14.04 – Nvidia HDMI问题
我在Ubuntu 14.04上运行Gnome-shell 3.10当我将显示器连接到HDMI端口时，会显示video，但鼠标移动和打开窗口会导致一些奇怪的剪辑效果。 将同一台显示器连接到VGA端口可以很好地工作。

我尝试安装nvidia-331驱动程序，但有了它们Gnome重启后无法加载，所以我不得不删除它们。
我无法拍摄正确的屏幕截图，因为按下print screen时显示屏会自动修复。 但这是一个蹩脚的尝试捕获行为：
Update1：
我按照下面的Fabby的回答，从xorg-edgers ppa安装了nvidia-346。
随着nvidia驱动程序gdm无法加载。 syslog包含以下错误：
Nov 18 22:31:03 gdm-simple-slave[3182]: GLib-GObject: g_object_ref: assertion 'object->ref_count > 0' failed Nov 18 22:31:03 gdm-launch-environment][3195]: GLib-GObject: g_object_unref: assertion 'G_IS_OBJECT (object)' failed Nov 18 22:31:03 gnome-session[3249]: Gdk-WARNING: gnome-session: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.#012 Nov 18 22:31:03 gdm-simple-slave[3182]: GLib: Source ID 4 was not found when attempting to remove it Nov 18 22:31:03 gdm-simple-slave[3182]: GLib-GObject: g_object_unref: assertion 'object->ref_count > 0' failed Nov 18 22:31:03 acpid: client 3187[0:0] has disconnected
UPDATE2：
使用Unity和XFCE进行相同的测试，同样的问题再次出现。 Gnome似乎是无关的。
我有同样的问题，但我添加了http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu ，他们更快地解决了驱动程序问题，然后是标准的Ubuntu存储库……
我目前安装了346.16驱动程序，它消除了所有闪烁的…
