我使用 TeamViewer 连接到 Ubuntu 主机。它的分辨率目前为800x600。我想将其分辨率更改为1024x768，但我收到此错误：
xrandr: Configure crtc 0 failed
命令如下：
xrandr --output Virtual1 --mode 1024x768
我已经寻找过解决方案，但没有找到任何解决方案。
结果xrandr --verbose是：

看起来，该1024x768分辨率是受支持的。为什么不可用？
我也尝试过arandr，但出现同样的错误。
其他分辨率也不起作用，只有800x600
的结果xtrace xrandr --output Virtual1 --mode 1024x768已上传：http://pastebin.com/AVnbDtQa
如果我运行xrandr --fb 1024x768它，它就会变得像素化，并且有些部分无法适合屏幕。
如果我运行X -configure我会得到这个错误：
(EE)
Fatal server error:
(EE) Server is already active for display 0

and start again.

Please consult the The X.Org Foundation support

如果可能的话，我想避免重新启动。
结果xrandr -d :0是：
