Major problem with Oneiric 11.10 freezing
Tom Bell
etc., it will delay anywhere from 2 to 5 minutes and even then there is
no guarantee that it will actually start. I have 3 screen captures that
illustrate the problem and I will upload them to anyone who is interested.
Below is as much information as I could think to send. If anyone wants
more information, please be specific.
Thank you!

When you ask a question like this and have some screenshots to
illustrate your problem, just like you have now, then post them to:
and simply include the URL(s) pointing to the screenshots. This way you
only upload them once and everybody has access them to see what you are
talking about.

It could be a failing harddisk. Have a look at "/var/log/syslog" if
there is any hint. Or it could be a network share which is not
reachable, but I think that in this case the application should finally
start. Again, there should be a hint in "/var/log/syslog".

One thing to note: these screenshots are completely unretouched, no Photoshop!
You will note the max out of both the CPUs while "top" shows little simultaneous usage of the CPUs.
You will also notice that the network is not in use and that the memory, 8G, is little used.
Any suggestions as to what could be going on would be appreciated!!!
Thank you!

No, I don't see anything either - it seems like I guessed wrong ...
On the screenshots you mentioned in the other mail, it looks quite
strange: While both CPUs are at 100% at the CPU history display, there
is no process of high CPU usage at the output of the "top" command. But
I have no idea what that means.

You seem to have quite a number of processes set to NI of (-)20. Why?
(Unless I have misunderstood something I read, a (-) setting gives a
higher priority to a process than a positive value - even if the process
is idle - but, as I said, I may be wrong.)

I see 'md' in that process list. Are you using LVM with snapshots?

your guess is somewhat correct, but i'm not sure how to verify it. it
doesn't have to be a failing hard drive, but it DOES indicate a huge
interrupts spike, that is usually caused by I/O problems, which almost
always are the result of a hard drive issue.
on my work computer here, i have a very slow PATA hard drive, add the
fact that i'm using full disk encryption, IO becomes a huge bottleneck,
with very similar symptoms as with OP, yet, not that bad. CPU at 100% in
system monitor, but not in top or htop, hard drive crackling maddly
inside the case, as firefox is going through few dozen megabytes of
profile data. it takes firefox some 30 seconds to show any window, then
another 20 seconds to become responsive and usable.
but now to find why is the OP having this....
are you using encryption? if yes, where? root partition? home partition?
full disk? dm-crypt? ecryptfs?
what is your hard drive? size, make, model?
close firefox, open a terminal, make sure you have the package "procps"
installed, if not install it. then, in a terminal, type this:
vmstat -S M 2
once you see one or 2 lines of output, keep it running and start
firefox. keep vmstat running until firefox is up and running, then kill
vmstat with CTRL-C, and copy all its output for us... it'll be helpful
to check the bottlenecks.

install which reused
my, at the time current, setup without change.
That got me the same results so I eventually did a complete reinstall
and the (-) settings are what
resulted from that. The last reinstall reformatted the drive.

Linux Volume Manager. Often used on top of an md device. If you don't know
what it is, you will probably not use it. It can't be installed with the
default Kubuntu installer. You need the alternate CD.
High load when LVM snapshots are present is a known problem.
Unexplained load is often due to I/O problems. Try 'iotop' to see what's
causing I/O.

I tried iotop and it showed "jdb2/sda1-8" as topping out the cpu cycles.
Checking on the internet eventually lead me to anacron.
Now I am checking further to see what value that is and why it is working.
I did not start it or anything like it.
Supposedly it can be scheduled to run daily, not hourly, minutely or
secondly(sic).
I found where it is connected somehow to firefox in the Window Title
part of System Monitor.
/etc/cron.d/anacron:
# /etc/cron.d/anacron: crontab entries for the anacron package
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
#30 7 * * * root test -x /etc/init.d/anacron &&
/usr/sbin/invoke-rc.d anacron start >/dev/null
30 7 * * * root start -q anacron || :
At www.geekstuff.com it says:
/* Begin quote */
Anacron is the cron for desktops and laptops.
Anacron does not expect the system to be running 24 x 7 like a server.
When you want a background job to be executed automatically on a machine
that is not running 24 x 7, you should use anacron.
For example, if you have a backup script scheduled everyday at 11 PM as
a regular cron job, and if your laptop is not up at 11 PM, your backup
job will not be executed.
However, if you have the same job scheduled in anacron, you can be sure
that it will be executed once the laptop come back up.
/* End of quote */
I run my desktop computer 24/7.
I am considering removing anacron, so, has anyone a good argument why not?

I doubt it would make any difference, but a good idea in general. ext4 is more

ext4 is more solid than ext3. Stay with ext4 - it's not your problem.
I go back t what I said before: what are those processes which have a
(-)20 NI?
Each one has a PID so you can go and see what exactly that process is
all about.
In a console/terminal, as root (ie sudo ......) type 'ps aux' which will
list all your running processes owned by everyone on the system.
Get the PID from the lists you produced which are on picpaste then find
them on this list of ps aux and see what they are.

Oops - I thought you meant from ext3 to ext4.
Yeah no, stick with ext4.

Ummm, a slight correction here :-) .
You will need to regenerate the list(s) on picpaste to see the latest
PID numbers for your currently running system - then use ps aux and see

I did try iotop and did not see a whole lot, but, after looking at the
options for iotop,
I tried "iotop -oa" and got a different picture. See pictures below.

These photos show firefox and jdb2/sda1-8 hogging the cpus big time.
It is not just firefox, although firefox was in this particular example.
Just about all the programs I have run have suffered the same problem.
And it is quite often intermittent.
Thank you!

Something totally not right here.....
To begin, how can you have 2 copies of Firefox running by "tommy"?
From my experience, Firefox will not run for a user if it is already
running for that user - in this case "tommy".
A question: if you had already mentioned it I have forgotten already :-(
but which version of Kubuntu are you running, which version of KDE, and
which version of Firefox?
And what is that PID, called jdb2/sda1-8, which is taking up most of the
cpu? It is owned by root. So what is root doing with this jdb2-thingie?

According to Wikipedia, jdb2 is a "generic block device journaling
layer". I suspect it's pretty normal to see a lot of 'jdb2' if there is
a lot of disk I/O. High disk I/O explains speed issues pretty well. It's
also why I asked about LVM with snapshots (and why I switched to FreeBSD
with ZFS when I need snapshots.)
Tom, can you post the output of 'mount'?

See Alvin's following response. I already looked it up myself and it
seems to be something to do
with JFS (Journaling File System), in this case ext4, which you will see
in the equipment list above.
It has me pretty well stumped.
The fact that multiple FIREFOXes ran is also confusing, but shows when
using the 'iotop -oa' command.
I had to run iotop with sudo, just to let you know.
Please keep in mind that this problem is not just with FIREFOX, but just
about every program
that I attempt to run and it happens at different times.
Sometimes I can start a program right away, but have slow downs later on.
Sometimes I click on the program and it never starts
Sometimes I can click on a program, then click on the konsole to open
and the konsole
opens before the program, but it may take awhile to start, or, it could
start right away.
Meanwhile the first program may or may not even show up and sometimes
not for 5-10 minutes.
This problem is v-e-r-y frustrating!!!!!!
Thank you!

normal. The only thing I can figure is that the electronics of the SATA
IDE drive went West(went bad).
The SATA buss is only a buss so I figured that either it was my M/B or
the IDE part of the drive that was defective, so replacing the drive
settled the matter.
Thanks for all your help! Keep this in mind when someone else has a
similar problem!

have? Seems logical
that the numbers are stored somewhere in a file. Would the 10.04-3
numbers be somewhere
in a file?
Is it possible to downgrade to another earlier version of KDE? If so,
Where could I find
instructions for how to do it?

Hi Bruce,
Kubuntu comes out twice a year and what you have is the April 2010 version. It is the most recent long term support version; the next one is 12.04, coming out in April 2012. The "-3" part means it incorporates some security and bug fixes, but I'm not sure what the date code for that is. Each version also has an animal name, but I find them hard to keep track of! The past (April 2011) was Natty Narwhal, current one (October 2011) is Oneiric Ocelot, with Precise Pangolin coming in April 2012.
It would not be a good idea to go to an earlier version (less secure, more bugs), but if you get your hands on a disk from a prior one you can certainly install it. You'll almost certainly lose all your work and have to start over with a clean slate.
If you want to know your version type "cat /etc/issue" or "uname -a" at a command prompt (terminal).

If you mean the Kubuntu version, it is in the file "/etc/issue". If you
regularly run updates, it should now be version 10.04.4. OTOH, if you
actually mean the KDE version, there is an option in the help menu of
all KDE applications.

No, not really. You could only install a previous Kubuntu version.
However those versions prior to 10.04 are no longer supported.

open up a KDE application, go to Help on the toolbar, then "About KDE".
This should give you the correct KDE version towards the top-left of the
window.

It's not recommended to downgrade KDE. If you doesn't like KDE4 look&feel, you may try some of the KDE themes, Gnome, or even Unity.
I recommend you to do exactly the opposite: instead of downgrading, upgrade it. Open up Software Properties and enable "Security" and "Update" Repositories. Doing so, you'll get both security and bug fixes past 10.04-3. If you're brave of heart :D, you can enable also Backports Repository, and get several new packages not included with Kubuntu Lucid, but made available to Natty and/or Oneiric, the following versions.
But if you really have the guts :D :D, install Kubuntu PPA: https://launchpad.net/~kubuntu-ppa/+archive/backports
These will give you the new versions of KDE. I use them on most of my Kubuntu machines.
Answering one of your questions: which version ships with Kubuntu 10.04 Lucid Lynx? Lucid ships with KDE 4.2. You can check it with "apt-cache policy kdebase-runtime". You can also open any KDE app (e.g. konsole), and go Help >> About KDE.
