I have an old laptop - samsung q25, it has only 256 mb of RAM and i want to install ubuntu 10.10 on it. System requirements says ubuntu needs minimum 256 mb, so looks like i fit in. But installation and even preview doesn't work.. Ubuntu starts, i can see the wallpaper, a cursor, but there's no panels or installation menus..Is it possible to install ubuntu in console mode?
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 have tried to install F13 on an 8 GB USB memory stick (flash drive, thumb drive) but have had limited success. I used the Live USB Creator method as suggested in the Fedora web site and although I ended up with a bootable USB memory stick, I was unable to save any changes even though I allowed a 2GB persistent overlay.
I then tried to do it using Unetbootin and again got a bootable memory stick but again was unable to save any changes. Could someone explain what I might be doing wrong or is it just not possible to make a bootable memory stick with F12 that will save any changes?
I've been running my Dell Mini 9 with the latest alpha for 10.04 since January, but over the weekend I botched things pretty badly and decided to go back to 9.10.I saved my home directory to another machine, and proceeded to install from a 9.10 USB disk. Things didn't go terribly well (I kept seeing "devkit-disks-daemon" crashing) but the install did complete. I shutdown the netbook, yanked the USB drive and powered it back on only to be greeted the grub menu. Choosing any option yields: Code:error: out of memoryPress any key to continue...I did a little searching in places like:HTML there is no mention of that problem there, and running though the command line instructions has the same results. (the linux command seems to be the problem)I've tried re-installed grub from the directions on the page but it is failing with:
Code: cp: cannot stat '/mnt/boot/grub/ufs1.mod': Input/output error When I look up that file I see:
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 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 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.
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?
My new pc doesn't have a cd rom so I have to use a memory stick, usb hard driver or a SD card. So how do I install ubuntu? For some sh'itty reason I got windows vista installed here which is more frustrating then everything else I have tried.
I met a weird problem when I try to install the new memory to my Dell T7400. The computer is installed ubuntu 9.10, 64 bit version and 8 G memory. I got extra 8 G memories, and installed them on the machine. But the problem is ubuntu does't recognize the new memories, but the BIOS does. I switched the position of the new memories with some old memories, but it turns out the old memories also can not be recognized by the system. I got some memory information by using cat /proc/meminfo
I have an HP dx5150 with Ubuntu 11.04. I recently added 2 new memory chips (total 4) with the same specifications as the originals. The memory is recognized by the BIOS and Memtest returns no errors. The computer boots normally and functions normally for an hour or so, and then freezes. When it freezes it does not accept any input and the screen gets displays a bunch of small green or purple lines. Here is the output from lshw:
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?
I have a old PC i want to make a web server. So i install fedora 15 with minimal install options and now im in text mode, the computer has 128 + 64 = 192 Mb of ram. Is there a low Memory GUI that cant install via Yum ?
Today I installed Lenny on a new server. The server didn't have any CD-Rom, so I tried putting the net install on a memory stick using unetbootin. The install went fine, but the problem was that the memory stick became sda and two SATA disks in the server became sdb and sdc.When I then tried to remove the stick, the SATA disks became sda and sdb, and it would not boot, because it had written the MBR on the stick.It hurried a little bit, so I had to take out a CD player from another computer, and connect it inside the server to get Lenny installed.But it would be cool if it was possible to install with the stick. And no more waste of CD-Rom players that will be used only once.
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 just upgraded to 10.04 and everything was working perfectly, until I upgraded my memory. I cannot boot from live USB / CD - these take me to the initial boot option menu, from which every option (except memory test) results in blinking cursor top left of screen, and cannot type.
Reinstalling my old memory sticks results in the system working fine. The new memory sticks pass memory tests (bios & ubuntu boot) with no errors whatsoever, and the boot sequence progresses fine until the point where the OS tries to boot. I am running AMD Athlon 64 3200+, Asus K8V Deluxe m/b. Memory that works is 2x 512mb PC3200 XMS. Memory that doesn't work is 3x 1gb PC2700 ECC. but please provide instructions on the basis that I know nothing, because I no practically very little about linux / ubuntu.
Today, I burned a copy of Lubuntu 10.10 Maverick Meerkat and tried installing it on my old 2.4Ghz Celeron 192MB RAM (actually 256MB with 64MB dedicated by the BIOS for the internal video card) laptop, which installed Lubuntu 10.04 Lucid Lynx with absolutely no problems. However, when I tried inserting the disk for Maverick this time around, the live CD boot always hangs during Plymouth, and pressing Esc shows:
Code: Generating locales. en_US.UTF-8.I modified the boot options and removed splash and quiet, and I got a whole lot of messages that seemed like errors, but I think the root of the problem was this:
Code: Out of memory: kill process 620 (localedef) source 929 or a child Killed process 620 (localedef) VS2: 59500kB, anon-rss: 57596kB, file-rss: 820kB After that, it got a few messages about localedef timing out for 120 seconds or something. Now I'm no idiot, I'm well aware that my laptop is cutting it very close to the minimum RAM requirements of the live CD, but it's just the live CD that stops me from running Lubuntu, because once it's installed, I have no problems. I ran Lubuntu 10.04's Live CD with no problems and the installed LXDE system ran amazingly fast. I'm sure if I could just install Lubuntu 10.10, it would run at the same speed. The problem is that the Lubuntu wiki still writes the minimum system requirements of:
I have a clean install of 11.04 64bit on a Asus EEE 1201N netbook with 8gb of BIOS seen memory.

Did some more research and find that PAE Kernel is available in 32 bit for Natty but not 64bit. Source Link Here Is there anything that I can do or should I just go back to 32 bit?
I did a standard install of Ubuntu 9.10, then upgraded to 10.04 LTS. Whenever I run htop I get:CPU [~3.8%] Mem [100/244MB] Swp [87/713MB]And free -mMem- total:244 used:214 free:29Swap- total:713 used:86 free:626It seems like I should be using allocating more memory to swap. I should be using more swap, or if this looks normal B. If so, how do I re allocate more memory to swap?I am new to linux and still trying to figure out a lot of things.
