案1
这听起来像是硬件问题。主板和显卡应该没问题，因为外接显示器可以正常工作。这不可能是驱动程序问题，因为甚至没有显示 BIOS。要么是屏幕坏了，要么是电缆问题。祝你好运。
