Normally when i boot Arch on my laptop, it runs perfect, but when I boot without the power cable plugged in, it gets really slow. My games lag and compiz is really slow. So. Why is this?
It's probably worth mentioning that I'm pretty new to Arch.

Does this only occur when the cable was not plugged during boot? So plugging it in at runtime doesn't change anything? I think that some notebooks underclock the graphics card when running in battery mode.

Could be a power saving feature.
The day Microsoft makes a product that doesn't suck, is the day they make a vacuum cleaner.

But if they tell you that I've lost my mind, maybe it's not gone just a little hard to find...

Change your power-saving policy (cpu-frequency governer) from power-save or dynamic to Performance. There must be some GUI that makes it easy for you.

Have you considered that your battery may be a complete pile of shit?

A bad battery shouldn't cause it to run slow.
My bet is on some form of powersaving feature.

I haven't owned a laptop in a long time but I know that some of them have power management features that can be set via the BIOS. BeholdMyGlory, you might want to check there.

Exactly. To make it faster again I have to reboot with cable plugged in. But I don't think it has anything to do with the hardware or BIOS itself, since I could run Kubuntu without this problem.

Ok, I'll try that. You wouldn't happen to know the name of a GUI that handles this?

It probably is, but it shouldn't matter anyway.

I don't think that i should have to change anything there, seeing as i could run perfectly on Kubuntu even with no power cable plugged in.

You may want to 've a look at this http://wiki.archlinux.org/index.php/CPU … cy_Scaling.
On xfce, there is a panel plugin pkg called xfce4-cpufreq-plugin, which would make it much easier.
