No mouse in Vim inside nested screen sessions

Question

For many reasons, I often work with nested GNU Screen sessions. But Vim, running in a nested screen instance, doesn't seem to catch any mouse info. I've tried :set mouse=a and :set ttymouse=xterm2, the tricks that normally get Vim recognizing the mouse, to no avail. Any pointers? Or...cursors? Help please!

Mouse is not supported in screen. You can try tmux with those conf:

set -g mouse-resize-pane on
set -g mouse-select-pane on
set -g mouse-select-window on
