大约每 7 分钟就有一次游戏卡顿
Kas*_*par 6 xorg graphics games 12.10 logs
每当我在 Linux 机器上玩游戏时，它每 7 分钟左右就会断断续续大约 5 秒。看起来不是一个严重的问题，但它仍然有点烦人。因此，关于如何甚至追踪该错误的原因的任何想法，然后也可能尝试修复它。
我在 Acer aspire 5552g 上安装了 Ubuntu 12.10，它具有：
- AMD 2.20 GHz 处理器
- 带有最新 AMD 专有驱动程序的 Radeon HD 5650。
- 4 GB 内存
- DE：侏儒 3
更新：
我查看了发生卡顿时的 CPU 使用率图表，它显示一个内核（双核）在发生这种情况时上升到 100%，而另一个保持原样。这可能是 CPU 故障的迹象，还是只是操作系统安装不当？
看来实际上是Xorg的问题。当出现卡顿时，Xorg 似乎占用了我大约 60% 的 CPU 容量。
关于如何从这里进行故障排除的任何想法？
现在检查日志文件，这是我拥有的日志列表：

看到这个日志似乎又一次不想显示错误了。
编辑：将一些屏幕截图与发生口吃时的顶级监控联系起来。也许它有点帮助。
可以看出，当出现卡顿时，Xorg 会从一个内核中占用大量处理能力。这次只有 12.6%，但更严重的占 37%，这会导致真正的锁定几秒钟。另外我想知道这是否是 Xorg 造成的错误，我不应该查看 Xorg 日志吗？但是我应该监控哪一个，因为它们太多了。此外，当我尝试监视 Xorg.3.log 时，它没有显示任何错误的时间戳，因此我猜可能很难从那里读取内容。

如果您尚未安装 AMD 显卡驱动程序，可以在此处下载
如果这不起作用，请尝试使用以下命令卸载并重新安装 xorg
sudo apt-get remove --purge xserver-xorg
然后
sudo apt-get install xserver-xorg
