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，视频会显示，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 端口可以完美运行。

我尝试安装nvidia-331驱动程序，但是 Gnome 在重启后无法加载，所以我不得不删除它们。

我无法截取正确的屏幕截图，因为print screen按下时显示屏会自动修复。但这里有一个蹩脚的尝试来捕捉这种行为：

蹩脚的屏幕截图

更新1：

我按照下面 Fabby 的回答，从 xorg-edgers ppa 安装了 nvidia-346。

nvidia 驱动程序gdm加载失败。系统日志包含以下错误：

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 acpid: client 3187[0:0] has disconnected

更新2：

使用 Unity 和 XFCE 进行了同样的测试，同样的问题再次出现。Gnome 似乎与此无关。

答案1

我遇到了同样的问题，但我添加了http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu而且他们解决驱动程序问题的速度比标准 Ubuntu 存储库快得多……

我目前已安装 346.16 驱动程序，这消除了所有闪烁问题......
