![XRandr 可能的配置 Ubuntu MATE 16.04](https://linux22.com/image/993000/XRandr%20%E5%8F%AF%E8%83%BD%E7%9A%84%E9%85%8D%E7%BD%AE%20Ubuntu%20MATE%2016.04.png)
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

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

答案1
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
