    I have an Ubuntu 18.04 client and connect to a 18.04 remote KVM machine (virtual display) using the free NX version.  I have the setting set to match the display resolution of the client, which is my second monitor @ 2560 x 1440.  However, when the connection is made the remote resolution changes automatically to 2048 x 1152, which of course makes the experience grainy/fuzzy.

    I have set the resolution to  custom as shown below, but it doesn’t change things.

    Ok, I resolved the issue.  When I checked the console on the VM, Ubuntu 18.04 did not have a 2560×1440 resolution to select.  So I followed https://www.bonusbits.com/wiki/HowTo:Add_Missing_or_Custom_Display_Resolution_on_Ubuntu and added it as follows.  Now NX works fine @ 1560×1440.
