Fix high CPU usage in Ubuntu 9.04 Jaunty

I upgraded my laptop to Ubuntu 9.04 Jaunty in the hope that it would fix the “I have no memory of your last session” problem that 8.10 introduced. Everything went smoothly, and everything seems to work well.

Except one thing.

The CPU utilisation was 100% on one core. I’m lucky this is a dual core laptop, or the thing would likely be unusable.

It turns out that the problem was the remote desktop process: vino-server. Killing vino-server meant that the Xorg process was no longer chewing up 14% CPU (according to top) and made the CPU usage drop back to next to nothing when idle. As it should be.

I found the hint at this thread in launchpad. I hope this tip helps you if you have this problem. I doubt I would have figured it out on my own, so here’s to the power of the internet and sharing information!

  1. I had the same problem! Thanks for the tip, I was at a loss as to what was chewing all my CPU.

    It was enough for me to just unset the “Allow other users to view your desktop” setting under System > Preferences > Remote Desktop.

  2. Thanks Tom. Happy to have helped.

  3. thanks :) i also had the same problem. i wasn’t sure what to kill since top was only showing xorg taking all of my cpu instead of vino server and i didn’t want to kill xorg >_> lulz.

    hope there will be a fix for this vino-server bug soon >_<

  6. Thanks for the tip. Funny that it took this long to find your tip through all the BS on the launchpad forums. They really need to fix those up so that they’re easier to look at. Anyways. This fixed my problem. Props.
