Re: problem starting up kubuntu

It seems to be pointing the finger at "powernowd", so the first notion would be to kill that process. That process is not appropriate for a desktop system such as yours anyway.

So, to determine the process number of powernowd, at the command prompt (which is all you have, I guess) you would enter

ps -e

and note the process number.

Then, to kill it, do

sudo kill 12345

(assuming you had determined the powernowd was process #12345.

Then, you should be able to run

sudo /etc/init.d/kdm start

and run the X server. Once logged in to your desktop, go to KMenu>System Settings>Advanced>Services and open it, click the "Administrator Mode" button, and find the powernowd line. You need to highlight it, right-click and toggle it "off" so it does not start at boot.

HTH

BTW, if you ever get the itch to re-install, the 64-bit OS will run great on that CPU.

Re: problem starting up kubuntu

yeah it fixed it, but as soon as i re-enabled the ati accel. driver it starting the powernowd thing again. so i guess fix it again and not enable that driver?

Hmmmmmmmm -- why did I know it wouldn't be that easy!

I'm not proficient with the ATI drivers -- an early bad experience with a Radeon card drove me into the Nvidia camp, where I remain. But I'm little surprised at the notion that a video driver requires powernowd, which is a CPU frequency-scaling daemon.

I imagine you really need that ATI driver to get decent video performance. I would enable the ATI driver, then go back and disable the powernowd daemon, and see if the driver stays enabled. If not, I'm afraid you'll be spending time with Mr. Google tonight! :P
