x2go resolution from windows client

Question

I'm happily using x2go to connect to a remote Ubuntu Server 16.04 with XFCE installed from my local pc with a local resolution of 1920x1080 on a HiDPI screen (13''). If I run the x2go client from a virtualized Linux (Linux Mint 18.03 with XFCE), everything works well and I can see a really sharp image of the remote desktop. Problem is, when I try to connect directly from Windows 10 the image is blurred and the resolution is wrong. I tried to play around with the x2go client settings but no way, the image is always terrible. I also tried to use PyHoca and different X-servers but the result is the same.

Is it a well-known problem? Any suggestion on how to fix it?

Thanks in advance.

Answer 1

I had a very similar problem: A Dell laptop with an Nvidia graphics card, having a resolution of the built-in flat panel of 1280x800. I connected this to an external screen with HDMI with a resolution of 1920x1080. However, X2Go seemed to pick up the resolution of the built-in screen instead of the actual screen, making everything seem blurry (interpolating 1280x800 to 1920x1080).

This is what fixed it for me: Navigate to the C:\Program Files (x86)\X2GoClient\VcXSrv\ directory in Explorer. Select the vcxsrv.exe file and right-click it, choosing Properties from the popup menu. Go to the Compatibility tab, and in the Settings section there, select the option "Override high DPI scaling behavior. Scaling performed by:" and then select "Application" in the combo-box below.

Restart the X2Go Client to have its X server start with this new setting.
