I am using a Macbook Pro (16-inch 2019, OSX 12.6.5) with X2go to connect to a remote Linux unit. When I connect my Macbook to a secondary display, using the "extended display mode", XQuartz opens an extremely wide window, which roughly covers the size of my two combined displays (main and extended). I am not able to re-size this XQuartz window, nor have I found any setting to put a limit to/regulate the dimensions. I have read this thread (Unable to resize windows on split full screen in MacOS Mojave when using external monitor) but apparently, I am not able to split the screen with another app because XQuartz immediately hides its window. Do you have hints/suggestions?

Thank you very much!

  • Just a guess, but resizing is not possible because the size of the window has to be proportional to the resolution of what the Xserver is using.

Apple menu > System Settings, then click Displays in the sidebar, then change resolution from Default to More Space.
