Ubuntu :: Can't Figure Out What Is Using RAM (and It's Not The Cache)?
Jun 15, 2010
I've been troubled by the high amount of RAM that is used by my Ubuntu desktop. Before I installed Ubuntu 10.04 (desktop, 64-bit) my system used around 500MB of RAM when no applications were open (just cold boot into the GNOME under 9.10). But when I installed Lucid, I've noticed that my used memory is now reported as 1GB or more as soon as I log into the system.
I want to figure out what is using all the extra RAM but I can't seems to find the culprit. I looked at all of the processes and numbers just don't add up. I exported the list of processes into a file and summed up the memory used by every process in a spreadsheet. The total came to around 700MB. Yet, both System Monitor and "free" reported the time that system was using over 1GB of memory. This means that at least 300MB of RAM are used but not by any process, at least as reported by "ps".

I don't understand this error nor do I know how to solve the issue that is causing the error. Anyone care to comment?

Error: Caching enabled but no local cache of //var/cache/yum/updates-newkey/filelists.sqlite.bz2 from updates-newkey
I know JohnVV. "Install a supported version of Fedora, like Fedora 11". This is on a box that has all 11 releases of Fedora installed. It's a toy and I like to play around with it.

I was laughing about klackenfus's post with the ancient RH install, and then work has me dig up an old server that has been out of use for some time. It has some proprietary binaries installed that intentionally tries to hide files to prevent copying (and we are no longer paying for support or have install binaries), so a clean install is not preferable.
Basically it has been out of commission for so long, that the apt-get upgrade DL is larger than the /var partition (apt caches to /var/cache/apt/archives).
I can upgrade the bigger packages manually until I get under the threshold, but then I learn nothing new. So I'm curious if I can redirect the cache of apt to a specified folder either on the command line or via a config setting?

i was looking for a way to stop my menus taking a few seconds to load my icons when i first open them and found a few guides suggesting using the gtk-upate-icon-cache command, but with the any colour you like icon theme i'm using (stored in my home folder .icons directory) i kept getting a "gtk-update-icon-cache: The generated cache was invalid." fault i used the inbuilt facility in the acyl script to copy the icons to the usr/share/icons directory and tried the command again, this time using sudo gtk-update-icon-cache --force --ignore-theme-index /usr/share/icons/ACYL_Icon_Theme_0.8.1/ but i still get the same error. i tried with several of the custom icon themes i've installed and only 1 of the first 7 or 8 i tried successfully created the cache.

i think this is not the right place for this post, but i can not figure out how to post a bug. i am talking about the permissions of: /tmp/orbit-root. please don't tell me now "don't" log in as root if you once login as user root from the login screen the permissions of /tmp/orbit-root are set to: drwx root but if log out the permissions are not set back / or the entry will be deleted. this will end for the next login as a normal user that you will get a bulp of error messages. easy to reproduce. this is not a feature - it's a bug.

I made a bootable usb drive that I would like to test on my sony viao laptop. I cannot seem to figure out how to get into the bios so I could set it to boot from the usb. I tried pressing F10 and F12 while booting but these were all guesses as I do not know which key combination is used to go to bios on this machine.

I know this has been asked, but I can't seem to figure out which answer will work for me.I'm not a programmer. I am an experienced computer user, and have been using 10.04 for about 6 months.I rarely use my Vista OS, and have to sit with my computer as it boots up, so I can select Ubuntu during the process.Vista was on the machine when I installed 10.04, but I would really like it (10.04) to boot first.

I'm attempting to put together a 'nice' front-end for a set of image deployment scripts I've written. I'm running in to two different issues that I'm sure are related, but I can't quite figure out what the cause is. I am populating a variable with information from several text files to form my tag, string and default state for a dialog statement...
Code:
for dir in /tmp/apps/* ; do
APPMENU="$APPMENU $(echo $dir | sed 's//tmp/apps///') $(cat $dir/info)"
An example of the contents of /tmp/apps/office/info:
Code:
'Microsoft Office Enterprise' 'on'
The result of echo $APPMENU:
[Code]...
Does anyone have any idea what I should check for? Is there's a specific quoting method I need? In a Bash script I'm pulling quoted text from a file with cat then writing that same string (hopefully quoted!) to a variable. I have a single set of hard quotes (') in my text files presently.

I installed openjdk-6 on my ubuntu 9.10 system along the the documentation package and some other, related packages that looked promising but I cannot figure out how to access and navigate the documentation. (This is veering out of the scope of this forum but I also cannot figure out whether I have SJSXP installed or how to acquire and install it in case I do not.) Would one of you be gracious enough to help me figure this out so that I can get started?

setting up a wireless network, so bear with me. I just bought a Cisco wireless router and the little USB plug ins (which if I may say, are overly expensive). I can not figure out how to install the router. It is a Linksys E1000 Wireless N Router. I tried to load the software via wine. No luck doing that. I also checked out on Linksys's website and they don't give any info on linux or Ubuntu. Does someone out there know something? Or should I just take this one back and purchase something else

I installed slackware 13.1 (64) but I didn't install kde because I am using fluxbox. Now I would like to install k3b. I have gslapt installed but there are no dependencies listed. The k3b website says that kde is a requirement but that can't be true. find the dependencies of the official slackware package. The slackware book does not seem to have that information.

Choppy RMVB etc. video on totem made me go _insane_So i realized mplayer with VDPAU output was rocking and rolling!But Ubuntu uses TOTEM. So I tried to figure out why TOTEM and VLC couldn't do VDPAU.Lots of users tried with no success, months ago, as I was looking at some threads.Just passing by to inform that I was able to make NVidia's VDPAU technology work with GStreamer by compiling the latest gst-VAAPI lib (~gbeauchesne), like that:
Example RMVB file output $ gst-launch-0.10 -vv filesrc location="~/putz.rmvb" ! ffdemux_rm ! ffdec_rv40 ! x264enc ! vaapidecode ! vaapisink
and no more freezes or choppy video! Graphics card is NVidia 8500 GT, NVIDIA Driver Version: 260.19.06 with Intel Core i7 + 4GB RAM now I'm getting the 0.11 gst GIT and will see if it makes any difference.[URL]...

I know you've probably seen this type of request numerous times, but I just can't get it right.Objective: to get to grips with Linux network routers.Problem: Cannot ping across the router.On the router itself, I can ping to clients on ether side.Server: Ubuntu 10.10NIC1: connects to home broadband router. Static IP address. Eth1 has no problem pinging outside world.NIC2: Static IP address. This NIC is configured for DHCP server and will have a home machine or two connected to it assigned IP addresses from the DHCP server.Set ip forwarding from 0 to 1

I am trying to figure out ho to setup EC2 clustering. I am seeing heartbeat as an option. I need something that will monitor the state of a daemon, and not if a daemon is running. For example, say I want httpd to be high availability. Does heartbeat monitor if httpd is not in a hung state, or does it simply do a ps -e |grep httpd? So my question is, how does heartbeat work?
