conky 导致 xorg 高 CPU 使用率 - ati/radeon 加速问题

我正在运行 debian jessie，最近从 fglrx 视频驱动程序切换到免费的 ati radeon 驱动程序。我设法设置了它，但我注意到 xorg 导致高 CPU 负载：30-50%。
谷歌搜索了一下，查看了 htop 并关闭了进程，我发现 conky 导致 xorg 高 CPU 使用率。默认设置/etc/conky.conf没问题，CPU 负载保持在 2% 以下。
我的自定义~/.conkyrc运行良好，并没有导致 fglrx 15.9 驱动程序的高 CPU 负载。所以我推测免费的 radeon 驱动程序不喜欢某些设置。
我附上了我的~/.conkyrc。也许有人可以看看它并告诉我我遗漏了什么？

内核：Linux 3.16.0-4-amd64 x86_64 Debian
X 服务器：X.Org X Server 1.16.4
Radeon 模块版本：7.5.0
Conky 版本：1.9.0-6

好吧，你的评论不是真正的答案，但给了我一个提示。我深入研究了man radeon一下https://wiki.archlinux.org/index.php/ATI（debian wiki 相当神秘或过时：仍然建议使用 EXA 进行性能调整），查看Xorg.0.log并找到了原因：
Xorg 自动检测为 TAHITI 之前的 GPU（我的是 ARUBA）加载 EXA 加速方法。而且 - 确实 - EXA 很慢。

因此，解决方案是自定义/etc/X11/xorg.conf.d/20-radeon.conf加载glamor加速方法：

Section "Device"  
    Identifier  "Radeon"  
    Driver "radeon"  
    Option "AccelMethod" "glamor"  
    Option "DRI" "3"  
    Option "TearFree" "on"  
EndSection

注意：我发现一些文章指出 DRI3 需要 Xorg 版本 1.17 或更高版本以及 ati/radeon 驱动程序 7.6 或更高版本，因此如果它不起作用，请不要感到惊讶。
现在 Xorg 使用的 CPU 不超过 2%。问题解决了。
