我正在从联想 m700q (i5-6400T) 转移到 m720q (i5-9500T)。我尝试过克隆我的 22.04 安装并尝试在 m720q 上安装，还尝试过全新安装 24.04 nightly，但结果还是一样。在较新的硬件 (m720q) 上，两个 Ubuntu 版本的显示看起来都一样
24.04 的安装在安全模式 (nomodeset) 下运行良好，但重新启动后，屏幕出现像素化，分辨率很差，难以阅读。下面是来自这两个不同系统的两张图片 - 微小、清晰的像素来自 m700q，而分辨率较低、模糊的是 m720q。

我花了整个周末的时间搜索，但还是没有找到任何可以实现此功能的设置或选项。我怀疑nomodeset它能实现，但这样我就无法享受 GPU 加速的好处了。
屏幕是用于 Raspberry Pi 的 SunFounder 7 英寸 TFT 显示器，HDMI - 1024x600 高清 LCD 屏幕。我尝试将 HDMI 连接到另一个更大的屏幕，并且工作正常，那么这可能是 X 配置吗？我也尝试过将此配置用于 X11。
