1) First make sure your are describing the mouse port as: /dev/ttyS0 NOT /ttys0
2) If you have installed gpm-frozenVer.deb, this update sets up to new mouse devices: /dev/gpmdata and /dev/gpmctl and more over,with WARNING sets /dev/mouse -> /dev/gpmdata (a Bug report has been filed) Thus if you enter /dev/mouse in XF86Config, it will try use /dev/gpmdata which might not suffice. It didn't on my laptop with ps2 mouse (/dev/psaux) Changing from /dev/mouse to /dev/psaux in XF86Config solved the X problem for me. MarvS ------------ Hey there again. I'm having problems setting up x with this serial mouse. It's an MS serial mouse. I specified MS mouse on ttys0. That's serial A right? I don't think I'm losing my mind. There isn't a map in fstab that I'm supposed to specify is there?
