Hellos,

I'm running Fedora Core 2 from my HP 4560us laptop. I have a dilemma grrrrrrrrrr. I noticed from the first time I ran Linux on this system that it runs slow as snails unless I use "acpi=off" as a boot option. Unfortunately, with ACPI off I don't have access to all my nifty laptop power features like hibernate and suspend mode. How do I keep my system running fast while keeping these nifty functions? Also, I can't seem to change the brightness of my LCD screen. These issues are probably related. Well, any help would be greatly appreciated.

Thanks,
Brandon

Your lemma is a dilemma ;)

And knowing the make and model and the
kernel version you're using may help in
assessing it...

Of course, I'm sorry. I'm running Fedora Core 2 with a personally compiled 2.6.8 kernel. I didn't touch the ACPI or APM options when I sutomized the config though. The first kernel I compiled I tried playing with those settings but it prevented the kernel from even loading. Im using a Pavilion ze4560us which runs an AMD Athlon 2500+ and I believe an ALi chipset. Cruddy ATI 320 IGP (Which I also haven't been able to get to run at 100%). Thanks for the quick response though :-)

Is the problem specific to 2.6 kernels, or does it also
happen with a 2.4?

This fellow seems all happy with the 2.4 install
on his Pavillion.

ditch the APM stuff, and enable all of the ACPI options; also, there's a function somewhere related to 'broken BIOSs' that take huge amounts of CPU resources to service certain ACPI queries... so check on any power management and/or cpu frequency daemons you have and see what they say about those kinds of options
