  • Keyboard and touchpad do not work

    - by user289219
    I have an Lenovo IdeaPad S210 Touch and I want to install Ubuntu on it. The problem is that when I try booting the system from a USB drive (starting the so-called Live session) to try to see if the system works on my computer, the system will turn on and everything will work properly except for the keyboard and the touchpad. Neither of them are listed when using this command: xinput --list. I cannot get my laptop keyboard/touchpad to work, but USB keyboards and mice will work and my laptop's touchscreen will also work.

  • How can I backup files on /etc using Deja Dup? [closed]

    - by Chris Good
    Possible Duplicate: How do I open Deja Dup as root? I am using Ubuntu 12.04 LTS. I'm trying to setup Deja Dup to backup the files for several users (/home) and /etc but as it runs as myself, there are many files it cannot read and therefore cannot backup. I want to try running Deja Dup as root as then it should be able to read and backup all files. I've seen some other info about how to set up a particular App to run as root, so I guess I should try that.

  • Design for future changes or solve the problem at hand

    - by Naveen
    While writing the code or during design do you try to generalize the problem at the first instance itself or try to solve that very specific problem. I am asking this because, trying to generalize the problem tends to complicate the things (which may not be necessary) and on the otherhand it will be very difficult to extend the specific solution if there is a change in the requirement. I guess the solution is to find the middle path which is easier said than done. How do you tackle this type of problem ? If you start generalizing it at what point of time you know that this much of generalization is sufficient ?

  • Can I run Ubuntu Live from a USB flash-drive without destroying the data on it?

    - by Lucian
    I already have a number of files on a flash drive (8 gb) that I would prefer to keep, but I would like to try Ubuntu even if merely for the aesthetics. I use Windows XP. I know that it's definitely possible to run Ubuntu from a bootable drive like my flash drive to try Ubuntu but I would much rather keep my files intact not only on my flash drive but also my hard drive, if that's possible. I also want to know if it's entirely possible that while running Ubuntu from the USB if I can switch back to Windows while my computer is still on. If I'm missing something, please let me know. I'm very grateful for any assistance in this matter.

Any idea ?

  • XNA - Debugging/Testing Individual Sprites and Pixel Collision

    - by kwelch
    I ran through the first training on XNA where you make a shooter game. They did some thing that I would not do and I want to use their starting point to learn more things. I want to try better collision and adding a menu. I saw something online with the sonic physics where they have a frame by frame of sonic moving 1 pixel. See picture below. I am new to development, but I have been programming for years now. What would you guys suggest to try these different things out. How would I simulate a similar frame by frame testing as they do in the above picture? Thanks!

  • Find out if there is a local user logged in when logging in over ssh

    - by sebastiangeiger
    I need to run some calculations on a machine that I can only access remotely but also serves as a work station. There are many of them and I want to pick a "free" one. Free means in this case that no one is logged in locally. My first try was the who command, but for some reason it only lists "selected" users and I can't really find out how they are selected. Next try: ps aux | cut -d " " -f1 | sort | uniq: better showing a bunch of demons but also the local user that was not displayed by who. My current solution is to go in and do ps aux | grep "gnome-session" which is better but still gives me a lot of junk. Ideally I am looking for something that I can include in my ssh profile that warns me about (active) local users when I log in.

  • 11.04 64 bit live install cd freezes immediately on boot

    - by wrchis
    I am trying to install 11.04 alpha to a free set of partitions to try it out but neither the regular graphic installer or the alternate installer work. The graphic one freezes when I try to boot the cd (or cd image on usb stick rather) with a distorted static picture of my regular desktop repeated four times. I have an nvidia 240 graphics card if that is any help in diagnosis. I think it is a matter of getting the cd image to use a low rez video mode but I have no idea how to force that. I have used both the iso's from the regular page and the daily page (for several days so far) and they all do the same thing. I have tried both the internal utility and unetbootin to set up the stick with the same results. The alternate installer seems to work up to the point of the software selection step and then throws a 'failed step' error part way through.

  • Grub rescue problem after installing ubuntu

    - by Victor Suarez
    I have windows 7 installed in my internal hdd and wanted to try out Ubuntu so I got a USB to put Ubuntu LiveUSB on and installed Ubuntu on an external HDD and everything worked out fine. Now the problem. If I remove the external hdd and try to boot windows normally it shows the grub rescue screen. The only way to boot into windows is by having the external hdd attached. Is there any way I can make it so I wont have to have the external hdd attached to be able to boot my windows 7?

  • Travelling at Magenic

    - by Chris G. Williams
    I occasionally get asked if we travel "a lot" at Magenic. Sometimes the question comes from job candidates. Other times it's clients, recruiters or friends. To give a simple yes or no answer would be a disservice to the person asking the question. So here is my standard answer:It depends.(That was the short version.  Here's the long version...)We do have some guys that are more "national" in focus, and they can travel a fair amount. They also receive a little extra in compensation for doing so. It's a balancing act, and not necessarily a one-size-fits-all situation. Not everyone is well suited to constant travel. Some folks enjoy it and some folks hate it.With our local guys, our general policy is to TRY and keep them close to home whenever possible, but sometimes the needs of the client will dictate otherwise. (As Spock would say... the needs of the many outweigh the needs of the few, or the one.)In most cases though, we really do try to avoid sending our guys on extended travel gigs (i.e. every week for 6 months) when a simple kickoff trip and occasional visit will do. This depends on the nature of the gig, of course. Some types of work lend themselves to this model better than others. Additionally, this can and does vary by office. If one office is having trouble staffing a gig (not enough available bodies) and another office has a few too many folks on the bench, well... you can connect the dots. But again, we try to keep that to a minimum.Lastly, we all have our own thresholds for what we consider "a lot" of travel. There are two parts to this threshold:Half of it is whatever you're accustomed to already. The other half is being honest with yourself about how much you [like/hate] dealing with airports, car rentals, taxis, hotels, disruptions to your workout schedule, time away from friends/family, etc.Knowing a bit about yourself will definitely help you decide how much travel is too much for you.

  • Ubuntu 14.04 liveusb boot screen graphic errors

    - by user568109
    I am trying to install Ubuntu 14.04 on my Lenovo Y500 laptop. It came preinstalled with Windows 8. I want to install it in a separate partition with a USB drive. I have tried both Unetbootin and universal usb installer. But for some reason the screen after booting is crappy. The screen goes blank after selecting try ubuntu or install. If I try with nomodeset option the screen only displays on a small strip on the top. Which again is split into three. Each seem to be identical. It is not decent enough to begin installation. The graphic card in my laptop is Nvidia GT650M, if it helps. Maybe the problem is related to that. Can anyone help in fixing this error when installing Ubuntu.

  • Does the D programming language have a future?

    - by user32756
    I stumbled several times over D and really asked myself why it isn't more popular. D is a systems programming language. Its focus is on combining the power and high performance of C and C++ with the programmer productivity of modern languages like Ruby and Python. Special attention is given to the needs of quality assurance, documentation, management, portability and reliability. Do you think it has got a future? I really would like to try it but somehow the thought that I'm the only person on earth programming D discourages me to try it.

Yesterday I had it setup with login and password, but today when I try to get access to the server with: https://ubuntu:10000/ in order to login, I get unable to connect, the page does not load.

I am not sure of what it means to turn https on. ... the https and http is not showing. Am I going about this the wrong way?

  • Dealing with frustration when things don't work.

    - by John Isaacks
    You ever try to implement something simple but for some strange reason it doesn't work. So you try a possible solution but then something else doesn't work. You keep trying different workarounds but every time something different isn't working. Every time you get one step closer you also get one (or more) step farther from solving this problem and its now been 3 hours when this should have taken you 10 minutes. And it still isn't solved. There is no one in your company who can help, and you are about to put your fist through your screen. At this point you are so frustrated you can no longer think about the problem clearly. What should you do at this point? Or what can you do to avoid reaching this point?

  • How do you encourage yourself to program?

    - by Goma
    Imagine that you were given a studio or a room in 7-star hotel which is located by the sea, a luxury car and free massage service. All that were given on the condition that you should write your best code every day. You should come with new ideas and try and try again and again.. Will you accept that? Now come back to me please, the question is: what do you do to encourage youself to like programming and to write more of best practices and to come with new ideas? For example, if you were writing code and you get bored, in this case what do you do? Another example is, what do you do when some days are passed and you did not write anything? How do you recover and get back to work with high energy?

  • Gnome extensions don't work! I've tried everything!

    - by Nightshaxx
    When I go to https://extensions.gnome.org/, and try to install an extension, it clicks on, but nothing happens to my shell. Then, when I reload the page, the slider has turned off. Here are the things I have tried: I tried Chrome, Firefox, and Opera adding http://extensions.gnome.org to my allow plugin list in google chrome and made sure gnome-intigration is enabled I made a new firefox profile and tried installing it I reset my gnome shell settings (How do I reset GNOME to the defaults?) - this link actually broke my system, as now I can't log in to any desktop environment, the only way I can get to Unity, is by logging in to another desktop environment like cinnimon (which doesn't work) , then immediately logging into unity. Whenever I try to just log into unity or pretty much any other desktop environment, it logs in, but then seems to crash, and log out. Sometimes I even get quick glances of the Unity bar before it crashes I tried-re installing gnome None of these methods worked!! Thank you in advance!!

  • why client can not receive message from server (java) [migrated]

    - by user1745931
    I have just started learning java. I modified the client side code for a server/client communication program, by creating two threads for the client side, main thread for receiving user's input, and inputThread for receiving server's response. I am sure that server has sent the response to client, however, no response message is obtain at client. Here is my code. Can anyone help me to figure it out?
