Ubuntu20.04LTS英特尔NUC11的4K图形问题
提问于 2021-09-17 08:00:02
我最近买了一部英特尔NUC11 i7。当使用3840x2160 @60 at的监视器时，我一直无法获得稳定的图片。当屏幕上有任何运动时，屏幕每隔几秒钟就会打开或关闭一次。
如果我把分辨率降到2560x1440，或者把刷新频率降到30 or，我就会得到一张稳定的图片。
相同的硬件工作在完全分辨率/刷新率与Win 10完美。
我一直与英特尔的客户支持(谁正式支持20.04LTS- https://ark.intel.com/content/www/us/en/ark/products/212516/intel-nuc-11-pro-kit-nuc11tnhi70q.html)的房子。他们已经没有想法了，现在只是在说“如果它能与windows一起工作，机器就可以了，所以是Ubuntu的错”。
我可以证实以下几点：
- Bios被更新为最新版本；我还重新安装了bios (由英特尔建议)。
- i7处理器；16 i7
- 电缆肯定是正确的，事实证明，它与Windows完美地工作。我尝试过监视器/nuc上的多个电缆和端口。
- 已经尝试过HDMI和显示端口。
- Ubuntu的清洁安装
- 已经尝试了Ubuntu的最新版本(21.04)，加载了usb卡，问题依然存在。
- 在Bios中，我将IGD最小内存和IGD孔径大小设置为最大值(由Intel建议)
- 我运行
xrandr --auto是为了关闭“幻影显示”(由英特尔建议) - 将视频模式手动设置为bios中的hdmi (由Intel建议)
以下是英特尔请求的系统信息的转储：

我有完全相同的问题，我必须注册一个帐户在非盟，只是为了增加这个答案。
我的系统也是NUC11 i7。我最初的安装是Fedora，在4k/60 at工作时，我在HDMI连接中遇到了随机断开的问题。
我认为这个问题与内存安装有关。
通过以下尝试，这个问题仍然存在：
- 用Ubuntu取代Fedora
- 将BIOS升级到最新版本(编写此版本时为041)
- 使用USB-C进行HDMI或DP，无论是前后USB-C。
- 尝试不同的BIOS视频存储器配置
但是，有趣的是，在我添加了一个额外的RAM带之后，这个问题就自动解决了。我最初的设置就像你的一样，只安装了一个16G的DIMM。
我希望能给你的问题加上一个评论，而不是把它作为回答，因为我不知道这对你的情况是否有帮助。
