我正在尝试将 Windows 替换为我的主要桌面操作系统。这是迄今为止我为 Ubuntu 安装的最复杂的硬件。我正在运行完全修补的全新安装的 Ubuntu 22.04
Linux MarkDesktop 6.2.0-33-generic #33~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Sep 7 10:33:52 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
我有一块 AMD Radeon HD 6570 显卡,连接了 4 台显示器。2 台 HP 24uh 显示器工作正常。get-edid 找到了 Dell 2007FP,但 Viewsonic 没有提供 edid 数据。到目前为止,我只尝试将 Dell 的原始分辨率设置为 1600X1200。目前限制为 1024X768。

我已经尝试了“模式 0”以及“gtf 1600 1200 60”的输出

所有这三种模式均作为新模式添加:
