我正在尝试将两个外接显示器连接到我的笔记本电脑通过Selore&S-Global USB C 转双 HDMI 适配器。
它与 Windows 配合得相当好(在几次初始断开/重新连接事件之后它变得非常稳定),因此硬件兼容。
xrandr 检测监视器并且它们在设置中可见。
有时启动 Ubuntu 22.04 时,显示器最初会启动,但随后开始断开连接并重新连接,最终变黑。在此期间,笔记本电脑会间歇性地冻结,直到拔下适配器。
我的笔记本电脑使用集成 Intel UHD Graphics 630(Thunderbolt 3 USB 3.1 Gen 2)以及 NVIDIA GeForce RTX 2070 Max-Q。我将适配器插入 Thunderbolt USB-C 端口。
% sudo lspci | grep VGA

我看到此错误在dmesg
输出中重复出现:
