Ubuntu :: CPU Usage At 100%, Displaying Extra CPU?
Nov 26, 2010
I'm relatively new with Ubuntu- but I'm pretty experienced otherwise with computers. I just installed Ubuntu on my Intel machine and it seemed to be running a little slow so I checked the System Monitor and found that there were 2 CPU's being displayed (I only have 1) and that one or both were maxed out at 100%. What I have for hardware is one Intel Atom 1.6Ghz processor, with 2GB of ram. When I check what resources are running, none of them seem to be taking up that much memory (firefox being the most at 60mb).Any advice on what might be going on here? How is it displaying 2 CPU's when I only have one?

A small "mom and pop" WISP would like to provide account usage information to customers.Basically, when a person connecting to the WISP's web site is a customer with an IP address from within the WISP's subnets, a link would appear on the web page where customers could read total bandwidth usage (daily, weekly, monthly, and yearly totals and averages) and public IP address. Information could include the top five bandwidth URLs visited; graphs or charts of usage; and usage during specific periods, such as business hours (8AM-5PM), evening hours (5PM-10PM), night (10PM-8AM), and weekends (10PM Friday-8AM Monday).
The WISP has installed cricket (http://cricket.sourceforge.net) and rrdtool (http://oss.oetiker.ch/rrdtool). The next trick is to grab and format the data for customers.I'm not looking for answers like "look at xyz package." Helpful responses will include a rudimentary outline to solve the problem. That is, "xyz package" might indeed be what the WISP needs, but some guidance how to use xyz is needed to move down the road.I have no experience with this type of thing. I appreciate responses from people who are experienced.

I have a network connection between 3 computers sharing the same net bandwidth with the same router (modem), I wanted to know how much every one of this network taking from the bandwidth, I want an easy program like switch-sniffer (see the pic) to scan the network and tell me how much every one taking from this network in real time.

there are 2 related to 11.3: openSUSE_11.3/ and openSUSE_11.3_KDE_Distro_Factory/ Index of /repositories/KDE:/Extra they are not listed as official kde4 repos here KDE repositories - openSUSE, but they are in the same directory structure on the build service so it would assume they are official (what ever official means) They have rpm's I didn't see in community and playground (at least for 11.3) such as audex and clementine I would guess that they are for the stable and factory versions of KDE4 but then shouldn't there be a 3rd for unstable if this was the case? Or do they refer to the distro, 11.3 stable and 11.3 factory

I was trying to get the status of memory usage and disk usage using sigar in windows and ubuntu. done this in windows by just copying the sigar library into jdk library. But i was unable to do so in ubuntu. I've copied the library to java-6-sun library but still can't run the program.

I'm running into a problem where my system is running out of disk space on the root partition, but I can't figure out where the runaway usage is. I've had a stable system for a couple of years now, and it just ran out of space. I cleaned some files up to get the system workable again, but can't find the big usage area, and I'm getting conflicting results.For example, when I do a df it says I'm using 44GB out of 58 GB:
Code:
[root@Zion ~]# df -h
Filesystem Size Used Avail Use% Mounted on

I've come across a really strange issue with one of my RHEL servers. The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":
Code:
[root@server1 ~]# free -m
total used free shared buffers cached
Mem: 12011 7946 4065 0 4 23
-/+ buffers/cache: 7919 4092

I followed the following instructions [URL] to get my custom text to appear. The result was many GLTexts in my screensaver properties.
Does anyone know what I need to edit to get rid of all the extra entries?

So i saw a thread somewhere about using a thumb drive to make extra ram for your pc. This was of course on a windows pc. I was wondering if this works on Ubuntu also and if it is really worth it?
Also if you have 4 USB ports could you put in 4 usb thumb drives and have a fantastic amount of ram?

I have a problem while burning a CD-Extra (audio+data in two seperate sessions) in k3b 1.68.0~alpha3-0ub on Karmic. The audio tracks are being burned and the session is closed, but k3b does not start burning the second session. There is the last status message in the log: "Searching previous session" and one near the progress bar: "Closing session". Normally it should close the audio session, eject the burner for resetting his state and begin burning the second session. But in fact it just stops, instead of burning the second session. My only option is to cancel.
I already tried to add -eject into the user options of wodim/cdrecord. It ejects, but it didn't help. The first (audio-)session nevertheless is correctly burned, only the second (data-)session is missing. I tried to switch the writing app to cdrdao (option in k3b), but in this mode k3b dies with a segmentation fault. Only "auto" or "cdrecord" mode works. (In fact "auto" chooses cdrecord). There doesn't seem to be a different version of k3b available in synaptic to try out. I switched over from gentoo, where k3b worked. Unfortunately I cannot remember the exact version of k3b in gentoo. The system was approx. 1 year old.
PS: Is there a native Gnome/GTK app that does CD-Extra? Brasero and GnomeBaker do not support it yet.

When I open a directory from the Places menu on the Gnome panel, two Nautilus windows open up. One is the location I asked for. The other is always "/media/Data/ZZZMaint/PC/R stats pkg". I think it may be to do with the fact that some time earlier I had created a launcher in the Main Menu - called "R documentation"', with command "nautilus --no-desktop '/media/Data/ZZZMaint/PC/R stats pkg' " (the idea was to have a menu item that opened up a folder containing a set of documents I refer to). I have since disabled that menu item but the problem remains. I would very much like to stop Nautilus opening this extra window.I've tried looking through gconf-editor but haven't seen anything that looks relevant. The extra window doesn't get opened when I run Nautilus from other places, but it always happens when Nautilus is opened from the Places Menu, regardless of whether I'm opening a drive or a bookmark.

I've recently installed the package xscreensaver-gl-extra, and noticed not one of the screensavers on that package works - all I get is a blank screen on all of them. However, I remember those screensavers working under Jaunty on exactly the same hardware (didn't test them on Karmic).How can I make them work again?

I have Ubuntu Linux installed on a hard drive in a seperate computer. I want to transfer some stuff so I pulled the drive and hooked it up to my main machine. I then installed Ext2Explore so I could read the drive. I am able to read it now and see all of the folders but it appears that I am only able to see the main partition. With the other partitions, I see them listed in the Media folder but I click on them and they are all empty. Does anybody know how I can retrieve the data in these partitions?

The hardware devices drivers list three different types of drivers onboard including what appears to be the latest one with accelerated graphics capability. When I try to improve the visual effects to 'extra' it keeps telling me there's an error. I've tried improving the effects with all three but still getting the error.

Whenever I try to run any of my OpenGL programs with Settings -> Appearance -> Visual Effects: Extra, the program window flickers and disappears. However, if I turn my effects to Normal, my OpenGL programs run smoothly. Any way to have both on at the same time?
Code:
$ fglrxinfo display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Mobility Radeon HD 5800 Series
OpenGL version string: 1.4 (4.0.10237 Compatibility Profile Context)

I have found that the package "ubuntu-wallpapers-extra" appears to be the culprit in imposing a system-wide new default of a particular wallpaper background image on all users (both those already added and those yet to be added) as well as the login screen. It can be overridden. The problem is, it has to be overridden.
Anyone know of a way I can block any such changes from happening? If not that, what about a tool that will automatically revert such changes. The goal is so that users (and the login context) won't need an explicit background image to be set and when so, will get the image that was the default at install time.

I have 10.10 64-bit on a Fujitsu T900. the hard drive has windows seven as well (64-bit). The win7 is the orginal from the manufacture. the boot log originally had (in this order): Win7, Windows Vista (about 100 MB not sure why but can't remove), recovery partition. I put ubuntu on after those three. Some times when the computer goes into suspend mode from ubuntu it will not wake up after wards. the only option it to power i down manually. when it comes back up there is now a second reference to ubuntu in the boot log. this has happened several times. there are now four valid references to ubuntu in the boot loader. I need to remove three of them, but i'm concerned that removing them will compromise ubuntu. Also I'm not sure where the boo log in windows seven is.

I want to know how to install KDE on Ubuntu and Gnome on Kubuntu.
The commands
apt-get install ubuntu-desktop
apt-get install kubuntu-desktop
are not the solution, because they install all distro packages, and I want only the base of desktops KDE and Gnome.
I can install LXDE with
apt-get install lxde
instead of
apt-get install lubuntu-desktop
I can install Xfce with
apt-get install xfce4
instead of
apt-get install xubuntu-desktop
However, I could not do the same with KDE and Gnome.

My ubuntu server is a 1.5T with 448GB available. When I backup my files each night, my files only amount to 397GB. Is there an easy way to see where the extra 600 GB on my server is located? I think that I might have had a couple of old backups write to the server, but I cannot find them.

I have two hard drives in my compy. One is 500 gb and the other is ~40 gb. I tried to install ubuntu on the 40 gb one because the 500 gb one is starting to die. When I use a live cd to install and partition the harddrive.
It shows I have 3:
/dev/sdb] and /dev/mapper/nvidia_fhidaeja are physically the same drive but appear as two, independent but equal drives.I kinda just ignore it and move on. I install ubuntu and try to boot and I receive an error saying that grub can't be found. I install and repeat two more times and get the same message. I'm thinking the the "extra" drive has something to do with it, but I'm not sure. I've tried reformatting it and resetting bios but nothing seems to work.
