apm and acpi -> battery status problem


Hi!

I've compiled a new kernel with both acpi and apm and my battery status indicator in gkrellm doesn't work anymore. Apm won't load cause of acpi:
Code:
dmesg -> APM: overridden by acpi
So I wonder if there is a way to check battery status with acpi. I compiled ac-adapter and battery support into the kernel. If not how to load apm instead of acpi.

Thanks in advance!

Check if /proc/acpi/battery/ exists. If it does, you can check the battery status by going deeper into the directory until you find a file called "state". To read it, simply execute "cat state".
If you don't have this, then maybe your laptop BIOS does not support acpi, in which case I would recompile the kernel with apm support only.
If you DO have acpi support, then I'd recompile the kernel without apm support.
Untill then, you could try disabling acpi by using the boot options "apm=on acpi=off", but this is not ideal. Here you can find more info.
