（已解决）升级系统后无法启动X

Hosanna

出现这个问题应该是在一次emerge -avuDN world之后的，在网上搜了两天还找不到解决方法，只能请教大家了：

显卡明明是PCIE接口的呀，怎么会是ISA了呢？

备份你的xorg.conf，然后用nvidia-xconfig重新生成一个

Hosanna

试过，问题依旧！

acevery

因为udev没有启动，导致/sys是空的。
具体可以这么解决:

1. cd /etc/runlevels/sysinit
2. ln -s /etc/init.d/udev

复制代码

这样你下次重启的时候就会启动udev，/sys挂载后，X就可以找到你的显卡了。
重启前手动启动udev就可以先解决当前的问题:

1. /etc/init.d/udev start

复制代码

接下来启动X即可。

EE --> ERROR

2. cat /etc/X11/xorg.conf | grep freetype

复制代码

comment it!

2. sed -i -e 's/\s\{1,\}Load\s{1,\}"freetype"/#    Load "freetype"/' /etc/X11/xorg.conf

复制代码

freetype影响不大啊  ，我的一直都是(EE) Failed to load module "freetype" (module does not exist, 0) ，但是X可以正常进入 ， 后来我嫌这个烦  就注释掉了.

都没仔细看帖吧。。这个才是原因吧

没找到显卡。没遇到过这种问题

是不是显卡驱动的问题？
