  • Audio Problems with my Mac running Ubuntu 12.04

    - by Tomtom
    I've got a mac (desktop around 2008). I installed Ubuntu 11.10, then remembered I had 12.04 on a disc. I installed 12.04 and now the audio will not work. I've tried all the killallpulse and looked briefly at the Alsa thing. I put in speakers and they only work with the headphone setting. When i put in cat /proc/asound/cards I get: 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0x50600000 irq 47 I do have the Mac startup noise but no sound in Ubuntu

  • Save inkscape figure in 400dpi (png or jpeg)

    - by user68624
    I'm a difficulty in Ubuntu. I need to save a figure work of Inkscape in png or jpeg format, however, this figure work needs to be 400dpi resolution. I saved the jpeg using output pro inkscape plugin, but I can not insert the image into LibreOffice Writter (I think the reason is that the image was very extensive, but I am obliged to do so, because my university has the using standard figures 400dpi). Could anyone help me? Thank you!

  • When will the Unity Greeter begin to look like the propositions from the Design Team?

    - by Marcappuccino
    The Canonical Design Team gave a rather beautiful login screen mockup for the unity greeter. These designs, in my opinion far exceed the current UI that we have for Quantal (which I think is worse, apart from remote login), and I was led to beleive that these were the official guidelines for the greeter. Are there plans to implement these designs into the Unity Greeter? The proposal is here: https://docs.google.com/a/canonical.com/document/d/1ypvxcSmwNKKMZawit-0r6uLnbTxoA-XoyB0ZNCKNMSg/edit?pli=1 The mockups are here: https://docs.google.com/a/canonical.com/file/d/0BzP7juF4TDpQS3JCWmtHTmR6OVk/edit?pli=1

  • git workflow for separating commits

    - by gman
    Best practices with git (or any VCS for that matter) is supposed to be to have each commit do the smallest change possible. But, that doesn't match how I work at all. For example I recently I needed to add some code that checked if the version of a plugin to my system matched the versions the system supports. If not print a warning that the plugin probably requires a newer version of the system. While writing that code I decided I wanted the warnings to be colorized. I already had code that colorized error message so I edited that code. That code was in the startup module of one entry to the system. The plugin checking code was in another path that didn't use that entry point so I moved the colorization code into a separate module so both entry points could use it. On top of that, in order to test my plugin checking code works I need to go edit UI/UX code to make sure it tells the user "You need to upgrade". When all is said and done I've edited 10 files, changed dependencies, the 2 entry points are now both dependant on the colorization code, etc etc. Being lazy I'd probably just git add . && git commit -a the whole thing. Spending 10-15 minutes trying to manipulate all those changes into 3 to 6 smaller commits seems frustrating which brings up the question Are there workflows that work for you or that make this process easier? I don't think I can some how magically always modify stuff in the perfect order since I don't know that order until after I start modifying and seeing what comes up. I know I can git add --interactive etc but it seems, at least for me, kind of hard to know what I'm grabbing exactly the correct changes so that each commit is actually going to work. Also, since the changes are sitting in the current directory it doesn't seem like it would be easy to run tests on each commit to make sure it's going to work short of stashing all the changes. And then, if it were to stash and then run the tests, if I missed a few lines or accidentally added a few too many lines I have no idea how I'd easily recover from that. (as in either grab the missing lines from the stash and then put the rest back or take the few extra lines I shouldn't have grabbed and shove them into the stash for the next commit. Thoughts? Suggestions? PS: I hope this is an appropriate question. The help says development methodologies and processes

  • Mouse and keyboard not working after upgrading to 11.10

    - by geeehhdaa
    After upgrading to Ubuntu 11.10, neither my keyboard nor my mouse work anymore. The keyboard works during the boot process, but stops working as soon as the login screen appears. I'm stuck there because without a mouse or a keyboard I can't login or start a shell. If I hit ESC during startup to make the grub manager appear, the manager appears, but the keyboard won't work anymore. Mouse: Logitech RX 250, Keyboard: Cherry RS 6000

  • Help recovering broken OS (permissions issue)

    - by Guandalino
    (At the bottom there is an important update.) I was doing experiments in order to backup a remote account to my local system, Ubuntu 12.04 LTS. I'm not confident with duplicity and probably, due to wrong syntax, some local files have been replaced with remote files. This is just a supposition, I'm not sure this is the real cause of OS corruption. The corruption happened after experimenting with backups, so I think I did something wrong at this regard. I was aware there was a problem when I tried to access a command using sudo: $ sudo ls sudo: unable to open /etc/sudoers: Permission denied sudo: no valid sudoers sources found, quitting sudo: unable to initialize policy plugin This is how /etc/sudoers looks like: $ ls -ald /etc/sudoers -r--r----- 1 root root 788 Oct 2 18:30 /etc/sudoers At this point I tried to reboot and now this is the message I get: The system is running in low graphics mode. Your screen, graphics card and input device settings could not be detected correctly. You will need to configure these yourself. I tried to follow the wizard to configure these settings, but without luck (the system prevents me going on when I press "Next"). The thing that makes me a bit less worried is that all the data on the disk seems readable and I'm able to access them using a live cd. I run memtest and RAM seems to be OK. Do you have any idea about how to recover my system? I'm very glad to provide further information, just let me know what info could be helpful. UPDATE. The issue is about wrong permissions and this is how I discovered: I mounted the root partition of the broken OS on /mnt/broken/ (live CD) and did ls /mnt/broken/. I got a permission denied error, while I expected to have the directory listing. I had to do sudo ls /mnt/broken/ and this worked. Thus without having root permission via sudo it's impossible to access the root of broken os. The current output of ls -ld /mnt/broken/ is: drwxr-x--- 29 1000 812 4096 2012-12-08 21:58 /mnt/broken Any thoughts on how to restore the old (working) set of permissions?

  • how to install oracle 10g xe on ubuntu 11.04

    - by ses
    I have read from here how to install oracle 10g xe in ubuntu 10.x but not in 11.04 (64 bit). But with 11.04 it does not work anymore because of dependency exceptions. So, how to install oracle 10g xe in ubuntu 11.04? I even found some variant how to fix it from here but in my case it does not work - the same exception take place: oracle-xe-universal:i386 depends on libc6 (= 2.3.2); however: Package libc6:i386 is not installed.

  • How do you completely reset monitor configuration (e.g. what used to be dpkg-reconfigure xserver-xorg)?

    - by John
    Using unity 11.04. I have a secondary monitor (actually two, one at home, one at work). The home twin monitor set up works perfect (Viewsonic monitor). At work, I get very buggy behaviour, such as full screen applications 'ghosting' when maximized, and other strange effects. I would like to try and completely reset the monitor configurations (not unity or compiz), before doing anything else. In 10.10 this would be accomplished: dpkg-reconfigure xserver-xorg

  • is it possible to ssh into ubuntu server with keys and from another computer using password?

    - by Sandro Dzneladze
    I have ubuntu server at home, and I use SSH keys to log in via terminal from my laptop. Rarely, but mostly from work, I need to access this server, but I dont want to copy keys on my work laptop - Id rather just use plain password for that. So if I enable password log in from ssh config file, it will ask me password on my laptop too even though it contains keys, right? Is there a way to stop this behavior? Thanks.

  • What's a good way to get an IT internship? [closed]

    - by user1419715
    I'm a second year CS student who's worked really hard to build and expand my skills. I've spent the past week now trying to find a place to volunteer (i.e. work for FREE) so I can get a little bit of in-the-door experience with web development. I have a portfolio with several decent projects, a handful of languages and other hard/soft skills that employers constantly say they're clamoring for. I can't even get people to take my calls. This is me offering to work for them for FREE, remember. I'm in a reputable program at a respected school, get decent grades and...yeah, I've worked really hard to be presentable. On the rare occassions I actually get to speak to somebody at a design firm they hedge and do everything they can to get me off the phone. Nobody's ever expressed even the slightest interest in taking me on. The answer to the experience problem is supposed to be "you need to spend a year or two building up a big portfolio of projects on your own" so that employers will be impressed. I've done that. Websites, standalone apps, etc.. Nobody will even look at my resume, though. Question: Why does there seem to be so little interest in taking on upaid interns in the world of IT? Update: Sorry you all think I'm too aggressive or angry. It wasn't my intent to be a jerk to people while asking them for their opinions. That said, how would you feel if employer after employer turned you down cold when you offered yourself to them without asking for remuneration? One can't even get an unpaid job in this economy now, it seems. How am I going about my search? I find web firms in my area and contact them via email with a brief sales pitch of myself and a resume attached. Then a couple of days later I follow up with a phone contact. Nobody--anywhere--is advertising for interns of any kind. If there were I'm sure there'd be about 500 resumes per position, even unpaid. I've had good experiences in the past with cold-calling firms for actual paid jobs in other industries (hiring is a pain in the ass process and a call like this can show initiative while reducing a busy employer's need to do all the hiring overhead work), so I thought volunteering would work at least as well. My skills are pretty good for a CS student and include the usual suspects: HTML/CSS/Javascript, Python, Java, C, C#/.Net etc etc. I made a point on my resume to tie each ability claim to a project as well. Oh, and regarding the "working for free still costs the employer money" argument: that's an excellent point I hadn't though of. But it means...what? I have to pay the employer for the privilege of working there now?

  • Can't install Dual Boot from USB live - crash and nouvea problem

    I just got a new laptop with Windows 8 pre-installed and I'm trying to make a dual boot with Ubuntu on my other hard drive but I can't make the Live USB work. I followed all the procedure for disabling the Security Boot and the UEFI setting but still doesn't work. It seems to start the installing procedure but I never get to choose anything: after a few seconds the screen turns black with an error message [18.707838] divide error: 0000 [#1] SMP (it goes on for several lines quoting some nouveau problem). Any ideas?

  • Is there an equivalent of jsqlparser but for SPARQL instead of SQL?

    - by Programmer
    I'm trying to use Java to construct a SPARQL query, and then send it off to a remote database. However, I'm new to both Java and SPARQL, so I was wondering if anyone could explain how to do this, rather than just posting a link. I heard there is a tool called jsqlparser for the same task, except that it's for a SQL to SPARQL conversion using Java. Conversion nor parser won't be necessary, just a method for constructing a query and querying the database provided by the user.

    I currently have a full time job as a Microsoft.NET developer, but I'd like to supplement my income by doing some part-time freelance development work. Are there any websites (or other sources) out there that specialize in this? While the website (or other source) does not have to be geared specifically for part-time work or Microsoft.NET development, if it is than that would be just wonderful. The only thing I could find close to this was www.vworker.com which is not that great.

  • Should the main game object be static in c++

    - by Som_kun
    I am creating a 2d platformer using SDL and I was thinking that my game object could be static, but I wasn't sure if this was a good idea. The pros (that I can see): Accessing settings options (such as screen size and keyboard bindings) would be easier accessed There should only ever be one main game loop, so this makes sure for me. The cons: From what I've heard, static classes in C++ are a bear to work with I've read that this may cause problems later in development (things don't work right or can't be used properly
