I rarely get pyjamas. I do, however, get a completely blank screen
nearly every morning, needing a restart (sometimes 2 or 3) to wake up.
The restart is what occasionally provokes the pyjamas.
When the screen is blank, the NVidia card does not appear in the
*pcidevices list.
This is on a Panther with OS 5.11
With OS 5.09 I used to get the problem only occasionally (once every 2-3
weeks).
Our other Panther (OS 5.09, purchased at the same time but not upgraded)
has never shown this problem.
We also have an older X100 (also on 5.09) which used to have a similar
problem on earlier OS versions, but 5.09 cured it.
All three have the same video card model

I'm _very_ reluctant to mess with things at the moment though. I can't
take the chance of provoking any downtime right now on any of these
machines, so I'm just living with the startup problem.
