Greetings,
As I get further into the configuration of my new machine I've hit some
minor snags. Perhaps someone here knows how to resolve these issues:
1) The machine does not cleanly shut down with the rt kernel. The system
appears to go down, but the power light remains on and does not turn off
manually (this happens with the battery in or out). Any fix for that ? I
don't like having to switch off the power at the strip, I doubt that
it's good for the box.
2) Is there a way to permanently disable the touchpad ? It's annoying to
have to turn it off manually (i.e. from the GNOME Control Center) every
session.
3) Related to 2: How can I keep the Control Center's touchpad dialog
from changing my Fluxbox background every time ?
4) Not really a problem, but: What's a recommended wifi card for a Linux
notebook ? And will the Atheros driver in 8.10 work or is it broken ?
Ubuntu 8.10 (Intrepid Ibex) is working nicely here. I'm waiting for a
fix to Ardour SVN sources so I can compile Ardour 3 (my GTK is too new
!), but otherwise it's fitting all my needs, thanks again to the great
assistance I've received here.
Best,
dp

i can't help with your other questions but this could a consequence of
having the "acpi=off" and/or "noapic" set in your kernel bootloader
config.
i don't remember which one disables the auto-power-off, but this is
definitely the observed behaviour on my box. i have to physically switch
it off after it shuts down.
i set these boot options because they help with the way IRQs are
allocated, which in turn allows better real-time performance.
all the best, G.

Btw, I upgraded the GNOME Control Center, it no longer replaces my
Fluxbox background. :)

It could also be that there was a kernel oops or bug while the machine
was running that left it in a state where the kernel can't finish its
own shutdown, I've seen it happen.

I guess it depends on how your mobo assigns IRQs in the first place.
For me it was a necessity: setting the above options reduced the actual
number of IRQs in use and ended the "doubling up" of IRQs with my
soundcard.
I can live with flipping the switch : a small price for good rt performance.

Result! Fluxbox rox!

I have to set acpi=off to get anything to boot up, otherwise the machine just
locks up when getting to starting X. Some of the distros on this machine will
not shutdown completely, and I also have to set acpi=force, which results in
the machine shutting down completely, and quite abruptly.
I havn't a clue about ACPI, and the man pages don't say much. This is on a PC,
not a laptop as you have, but it may be worth appending the kernel line with
acpi=force, and see how it goes.
Just a suggestion.
