SublimeText 使用 Unity/nVidia/Xinerama 变成黑洞

我最近升级到了 14.04，经过一番努力，我的 4 显示器设置终于“正常工作”了。但是，一些应用程序（我注意到 gedit 和 SublimeText）在失去焦点时整个窗口都会变黑。一旦变黑，我就无法让它再次显示，除非重新启动应用程序。需要说明的是，这会使应用程序无法使用。

我的设置是在 Quadro NVS-450 上使用 nVidia 专有驱动程序版本 331.38。下面是我的 xorg.conf 文件，后面是 的输出/usr/lib/nux/unity_support_test -p。您知道这里发生了什么吗？

编辑：看起来是内存问题，xinerama 让我的两张卡在三台显示​​器上耗尽内存。有些人设法通过在 BIOS 上增加共享内存大小来解决这个问题，不幸的是我的卡不是集成的，我没有这个选项。

同样的问题，Firefox 和 Thunderbird（以及其他应用程序）都有这个问题，焦点丢失 = 黑窗。

两台 GeForce 8400 GS 配备三台显示器。

问题在于驱动程序的 xinerama，因为您必须在 xorg.conf 文件中手动启用 Composite 才能使 unity 正常工作。

回到 nouveau 驱动程序可以解决这个问题，但你会遇到其他问题，例如持续冻结。
