I have a problem using 2 mice. The serial mouse is the right speed for me under X and console, but the ps2 mouse is too slow under X but is fine at the console (I set the resolution up for the ps2 mouse with gpm) I'm starting gpm through debian's init script my config file: device=/dev/ttyS0 responsiveness= type=ms append="-3 -l \"a-zA-Z0-9_.:~/\300-\326\330-\366\370-\377\" -R msc -M -m /dev/psaux -3 -t ps2 -r 25 -B 321" apparently, the responsiveness isn't repated. i'm using gpm v1.19.6 debian v10
