• When I type " nothing comes out, and if I type it again, 2 of it comes out as such: ""

  - by Pacerier

  Something is wrong with my keyboard?: when I type ", nothing comes out, and if I type it again, 2 of them come out as such: "". Same goes with the ' key. The first time I type it, nothing comes out, then if I hit it again two of them appear (so I have to backspace one of them everytime). I've got no idea what I did to my computer, it was working properly yesterday. (I think I was messing around with the language thing, however I've just undid everything I've did and its still not working.)

• Touchpad issues on HP Pavilion dm4 (can't right click)

  - by Habstinat

  Can anyone help me with my touchpad issues? I have a HP Pavilion dm4 and it has two areas on the bottom of the touchpad to designate right and left clicks. This mostly doesn't work on Ubuntu in the fact that it recognizes any taps on either tap zone as a left click. Instead, I have it set so if I tap anywhere on the pad it makes a left click. There should be, and there are, many ways in the mouse configuration window to simulate a right click using only a touchpad. None of these work. Changing mouse orientation doesn't do anything, "dwell click" also does nothing, and, the oddest part of this problem, whenever I try to turn "Simulated Secondary Click" off (it doesn't work anyways, but just to try to toggle it), the entire theme of my desktop changes to a gray Windows '95ey look. The only way to get rid of this is to close and reopen the mouse preferences window. My computer is fairly new and the Ubuntu installation is less than a day old. I didn't do anything that I think could cause this. The problem is that I can't right click. Help, please?s that I can't right click. Help, please? Afterword: I installed two scripts from http://sansmicrosoft.blogspot.com/2010/10/pavilion-dm4-1160-erratic-touchpad.html . They didn't do anything I couldn't already do, and they did not make it possible for me to right click. :(

• Unable to start after 13.04 > 13.10 udate

  - by romainl

  At the end of the update process, clicking on the Restart button had no visible effect whatsoever. After waiting 5 to 10 minutes, I decided to reboot the computer manually. Since then, I rebooted a good dozen times (not with the hope that it would work but with the hope of reading the messages) with the same non-result and the same symptoms: I get the ASCII text-on-purple Ubuntu 13.10 . . . . splash screen with these messages: * Restoring resolver state... [OK] * Starting crash report submission daemon [OK] * Starting CUPS printing spooler/server [OK] Everything disappears. The whole process hangs at a purple screen with the mouse cursor right in the middle. At this point, I'm unable to use the mouse and the keyboard. Booting from a 12.04 CD works perfectly, Disk Utility says that all my disks are OK and I can mount my main partition without problems. Something obviously went wrong at the end of the upgrade but I have no idea what. I'd appreciate any pointer. This is the kind of moment where you really think "Next time, I'll separate my /home partition for sure". My machine is an aging but working Dell Inspiron 530 with an Intel Core Duo E2160 processor, 2 GHz of RAM and an ATI Radeon HD3650 video card. Thanks.

• Win7 and Ubuntu refuse to coexist

  - by Jeremy

  I'll make this quick: I have an HP laptop with win7, I installed Ubuntu on a separate partition, and when I tried to boot win7 from grub I got the loading screen and no progress-ever. I did a /fixmbr with the windows recovery cd and got back windows, but wiped out grub and my access to Ubuntu. I reinstalled grub from the Ubuntu live usb ( I know I did this correctly) and now windows won't boot, again. I'm a linux noob at a loss. Your wisdom is greatly appreciated! Update in response to Scott Severance: your instructions say to determine the main partition on my computer. I'm not sure what this means... my windows partition is at sda2, my boot partition is at sda1, and my linux root partition is at sda7... Which is the "main" partition? UPDATE: I determined that you were probably referring to the linux root(/) partition, because this was the only partition for which I could follow your instructions without errors. Now, Windows is booting fine (thanks to /fixmbr), but even after the grub instructions there is no grub. It boots straight into windows.

• Looking for a video media player program that saves colour/volume profiles for individual videos?

  - by verve

  I use VLC right now but I'm tired of having 24 VLC players open because I watch that many different things each week so I just leave them open indefinitely; having to set each one up with the different colour/brightness/volume when the computer crashes is time-consuming. Also, having those many players open gets crazy. Is a good video media player available that lets you create or save profiles for videos watched or going to watched such as colour/brightness/volume? Windows 7 64-bit. Freeware or paid?

• Most secure way to access my home Linux server while I am on the road? Specialized solution wanted

  - by Ace Paus

  I think many people may be in my situation. I travel on business with a laptop. And I need secure access to files from the office (which in my case is my home). The short version of my question: How can I make SSH/SFTP really secure when only one person needs to connect to the server from one laptop? In this situation, what special steps would make it almost impossible for anyone else to get online access to the server? A lot more details: I use Ubuntu Linux on both my laptop (KDE) and my home/office server. Connectivity is not a problem. I can tether to my phone's connection if needed. I need access to a large number of files (around 300 GB). I don't need all of them at once, but I don't know in advance which files I might need. These files contain confidential client info and personal info such as credit card numbers, so they must be secure. Given this, I don't want store all these files on Dropbox or Amazon AWS, or similar. I couldn't justify that cost anyway (Dropbox don't even publish prices for plans above 100 GB, and security is a concern). However, I am willing to spend some money on a proper solution. A VPN service, for example, might be part of the solution? Or other commercial services? I've heard about PogoPlug, but I don't know if there is a similar service that might address my security concerns? I could copy all my files to my laptop because it has the space. But then I have to sync between my home computer and my laptop and I found in the past that I'm not very good about doing this. And if my laptop is lost or stolen, my data would be on it. The laptop drive is an SSD and encryption solutions for SSD drives are not good. Therefore, it seems best to keep all my data on my Linux file server (which is safe at home). Is that a reasonable conclusion, or is anything connected to the Internet such a risk that I should just copy the data to the laptop (and maybe replace the SSD with an HDD, which reduces battery life and performance)? I view the risks of losing a laptop to be higher. I am not an obvious hacking target online. My home broadband is cable Internet, and it seems very reliable. So I want to know the best (reasonable) way to securely access my data (from my laptop) while on the road. I only need to access it from this one computer, although I may connect from either my phone's 3G/4G or via WiFi or some client's broadband, etc. So I won't know in advance which IP address I'll have. I am leaning toward a solution based on SSH and SFTP (or similar). SSH/SFTP would provided about all the functionality I anticipate needing. I would like to use SFTP and Dolphin to browse and download files. I'll use SSH and the terminal for anything else. My Linux file server is set up with OpenSSH. I think I have SSH relatively secured. I'm using Denyhosts too. But I want to go several steps further. I want to get the chances that anyone can get into my server as close to zero as possible while still allowing me to get access from the road. I'm not a sysadmin or programmer or real "superuser". I have to spend most of my time doing other things. I've heard about "port knocking" but I have never used it and I don't know how to implement it (although I'm willing to learn). I have already read a number of articles with titles such as: Top 20 OpenSSH Server Best Security Practices 20 Linux Server Hardening Security Tips Debian Linux Stop SSH User Hacking / Cracking Attacks with DenyHosts Software more... I have not implemented every single thing I've read about. I probably can't do that. But maybe there is something even better I can do in my situation because I only need access from a single laptop. I'm just one user. My server does not need to be accessible to the general public. Given all these facts, I'm hoping I can get some suggestions here that are within my capability to implement and that leverage these facts to create a great deal better security than general purpose suggestions in the articles above.

• I want to easily switch accounts for Twitter - is there a Firefox/Chrome/IE plug-in to do this?

  - by Edelcom

  I have several Twitter accounts to which I post messages. One is a personal, one is a professional, and a couple for each software system I developed. Does any one know of a plug-in for one of the major web browses on Windows or program that allows me to easily login to multiple Twitter accounts and easily switch between them ? I now have the 4 major browsers installed on my computer , each with it's own Twitter account (with the password and login info saved), but I think there must be a better way. On a side note: it is getting harder and harder to know to which StackOverflow alike site a question must be posted. So I hope this question here is considered on-topic.

• 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 now in GNU/Linux?

  - by user5978

  Hello everyone. I have a slow computer. When I click on an icon say Firefox it can take 10 seconds to load. when I minimize and maximize windows you can see it happening. I get "ghost" screens where you see the window outline of the box but nothing in it or it may be white. The laptop is two years old and has these specs: Intel core two duo 2.8GHZ CPU 4GB RAM 500GB HDD 512MB Nvidia 8600GT video Realtek HD audio What is going on and where should I start looking for issues? Ubuntu 10.10 was upgraded from 10.04LTS following the instructions from the Ubuntu Wiki and it was done through the update manager GUI, not the CLI. Thanks for the help.

• Switching To Ubuntu 14.04 from Windows 8.1

  - by Asangam

  everyone i am newto these linux stuffs. Currently i'm a user of Windows8.1 . When windows 8 was roling out i was like i'm never going to leave and will be always stick to windows8 but now i think it's time to switch linux because being in windows forever i don't think i can do something very good .I wanted to be OpenSource :) . So i really dont have any idea about linux . For me the best distro is Ubuntu and Kubuntu offcourse the latest release . So what i'm afraid of switching to linux is its compability .The compatibility i'm talking about is with the hardware's and driver's . For eg sometime after fresh install of windows we need to install the display,usb and wifi drivers to function . For some computer or brands those driver's are hard to find and i can't even think of linux how hard are they to find if it needs installing drivers. So my main question is that do i need to install the drivers for my wifi adapters display and some other stuffs or the distro i choosed i.e Ubuntu 14.0.4 consists of those dirvers and what about the 64 and 32bit . My machines is 64bit aso do i need to install the 64bit one . I mean i know the advantages of installing the 64 bit one but like windows is it kinda hard to find softwares for the 64 bit one . Or the 32 bit is recommended . And Yes I will be highly appreciated for the answers to my questions . Thank You :)

• Creating dynamic plots

  - by geoff92

  I'm completely new to web programming but I do have a programming background. I'd like to create a site that allows users to visit, enter some specifications into a form, submit the form, and then receive a graph. I have a few questions about this, only because I'm pretty ignorant: Is there a good framework I should start in? I know a lot of java, I'm okay with python, and I learned Ruby in the past. I figure I might use ruby on rails only because I hear of it so often and I think I've also heard it's easy. If anyone has some other recommendation, please suggest. The user will be entering data into a form. I'm guessing the request they'll be making should be one of a GET request, right? Because I don't intend for any of the data they're entering to modify my server (in fact, I don't intend on having a database). The data the user inputs will be used to perform calculations involving lots of matrices. I've written this functionality in python. If I use ruby on rails, should it be instead written in Ruby? Somewhere I've heard that you can either place the load of the work on your server or on the client's computer. Since the code performs heavy math, which option is preferable? How do I alter the setup to either make the client do the work or my server? Should I be using a "cgi-bin"? In the code that I have now, I use matplotlib, a python library, and then "show" the plot in order to see the graph. I specify the x and y limits, but I am able to "drag" the graph in order to see more data within the plot window. Ultimately, I want a graph to be shown on my site with the drag functionality. Is this possible? What if the client drags the graph so far, more computations must be made? Thanks!

• Not recognized as operating system on startup

  - by mastabruce

  I am new to Ubuntu and just decided to install it in (on my new lenovo thinkpad) in addition to my windows 7 operating system. Now, whenever I reboot the computer, it only runs window 7. I went (in windows) to Control Pannel ? System ? Advanced Settings ? Startup and Ubuntu is not even listed as a choice for operating system. I tried installing ubuntu again, but now it wants to partition the already partitioned windows folder. I can't figure out how to get Ubuntu, which seems to be installed, to run. I saw on another question here that I could be able to edit my mrb settings using EasyBCD but I can not figure out how to choose ubuntu as an operating system. My disk is already partitioned (seen from the attempted second install) so I'm pretty sure it is on the disk. Basically, how can I get ubuntu to run when I can't choose it as an operating system? Thank you for your help.

• Set one homepage for all browsers simultaneously

  - by MorganTiley

  For testing purposes, I would like to set the homepage of all browsers installed on my computer — Internet Explorer, Chrome, Firefox and Safari — to the same page. I'd like to do this all at the same time. I imagine that there's an application that has an input box for the URL I want to use as homepage and an OK button to set it in all browsers. Where can I get a utility or script that can do this?

• Browser keeps being really rude to me today

  - by j-t-s

  Hi All I've had this problem only once before, years ago. I bought a new computer the other day and last night I visited a website which Google Chrome suspected was an insecure site. So I proceeded to view the page anyway (Stupid, I know... But I was curious), and all of a sudden the window closed and ever since, every few minutes either Google chrome or Internet Explorer keeps popping up with random websites, most of which are porn-related sites. I have downloaded ZoneAlarm, IOBit 360, Eset Smart Security and none of them reported any problems. I still have the rube browser problem. Can somebody please suggest any software/ways to fix this? (Other than to reformat please :)) Thank you :)

• How to get headphones and speakers working at the same time?

  - by Borek

  I have a Gigabyte P55-UD3 motherboard which comes with a Realtek sound card and audio header for the front panel. My headset is permanently connected to the front panel (mic in, headphones in) and I also have speakers connected at the rear of the computer. What I want to achieve is that both the headphones and the speakers work at the same time. On my old PC with Realtek, I was able to do this by clicking "Device advanced settings" in the Realtek HD Audio Manager and then clicking "Make front and rear output devices playback two different audio streams simultaneously" and then doing some reassigning of front/rear settings in the Realtek Audio Manager (can't remember the details). But that doesn't seem to be working now - either the speakers play sounds or the headphones, not both at the same time. To pose the question differently, Windows plays the sounds on the "default device". I'd like to make both headphones and the speakers kind of like the default devices.

• Vertically resize two windows at same time?

  - by Guy

  I love the new feature in Windows 7 where I can grab the title bar and "slam" a window against the right edge of the computer and it will size that window to the right half of the screen. I can then grab another window and do the same against the left side of the screen. Once I've done that I often find that one of those windows needs a bit more horizontal space and the other can do with less. So I grab the edge in the middle of each window and resize that window so I can most efficiently use my screen space. Problem is that I have to do this twice, once for each window. Is there a way to grab the inside vertical edge of both windows at the same time so that I can make one wider and the other smaller at the same time?

• Memory works fine separately, but not together

  - by patersonjs

  I've been given four 1GB Corsair DDR2 memory modules, and am trying to fit them into my computer but am getting BSOD on Windows XP and errors in Memtest86+. I've tried to identify if one particular module is faulty by trying them in pairs. They work fine in pairs, but when all four are inserted, Memtest86+ reports errors. The motherboard is an Asus P5N-E with dual channel support and the modules are all the same model (same speed, capacity and timings) but one pair is a different hardware revision. One is v2.1 and the other is v2.2... the voltages are the same too. Would this minor difference be a possible cause of the problem? I've got the BIOS memory timing settings all at AUTO - should I manually set the timings?

• How to recover lost files after an install

  - by Gentry McColm

  I'm a newbie learning along the way. I recently installed a 2nd hdd into my ubuntu box. Have one of about 160g which runs ubuntu 12.04. And the new hdd was 1 tb, used for holding videos. I had set up 2nd drive as ext3 I believe. And set up folders on it to hold the videos. Worked great. Also thought I had set it up for auto mount. I was able to read and write on it. Etc. Computer froze, so had to reboot it. When I did, system would not reboot: hung on the Ubuntu screen with 5 dots. I hit a few buttons and the command screen showed up, indicating that my 2nd hdd would not mount. Stopped up whole system. Tried rebooting, no go. Had to reinstall ubuntu on the 1st hdd. Did not apparently touch the 2nd one. Well, when I got it up and running, my 2nd hdd mounted automatically (yeah!), but now I cannot find my videos I already had on it. I had not put any more than about 30g of videos on it, but now when I read its Properties, it says I'm using about 50g. So, I'm wondering if somewhere in that, buried, are my 17 videos. Any help in recovering this? Thanks!

• Tunneling through SSH for 1521 port access?

  - by A T

  I am developing locally on my computer, using my own Apache server with PHP configured. My database however is remotely located on an Oracle 11g Database Server. We were also given a separate remote server for hosting our .html and .php files, however only FTP access has been provided there. Development is far too slow waiting for the FTP connection to push. So I decided to develop locally, but still use the remote DB server. Unfortunately that gives me an error. Not sure how—or where—to integrate tunnelling. Do I add something to the oci_connect HOST in my PHP file, or do I encapsulate my whole environment over SSH?

• Is full partition encryption the only sure way to make Ubuntu safe from external access?

  - by fred.bear

  (By "external access", I mean eg. via a Live CD, or another OS on the same dual-boot machine) A friend wants to try Ubuntu. He's fed up with Vista grinding to a crawl (the kids? :), so he likes the "potential" security offered by Ubuntu, but because the computer will be multi-booting Ubuntu (primary) and 2 Vistas (one for him, if he ever needs it again, and the other one for the kids to screw up (again). However, he is concerned about any non-Ubuntu access to the Ubuntu partitions (and also to his Vista partition)... I believe TrueCrypt will do the job for his Vista, but I'd like to know what the best encryption system for Ubuntu is... If TrueCrypt works for Ubuntu, it may be the best option for him, as it would be the same look and feel for both. Ubuntu will be installed with 3 partitions; 1) root 2) home 3) swap.. Will Ubuntu's boot loader clash with TrueCrypt's encrypted partition? PS.. Is encryption a suitable solution?

• Wireless adapter won't enable

  I bought a d-link dwa-125, plugged it in and windows recognized it right away and said everything was good to go. But there were no connection options. When I open up the network control panel and have it show me the adapters... the wireless adapter is greyed out and says it is disabled. So I tell it to enable. It says is it enabling, then says it is enabled... but the adapter stayed greyed out saying disabled. I am running 7 x64. I have reinstalled drivers, connected it via lan and had it update drivers.. same problem. It works just fine on any other computer in the house, just not this one.

• Was Windows 95 an Operating System?

  - by shantnu

  This question maybe a bit historical, but we didn't have Superuser at the time. Around 2000 when I was starting my Computer science degree, a subject was Operating systems. The teacher asked us to list a few OS. I said Windows 95. I was immediately shot down. Windows 95 wasn't on OS, as it used DOS to boot up. The actual OS was DOS, Win 95 was just a graphical wrapper around it. I pointed that all trade magazines called Win95 an OS, but was told that they were run by laymen, and as a professional, I should know better. DOS was the only OS from Microsoft, at least till Win2K came out later that year. So 12 years on, I'm still not sure. Could Win 95 be considered an OS?
