Ubuntu :: Need To Remove Some Things From System
Mar 31, 2011
I've been running Linux for about 3 years now. I still am having difficulties understanding some of the basic unix and linux software and their dependencies.
What I am wanting to do, simply for my own amusement, is to strip the OS down so that I am only running software that I need. Then I want to build it back up with X and some sort of desktop.
Right now I have a stock Ubuntu 10.04 installation from the alternative DVD. Right now I sit at 643MB and 14MB of ram. Of course I would want it to be lower.
Here are the programs currently on the chopping block. I need to now if I honestly need them or not. I state next to the software whether or not I know what it is. code...
So obviously I have not a clue about many things still, and if you've caught an error in my descriptions then I have less of a clue than I thought.
I just need to know what the system needs to run. I like the basic commands like less, grep, free, df, du, adduser, usermod, apt-get, dpkg, cp, mv, rm, mkdir, ect. What I don't need are things like w3m telnet(Unless someone knows something I don't), memtest+, and I don't ever use cron, but I also don't know if it does something behind the scenes that is vitally important. I remember trying to get rid of memtest one time and it wouldn't boot after that. Any idea why?

I've done some searching through google and can't seem to find a fix for this.
I installed skype on my computer and couldn't figure out where the tray icon went after i closed the main window so I started playing around with all my taskbars and stuff. Being new to ubuntu and all (I'm using version 11.04 with the gnome theme) i accidentally deleted the Skype icon, my windows list on the bottom and everything up top. I successfully restored my windows list and have system monitor so i can easily kill skype if i accidentally restore it (i haven't been able to figure out how to restore the icon up there) and got rid of all my stuff in the top right corner. Upon reboot everything returned except for my shutdown/restart/log off list which i loved (it fit in esthetically and had all the options).

I'm working through some problems in a beginners programming book. The author mentions a formula for calculating the number of ways of picking out n things from a collection of m of them:
Code:
/ m m!
| | = -----------
n / n! (m-n)!
But he does not give a name for the formula. Does anyone happen to know what it is called? I need to do some related research.

I decided to give Ubuntu another try and installed the Studio version. During my installation it asked whether I wanted the Realtime kernel or not. I chose yes as I figured it could come in handy when I work with audio.However since this version isn't exactly Ubuntu 10.10 as promoted , I decided to install Ubuntu Desktop on top of it (trough apt-get). For the full experience. ( im not even sure if it just installed extra software and added some folders)Now my questions are:1:The Realtime kernel is it now overwritten by any other kernel that came with the Desktop installation?
2: How will the updates handle my installation once i want to upgrade to, lets say, 11.04.I'm not really sure about how the system will look at things to upgrade. Will it look at my Desktop installation or my Ubuntu Studio? ( concerning the Realtime kernel as well).Just to add some more: I'm a total Linux Noob(although im not scared to use the Terminal)

Having recently installed Ubuntu 10.10, I'm currently looking around for different programs. However, it's already getting on my nerves that I have to type my password every time I want to install something. Where and how do I disable this? I already set myself as admin in the user settings but that doesn't seem to work.
This goes for things like changing system settings too, it's really annoying.

The latest update installed a new linux header 2.6.35-23. The older version 2.6.35-22 also appears in grub. What would be the sense in keeping them both? And if not required how do I remove the older version from grub?
I tried: "sudo update-grub" which changed nothing.

On 10.04, Lucid, I have a need to adjust the system menu for one of our accounts to remove the Log Out [Name] item. It's a rather embarrassing problem involving the nVidia driver, a laptop, a dock and dual monitors, where ending a gnome session sems to crash the video driver (or even the whole computer, I'm not sure) where I can adjust the contents of the system menu either for the whole system or for particular users?

I installed Skype only because it is necessary to Pidgin to handle the Skype service/protocol. I use Pidgin for many protocols included the IRC, so I don't need Skype icon in the system tray at all. Honestly I hate Skype, but unfortunately it seems that all the world use it. how to take off that terrible icon/indicator/applet from the systray. I searched in all system to find a configuration file, I opened few named Skype using vi to avoid to damage them, but I have not found nothing interesting for my scope. PS: don't tell me how I will switch on or off Skype, because a plug-in of Pidgin do it w/o user interaction.

I have apache2 on my system, and it stopped working since the router was messed with (not by me). I removed apache2 and deleted /etc/apache2, but if I install apache2 it doesn't bring the files back. How do I fix everything that I messed up so it's as if apache was never installed so I can install it again?

Okay, so my problem is that I can't get rid of some repositories on the left side of the Ubuntu software center.
I've gone to Edit > Software Sources and unchecked everything in Other Software, rebooted and still they remain. I then went into /etc/apt/sources.list.d/ and deleted the offending .list files, and they're still there. How do I get rid of them?

I had windows 7 starter, then repartitioned the HDD and installed Ubuntu netbook remix the partitions are in this order Ubuntu -> System -> Data partition -> Windows 7.I'm having some nagging problems with remix and want to try something else.Can I just destroy the Ubuntu partition or will it stop windows from booting up? I know Windows was there first, but the computer has been booting from the /boot/grub/grub.cfg menu, so when this is gone will it automatically check the windows partition for a boot.ini or whatever?

I would like to remove a specific domU (test01--pv--guest) from my machine. I am not sure how far/to what extent to remove files. Here are the files and properties it seems I should remove:
lrwxrwxrwx 1 root root 10 Jan 9 11:05 /dev/disk/by-id/dm-name-xenvg-test01--pv--guest--disk -> ../../dm-3
lrwxrwxrwx 1 root root 10 Jan 9 01:03 /dev/disk/by-id/dm-name-xenvg-test01--pv--guest--swap -> ../../dm-2
lrwxrwxrwx 1 root root 7 Jan 9 11:05 /dev/mapper/xenvg-test01--pv--guest--disk -> ../dm-3
lrwxrwxrwx 1 root root 7 Jan 9 01:03 /dev/mapper/xenvg-test01--pv--guest--swap -> ../dm-2
lrwxrwxrwx 1 root root 7 Jan 9 11:05 /dev/xenvg/test01-pv-guest-disk -> ../dm-3
The above link to dm-2 and dm-3.
brw-rw---- 1 root disk 254, 0 Jan 9 01:03 /dev/dm-0
brw-rw---- 1 root disk 254, 1 Jan 9 01:03 /dev/dm-1
brw-rw---- 1 root disk 254, 2 Jan 9 01:03 /dev/dm-2
brw-rw---- 1 root disk 254, 3 Jan 9 11:05 /dev/dm-3
brw-rw---- 1 root disk 254, 4 Jan 9 01:03 /dev/dm-4
brw-rw---- 1 root disk 254, 5 Jan 9 01:03 /dev/dm-5
brw-rw---- 1 root disk 254, 6 Jan 9 01:03 /dev/dm-6
brw-rw---- 1 root disk 254, 7 Jan 9 01:03 /dev/dm-7
Will they be deleted automatically or should/can I remove them? How do I check the need for the other dm-? files? As indicated below, it seems like some may be duplicates.
I also found this set in /etc/lvm/archive/:
-rw------- 1 root root 2909 Oct 17 00:41 Relaise-vg_00000-1453251236.vg
-rw------- 1 root root 2929 Oct 24 22:08 Relaise-vg_00001-1530642081.vg
-rw------- 1 root root 2924 Oct 25 19:33 Relaise-vg_00002-328450675.vg
-rw------- 1 root root 2901 Oct 26 19:53 Relaise-vg_00003-1555350964.vg
-rw------- 1 root root 2902 Oct 26 19:53 Relaise-vg_00004-1044927704.vg
[Code] ....
Some of these seem like duplicates. This may be due to multiple attempts to build the volumes. Is there a way to determine if all of the are useful?

I'm using Fedora 14. I need to install an older version of MySQL for some testing at work. To do so, I go to remove the existing MySQL 5.1.x that is installed - a dependency of Akonadi. Well, the ensuing chain of dependencies ended up essentially killing KDE. I don't suppose there is a convenient way to get KDE back without Akonadi? I really don't care if I have PIM storage services.

How to remove X completely from the system?
As a Security practice I wanted to disable X from loading.
So i modified following line from /etc/inittab.
id:3:initdefault:
I was then able to start my machine in terminal mode(runlevel 3).
I wasn't satisfied at this stage as i was able to get the graphical console by merely typing code...
Now i have made the above line commented and removed execute bit of the file .
System is now behaving as i wish it would.
I have 2 questions here.
1)Is this Method considered to be stardard while removing X in linux distro.
Will it make any difference?
I m not using any application that explicitly use graphical user interface and i can work in runlevel 3.
2)Is any package responsible for loading X .If yes then removing shall remove X from the system,correct me if i m wrong.code...

I have built a CentOS server, as many times before, and have has to move it to a new location/network. I had changed the virtual site that was configured with a virtual ip address on the same nic. I have since removed the virtual nic, checked my host files and network files and nothing now has the old ip address. I had issues I believed caused by dns or ip address so I finally uninstalled Apache. Reinstalled it. I still cannot access the site that was there. I have cleared all the data I can from the Firefox browser such as histoy. However when I go to "http://localhost" it says it cannot connect to the old ip address. WHERE IS THAT BEING SENT FROM??? It's driving me crazy. I really don't want to rebuild the server as there are other things that took some time to get configured.

The thing is, i'm getting thin on hd space so i have to remove it. I have read that i could just format linux partition and than boot with windows cd and fix motherboard, but i do not have windows cd on me. Can i use another tool, that would allow me to fix the "damage" grub did? Acronis or something like that?
To avoid to complicated answers, just give me a solution that works without criptic linux commands, i get lost in that.
Also, i am actually a supporter of open source and free software, but i also think that linux is nowhere near being easy to use for the general population, no matter the microsofts conditioning. So i guess ill give it a go at 11.00 again to see whats going on

I am very close to deploying Ubuntu 11.04 to my school and need to remove the access to the "System Settings" to the students. This is the last thing I want them to get at. I had 10.04 going but ran into other problems that 11.04 solved and allave left is this problem.I can lock them out of all those nasty options you don't want students to get to in a lab setting except for this

Since I'm running Sid. Let's assume package foo has been upgraded via apt-get dist-upgrade, and it causes a serious bug so that Sid is never able to fully start up, and is not even able to get me to the console to remove the package.
(Reword: let's assume that I upgraded the system despite apt-listbug warning me that foo had serious issues.)
Is it possible for me to remove the package and get back in? Everything I've seen online assumes that I could at least access console--but this hypothetical bug doesn't allow that.
If it were in Arch, I would just boot from the live dist, arch-chroot into the / directory, and try to remove foo via pacman. But Debian doesn't offer a live disk past Stable, so I suspect that this wouldn't work with a Wheezy disk?
Am I asking for an impossible situation, or can a troublesome package be removed from an unresponsive Sid?
