pve安装时候出现找不到 ast_dri.so,无法启动 x server 解决方案.

报错大概如下;

解决方案:
debug模式,或者正常模式下. x server启动失败后会回到中断窗口.

1. 配置xorg.conf

Xorg -configure
mv xorg.conf.new /etc/X11/xorg.conf
nano /etc/X11/xorg.conf

2. 修改/etc/X11/xorg.conf

• 2.1 找到 Load "glx" 替换为 Disable "glx",然后再下一行加入 Disable "glamoregl"
• 2.2 找到 Driver "modesetting" 替换为 Driver "fbdev"

然后执行 startx,稍等一会儿就会出现安装界面. 之后按正常流程安装即可.

如果安装好之后自动退出x server,手动重启即可. exit/reboot
