我最近在计算机上安装了最新的 lubuntu 11.04 powerpc。我按照此论坛帖子中的说明进行操作：http://ubuntuforums.org/showthread.php?t=1798792 我得到的只是命令行提示符。我尝试通过运行“startx”来启动 X，但没有成功。
我在 Google 上搜索了大约 2 个小时，但没有成功。
我有一台 Mac G4 800mhz 832mb ram 5400rpm 10gb 和 37gb seagate 内置硬盘。

我的显示器是索尼 Trinitron Multiscan 20se II。我已经尝试安装 Linux 两周了，但我还没有放弃！虽然差点就放弃了
答案1
我放弃了。经过三周的故障排除，这太难了。我决定在 iMac 上的虚拟盒上安装 Ubuntu。然后我删除了它，因为它与 Unity 有问题，经过两天的尝试修复后，我再次放弃了。感谢大家对我的帮助，因为它确实有帮助。
嗨，麦克。好久不见了。
答案2
第二次尝试
阿夫托勒有已报告通过在 xorg 文件中添加以下几行来使带有 ATI Rage 128 设备（看起来像您的）的 iMac 正常工作：
“监控”部分 水平同步 28-51 绿清新 43-60 “屏幕”部分 “显示”子部分 模式“1024x768” 结束子节 “DRI”部分 型号 0666 结束部分
您也可以将其更改Modes "1024x768"为您的（1152x870）。请小心谨慎，因为据报告设置大于您的卡支持的分辨率会损坏显示器。
第一次尝试
您知道您的显示器的规格吗？
看一下这：
“
消息：“找到屏幕，但没有可用的配置”
您收到一条错误消息：
(EE) 找到屏幕，但是没有可用的配置。 严重服务器错误： 未找到任何屏幕
在大多数情况下，这意味着您的配置没有可用的视频模式。指定或默认视频模式列表中的每个条目都会被检查是否在限制或硬件范围内：它是否在为显示器指定或探测的同步范围内，它是否可以与视频卡上可用的内存配合使用，或者像素时钟是否在芯片组支持的范围内。还有更多的限制。对于每个被拒绝的模式，您可以在日志文件中看到被拒绝的原因：
... （II）VGA（0）：不使用默认模式“320x200”（vrefresh超出范围） （II）VGA（0）：不使用默认模式“720x400”（模式内存不足） （II）VGA（0）：不使用默认模式“360x200”（水平同步超出范围） ...
在大多数情况下，显示器范围是您的模式被拒绝的原因。请尝试小心地扩展这些范围，直到您获得一个工作模式。请注意：在较旧的显示器上，您需要小心扩展范围，因为它很容易被破坏。您收到此消息的原因可能还有其他。
如果您的硬件不支持指定的深度。
在这种情况下，请尝试深度 8，或者如果您使用的是 vga 驱动程序，甚至可以尝试深度 4。如果您指定了驱动程序无法处理的选项组合。
如果加载所需的子模块不成功。在这种情况下，您将收到加载失败的消息。请尝试调查原因。该消息可能会给您一个线索：您可能使用了错误版本的模块，或者文件可能不存在。
“
答案3
您最新编辑中的错误是由于缺少监视部分造成的：
我可以根据您给出的值建议以下简单的 xorg.conf：
Section "Device"
Identifier "Configured Video Device"
Driver "ATI Technologies Inc Rage 128 PF/PRO AGP 4x TMDS"
EndSection
Section "Monitor"
Identifier "Configured Monitor"
Horizsync 24-82
Vertrefresh 56-85
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
Subsection "Display"
Modes "800x600" "1024x768"
EndSubsection
EndSection
Section "DRI"
Mode 0666
EndSection
如果你没有正确的驱动程序“ATI Technologies Inc Rage 128 PF/PRO AGP 4x TMDS”值，请尝试使用“vesa”
