XRandr 可能的配置 Ubuntu MATE 16.04

我正在检查 XRandr，并且我运行了它，它在其中一行显示了这一点：

Screen 0: minimum 8 x 8, current 1366 x 768, maximum 32767 x 32767

这是否意味着我可以将其配置为最大 32767 x 32767 像素？

它可以在 HDMI 中使用 1080，但在笔记本电脑显示器上可以实现吗？

我设法添加了虚拟显示器

这是 GTF 输出：

gtf 1920 1080 60 -x

# 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz
  Modeline "1920x1080_60.00"  172.80  1920 2040 2248 2576  1080 1081 1084 1118  -HSync +Vsync

这是我在笔记本电脑屏幕上添加模式后得到的结果

xrandr --addmode LVDS1 1920x1080_60.00
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)

这是我现在的 XRANDR 输出

显示的最大分辨率xrandr是最大虚拟屏幕尺寸的分辨率。

我能找到的最能帮助您解答问题的信息是：

https://pkg-xorg.alioth.debian.org/howto/use-xrandr.html#_placing_outputs_in_a_virtual_screen

片段：

Let’s have a look at the maximal virtual screen size, we see 4096x4096 in this example:

$ xrandr|head -1
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 4096 x 4096

With DRI and without KMS, that might be needed. Indeed, drivers will often create a default virtual screen with small dimensions, for instance 1600x1200, to reduce memory consumption.

If you plan to use multiple outputs displaying different zones, you should configure your xorg.conf by adding a Virtual line to the Display subsection in the Screen section.

Section "Screen"
  …
  SubSection "Display"
    Depth 24
    Virtual 3000 2000
  EndSubSection
EndSection
