升级到 15.04 后，图形 (geeqie) 速度变慢

前几天，我将 IBM Thinkpad T440p 从 14.10 升级到了 15.04。我注意到全屏图像查看真的速度很慢。以前geeqie（即在 14.10 及以前版本中）用数码相机图像绘制屏幕（1920x1080 外接显示器）基本上是即时的，但现在需要几秒钟，并且增量屏幕更新从左到右、从上到下逐块可见。这就像某些 X 服务器选项设置不正确，但我不知道可能是什么原因。

我正在运行 xfce4（现在和更新之前，已经运行了很长时间）。如上所述，我通常用于查看图像的应用程序是。除了查看图像之外，其他一切似乎都还不错；我想我没有尝试过通过或geeqie观看本地视频，但基于浏览器的视频似乎运行良好。vlcxine

听起来就像我忘记安装硬件加速驱动程序时发生的情况。通常是 ATI 的 fglrx 或 nvidia 的 nouveau。
