Xorg slow down rquires a kill

[Michael Havens]

I've noticed that after about 2-3 weeks of not shutting off my computer that 
things grind to a halt and that I need to kill Xorg.  Is there anything I can 
do or is it just my old k6 processor and I'll have to live with it? 

(yes.... I'm still running my computer that was built in 97 - I've replaced 
the power supply once and added all the memory I can..... it is only a little 
slower than my satelite notebook that runs windows) (it is great- my dad gave 
me the satelite not working and I discovered the MBR was messed up.... which 
I fixed with linux)
