cpufrequtils and libcpufreq0 cause problems on the NB30

Postby turbolad » 25/09/2010, 22:00

Hi, having just re-installed Ubuntu Netbook Edition twice due to poor performance with flash player and flash kept crashing, I discovered that when you install the cpufrequtils and libcpufreq0, that's when the NB30 becomes slower and the problems arise.

Anyone know what the "cpufrequtils" and "libcpufreq0" are supposed to do? I've had to untick the "voira" ppa so I don't install them things by accident. The NB30 works much better without them installed.

"cpufrequtils" is installed as a dependency with the modified kernel on my repository.
It's needed because the modified kernel has the 'acpi-cpufreq' driver compiled as a module instead of being included into the kernel, in order to allow it to be replaced at runtime by the PHC module for the users that want to undervolt the CPU.
The problem is, when the 'acpi-cpufreq' driver is compiled as a module it's not automatically loaded at boot, so "cpufrequtils" is used to load it automatically.

Ok, bit technical to me lol - I'm still a Linux newbie, but learning fast. :lol:

I found those things in the updates, installed them and the NB30 slowed down and flash videos become juddery. I re-installed Ubuntu Netbook Edition, this time I did not install them things and it's working fine.

Thanks for your hard work. With your help, I'm happily using Ubuntu on my netbook instead of Windoze. Cheers. :) :D
