我最近在计算机上安装了lubuntu 11.04 powerpc的新副本。我正在按照此Fourm帖子中的说明进行操作：http ://ubuntuforums.org/showthread.php?t=1798792 我所得到的只是命令行提示符。我尝试通过无济于事地运行“ startx”来启动X。
我用谷歌搜索了大约2个小时，但没有成功。
我有一个Mac G4 800mhz 832mb ram 5400rpm 10gb和37gb希捷内部硬盘。
今天更新2:52 PM
这是xorg.0.log：

我从未看到过grub，如何将其添加到grub引导字符串中？

...哦，是的-powerpc ...根据wiki wiki.ubuntu.com/PowerPCFAQ-它不会拖拽其yaboot.conf文件-朝Wiki页面底部看。或者（或可能更好？）在您的xorg.conf中指定“ vesa”而不是“ ati”

alexy13-您的xorg.conf文件看起来非常复杂-您可以简化它吗？-论坛链接建议“ 1个设备部分，1个屏幕部分，1个监视器部分”

xforcevesa到您的grub引导字符串中-这应该会为您提供可用的图形桌面。
