When I switch my old adventure games in ScummVM under Archlinux to fullscreen mouse becomes too sensitve. This is the case with my laptop’s Synaptics touchpad and googling around I’ve found that other people have this issue too. Solution is pretty simple, and I found it on Ubuntu forums. In console window type:
export SDL_MOUSE_RELATIVE=0 scummvm
To make it easier for me I’ve created simple script that I run instead of ScummVM binary.
cat /usr/local/bin/scummvm.sh #!/bin/bash export SDL_MOUSE_RELATIVE=0 scummvm
