When I enter my Bios it says I have 1 Gigish and in ubuntu 243.1 MiB. Things might be alot faster with that ram working. I have a dell E210882 Motherboard.

I am looking to buy some memory for my netbook. Currently I have 1 GB of DDR3 memory. However, the specification says that 2 GB of memory is the max. However, when I do the following it says that 4GB is the max:
i have just put in my new 320gb seagate hdd and it shows in bios, however upon booting from USB it does not show on the OS, nor does it show on the installer does anyone have any idea what could cause this or how to sort it?
my computer shows no video not even the bios. my conpound from the heat skin ran? i can send the mother board back look at the pic and if this has any thing to do whith why i have no video.
I come bearing a question that I hope I can get some info on. Here's the situation: I installed Ubuntu 10.04 Netbook Remix on my Acer Aspire One (didn't want it, but got it for free). I installed and am dual booting it with windows 7 basic. Both worked fine until this morning when the laptop ran out of battery and shut down.Now, on start up, the BIOS screen flashes, and its not the same BIOS screen, but I can't tell what it says, its moving too fast, the laptop then restarts. This problem may be bigger than the linux part of it
I have decided to load the OS on a old HP Compaq DX2000 MT to see if its for me before putting it on my main machine.
I loaded Ubuntu version 10.10 last night everything was fine except I could not get my wireless adapter to work, I decided to connect via ethernet to get the latest updates and drivers.
After the updates and restart I now get the non executable memory error. when I enter /usr/bin/check-bios-nx --verbose
I am told I have NX capabilities and should go to the bios and enable it. There is nothing in the bios to enable as far as I can see. So I enter the command
I tried to install OpenSuse 11.3 on my brand new pc, which already had Windows 7 proffessional in it, and I went step by step through the installation without changing anything. It didn't work. I tried for a second time and this error message kept popping up: "Creating device modes with udev 2.0436224] [drm: i915_diver_load]*ERROR*Detected broken BIOS with 262140/2644kb of video memory stolen. 2.0436224] [drm: i915_diver_load]*ERROR*Disabling GEM(try reducing stolen memory or updating the BIOS to fix)"
And then a lot of letters and numbers wich make no sense to me. Now the only way I can initiate OpenSuse is with the OSuse boot dvd and on failsafe mode.
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":
I'm encountering a strange problem. I need to open and forward all UDP and TCP ports related to VoIPtelephony (5000:32000) in the Suse 11.1 server that's acting as router/firewall in our setup. The ports must redirect to a Asterisk server in the local network. (This server has the IP adress 192.168.0.3)I've opened ports in Yast (Firewall>Ports>Advanced) and putted in some masquerading rulesirewall>Masquerading):0/0,192.168.0.3,tcp,5000:31000,5000:310000/0,192.168.0.3,udp,5000:31000,5000:31000when I do a nmap localhost I get:Starting Nmap 4.75 at 2010-01-08 16:52 CETInteresting ports on localhost (127.0.0.1):

I have a computer with 16GB of ram. At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.
I have had a fresh install of Ubuntu 9.10 and installed some software after that.Since third some, some process is eating half of my memory.I have checked processes running in system manager but everything is normal.Maximum is consumed by compiz which is about 26 mb, seems very normal.I did restarted my computer several times, and in the start for 5 mins, its fine after that again my cpu fans runs at very fast speed and my one cpu is used up 95 % (I have dual core).Please help me out, this invisible thing is driving me crazy.I am attaching my htop screen shot (sorted by cpu %), now the cpu is not used by completely but fan is still struggling hard and fast.
I am using malloc and frees a lot in my program. It shows its allocated but when i remove it doesnt show as the memory is removed(I am using the top command to view VIRT memory usage). If this continously grows what would happen to my program (Will it go out of memory?)
I am looking for free database that has low memory usage and innodb and memory like engins that has C API and support trigger and client/server support for using in embedded linux systems.
I am new to C and linux. My code below does arbitary writes but I cant figure out where or how it does it.
I am calling the insertNode() function with seq = 'MISSISSPPI$' and alphabets = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ$'
Code:
Weird behaviour I should mention is that when I check for NULL pointer in node->child[index], the unassigned values are not null anymore, they point to arbitary memory.
we found that if we use 'top' to show the memory usage of a server (SuSe Linux 10), we can get virtual memory usage as well as 'Resident memory' usage. For virtual mem or a particular process, it is around 1.1GB, which is large but for resident memory, it only consumes 300MB. Are there anyone who knows what the differences are? I would also like to know whether the difference (1.1GB - 300MB) = 800MB are actually available for use by other applications in the system.
I am monitoring physical memory in a server I administer, and my hardware provider told me they had increased physical memory size to 4Gb... However, using several tools (free -m; top; dmesg | grep Memory; grep MemTotal /proc/meminfo I discovered that I actually have 3Gb, not 4... But, my doubt comes from the fact that dmesg | grem Memory tells me I have 3103396k/4194304k available The first number is effectively 3Gb, but the second one, is 4! so, why I am looking at this two different numbers?
I am writing an application that wants to access periphals registers outside the standard (allowed) memory area.
Doing so gets me "segmentation fault".
I know, this is natural behaviour.
One way of getting around this is writing the module which has to be loaded by linux. I will consider this some time later.
For now, I want to come to some quick result and allow linux or gcc compiler to write to those memory areas of periphals. Is there a direct way to do so?
Is that possible that SHM shared memory is counted as cache memory on Linux with kernel 2.6.18?If find it really odd since this memory is not file backed, but I have a piece of code that loads data using shm_open+mmap, and it generates an amount of cache memory in /proc/meminfo that corresponds exactly to the amount of shared memory (I load that data from a file but I am using posix_fadvise(fd,0,0,POSIX_FADV_DONTNEED) to ensure this file is not cached and I made sure that it is working as expected). As far as I know SHM memory was not tagged as cache memory with kernel 2.6.9.If it is the case it is really unfortunate since normally cache memory can be considered to be part of the "available" memory since it can be flushed promptly but this is clearly not the case with SHM memory... Is there an easy way to get the total amount of used SHM memory on a system?
This is my first post in these forums. I'm still quite new to Linux (using Mint 9) so please bear with my not-very-articulate question(s)When I boot up and open up a tty terminal I get a message saying "Memory corruption detected in low memory." I've done an extensive google search about the issue and it seems not uncommon. I ran a memtest with no errors returned, so I'm sure that there's nothing really wrong with the memory; apparently it's a bug in the kernel that's causing this.
I found from command 'top' that 8GB memory are used. However, using command 'ps' with some options to grep the running processes and then summing up the memory used by the running processes are less than 2 GB. Where has the used memory gone ?
I have been setting up a vps I got out with bhost.net, with CentOS installed. I've been learning and have set up everying I need with the exception of ftp/sftp.
Using yum I installed vsftpd and ran into problems, thinking it was something I might of done I did a fresh install of CentOS and I still recieve the same problem on a fresh install so it is nothing I have done to the server.
The problem is when connecting via a sftp client I get an out of memory error. This error is listed in the putty faq ( url ) under A.7.5, there is a brief explaintion of the cure under A.7.6.
there is mention of a login script but I don't know where this is located. I'm a novice at Linux but by no means incompotent when it comes to computing.
I have a query regarding top & virtual memory. When we run top it show VIRT (Virtual Mem), RES (Resident Mem) & SHR (Shared Memory). The total virtual memory of my machine is 4 GBs (2 GB RAM + 2 GB Swap), but still I am able to see a process showing 4000m virtual memory column. what it means, as its show VIRT Mem more than actual available VIRT memory
I have just installed ubuntu 10 on a thinkpad t410. At first everything worked swimmingly, INCLUDING the wireless. After about five minutes, the wireless stopped working, in that it seemed to think it was still connected but pinging didn't work. I've now restarted several times, and each time I restart, the wireless works for about 1 minute, then stops working. If I try to disconnect and reconnect it will not reconnect (until I restart, that is).
iwconfig shows the correct ESSID and ifconfig shows an address, and "connection information" shows a varying percentage of connection.
When I start bluej and try to open files from my memory stick the memory stick is not available. Is there any way that I can open files directly in bluej from my memory stick.
I'm trying to do a test run of 10.04 LTS with a cd but the machine isn't booting from the cd ( or two other subsequent cds that I know work). I thought I remembered not having to do anything to make this boot from a cd, so either something has changed or I've flipped out. Once it boots 9.04 from the hard drive it recognizes that there is a program cd in there though. I've tried F8, F10, F12 and ESC - ESC nets me a list of drives to start from Ubuntu 9.04 and several versions of recovery mode also a command line. I'm baffled - this is probably something simple but its beyond me at this point.
