I'm using X 4.4 on Arch Linux, kernel 2.6.6. I have Gigabyte nforce2 mb (GA-7N400) and have a MS Wheel Mouse Optical usb and ps/2 mouse.
I had it hooked up via USB, but couldn't get the mousewheel working. The true problem is when I moved the mouse too quickly or held ctrl and wiggled the mouse, it began to move erraticly and copy and move things about.
Yesterday I found a usb to ps/2 adapter, and am trying the mouse via ps/2. Now the mousewheel works, and when I hold ctrl and wiggle the mouse the slightest bit, it stops responding and I have to restart X.
During my struggles with the mouse via USB, i uninstalled gpm. Here are the relevant lines of my XF86Config-4 file:
Option "Protocol" "imps/2"
Option "Device" "/dev/input/mouse0"
Option "Buttons" "5"
Option "ZAxisMapping" "4 5"
Option "Resolution" "200"
Option "Samplerate" "200"
Does anyone have any ideas? It just happened again while I was pasting that in here. Oh, the joys of computing.
