Ubuntu :: 10.10 (64bit) System Temp Exceeding Acceptable Limits
Apr 9, 2011
I recently installed Ubuntu 10.10 (64bit) on my laptop (Toshiba satellite L300 64bit) and have since had horrible issues with the machine overheating. When the system is idle, the temp is decent, a bit warm maybe. If I start browsing the Internet, temp goes way up. I cant watch more than 1 and a half minutes of a ..... video without the system's temp exceeding acceptable limits, and shutting itself down. I have tried both the 32 bit and 64bit versions of ubuntu 10.10, as well as a 64bit version of 10.4. same overheating issues with all of these.
I am 99.999999 percent sure that it is an issue with my laptop's cooling fan, as although it appears to be spinning, it is so quiet that I would think it was off completely if I were to not tilt the laptop back and check to see if it is spinning. Also, the speed of the fan does not change, regardless of the machines temp. Even before it shuts off because of extremely high temps, the fan is still running at that same speed. I am currently downloading fedora 14, a different linux distro, to see if there is any difference.

When I play a flash video in x86_64 with the latest 64bit flashplayer I will often get a grey rectangle after a few secs rather than playback. This is 100% reproducible if I restart firefox after playing a flash video and try to replay it.If I start firefox from a terminal I can see "invoke_NPP_Destroy: assertion failed:" type errors. Logging off and logging back on fixes, so I investigated which process needs to be restarted. Turns out to be gvfsd, so if you get a grey box do this in a terminal (as a normal user NOT as root)
Code:
killall gvfsd
/usr/libexec/gvfsd &
then refresh the page and all should be fine. (In fact the problem does not recur for an entire session until I login again) If others could report whether this fixes the same problem I can submit a bug report.
EDIT: I am using libflashplayer-10.0.32.18.linux-x86_64.so from here

I would like to limit any process from using more than 500 MB of RAM. AFAIK this is done using RSS in /etc/security/limits.conf but the process called gnome-panel apparently is using 618436 kB of VmRSS. How can this be ?
/etc/security/limits.conf
* hard rss 512000

I have a web server whos DocumentRoot is:/tmp/wwwNow, /temp/www/fake/ is a directory that contains a series of other files/folders.What I want to do is access the files in /temp/www/fake as if they were in the root directory (/temp/www/)For example:
could either be located in "/temp/www/test.php"
-or-
located in "/temp/www/fake/test.php"
so "http://127.0.0.1/test.php" would essentially call both directories. Is this possible? Whould I do this through apache or through the actual file system somehow? (Like some sort of symbolic link?) I would love to hear your input.

Our Apache server is pretty much configured straight out of the box, and I've noticed it is using far more CPU and less memory than another server where I have the following:
RLimitCPU 8
RLimitMEM 100000000
RLimitNPROC 24
The Apache documentation says that if these aren't set, the values are obtain from the OS. How can you tell what those are? I'd like to see if I can tune Apache's performance, but I don't even know if these values are higher or lower than what it's currently using...

I misread this question and thought it was asking something I've needed for a long time. My question is slightly different: how to find directories whose contents exceed a certain size. Is there any *nix way to do this?

I have the simple fortran codes as:
Code:
integer :: i1=2455121, i2=2455121
real :: s1=0.19123840, s2=0.20749992
real*8 :: a1, a2
a1=i1+s1; a2=i2+s2
[Code]....
When s1 and s2 are stated with 'real*8', the 64bit and 32bit systems get the same results.

I have an NTFS file system nfs-automounted on our RedHat servers. Users can read and write to the file system no problem, and can create new files, edit them, and delete them to their heart's content. The only issue is that utilities such as "dos2unix" cannot create temporary working files:
$ dos2unix events.0818.dat
dos2unix: converting file events.0818.dat to UNIX format ...
Failed to open output temp file: Operation not permitted
dos2unix: problems converting file events.0818.dat
This isn't limited to "dos2unix"; any other utility that creates a temporary working file gets the same problem. If I copy the file to a local file system like /tmp, it works fine. Here's the kicker: this works fine on Solaris systems. I can take the "dos2unix" utility over to a Solaris system that has that exact same NTFS file system automounted via NFS, and it works. No issues creating temporary working files at all.

What would be the advantage of running a 64bit system over a 32bit system? I only have 3GB of ram but plan on kickin another 1GIG into it. But i wanna try 64bit Linux(probably slackware) on it. But first im just wondering what the advantages are people have seen who have used both 32/64bit linux. Speed? Smoothness? And also what are major disadvantages such as compatibility, configuration, etc.

I've decided to build a new system. I been doing a lot of compatibility searches with little luck. I don't have a bunch of money to put into it but here is what I've been looking at. I have been very happy with Ubuntu 10.04 lts Lucid 32-bit version and thought I would install the 64-bit version on this. I would like your input on this system.

The lpr man page says a destination printer can be specified with the -P flag -P destination[/instance] Prints files to the named printer I have 'added' various printers on local Samba shares using the GUI in Ubuntu/Gnome. How can I get a list of these available printers in the format that the -P flag expects (preferably from a bash shell)?

I just installed it yesterday, version 10.10, desktop edition, downloaded from Ubuntu's site; running it along side Windows; and love it from the get go, but... I can't get the Flash plugin to work.
I'm running a Toshiba Satellite Pro P505-S8945 with this specs:
2.0GHz Intel Core2 Duo P7350 Processor
400GB Hard Drive, DVD SuperMulti Drive
Microsoft Windows 7 Home Premium (32bit), 4GB RAM
ATI Radeon HD 4570 Graphics
I tried installing the 32bit version on Flash but kept getting error messages about "wrong architecture i386", so, I went to the (sorry if i make a mistake I'm paraphrasing) "Ubuntu software center", the application within Ubuntu where you can go to the repositories and get software upgrades, and I realized that for some reason Ubuntu is recognizing my system as running on an AMD 64 processor, which I'm not! Mind you, I haven't tried to install the 64bit version of flash, just wondering really, the reason why Ubuntu would say that I'm running on a 64bit AMD processor!

I'm getting random system hangs and display issues when using my computer with my nVidia graphics card. On a lark, i checked /proc/interrupts and noticed that the nvidia device is sharing an interrupt with one of my USB boards, as well as my integrated sound card. i managed to move my sound card by editing my alsa-base and adding:
Code: options snd-hda-intel enable_msi=1 This helps mostly, but i'm still getting intermittant issues. is there any way to shift the interrupt of my gfx card (or usb controller) to avoid this potential conflict? i know the devices should be able to co-exist, but i've seen several people having issues when an nVidia card shares interrupts.

I'm having problems upgrading my FF browser from the standard 3.5 up to 3.6. This is a 64bit system, & if I can provide any other info about it, just ask.I've searched this forum for the help I'm looking for, but I have not yet seen an acceptable answer. If this has glitches, or is too complicated, I won't even bother....3.5 is fine for now, but it would be nice to upgrade.

I've got a problem with installing 64bit systems on Virtual Box. It is reporting that my 64 bit virtualization abilities (something like v-AMD or so) are present but not enabled. There is also an advice to enable it in the bios but I can't find anything like this actually. My motherboard is Asus M4A88TD-M EVO with quad-core AMD processor. IS there any trick to enable this feature somewhere in the system or it is a limitation of my hardware?

My printer wont work on 64bit ubuntu, no drivers. Just for 32bit so I don't know all the technical stuff to get it to work if there was a way to, but anyways. I tried to run ubuntu 32bit and I have a lot of boot problems. Sometimes it will boot but most of the time it wont. I have to hard reboot every time 6 or 7 times just to get it to boot. I was wondering what could be the problem. For some reason I was thinking maybe it was my hard drive being to large (1.5 terabyte) its been a while since I've tried but I don't remember there being any error messages just a black screen. I've waited up to around 5 hours for one boot so I know I am giving it enough time. Is there a fix to make 32bit ubuntu use a large hard drive like that. I know there is one for the ram but I love ubuntu and would like to have a stable system and use my printer at the same time.

I am thinking about upgrading to 64bit Ubuntu 10.10 because I have heard it's good for gaming and makes things run smoother. Also, I know it's the new thing and I'm going to have to switch eventually. Point is I don't want to loose my data with the clean install and I was wondering if I backup my current system, which is 32bit (assuming there is a backup utility, I thought I saw one) will I be able to load that on my new 64bit install?

I'm trying to set up a share for my system which is dual booting windows 7 64bit and ubuntu 32bit 10.10 What i did
-Install Samba from the Ubuntu software center
- In System->Admin->Samba add the share for my /Home/Downloads
- In smb.conf i edited the workgroup to that of my windows7 workgroup
- In the home folder right clicked on Downloads and in sharing option i allowed others create and delete
privileges and Guest access ( security not an issue). Then allowed Nautilus to add the permissions automatically. Now from what I have seen if i go into windows 7 in the network section i should have a Ubuntu share appearing but i don't. The only devices which show are the router and the computer itself ( of which ubuntu isn't in) Is there anything i missed or how do i access these files ?

Just noticed that my kids are no longer able to play webkinz on my 64bit system (Edubuntu). Webkinz also doesn't work on my 64bit Xubuntu system. Looks like 64bit Flash is broken? -- or something is broken between Webkinz and the latest flash. Webkinz, predictably enough, works on Windows, but also works on my 32bit Linux system with the latest flash.Just wondering if any of you out there with a 64bit system could try accessing Webkinz (if you can see the Login moniker and click it, then it's working on your system).

Today I noticed, that despite a 1kb/s limit upload being set i was seeding at an unlimited bandwidth, it had been running for 3 hours wasting about 300mb.
I had never seen this before, however 10gb mysteriously disappeared from my 25 quota last month as i dont mind seeding things at 1kb to help people get the missing bits. My 25gb costs me $100 with the larger package being $160 so i dont have much choice but to be stingy.

i realised that although before when i had windows7 my relative download speed was around 5.0 MB/s ( i have a 50MB virgin connection)now with ubuntu 10.10 im limited to only 2.8MB/s or somewhere around there.
First i tested my wireless speed on another laptop (with windows 7) on the same network and the speed was as i said around 5.0MB/s sometimes even more. So i thought it was only chrome that i was using at that point.However, this download speed limitation appears in jdownloader as well as in firefox and i guess the whole system.
SO im wondering if there is any way to set up the speed limit on the system and if there is, how should do i go ahead with this change,through the terminal or through preferences?
