I see you were having even worse problems with this.  :(

I had the same kind of suspicion.

This laptop came with Vista installed, but I immediately replaced it
with Debian.  So I don't have a Windows trial period to compare with.

When I run glchess on my computer, the gnuchess engine actually goes to
100% (according to top), and the temperature goes up quite quickly.
sauerbraten only seems to need 60% or so, and doesn't overheat as
quickly (probably because the GPU is doing the graphics acceleration).

The package is called nvidia-settings, in the contrib section, and I
already have it installed.  But I don't know which settings, if any,
might help in this situation.

Wow.  Except for the part about writing a script, I have no idea about
how to do that.  Can you attach a copy of your script to the email (and
does Debian's list server forward attachments?) or can you upload the
script to a pastebin website or something?  That would at least give me
an idea of what commands I would need to use.

I'll definitely give that a try, like the earlier post suggested.  An
"industrial-grade vacuum cleaner" sounds like a floor-cleaning model,
so the same concern comes to mind about particles in the vacuum, though.

Hmm.  Maybe they have some of that secret technology you talked about.

Wish I could help with that.  Unfortunately, I'm in the US, where we know
very little about AltGr keys (or their combinations).
