[wellylug] Ubuntu on laptop

[Bill Christiansen]

I'm trying the new Ubuntu distro on my laptop and it's quite impressive
but I have a strange problem. I noticed it's performance was excellent
from a cold boot but after running for some time it would intermittently
get extremely slow. What I think is happening is power management puts
the cpu into sleep mode but it's not waking it up properly so it only
runs at about 10% of it's normal throughput (apps will load if you wait
long enough but it takes for ever). Acpi doesn't get loaded due to the
age of the bios but I put apm in the /etc/modules and that loads and the
laptop battery monitor stuff works fine. I had a look in the bios but
there's no way to disable the cpu's sleep mode.
