我目前在 Elementary OS Freya 上运行（基于 Ubuntu 14.04）
每当我尝试添加窗口捕获时，OBS 就会崩溃。

答案1
我认为您面临的问题可能是由于图形驱动程序不匹配或可能需要。
看起来您正在使用 bumblebee（针对 NVIDIA 的 Optimus 技术）来启动。
尝试此操作需要您自担风险。
首先弄清楚你有什么显卡。
lspci | grep VGA
这表明我正在使用“NVIDIA Corporation GF116M [GeForce GT 550M] (rev a1)”所以它是 NVIDIA
然后从 xorg-edgers PPA 安装它。使用最新版本。
sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-cache search nvidia
Find the latest one (at time of this writing was 352)
sudo apt-get install nvidia-352
sudo apt-get install nvidia-352-updates
在此过程中，我摆脱了 Noveau，并从 xorg-edgers PPA 安装了 NVIDIA 驱动程序。 obs在那之后推出得很好。
然而，屏幕时不时就会冻结，我计划在此基础上探索使用大黄蜂，看看是否有任何变化。
祝你好运
注：直接从NVIDIA获取安装NVIDIA驱动失败
