最近刚从 13.1 升级到 13.2, 顺便把原来的全黑主题换成了透明的 diamond 主题，效果不错。可是第二次开机的时候窗口边框之类应该透明的地方都显示成了黑色，konsole 的透明背景也不能用了，在配置 - 外观栏里显示“当前桌面不支持透明效果”（大意）。
后来发现必须到 系统设置 -> 桌面效果 里面改一个混成类型再应用，才能正常显示透明效果（openGL 2.0 或者 openGL 1.2 都可以，除了 openGL 3.1 会导致 kwin 崩溃）。但每次开机都得重新设一次。
看过 /var/log/Xorg.0.log，没有 Error，不知道问题出在哪里，是不是还有别的 log 需要查看？感觉应该是 KDE 内部的小问题，但是不会排查……
什么显卡，什么驱动？
机子是 i3-370 的 intel 集显和 NVIDIA GT 335M，N 卡已经用 bbswitch 禁用掉了，所以只有 Intel 显卡，Xorg.0.log 里也只检测到 intel 显卡。把 Xorg.0.log 贴上来吧

最后有一个 [WW] 说是 fall back 到了 vesa，看论坛的其他帖子说 vesa 是不支持混成的。
可是开机以后在 KDE 的系统设置 -> 桌面效果里面，混成类型选项并没有灰掉，点一下应用就正常了（要换一下混成类型，因为不换的话，应用按钮是灰的）。
