屏幕闪烁

我有一台 MSI GS60，配备英特尔 broadwell i7-5700HQ CPU 和混合显卡（nvidia GTX ‎970‎M）。屏幕闪烁非常严重，如以下视频所示（第 0:03 秒和 0:08 秒）：

我知道这不是硬件问题，因为这个问题根本不会发生在 Windows 10 上。我尝试了许多内核、许多发行版和许多驱动程序，但都无济于事。我现在正在使用 nvidia-352 驱动程序和 bumblebee。我甚至不确定这是图形问题、电源问题还是其他问题。任何帮助都将不胜感激。

答案1

您有一个非常新的 GPU，因此请安装并使用最新的官方稳定 NVIDIA 驱动程序 361。

替换bumblebee为nvidia-prime在两种图形解决方案之间切换。

卸载所有当前安装的 NVIDIA 软件并删除bumblebee。

打开终端并执行：

sudo apt-get purge nvidia* '^bumblebee.*'  
sudo reboot

当 GRUB 菜单出现时 - 选择 Ubuntu 条目并按下E键。

nouveau.modeset=0在Linux行末尾添加，然后按F10启动。

注意：Space在此行的最后一个符号和之间设置一个nouveau.modeset=0。

登录并从专有 GPU 驱动程序 PPA 安装 NVIDIA 驱动程序。

打开终端并执行：

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-361 nvidia-prime
sudo reboot
