Cinnamon's annoying message: "window is not responding"
I use the cinnamon desktop manager, and due to the nature of the things I do, I frequently get the error (window) "XXX is not responding.". Almost always, this is just the result of having a GUI that is only active at certain points in time, or the program being debugged.
I got the problem fixed following the instructions I found in this link. To disable the responsiveness check, you can run:
dconf write /org/cinnamon/muffin/check-alive-timeout "uint32 0"
To verify that it worked, you can run:
dconf read /org/cinnamon/muffin/check-alive-timeout
