Xorg to 99%, kdm ceases to work anymore
I have a new system at home that I've loaded a few times with Kubuntu 8.04 and I keep running into this same problem.
I leave my computer on for an extended period of time, I come back to it, the windowing environment is basically frozen but I'm still able to ssh to the box. I ssh in, run TOP and see Xorg taking 99% of the CPU, so I kill it and restart kdm and then kdm runs but refuses to be visible. The only solution thus far is to reload, which gives me 1-2 days before lockup again.
Also, now I'm forced to load my machine with the OEM option enabled and then apt-get update and apt-get upgrade before I can see a windowing environment.
My first instinct is video, I'm using an Nvidia 9600 GT 512mb rev a1.
Any advice for this problem or how to start deciphering it?
