I suspect there is a problem with 4363 as 4496 does not lock up X, just scrmbles the VT's. Regards Sid. Carlos E. R. wrote:

Went back to 4363, looked great, but X (and keyboard) lock up with garbled colour full screen after I've left it up for some hours, I then have to issue init 6 by ssh from another box, init 3 does not have any effect. I think I shall try some other values for NvAGP other than 0 and see what happens. Regards Sid.
Er... in this case, as the machine was left alone for a long time, it could be a screen saver that crashed badly. Or something related to sleeping.
If it does it again, instead of init 6, enter "top" as root, or have a look at "ps afx|less", and start killing tasks, one by one. Perhaps you could find the culprit.
