Upgrade to Ubuntu Gutsy - emvs and udevd 100% cpu usage - aka udevd going nuts
Submitted by David Goodwin on Sat, 20/10/2007 - 07:40.
Yesterday, I upgraded Kat's laptop (Thinkpad R50e) to Ubuntu Gutsy. The upgrade itself seemed to go quite well, aside from one annoying thing with udevd.... namely :
- Load stuck at around 1.0+
- CDROM kept checking if it had a disk in it (constant clicking noise)
- The laptop was whirring away as it tried to cool it's busy self down
- Swap partition no longer works
Further investigation showed that 'udevd' was goggling up the cpu time, and looking in /var/log showed it was also busy writing to a log file.
I then remembered this lwn.net page and the note about evms/udevd not getting along very well in Gusty.
So ...
- apt-get remove evms
- /etc/init.d/udevd stop
- /etc/init.d/udevd start
- 1 Problem fixed :)
Interestingly, I gave Compiz a go on the laptop, but must be too stupid to figure out how to get the spinning cube to work... but some of the other less 'wow' effects did (e.g. ctrl+alt+left/right). So, no wobbly windows for us, it seems.

Compiz
From what I can tell, they've decided to not go with the spinning cube in Gutsy. The 'visual effects' tab selects a pre-defined set of Compiz features, although you should get wobbly windows. I don't know if they've included compiz manager by default, but you should be able to play around with further FX (including the cube) I believe.
cube
must have 4 work spaces 4 the cube to wrk
Some of the plugins for
Some of the plugins for Compiz aren't enabled by default, including the cube desktop and (I think) the wobbly windows.
sudo aptitude install compizconfig-settings-managerwill put a a nice "Advanced Desktop Effects Settings" Options in System - Preferences, where you can turn on the Rotating Cube and Wobby Windows plugins.

Cool; thanks.
Worked for both xubuntu
Worked for both xubuntu installs I use!!
Thx!!
kubuntu / edubuntu etc.
That's not a particular surprise; I'd suspect the same problem hits kubuntu, ubuntu, gubuntu and edubuntu as well... and any other derivatives as well.
Thanks!
Thanks for posting this!
I have experienced some different results w/ my Gutsy Gibbon ...
After
sudo apt-get remove evms
I tried:
/etc/init.d/udevd stop
bash: /etc/init.d/udevd: No such file or directory
So I have for now just:
sudo kill -9 *processname of udevd*
The only location of file udevd on my system now is: /sbin/udevd
So we'll see!
Whew - Upgrade has been a bloody process!
Thanks again..

udevd .... can I spell?
Hi,
There should definately be an init script for udev[d].
Perhaps it was /etc/init.d/udev instead?
(It should go without saying that if you don't restart udevd, removable storage things won't work etc).
The upgrade went quite well for me - it just took some time. At least I didn't have to jump through apt-get hoops with packages being held back etc.
Thanks!
Thanks a ton! This was the first place I stopped to figure out why udevd was taking 100% of the CPU and it's fixed that quickly!
Cube
U must have 4 workspaces if u want the cube to work.. it is a must
Didn't work for me!
When I tried the command /etc/init.d/udevd stop I got this message:
another udev daemon already running
What should I do??
Best Regards,

*shrug*
Destroy the horrible computer?
It sounds like you typed in 'start' for it to moan that another is already running.
