Tel*_*Why 14 xrandr error-handling debugging display-resolution
尽管有相当多的用户拥有这些错误,但我还没有找到解决此类错误的单一方法。
所以我想尝试自己找到解决方案。但是,我不知道它们为什么会发生......
有没有人知道为什么?您不必说明为什么会出现每个错误,只要有一个就好了!

比我想象的要复杂得多,因为我尝试使用xrandr

故障排除确实是一个很大的堆栈,旧硬件和滚动专有驱动程序更新更加困难,即使 DB-15 VGA 电缆(或廉价电缆)中的针脚接触不良也会产生影响。实际上,我在 Ask Ubuntu 中读到的大多数问题都是关于监视器丢失/错误的 EDID数据,归咎于:电缆(kvm 交换机/连接适配器)。您可以从xrandr --verbose
输出中很快注意到这一点。
在许多情况下,驱动程序也会因为来自监视器的不完整/部分错误的 EDID 数据(制造商错误)而限制某些模式,用户通过编写自定义xorg.conf
覆盖来克服这个问题:模式、HSync 和垂直同步、EDID、DPI ...取决于驱动程序(nvidia
对于例如可以从监视器忽略EDID)
我建议高级用户或在此处提供帮助的用户阅读此内容:
阅读旧文档和提供解决方案的帖子时要小心。更好的是查找正在使用的特定驱动器的文档。
KMS
,DRI
或fb
(framebuffer) 驱动程序类型。(请注意,我不是专家)。xorg.conf
默认情况下不会创建。即使用户制作了一个,他/她也不应该创建所有部分,而应该只覆盖需要的部分。这是一种即时配置。在xrandr
似乎不知道什么驱动程序是否能够或同意提供(所有驱动程序的功能),而Xorg的是它们之间的接口。所以以下任何一种情况都可能发生:
因此,当 Xorg 或 Driver 无法处理或拒绝 xrandr 请求时,我们会收到这些错误:
xrandr
为什么?我在这里查看了许多与xrandr
& resolution相关的问题,他们缺少有关完整堆栈设置的很多信息。考虑集只提到了最后一个失败的命令。甚至,我建议将完整的输出放在问题中,以便我们可以搜索相似之处并将相关问题联系起来。

由于 EDID 验证,驱动程序拒绝时产生的错误。nvidia 驱动程序删除了一些模式,我注意到在启用“ModeDebug”之后。任何一个:
- 显示器的 EDID 数据并不完美
- 驱动程序在处理 EDID 方面不稳健
- 生成的模式条目不在 EDID 中声明的监视范围内
Case (1 & 2) 解决方案是自定义覆盖 Hsync/Vsync/PixelClock 或完整的本地 EDID 文件,一些驱动程序可以忽略 EDID。

有些情况只需将 vsync 稍微降低一点就可以解决,例如
1280 800 59.80
。然后,如果双显示器与不同的 vsync 一起使用,可能会在一个屏幕中看到循环行为(例如每 15 分钟空白 3 秒)。这是因为如果它使用标准的 60Hz,则与其他屏幕有 0.2Hz 的差异。无论如何,这个问题可能已经随着新的高级多头适配器和 4K 屏幕而消失。解决方案:更改为所有连接的显示器支持的确切频率,删除不兼容的显示器。(根本原因,可能是一些廉价的显示器芯片是为电视设计的)
