omg, the mouse is broken
 

i have a mcirosoft ps2 mouse and it doesnt work with the default ps2 mouse setting. all the other ones are serial and usb so how do i make my mouse work?

it goes all crazy and gets stuck in the corners and stuff whenever i move it in kde, but before i startx it works fine???

Depending on the distribution you are using, you may want to see if X is loading the correct parameters in it's config file. Go to /etc/X11 and edit XF86Config-4 OR if you don't have that XF86Config. Scroll down to the pointer section and if you could, put them up here, we could see why it's not loading correctly. Usually all you have to do is make sure that it's using the PS/2 protocol and the correct device eg. /dev/mouse.

im running slackware 8 and i dont have a directory called x11 in /etc. where else could the file with the mouse config be?
