• How do I partition my Hard drive to install Kubuntu?

  - by Xdflames

  I am a complete newbie to partitioning and I would like some guidance here. Can anyone explain what exactly I should be doing here? I am installing Kubuntu 12.04 on a currently Windows 7 laptop. My current Partitions say this: /dev/sda /dev/sda1 ntfs 104 MB 35 MB /dev/sda2 ntfs 319965 MB 87164 MB Basically, what I want is some guidance on what exactly to do here. All I want is a partition for my OS (Which will be Kubuntu 12.04) and a partition for all of my data. I also want to restart fresh with my hard drive, with only what I mentioned on here. I am installing Kubuntu from a flash drive (I set it up as a bootable device with Universal-USB-Installer-1.9.0.9), as I do not have any blank CDs/DVDs to burn to. What should I name my partitions? What should I set the type as? What size do they need to be? Edit: My hard drive is 320GB. Just looked it up in my BIOS. This computer will mainly be used for internet browsing and overall just messing around with the Linux OS.

• Is it possible to code on two different computers simultaneously?

  - by Muhammad

  I want to work with another programmer and I want the source code to be live in real-time on both of our screens. Is this possible on the Mac OS x or Linux? We're going to be using OS X but occasionally we might need to add an Ubuntu computer too. Is there a way I can do this using ssh, any shell based program, or even a good GUI? I thought Coda might be capable of this but it's not really working. Anyone ever do this? I'm not look for a git/svn/or any other version control system. This is more of a live coding session. :)

• backuppc - how to backup remote (over the internet) clients?

  - by Scott

  I am testing out backuppc, which works great so far backing up windows clients on a LAN via SMB (no backup client/agent required). However I have quite a few laptops and desktops that are in various remote locations - some of which move around. I need some way to have that remote computer create an outgoing connection for backup purposes (Windows XP/7). I know backuppc supports smb, rsync and 'tar', but I believe these are all connections going from the server TO the client. SO, I either need a way to vpn the client on a timed basis, or it would be a lot better if the client could some how connect to the server (ssh?) and initiate it's own backup somehow (rsync?). Of course this all needs to be pre-installed by me and require no maintenance by the end user, no dialogs on their side. What do you think?

• Is it possible to replace the Logitech G500 wire without rebuying the mouse?

  - by leladax

  It has to be replaced ideally in whole, from the point it starts inside the mouse (with a white 4-5 piece of wires connection) to the end (of the USB connector to the computer) or at least to a considerable length because there is fatigue very near the mouse and the more I fix it there with soldering the closer it gets to being unfixable or reaching towards 'inside' the mouse where fixing it will be hard or impossible. So I wonder if there is a way to get a replacement of the whole thing or at least the inside-the-mouse connector to a certain length. Also I wonder if other mice types are identical in the connector of the inside.

• Why does OS X automatically logout my user?

  - by MBA_fv

  I have a new MacBook Air set up with filevault. In the Security preference pane I have "Require password 1 hour after sleep or screen saver begins" enabled, but the "Logout after 60 minutes of inactivity" is disabled. When I leave the computer on overnight I manually lock the screen (from the Keychain status menu bar, which I enabled via the Keychain Access preferences). Alas, in the morning I find that instead of a locked screen I see the login window, after my user was logged out with all applications terminated... (e.g. Firefox thinks it previously crashed when I launch it). This type of behavior only started after I enabled Filevault. Why is this happening? How do I prevent such auto-logout?

• How can I prevent a Windows laptop from making noise when starting up?

  - by Walkerneo

  I have a Windows 7 laptop here that makes a noise each time it starts up. I know I can disable that noise now that I'm logged on, but how could I have prevented it WHILE logging on? I remember that there was one of the function keys (F8?) that would allow you to boot into safe mode, but is there a key that will stop the startup sound? Imagine, for example, having your laptop in the library when you know the volume is all the way up - how could you log into your computer without disturbing everyone else?

• Why can't I create a Windows backup on my secondary disk?

  - by Brian Sullivan

  I've installed Windows 7 Ultimate on an SSD that I've added to the XPS desktop that I bought from Dell. I would like to use the built-in backup functionality to create incremental backups and store them on the large drive that came with the machine. I formatted the large drive and turned it into a Basic disk. However, when I try to set the backup location to the large internal disk (E:\) in the "Set up backup" wizard, a get a message saying, "A system image cannot be saved on a drive that your computer boots from or that Windows is installed on." Windows is not installed on that disk. I even deleted the OEM partition that was on the disk, and removed it completely from the boot order in the BIOS. Any clue why Windows is griping at me about this?

• Is there any way to facilitate switching windows in Ubuntu?

  - by Ivan

  I'm just a student who received my laptop from my uncle, who's a coder, so I'm still getting used to working with ubuntu. I recently upgraded ubuntu from an earlier version, and everything seems to be pretty great. The only thing is that when I open a program, or file, or whatever, it takes up the whole screen. I can only close it by going to the far top left of my screen, or by ctrl+W. Anyways, I find it really hard to switch between programs. For example I really like to have my windows that are open to be accessible by clicking on their icon at the bottom of the screen... Great when writing or researching. Anyways, I really just want to find an easier way to switch windows. Also, I used to love the way I could cube-rotate my screen, and just drag files from one desktop to another, with compiz. Now, its sort of like flipping a coin when I switch windows, is there any way to get my desktop cube back? And yes, I have enabled all the old settings I used to use with compiz. Sorry if what I'm asking is very basic, I know how to use a computer, I'm just not really familiar with the interface! Any help is greatly appreciated.

• Why is my disk full?

  - by Agmenor

  I installed Ubuntu 12.04 by doing a fresh install where there was previously Ubuntu 11.10. My computer warns me now that my disk is nearly full. After having run apt-get purge, run apt-get autoremove and emptied the Trash can, I still have this problem as shown by this screenshot of Gparted: The disk /dev/sda7 is indeed full. I ran the Disk Usage Analyzer (Baobab) and I am still not sure of what is happening: One of my hypothesis is that when installing Ubuntu 12.04, I didn't configure my disks well and the disk /dev/sda6 is not mounted well as /home. Is this the reason indeed? What should I do to verify this and then to get the things fixed? Here are a few additional details to answer the questions I received (thank you everybody): My home directory is not encrypted. The Backup utility (Déjà Dup) is not set for automatic backups. (I do it myself and manually.) After I mount /dev/sda6, the command df -h gives Filesystem Size Used Avail Use% Mounted on /dev/sda7 244G 221G 12G 96% / udev 3,9G 4,0K 3,9G 1% /dev tmpfs 1,6G 904K 1,6G 1% /run none 5,0M 0 5,0M 0% /run/lock none 3,9G 164K 3,9G 1% /run/shm /dev/sda6 653G 189G 433G 31% /media/8ec2fa69-039b-4c52-ab1b-034d785132a1 (sorry but formatting this into code does not work, for an unknown reason) Thanks to izx's post, I realized /dev/sda6 was not even mounted before. It contains all the documents I used to have when I was running Ubuntu 11.10.

• Trying to turn an WD Mybook 1TB to slave drive in PC

  - by Steph W

  Yes I realise that most external Hard Drives would not be transitioned into internal sitting Hard Drives, but unfortunately we broke the miniUSB connection that transfers the data from external Hard Drive to laptop. What we are TRYING to do now, is get the WD MyBook 1TB to funtion alongside (preferably as SLAVE) to my currently exsisting Desktop Hard Drive. both are SATA drives. We have the SATA power, and Data cables, and these are in place (but - somehow NOT working) - Help please - I am not computer illeterate, just don't know how to switch this so it works. How do I turn one into master, and the newer one (that was external) into the slave drive?

• What are my X client options for MS Windows?

  - by Nick Bolton

  I need to connect to a headless X Windows server (running on Ubuntu) from my MS Windows 7 computer over a 100 Mbit network. I could use VNC (or any other remote viewer) but the 3D graphics performance would be lousy I imagine. I used to have it hooked up to a monitor, but that's broken now and I can't afford a new one. A friend advised that I could try and use an X client, and that the 3D graphics wont suffer too much over 100 Mbit. Cygwin seems to be an option, but I was wondering if there were any more lightweight options.

• is there any way to lock few Windows Registry enteries

  - by Moorage

  I have seen that most of virus , spyware etc changes few registry files which are linked to boot process or which starts when window loads user settings. Is there any way to lock those files which are linked to start the system like explorer.exe , userinit.exe so that virus at least should not be able to stop the system to start up. Why did'nt microsoft put those registry file separately so that nothing can touches them Now my userinit.exe file is affected and its not letting me logn on to computer. I get blank desktop but system loads during safe mode. I have run anti virus bootable cd but still have not found solution

• How do I determine which HD is involved in the Event Viewer?

  - by Rod

  My PC apparently crashed before I came home from work (so my daugthers tell me; they rebooted it). The first thing I did, after it came up, was got into the Event Viewer to see what it said. Several hours before they rebooted it, there's a message in the event viewer that says: The driver detected a controller error on \Device\Harddisk5\DR5 I've no idea what that means. I got into Computer Manager, to take a look at the disks on my machine. There's only 1 hard drive, and a few slots for microSD, etc, but none of them are labeled "Harddisk5", nor is there anything there labeled "DR5". How do I determine what, if anything, those are? Could they be USB drives that my daughters used?

• List and kill running processes on Mac OS in Ctrl/Alt/Delete-like way?

  - by AP257

  So, what do you do on a Mac when a process (as opposed to an application) is hogging CPU, swamping your machine, and you need to kill it? I know you can use top or open Applications > Utilities > Activity Monitor and kill it from there. But what happens when the process is already using so much CPU that doing either of those tasks is impossible? On Windows, you can just do Ctrl/Alt/Delete and the process list will reliably open. So no matter how much your computer is thrashing, you always have access to the list of processes. On Mac OS, there's Cmd/Alt/Escape, which reliably shows running applications. Fine when it's an application causing the problem. But: what do you do if it's a process?

• Why does deleting from the command line take significantly less time than from a GUI?

  - by Jordan Plahn

  So this is probably the dumbest question you'll read today, but it's something I just wondered about as I was deleting a dozen or so images from my computer. With a quick rm -rf command on the directory's contents, all the images were gone in a snap. When I drag the same dozen or so images to a trash can/recycle ban, it takes sometimes 10 seconds or more. Now I'm sure some of it comes from the overhead of the GUI and such, and some of it may be the fact that the file still "exists" in some form if it's put into the recycle bin, but is there anything else that accounts for such a huge time disparity? Are "rm" and "delete" just such fundamentally different commands so I'm trying to compare apples and oranges? Enlighten me, please!

• Manually forcing TCP connection to retry

  - by Vi.

  I have a TCP connection (SSH session to some computer for example) Network suddenly goes down and drops all packets (disconnected cable, out of range). TCP resends packets again and again, retrying with increasing delays. I see the problem and plug the cable back (or restore network somehow). TCP connection finally successfully resends some packet and continues. The problem is that I need to wait for a some timeout on point 5. I want to use my opened SSH session now and not wait for 5-10 seconds until it finds out that connection is working again. How to force all TCP connections to resend data without delays in GNU/Linux?

• How to configure something like "Reflexive ACL" on OpenBSD?

  - by Earlz

  My U-Verse modem has something called "Reflexive ACL" described as Reflexive ACL: When IPv6 is enabled, you can enable Reflexive Access Control Lists to deny inbound IPv6 traffic unless this traffic results from returning outgoing packets (except as configured through firewall rules). This seems like a pretty good way to keep from having to maintain a firewall on each computer behind my router that gets handed an IPv6 address. It sounds about like a NAT, which for my small home network is all I want right now. Now my modem sucks as a router though, so I'm in the process of configuring an OpenBSD router to do that. I've got IPv6 supported and all that and my OpenBSD router will hand out IPv6 addresses by rtadvd. Now I want to keep people from having instant access to my local network through IPv6. How would I best do something like Reflexive ACL with pf in OpenBSD 5.0?

• Google Chrome giving error 138

  - by gsingh2011

  Google Chrome randomly stopped working one day and is giving me this error: Google Chrome is having trouble accessing the network. This may be because your firewall or antivirus software wrongly thinks that Google Chrome is an intruder on your computer and is blocking it from connecting to the Internet. Here are some suggestions: Add Google Chrome as a permitted programme in your firewall or antivirus software's settings. If it is already a permitted programme, try deleting it from the list of permitted programmes and adding it again. Error 138 (net::ERR_NETWORK_ACCESS_DENIED): Unable to access the network. I didn't make any changes to my firewall settings between the time it was working and when it wasn't working. I'm using the default Windows Firewall. I added Chrome to the allowed programs and restarted, but that didn't fix the error. I even reinstalled Chrome completely and that didn't work either. Any help would be appreciated. EDIT: I forgot to mention that Firefox and IE9 work fine.

• Keyboard layout to shift wasd keys

  - by Joel Coehoorn

  I like to play video games on my computer. One of the things that bugs me, though, is how the wasd keys became the standard movement keys in first person shooters and mmorpgs. To me, esdf makes a lot more sense, because that matches your normal hand placement for typing. "Fixing" that layout is always the first thing I do when installing a new game. Sadly, this is often a pain in the neck, and some games won't let you do it at all. Is there an alternative keyboard layout you can install that will just switch these around, so the wasd keys fall in the esdf positions? And is low-level enough two work with DirectX/DirectInput, perhaps that works with the language bar for easy swapping back and forth?

• Why do most routers not include local DNS?

  - by user785194

  I need to change my firewall/router, and I'd prefer something with built-in DNS to resolve queries on the local subnets. I've got a mixed Linux/Windows system, often with only one computer turned on, and I frequently have problems resolving local names. I don't want to keep a Linux box permanently on just for DNS, and I'd prefer to have DNS in my router appliance, which is always on. I search Google for this occasionally but never find anything. You always get the obvious answers - it's not possible, put everything in /etc/hosts, NetBIOS, dedicated box, etc. So what am I missing? Why don't "cheap" routers let you do this? I'm pretty sure that Cisco kit does this. Almost all cheap routers will let you do MAC address reservation, to let them assign static IP addresses for DHCP. So why can't they simply do DNS as well for everything on the local subnets, just passing through remote domains to the ISP?

• Over-scan Issues when using HDTV through VGA

  - by RPG Master

  Right now all we can do is set the TV to 1280x768 instead of its native resolution of 1360x768. Setting it to its native resolution gives you a screen with a large portion of the left side of the screen cut off. We've tried everything with the TV so now we're turning to the innards of Ubuntu in hopes of fixing this. The computer is using an NVIDIA GeForce GT240.

• Ubuntu black screen after Installation of 12.10 Live USB

  - by Lime0fHint

  My computer was made in 2004, but I'm sure it doesn't matter since it's a durable machine. So recently, I decided to breathe new life to it with Linux. I tried Lubuntu 12.10, Nope. Black screen after install. So I tried Ubuntu 12.10 when I gave up, and same exact thing. Except, this time I'm fighting for it, since Ubuntu is the best OS I've ever seen. So back on-topic, when I start the installation, it says that something is already mounted (Sda or something of the sorts) So I just figure that it's the Live USB I'm using. So I let it ignore it, and move on. The rest of the installation goes smooth, all looks fine. Then I get to the screen with the introductory to Ubuntu. Meanwhile, it's still installing, but finishing up. I'm not sure if the install actually finishes, but I do know that after a bit, the screen goes back to the desktop. The install closes and I'm back at the desktop, and the cursor is showing the "loading" symbol, as if it were still working. Then the screen goes black, with the same cursor. After that, nothing. I left it over night like that thinking it was doing something, in the morning it was still black with the cursor circling or whatever. So what could be causing this? One concern I have is that I have a Nvidia graphics card (7300 GT). I heard that Nvidia isn't compatible with Linux? I did notice that it was marked as unreconigsed by Ubuntu, so is that the problem perhaps?
