➜ ~ My研究:
是的我更新了BIOS。
驱动程序已经加载,所以这不是我的问题。
我尝试了OEM内核,如建议的这里,但没有解决方案。见终端输出。
关于“错误CPU管道B FIFO欠运行”,我确实找到了一些关于c-状态的引导选项的线程。我试着降低这里中的建议和拱维基中描述的省电(c-state)。没有改善。
我按照建议从的ppa安装了这里的驱动程序。没有任何改进(警告:使用ppa-purge的“恢复到原始驱动程序”对我不起作用)任何内核。
我可以在我的显示器的菜单上禁用"HDMI超高清深颜色“,然后Linux就会切换到30 HD,并对像素进行粗略的绘制。
遗憾的是,我无法用Linux尝试5.14内核,因为在适当的版本中没有一些c编译库(我只是忘记了名称)。

你能在图片中看到的是:
感谢您的阅读!任何关于细节的问题都是欢迎的。-)我认为,该机器上的4k还没有在标准Ubuntu系统上运行。希望我们能让这个流行的硬件运行起来,就像windows一样。;-)

我和你有同样的问题。尝试使用显示端口,它为我修复了它。您的HDMI版本仅为1.4b (https://www.hdmi.org/spec/hdmi1_4亿)。这个版本不支持4k@60 4k。
有许多HDMI到显示端口适配器在那里。
