Occasionally when i reboot my computer my mouse cursor is so laggy its unusable. This happens immediately on boot because even my cursor in SLiM is laggy. My only solution is to keep rebooting until it goes away. I've tried messing around with my daemon line in rc.conf by taking away slim, un-background them (syslog isn't ever backgrounded obviously), and disabling others but i don't really think this is the problem as it happens (seemingly) randomly. Sometimes one reboot is all it takes, sometimes 3+.

First, lets try to see if the kernel gives any output errors for the mouse.
dmesg | grep -i mouseOffline
dmesg | grep -i mousegives me:
input: Macintosh mouse button emulation as /class/input/input0
mice: PS/2 mouse device common for all mice
input: Microsoft Microsoft 5-button mouse with IntelliEye(tm) as /class/input/input6
input,hldraw2: USB HID v1.10 Mouse [Microsoft Microsoft 5-button Mouse with InteliEye(tm)] on usb-0000:00:id.2-2idk what the macintosh mouse is about, i have the microsoft 5 button
and just to be clear, when i say "laggy" i mean that moving the mouse around at normal speeds causes it to jump around like its only updating a few times a second. If i move the mouse very slowly then its less jumpy but still unusable.

Sounds like a hardware issue, did you try using another mouse?
You might also want to try turning off the "Emulate3Buttons" option in the xorg.conf file by setting it to false. Usually the problem could be because of the buttons, not the mouse movement.

Thanks a bunch Acecero, your suggestion has led me to find out that the usb ports on my computer are breaking. When i switched to a different usb port, mouse movement was flawless. Interestingly this hasn't happened in windows but i suppose that's just because windows gets such little use here (only need it for steam).

I experience the same problem from time to time. Dmesg says something about a failed IRQ:
