Ubuntu :: Does Operating System Decrease The Original Size Of The HDD
Feb 9, 2011
I have two questions:
1- Does Linux operating system decrease the original size of the HDD? because first I was only using a Windows 7 Ultimate on my Laptop Lenovo G550 4446 the D:/ partition size was 140 GB Free of 190 GB.. After I installed the Linux ubuntu along with the other Windows 7 I found the D:/ partition size became 68 GB free of 122 GB... Why the hell the size decreased?? Did the HDD destroy?
2- How can I hack Wireless Network of type WPA2/WPA or WEP using the linux? I have heard that I can do that using Shell Konsole, but I can't see Shell Konsole in my Linux ubuntu 10.10... Is it required to be installed over the internet or something, or if it is already installed within the operating system, can you tell me where I can find it?
Currently, I have on internal HDD 160GB in size. 20GB are for windows XP partition and the rest is assigned for ubuntu partition(s?). i want to make it now more equal in size, but how can i do that? I'm using ubuntu 11.04...
I recently installed opensuse on my computer due to it contracting a virus and not letting me reistall the original operating system on it. but i know nothing about this program. i have almost everything up to date and working on it. one thing i find strange is when i try to update the flash or java on it that i have to do all this extra stuff to get it to run. i do not know what programs to pull up to type the stuff down thats given in the java installation instructions. the movement of the webpages when scrolling is running slow and videos on ..... do not have as good of quality to it as it did on windows. so im assuming something is out of date or there are settings i need to adjust.
I am new to Fedora, and I noticed when I opened my home folder that I only had 54GB. My HD is 120, and when I used the disk utility, I noticed that 64GB are in ext4! What?! This was not a problem in Ubuntu, so why has it happened now? Is there anyway I can decrease the size of ext4 and give some of it to Fedora?
On F12 and sure need to upgrade. Way back when I first had a bad disk on the "system" disk that was 80G, I only had a 200G lying around. Next time that happened my other 200G wasn't "big" enough it said, so I put a 500G in there. Now it seems I got more bad blocks etc but I need to lower the size 'cos I don't want to put a 1Tb HDD in there. My question from all of this is, how do I decrease the image so I can put it all on a smaller HDD?
Used space on the system disk's partitions is about 30G, so an 80G disk should be sufficient. What I can think of is that I need to "move" all data to the "beginning" of the HDD, then make an image of it but and the entire disk, just the data. I've tried that with no luck since the image seem to get as big as the HDD, hence why I always needed to increase the HDD all the time.
Desperate to reduce RAM usage of my tiny VPS running Ubuntu 9.04 and Apache2.2.11, here I saw that: On Linux, each child process will use 8MB of memory by default. This is probably unnecessary. You can decrease the overall memory used by Apache by setting ThreadStackSize used by Apache by setting ThreadStackSize to 1MB in.
So I tried to give the suggestion a try. But when I append: ThreadStackSize 1000000 in my /etc/apache2/httpd.conf <IfModule mpm_prefork_module> directive, and restarted apache, it failed with this message: Invalid command 'ThreadStackSize', perhaps misspelled or defined by a module not included in the server configuration
So I figured out that the relevant modules are neither enabled nor available on apache2. Now I am wondering whether there is a way to decrease the ThreadStackSize without the need to compile apache from source? If not, what should I do?
How can I decrease the amount of video memory in a debian squeeze laptop? The amount of video memory is 1GB and I want to reduce it to 512MB or 256MB. How can I do this
What I mean is I'd like to watch stuff in its original size but with the rest of the screen black, the way it is in full screen view (but I don't want it zoomed). RealPlayer calls this option "theatre view". Is there a line I can put into terminal? I tried
Code:
sudo gedit /etc/mplayer/mplayer.conf
and changing commenting in zoom=yes and changing it to zoom=no. Made no difference.
When booting into my slack12 fluxbox desktop today my fonts were so small they were hard to read. The same is true if I use kde. I didn't change anything that I can think of. I tried running fc-cache but it didn't change anything. My xorg.conf hasnt changed. Interestingly, my xterm font didn't change size, but the konsole font is tiny like my other desktop fonts.
We have recently built some RAC (OS:RHEL55) servers and after the Oracle guys have installed their application, somehow the directory / is using the maximum space. I contacted the Oracle team & they say that their RAC installation doesn't create any files in the / directory. This is the o/p of '/' directory file system:
Filesystem Size Used Avail Use% Mounted on /dev/mapper/datavg-vol2 498M 382M 62M 88% /
Also, when I checked the file sizes, I found that the following files were taking more space:
I don't know what these files are doing there, when I did a cat and cheked, I found the files containing this data:
nf_tre--
stem_dbusd_var_run_t...and some stuff like this Unable to decide whether or not to remove these files. Also, is there any way to find out what files are taking more space and whether they can be deleted or not? in order to free up some space in the / direcoty. As there are 10 RACs that we've build, I got to do something to fix this for all of the 10 servers.
What limits a file to have some maximum size depending on the Operating System? I do not exactly understand this. If you have the storage space, what else can be the limitation? You should be able to store as much data as you want the way you want (even in a single file) unless you run out of storage space.
is lvresize with --resizefs options re-size the Logical Volume and then re-size the file system? i mean we don't need to use resize2fs?I looked at man pages but it doesn't explain this option.
I just installed 10.04 to the second hard drive on my system, and stupidly installed the new grub to the first drive, which has my standard 9.10 OS on it. Now I cannot boot into my original system. All of the files across both disks are still intact and mountable. I'm not new to linux in general, but I'm not exactly knowledgeable, either...
I recently had my laptop which ran windows xp, wiped and ubuntu installed in its place. I was told of all the grand benefits of ubuntu so I thought yeesss. Everything was running beautifully, everything was heavenly, until i encountered "a flash website ". This was strange because ..... worked fine.
Anyway ever since I encountered that site Ubuntu crashes on startup. I log in then crash. Its strange because sometimes it takes a while to crash e.g. when trying to open any application, or sometimes its instant.
1. How i diagnose this problem so it can be fixed, remember it may have to be before the log in. 2. Is there someway I can do a system restore to its original settings or something?
we have a customer that ran a sudo chmod +x -R * command on his / filesystem by mistake and now the machine cannot be accessed on the network Has anyone any idea what chmod command to run to restore the system to its original state ?
I got a new laptop today and the first thing I did was to install Ubuntu as a dual boot with Windows 7. Everything seemed to work the first time I loaded Ubuntu after installation, and Windows also seemed to work. Then, Windows Maintenance said there was possible disk corruption, so I restarted the computer and now I get this error when trying to load. After reading around about similar problems I think it might be a problem with the grub bootloader. It is 64-bit if that makes a difference.
Ok, I have a Gateway Solo 5300 and I want to use it as a test server (install Ubuntu Server 10.10 and everything else after that.) The problem is I shut down the computer after it deleted the hard drive clean through installation and now I have to network boot because its old. What do I need to do that?
i planning to use ubuntu server as my operating system so that transparent proxy can be install using squid. i know that, ubuntu already has their own firewall that is linux ip table and but i want to use independent firewall that is pfSense since i need to install 2 transparent proxy in a network..see the diagram for details [URL]
is there is any possible, if i just want to use linux iptables at each transparent proxy server rather then using a independent firewall?
The issue I've been having is vague so I'm unsure if anyone can help me but it's worth a shot. The other day I was booting my laptop and this is what ended up happening and has continued to occur on successive boots:[URL] Each time it boots this is how the screen is characterized. For example: [URL] After this, continuing the boot process, the screen does this--which makes sense since the Kubuntu boot screen is this color and this where it should typically appear (I installed Kubuntu some months prior to this issue.): [URL]
After this screen, the monitor goes blank and becomes unresponsive. It usually flashes to black and then appears to turn on--becoming a slightly lighter shade of black.
Then, nothing. I can't go into tty. I've tried booting with a live CD but the issue persists and hangs, saying: soft lockup cpu 0 stuck for 61s. I've tried taking my laptop apart but I'm not familiar enough with hardware to do anything productive.
Is there any 32 bit operating system emulator (like a bridge) that I could easily use those packages or software that can be installed on a 32 bit operating system easier? Something easier than emulating another Ubuntu using Virtualbox.
I want to experience Ubuntu and want it on my machine. I currently have Windows 7 installed and was wondering what the easiest or best way is to install Ubuntu so I can choose to run either Windows 7 or Ubuntu.
ive installed ubuntu 9.01 on a external HDD. I have windows on my internal HDD and whenever I unplugged the USB HDD and turn on the computer I get Failed To Load Grub. I fixed this by restoring windows boot.ini file but now when I try boot from the external HDD (USB) it says Failed To Open Operating System and nothing else.
I have a serious problem with my computer. I had once shut down my windows forcefully( i.e. using the button) and now i am now not able to login to windows again. I tried installing linux from the booting cd but was not possible also. Now when I start my computer I get an error message. What to do?
I am trying to install Ubuntu 9.10 on an old IBM T21 laptop. It starts very happily, and I am able to partition the disk & copy the files to the HDD. However, when it loads the desktop there is an icon for the CD drive (and install disk). Everything appears to be fine, but I don't see any confirmation of the installation being completed. The CD drive does not open when the button is pressed. When I restart the laptop, I get the message 'operating system not found'. Starting the machine using the CD works fine. The disk shows that the partitions have been created, and I am told that Ubuntu 9.10 is installed.
I have Ubuntu 9.10 running inside Windows XP Home Edition SP3 with Wubi. Is there a way I can make the screen where I select what Operating System to boot into look nicer? I was thinking of something like the Windows 7 Background with 2 pictures, one of the Windows logo (would boot Windows), one of the ubuntu logo (would boot
