I have installed Ubuntu 8.10 on a laptop HP Compaq nc6220. I have to
say it is from far the best release of Ubuntu until now. Everything
is detected and working. Thank to the ubuntu team the did a real good
job.

Since nothing can be perfect. I have from time to time an abend from
compiz. It happenned 3 times during periods where I'm not at the
computer. It seems to be related with the fact that a component of
compiz try to use APM. APM is not used on that machine but rather ACPI.

I have the following message in my log:
---------------------------------------------------------------

my video card is:
VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML
Express Graphics Controller (rev 03)

The video driver is intel_agp.

Everything there was installed natively at the installation. All I
have added is the "restricted" package.

Anybody would have a clue of how to solve this ?

This is rather inconvenient, since I use this machine from work with
ssh and sometime lose connection because of that problem.
