我在运行 Ubuntu 20.04 的机器上遇到了亮度闪烁的问题。我的机器是双启动的，这仅在我使用 Ubuntu 时发生。
我看到很多其他帖子都在谈论类似的问题，但没有一个解决方案对我有用。我已经录制了闪烁的视频（见下面的链接），希望能帮助缩小答案。

有没有人见过这个问题？我目前在联想 Yoga 730-15ikb 上双启动
我似乎有 50/50 的机会，当我启动时，我的屏幕会每隔 5 秒左右闪烁/闪烁一次。如果它要闪烁，它会在笔记本电脑启动时启动，我想是在加载图形驱动程序时，因为您可以看到使用时加载的命令的屏幕亮度差异GRUB_CMDLINE_LINUX_DEFAULT="text nouveau.modeset=0"
我的系统无法使用 nouveau 驱动程序启动，因此我禁用了它并尝试了推荐的 440 驱动程序以及 435。我目前正在使用 450 NVIDIA 驱动程序，它是唯一可以与 x 服务器软件一起使用的驱动程序。所有三个驱动程序都有相同的闪烁问题。
我试过用同样的问题进行全新安装，并尝试将内核更新到 5.8rc7。
我唯一的解决办法是重置笔记本电脑。

我使用这些说明在我的 Razer Blade 15 上设置了 Ubuntu 18.04，2019 年中，Nvidia 2060 RTX GPU
除了WIFI之外，一切都很好。
但是当我尝试将其连接到 HDMI 设备时，屏幕（随机）开始闪烁。我使用过许多其他设备来观看电影或在外接显示器上做一些工作。第一次尝试设置 Ubuntu 时，我遇到了这些闪烁问题，但重新安装后它们就消失了。
由于我现在使用笔记本电脑几个月了，我正在寻找一种方法来解决这个问题，而无需备份和重新安装所有东西。
我尝试了几种方法来更新或重新安装 nvidia 驱动程序，但到目前为止都没有达到预期的效果。
但正如你所见，我的系统甚至无法正确检测到我的显卡型号

之后，我今天尝试卸载并重新安装所有与 nvidia 相关的软件包，包括 cuda 和 libcudnn 使用这个. 之后我有一些未满足的依赖项，我尝试使用这些依赖项进行修复
sudo apt-get remove --purge nvidia-* -y
sudo ubuntu-drivers autoinstall
看起来一切都很好，nvidia 驱动程序都已正确安装和加载，但重新启动后我立即恢复了屏幕闪烁。
我猜这可以正常工作

当前加载的驱动程序是 nvidia-driver-440-server，因为它是我的系统推荐的，并且屏幕闪烁很严重

当我禁用 NVIDIA GPU 并改用 Intel GPU 时，一切都很好，没有闪烁。因此，我认为我的驱动程序安装存在一些严重问题。
有时通知栏中也会出现错误，很遗憾我无法复制和粘贴。但它们都与“nvidia-smi”相关。
非常感谢任何帮助，我对 linux 比较陌生，因为这是我第一次认真使用它作为操作系统。如果我可以通过提供信息以任何方式提供帮助，请告诉我。
编辑：
经过几个月的反复试验，我终于可以解决问题
xrandr --mode 1920x1080 --rate 59.97
我的笔记本电脑有 144Hz 的能力，但这似乎对他来说太过分了，降低刷新率解决了这个问题
我感到有点松了一口气，但也有点愚蠢，一个 linve 解决了几个小时的挣扎和阅读/写作论坛帖子无法解决的问题
我有一个带有 Intel 集成 (Ivybridge) 显卡的 Ubuntu 18.04 桌面。当我启动系统时，登录屏幕和默认的 Ubuntu 会话显示严重扭曲的图形和颜色，使其几乎无法使用。图片附在下面。
但是，我在这个系统中也安装了 gnome flashback (metacity) 和 xfce4 桌面，当我登录到这些会话时，除了少数应用程序（google-chrome、skype 等，我还没有检查所有），显然没有如此严重的失真应用程序虽然）。到目前为止，鹦鹉螺和其他应用程序在这些桌面上运行平稳，没有任何故障。有没有办法解决 Ubuntu 会话和登录屏幕的问题？我尝试了以下链接中提到的一些解决方案，但没有成功 -

我对这个论坛很陌生。如果我能得到任何帮助来解决这个困扰我很长时间的问题，我将不胜感激。
非常感谢。
当我启用分数缩放时，我的主显示器上出现鼠标光标闪烁。我在带有 Intel UHD620 显卡的 Dell Inspiron XPS 9380 上运行 Ubuntu 20.04 桌面。
我有一个双显示器设置，因此，我的主屏幕上有 200% 的缩放比例（13 英寸到 4k），我的第二个显示器上有 100% 的缩放比例，它位于桌面上方并扩展了桌面（“加入显示器”） . 为了实现这种配置，我在设置 GUI 的屏幕显示选项卡中启用了分数缩放。
缩放正是我想要的，但是，光标仅在主显示器上非常快速且不规则地闪烁。使用任何程序时，它看起来令人不快并且非常分散注意力。单击功能工作正常，尽管闪烁，光标仍能完美平滑地跟踪。
我无法通过在命令行中使用“xrandr”来实现相同的显示配置，因此理想情况下，我将继续使用 GUI 中可用的小数缩放设置。
几天前，我用 Ubuntu 18.04 和 Windows 10 双重启动了我的笔记本电脑。我的笔记本电脑是戴尔 Inspiron 5567、8GB 内存、1TB 硬盘和英特尔高清显卡。所以，开机后，笔记本电脑屏幕突然闪烁，然后笔记本电脑进入睡眠状态。我不知道为什么会这样。任何帮助，将不胜感激。
我刚收到我的新 xps 13 9380，它有 4k 显示器并预装了 ubuntu，自从我开始使用它后，我就遇到了闪烁的问题。
这里的视频：

这可能是 ubuntu 配置问题还是我应该向戴尔报告显示故障？
检查 BIOS（版本 1.2.1 - 最新）后，它可能是 ubuntu 配置问题，因为没有闪烁，所以硬件很好。
我最近升级到 Ubuntu 18.04，但我遇到了微妙的（但持续不断且相当烦人）的屏幕闪烁。我的电脑是 HP Envy x360 Convertible 15-bp1xx；使用英特尔图形驱动程序。闪烁并非特定于任何应用程序，但在大的中灰色区域（例如具有深色主题、桌面背景等的应用程序）中更为明显
