General :: CPU / Fan Overuse ( Npviewer.bin, Java ) Temps Up To 68C?
May 2, 2010
I just installed Ubuntu 10.04 on my Dell Insp. 1545 2.16 GHZ 3GB RAM I have the following problem that I don't have on Vista. Problems:
1. Fan is running almost constantly
2. Cpu temps reaching 69C, stable at 54C
3. Temps spike especially with Java and npviewer.bin (in both FF/CHROME)
Ex. In system monitor, npviewer and Java take up about 90%, and while running, the CPUs are at 1. 80% 2. 90%. However, even when these processes are killed, basic activity (FF, file browsing etc) cpu% stay near 50/70, and fan stays on. Question: any suggestions? I heard restricted drivers could cause this problem. Any thoughts?

since upgrading to 10.04, npviewer.bin has a habit of eating up my cpu (q6600) resources whenever i watch a flash video. this is kinda annoying as i like to play music on videos while browsing the internet

I'm having where processes (firefox and npviewer seem to be major culprits) just lock up taking excessive (i.e. 100% of the CPU) and state' 'uninterruptible' in the system monitor. This carries through to all my other processes (windows) and makes them unresponsive. What's worse, is when the system gets in this state, even the system monitor itself becomes 'gray' and unresponsive. Often 30 seconds later, I can get a 2 second window with which to access my system monitor (it becomes colored again) before going gray again. During that small window, I might be able to kill the offending processes.
Problem is, the system does this literally all the time. Like when I have firefox open with perhaps 4 tabs, that's all it takes to cause everything to begin locking up -- and at times, that might be the only application open that causes this system lock up. Other things that seem to trigger this is if firefox is running and the system update opens up. I am simply finding Ubuntu to just not be reliable enough, and as much as I hate the idea of switching back to windows, if I can't find a solution (that has been plaguing me for months) I don't see any other choice. Sadly, I find very little information on a solution to this problem, but, searching through the forums and on google, I can see that I am not alone.

I have been trying to add more sensors for hdd drives temperatures but i see only one and no place/options to add more.I know they all work,(i have 4 physical hdd) if i use the hhdtemp command (dev/sdXX) it show the temp for all of them (one at time).
Any way to make gkrellm display all of them ?
I,ve been googling around and searching on various forums but haven't found anything about that (other than how to make it work,or troubleshooting to make it work).
I've tried conky ..but gives me more errors than info and i gave up.

When I do the 'sensors' command in Terminal, this is what shows up:
apple@fruit-bowl:~$ sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +52.0C
Core0 Temp: +49.0C
Core1 Temp: +51.0C
Core1 Temp: +48.0C
Both Core0 and Core1's temperatures are shown twice with nearly identical temperatures and it looks like that the temps are switched around. Is there anyway I can fix this?

I'm trying to monitor the temps of /dev/sdb and /dev/sdc in Conky (/dev/sda is an SSD so not necessary, or even possible). I have HDDtemp running as a daemon, and returning correct temps for both drives when run from konsole. Output:
Code:
linux-b98i:/home/hgm # hddtemp /dev/sdb /dev/sdc
/dev/sdb: SAMSUNG HD501LJ: 35°C
[code]....

Does anyone know if it's possible to grab the temperatures from an ATI card using the open source radeon driver (not fglrx/catalyst).
I must say that the radeon driver has come a long way and works wonderfully under Lucid for my needs. I'm just a bit worried about the lack of PM support and how high my temps might be. I would prefer some way to keep an eye on things

I'm using Ubuntu Netbook Edition on my family's 4 netbooks. Sadly (and a big mistake in my opinion?), I can't add a temp monitoring applet to my panel, but that's not really the point. I am needing a way to monitor my computer temps that includes a graph (kinda like a CPU usage monitoring graph).
I really need this ability because I have another regular laptop that overheats at times and I would like to see the history without using a script to do it via text and logging.

I'm thinking of a web based app that will monitor temps and values fed in from a data acquisition device but am seeking advice on what to use to produce the web page would php be powerful enough? The app will also have to have access to a shell for scripting, I know thats a security risk but it will not be in an exposed env. The web page will have a series of lcd readouts displaying the aquired data refresh rates will probably be around 5 seconds along with control buttons to turn on and off values. Storing data in a mysql database for statistical reports would be needed eventually. Ubuntu 9.10 will be the os. Is python easily integrated into apache?

On FC11 64 bit with Adobe flash plugin for Linux installed, I see segfault errors from "npviewer" in /var/log/messages. The only browser I have tried yet, Firefox, has glitches every now and then. Sometimes it shows the title of a page in a tab, but the page is blank. This can even happen when I try the Google main page. Is it true that npviewer has something to do with Adobe flash? Is there a way to fix the problem? If it is caused by Adobe flash, is there a different plugin that will replace Adobe flash player?

I try to install the java plugin but the java test pages show not installed. I have tried the openjdk-6-jdk package and the Oracle/Sun 1.6.0_26 version to no avail.
Is there some good instructions page someplace? I have yet to find a set of instructions that provides something clear that works.

Code: ~ $ /usr/java/jre1.6.0_25/bin/java -showversion Error occurred during initialization of VMjava/lang/NoClassDefFoundError: java/lang/Object
That's the error I get. When trying to run a java app with the firefox plugin, the browser simply crashes if it's the 64bit java or tells me it's not installed if it's the 32bit version.
I'm at a loss as to what to do. I think it has something to do with leftover gunk from a previous version I misinstalled(Is that even a word?) Anyway, the only thing that google could come up with was a solution for windows which laid blame on Bill Gates for having a bunch of pf (java prefetch) files stuffed into c:windows for no apparent reason. The solution was to delete them, but I can't seem to find the java prefetch folder in linux. The method I used is downloading the rpm from java.com the rpm2tgz then installpkg then cp libnpjp2.so to firefox plugins folder.

This is my first post and I'm pretty new on Debian. I had used Ubunu for a while now and I've decided to move on Debian Squeeze.But I've one problem: I've a Java programm to install and the installer is GUI Java based. When I run the script, I've the next message:
Preparing to install. Extracting the JRE from the installer archive.Unpacking the JRE.Extracting the installation resources from the installer archive.Configuring the installer for this system's environment.Launching installer Graphical installers are not supported by the VM. The console mode will be used instead. Preparing CONSOLE Mode Installation. But this program is not able to run the installation in console mode.
I've tried to install sun-java6-jre but without success.Has anyone an idea to help me install this programm? My Configuration: Debian Squeeze 6.0 amd64.

If you are interested, Java SE 6 Update 24 is available. The Check Java Version link in my signature will tell you if you are up to date or not. The Update Java Version link in my signature will tell you how to obtain and install the latest version. The 32 bit version install directions are on the left side of that page and the 64 bit instructions are on the right side.
Just remember to remove the current version before installing the new one as it says in the instructions. The remove instructions are below the install instructions. Also, in Step 9 - "Now you'll want to tell the system, that there's a new Java version available." See the note below it that says if you get an error upon entering the command once, enter it a second time. I have to do that and sometimes forget. Just thought I would mention that. These instructions are already setup for version 6 update 24, but they can be modified for any update and they will work. I have been using these instructions for a couple of years and they work.

I would like to install JRE-6u25 on ubuntu.
When I go on the website I see only RPM and another download called:
linux self extracting. The file name for this one is: JRE-6u25-linux-i586.bin
It says to restart the browser after install.
I want to install java to play minecraft. I'm having some speed issues using openJDK.
Would the self extracting file work for minecraft standalone? (I tried playing in a browser without success).
Is using the self extracting file the same as using say the RPM?
