General :: Important Knowledge Of Changing OS From Windows XP To Ubuntu

Oct 17, 2010

nothing informative from me as of now, although I have only been out of "Windows" for a little less than a day, I suppose the only alternative conversation topic is a simple request for those more experienced users to point out some major/musts about topics to focus on as I'm new to open source ANYTHING, really

To think I was so "under the gun" about spending loads of cash to keep up with the IT group of choice, I have gained some much needed relaxation w/my cup a tea. Pinpointed request, I guess, "when you first started, and knowing what you can do with it now, would you be obliged to say 'HEY, THIS IS THIS, BUT WATCH OUT FOR THIS'

General :: Ways To Get In-depth Knowledge Of OS

Jun 21, 2011

I'm currently trying to find ways to get in-depth knowledge of the Linux OS. To give a brief overview of where I am at right now, I am a computational science graduate student who does all of his work on *nix scientific clusters.I also took a lot of computer engineering and computer science courses in college, as well as being the stereotypical standard computer nerd growing up, so I'm somewhat familiar with computer architecture, though more from the hardware side.So I'm familiar (though I wouldn't claim to be an expert quite yet, by any means) with using Linux and C programming, and I have a basic grasp of generic computer architecture, but what I feel I really lack knowledge in is the specific details of the Linux. All the details of the boot process, exactly what the kernel does, how Linux handles memory management, etc. I'm having difficulty finding any information on this;all I can find is generic information targeted towards people who are just starting out, and the stuff I've found that talks about the kernel seems more oriented towards "you change setting X and Y happens" rather than what the kernel is doing.

General :: Focus On Command Line Machine System, Network Basics, And File Management Knowledge?

Feb 17, 2011

As a strategy for learning linux I have decided to adopt using a lean windows based approach. I want to focus on command line machine system, network basics, and file management knowledge. In other words find out how desktop manager does it's business, so I know how to master my machine, but by and large once I have made my choices, leave it alone to do just that.

I figure I should know how applications are internally configured etc., but I also figure an apps GUI and config choices should take care of installations, and program usage as in M$ windows. Surely taking care of an applications dependencies are the responsibility of the developer, are they not?

I am working my way through "Rute User's Tutorial and Exposition (Version 1.0.0)" right now for an overall viewpoint. Can anyone suggest a specific source for a point by point explanation of the command basis of a generalised "desktop management" application (KDE,LXDE)? Better yet would be if it had some parallel comparison of the varied approaches taken by different distributions of linux.

A secondary question, is that allowed? Up to a certain point in Ms windows, a thorough knowledge of DOS 6.xx would theoreticaly enable one to more or less duplicate the actions of the windows overlay. Is there a basic distribution (or subset in all of them maybe?) of linux that would be consistent with that paradigm? What would be analogous to DOS batch files, or GM-Basic? Oh! that's 3.I am certainly appreciating the depth of this forum, and the breadth of knowledge among you forumite's. Reading it is time well spent.

Ubuntu :: Remove All 'knowledge' Of Nvidia

Mar 5, 2011

Running 10.10. My graphics card has just blown up so I've had to switch to the motherboard internal graphics. Problem is, Ubuntu doesn't like it - I have to start in recovery mode and 'low graphics for this sesion'. How do I remove all 'knowledge' of Nvidia and then let Ubuntu configure itself for my new(!) graphics capability?

General :: Most Important Directories To Backup On A Server?

May 21, 2010

I'm running an Ubuntu 9.10 Linux server. I'm trying to find a way to backup the machine while it is running and from what I see, this eliminates the disk clone utilities. All of the disk clone stuff I have seen for Linux requires that you reboot into a special live CD.So my question is this, what is the best solution for backing up the system while it is running? Also, I don't really care about the OS config too much, I just want to be able to keep my stored files and my programs that I have installed on it.

General :: Live CD To Recover Stored Important Scripts?

Feb 21, 2011

My system got crashed yesterday. Before I do any mess up with it I would like to backup some important scripts stored in it. With so many live cds available I am confused which one is to choose. It should not be too big (in terms of mb). Any small Live cd will do.

Ubuntu :: Resize Partition Scheme Lack Of Knowledge The Cause?

Jan 26, 2011

I setup a dual boot system, with approximately 200gig planned for ubuntu 10.10. Based on the article here:[URL]..And this quote:

Quote:

# sda1 Recovery Partition, unchanged
# sda2 Windows partition, shrunk preferably from inside Windows, hopefully about 30Gb
# sda3 Primary Partition, 10Gb, file-system = ext3, in the Partitioning Section of the installer change the "Mount Point" = /

[Code]...

I assumed at that point that the "sda3" "/" would be for booting purposes. I would have to guess that I was wrong, because it is filling up very quickly. As you may be able to tell by the screen shot, "sda5", "/home" was what was assumed to be the file structure to store all of the programs and such.

I have only been running this setup for a week, and would expect to not be seeing my "boot" partition growing so quickly. Do I need to resize it? here do the standard programs that I get from the ubuntu software center install at (partition wise)? I suppose I dont mind wiping that section dry and starting over, but I would give a resize a try if possible.

General :: Extended Partition Is No Longer And It's Full Of Important Stuff

Apr 19, 2010

I'm sure I've done this before and never ran into trouble so it's not like I wasn't thinking, just something went wrong this time and I'm screwed. I'll post a fdisk -l to show ya what I mean.

[root@localhost ~]# fdisk -l /dev/sda
Warning: invalid flag 0x0000 of partition table 5 will be corrected by w(rite)
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x624aa2e0

[code]...

Well I tried to install Pclinuxos 2010 to the same partitions as Mint 7 and basically just over write it (this I have done before) but this time Pclinuxos says there is a bad block and it can't copy files to / (sda7) I didn't think much of it at the time and thought I would try to install it (Pclinuxos) on a separate 100 gb usb drive and it was a sucessful install.

After booting Pclinuxos I try to access my 1TB sda hard drive and I can ony access sda1 .....when I look at /dev/sda in gparted is shows the whole disk as unallocated.I have done nothing at this point in time other than what I just said because I am very afraid of loosing all my pictures and everything else on that disk....and for those that will say always back up ....if ya think I'm not kicking myself right now your dead wrong......

General :: How Important Is 'CLUE' / Command Line User Environment?

Oct 16, 2010

I have read many articles by eminent Linux users who laugh off, when they are asked "is a command line knowledge necessary"?. They go on to say that Linux Distros have evolved so much that the GUI is sufficient! I use my Win.desktop for 1)checking the news, 2)checking my e-mail, 3)writing a blog, 4)Listening to music, and 5)since i am a consultant physician, with specialization in diabetology,keeping up with the trends by visiting a few professional websites! So, my needs are few!Which Distribution would you suggest to a completely Linux-ignorant person,and that's me!

Data flow has become nowadays really huge. Although how hard one can try to tide folders, hard-disk, it can always be some days you are looking for something. What could be interesting to make available, e.g. to install for users, on all Debian stations. In some universities, with Linux-machines network, it is often kind of obliged to use emacs and 'office' KDE applications, as a standard at first.

for organizing better, what could be the solution as 'data flow organizer'? Many solutions, many methods, many ways are offered but none will be perfect

Ubuntu :: Changing Size Of Windows?

Aug 2, 2010

Whenever I try to change the sizes of the windows on my screen I get a cursor which is a double arrow. There seems to be only one X- or Y coordinate on the screen where I can pick the side of the window, it seems to be only one pixel wide. This makes it hard to get hold of the side to change the size of the window. Is there a way to enlarge this location to a few pixels so it is easier to point the mouse to the right location?

I'm just setting up a partition on a seperate HDD in my system. I plan to use the partition to backup the important files on my main HDD (to guard against HD crash).

The question I have is about where would be the typical location to auto mount this partition? Which would it be normal to go for:

1. /backup/
2. /media/backup/
3. /mnt/backup/
4. /home/chris/backup/

Ubuntu :: Changing Default OS To Windows In GRUB

May 17, 2010

I've seen previous threads about this, but they're rather old and I can't seem to apply their solution to the latest (10.04) stable release of Ubuntu.

What's the "best" way of changing the default option in the bootloader? I'd rather set it to "Windows 7" for the time being as it's what I use at work.

Ubuntu :: Changing Icons In OpenBox Windows?

Aug 7, 2011

I've been trying to change some of the icons in my system. I first tried the GUI. This changed the icon in the start menu, on the panel, and on the desktop, but it doesn't change the icon in the left-hand corner of open windows or in the task bar in the panel. I then went in and did it manually by editing the .desktop files in /usr/share/applications. Same thing...the icons in Openbox windows are the old ones. My guess is that Openbox is looking elsewhere for icons, but I dont really know.

At the gnome login screen, the users have to click "other" and type in their windows username and password.

Installation :: Changing The Hard Drive Space On Windows XP And Ubuntu 9.04 Partitions?

Sep 14, 2009

I installed Ubuntu 9.04 on my latop. I have an older 80 gig HP laptop with Windows XP. Currently, i have XP as the NTFS drive and it takes up about 72 gigs of space, the swap drive for ubuntu is about 256 MB and the ext-3 drive is 2.5 gigs. However, i have no more hard drive space to run or instal any programs on Ubuntu. So what i need to do is decrease the NTFS drive as i still have over 30 gigs of free space on my laptop and increase the ext3 drive to about 10 or 15 gigs and increase the swap drive?

Ubuntu :: Important Files - OS X Won't Boot

Mar 11, 2010

i was working in this Macbook (its my mothers i do not use apple very much), just looking at ..... and normal stuff. no installations or anything, only used my external harddrive. Next time i turned on my computer, this weird gray screen showed up with something written like "kernel mismatch from your hardware" or something like this, i panicked and didnt know what to do so i restarted like the message in multiple languages said so. Nothing happened.

I tried to boot from CD (press C key) and it worked so i went on disk utility and looked for errors but all says fine. I tried making a copy of the Macintosh HD to my external hard drive so that i could re install mac but after a while copying it stops and gives me an error saying "operation not supported". I asked a professional and he suggested using a live cd of Linux (ubuntu 9. ) to try and retrieve my files from there. I did this and the live cd worked and i could see into all my folders but when i went to /Users/myuser/ none of those folders would let me copy, open and see the files. Desktop is where the important data is. It gave an error file permissions. I cant compress, open, see the files nor copy them. This is very annoying as the files are extremely important and i cannot do anything to delete them.

500gb external hard drive
Macbook Pro
Linux Ubuntu

Apple Original Install DVD (Snow Leopard) way to retrieve these files and copy them onto something. I really need this with urgency.

Ubuntu :: Won't Load - Can't Access Important Files / Fix It?

May 15, 2010

On my laptop I have a dual boot of Vista and Ubuntu (Karmic Koala). I have 3 Vista partitions and 1 Ubuntu partition (well, two if you include the swap disk).

Recently I had started to notice that when trying to boot into Ubuntu, it simply wouldn't. It would have a screen with lots of text which would every few seconds refresh yet it never really looked any different, although I'd be unable to tell. I'd leave it there for several minutes and nothing would happen.

I wasn't worried for a while because I only used Ubuntu for some scientific work over the summer and I haven't needed it for a while but now I desperately need those files. I've tried three programs that apparently make Linux partitions accessible in windows but I've been succesful with none of them. I'm now seriously worrying that there has been a harddrive error of sorts...but then I only have one physical harddrive on my laptop and my windows partitions are working okay.

I found my Karmic DVD and I tried to run "run Ubuntu without changing your system" but that wouldn't load after ages.

I haven't tried to reinstall Ubuntu because I've read that doing so would wipe the existing files.

Ubuntu :: SPM / UM Trying To Remove Important Stuff During Upgrades

Aug 25, 2010

(SYN=Synaptic Package Manager; UM=Update Manager)
Some reason recently the Update Manager has been saying it can only do partial upgrades, then it asks if I want to confirm the things, I look at them, they have a few set to upgrade, it also says it will remove certain packages that pretty much would render my computer useless.

Here's a screenshot of the box I took just a few seconds ago when I went to "Mark All Upgrades" in Synaptic Package Manager. You can see that wanting to remove important things like "ubuntu-desktop" and "network-manager". [URL]

I mean, I would love to upgrade my WebcamStudio etc to check out the newer version, but I'm not gonna upgrade it if I can't even access it! I'm planning on going back and manually checking the ones shown for upgrade after I get done posting this, and seeing if it might be a certain package.
