  • How do I stop Ubuntu Precise freezing/hanging

    - by artfulrobot
    At least once a day I lose work on my (2 different) Intel i5 machines running Ubuntu 12.04. The entire system will freeze/lock-up/hang, and never return. At this point nothing works; even the caps lock key doesn't toggle the light on the keyboard; Ctrl-Alt-F1 won't do anything either. askubuntu.com is apparently where I'm directed for support. I suspect this is a kernel bug. But I simply can't keep losing work like this, so I'm anxious to try whatever it takes to get the thing reliably working. Can you suggest something I can try to fix the problem an existing bug I can follow progress on and contribute to (from users/tester's POV) the most constructive way I can contribute to helping fix the problem, keeping in mind that I do need the computer (so can't do things that might "brick" it!)

  • How to retrieve data from a corrupted volume

    - by explorex
    Hi, My Ubuntu 10.10 just crashed, probably due to hardware error (and in the end I was getting errors like Unknown filesystem ..... grub> .., and it went to the GRUB console before I could take any other action). I reinstalled the same version from a USB stick. I had Ubuntu installed with the ext4 file system and I also have the same filesystem in the same hard disk on a different drive. When I try to access my previous filesystem, I get errors: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda6, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so I had some important files in the previous volume ; I don't know how to retrieve them. And what are the chances that I would get the same outcome (hardware error)? Please help me!

  • 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.

  • Choppy video in Pitivi

    - by pedroo
    I am trying to edit 720p mov video footage in Pitivi, and when I place 1 clip in the timeline it plays fine in realtime. The problem begins when I add another clip and try to edit. Besides the 1st clip (that continues to run in realtime), all the other clips or cuts are choppy. I currently have 3gigs of ram and an Intel duo core processor. And using 10.10. Is there something I can try? I've heard of Kdenlive, is it better that Pitivi in handling 720p footage? Thank you very much!

  • Grub rescue after installing Ubuntu from USB

    - by Victor Suarez
    I have Windows 7 installed in my internal HDD and wanted to try out Ubuntu so I have an USB to put Ubuntu LiveUSB on and installed Ubuntu on a 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 won't have to have the external HDD attached to be able to boot my Windows 7?

  • Is AdWords ad blocked from top spots of SERPs until it is reviewed?

    - by Omeoe
    I have an AdWords ad and a keyword with a Quality Score of 10. Inferring from CPC from actual clicks, max CPC is set way beyond that of the third advertiser from the SERP for this keyword (there are three ads in the top). Still the ad is shown on the 4th spot which located either on the right or at the bottom of the SERP. The only catch is that the ad's status is "under review". Is it the reason why it's blocked from the top spots?

  • How do I airport-utils to configure my Airport Extreme?

    - by chands
    I'm trying to use this package (airport-utils) to try to configure my Airport Extreme. I was able to install it without a problem using apt-get but when I try to use it nothing happens. Literally, nothing: shreyas@shreyas-laptop:~$ airport2-portinspector shreyas@shreyas-laptop:~$ No windows open, nothing. I tried calling ps aux and grepping for anything that might hint to the command actually doing something but I came up empty. Does anyone have any experience with this package and can help me, or is there something else I can do to work with my Airport Extreme?

  • SQL Server v.Next (Denali) : Metadata enhancements

    - by AaronBertrand
    In my previous job, we had several cases where schema changes or incorrect developer assumptions in the middle tier or application logic would lead to type mismatches. We would have a stored procedure that returns a BIT column, but then change the procedure to have something like CASE WHEN <condition> THEN 1 ELSE 0 END. In this case SQL Server would return an INT as a catch-all, and if .NET was expecting a boolean, BOOM. Wouldn't it be nice if the application could check the result set of the...(read more)

  • 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.

  • 12.04 64 bit: Keybord not responding for about 20 seconds at startup/beginning of session

    - by Danilo
    I am running Ubuntu 12.04 64bit. When I get at the login screen and try to type the password for my user, I cannot type anything for about 20 seconds. After that, the keyboard starts responding and everything works fine. Mouse is responding normally as well as all buttons of the login interface (time/calendar, session selection (Unity/Unity 2D), etc.). What could be the reason for this behavior? How can I solve this temporary freeze of the keyboard so that I can type my password immediately without having to wait each time? Thanks for your time. EDIT: I tried auto login, but the problem is still there: the Desktop loads but even there, if I try to type something in the dash or anywhere else, I must wait about 20 seconds before I can actually start typing. Can the issue be related to some keyboard modules that get loaded little bit "too late"?

  • System doesn't boot when ubuntu is installed on an SSD

    - by Caetano Nichnich Nunes
    I've recently discovered Ubuntu and decided to give it a try. I am using a Samsung Series 5 p530u3c-ad1 which comes with a 24gb SSD and a ~500gb HDD, My intention is to set the system files to the ssd and the rest to the HDD. The system works fine if I do a direct install using only the HDD, but if I try using the SSD for the system files the computer doesn't boot-up, I do not know if the SSD is being recognized by the computer, I think so because I could install Ubuntu on it, but it doesn't appear on the boot order or the boot menu. I read some posts and tried using boot-repair which pointed me not to forget to set my system to boot from my SSD, unfortunately I cannot because of the issues mentioned above. Thanks for your time.

  • bluetooth on acer travelmate laptop can send only, but don't want to receive

    - by Orosjopie
    I have a acer travelmate 5720 laptop that runs ubuntu 13.04. It has built in bluetooth. For what I can see is that Ubuntu did pick up the bluetooth and the necessary bluetooth drivers is installed. But I'm only able to send files from this laptop to bluetooth devices, but for some reason I can't do the same visa verso to the laptop, for example if I try to send a file from a blackberry 9360 it can't send, tells me failed to find service. It kicks out. I try to find more drivers to install, tried a few in ubuntu software center, but no success. I even uninstalled all bluetooth drivers and reinstalled it, but no success, it doesn't pick up any phone anymore. Please assist me.

  • flashplugin installer works for firefox but not chromium-browser

    - by user829755
    I'm on Ubuntu precise (12.04.5 LTS) and I do have flashplugin-installer installed. When I click on flash videos in chromium-browser I get "An error occurred, please try again later". In firefox they display fine. I opened chrome://plugins to see if the flash plugin is installed and indeed it's not listed. Also http://www.codegeek.net/flash-version.php displays: "You do not have Flash player installed", while with firefox it says: You have Flash player 11.2.202 installed. Following some instructions on some ubuntu page I copied the plugin using sudo cp /usr/lib/flashplugin-installer/libflashplayer.so /usr/lib/chromium-browser/plugins/ and I started chromium using chromium-browser --enable-plugins but this didn't help. chrome://chrome/ says: Version 36.0.1985.125 Ubuntu 12.04 (283153). what else can I try?

  • OOF checklist

    - by Daniel Moth
    When going on vacation or otherwise being out of office (known as OOF in Microsoft), it is polite and professional that our absence creates the minimum disruption possible to the rest of the business, and especially our colleagues. Below is my OOF checklist - I try to do these as soon as I know I'll be OOF, rather than leave it for the night before. Let the relevant folks on the team know the planned dates of absence and check if anybody was expecting something from you during that timeframe. Reset expectations with them, and as applicable try to find another owner for individual activities that cannot wait. Go through your calendar for the OOF period and decline every meeting occurrence so the owner of the meeting knows that you won't be attending (similar to my post about responding to invites). If it is your meeting cancel it so that people don’t turn up without the meeting organizer being there. Do this even for meetings were the folks should know due to step #1. Over-communicating is a good thing here and keeps calendars all around up to date. Enter your OOF dates in whatever tool your company uses. Typically that is the notification to your manager. In your Outlook calendar, create a local Appointment (don't invite anyone) for the date range (All day event) setting the "Show As" dropdown to "Out of Office". This way, people won’t try to schedule meetings with you on that day. If you use Lync, set the status to "Off Work" for that period. If you won't be responding to email (which when on your vacation you definitely shouldn't) then in Outlook setup "Automatic Replies (Out of Office)" for that period. This way people won’t think you are rude when not replying to their emails. In your OOF message point to an alias (ideally of many people) as a fallback for urgent queries. If you want to proactively notify individuals of your OOFage then schedule and send a multi-day meeting request for the entire period. Remember to set the "Show As" to "Free" (so their calendar doesn’t show busy/oof to others), set the "Reminder" to "None" (so they don’t get a reminder about it), set "Low Importance", and uncheck both "Response Options" so if they don't want this on their calendar, it is just one click for them to get rid of it. Aside: I have another post with advice on sending invites. If you care about people who would not observe the above but could drop by your office, stick a physical OOF note at your office door or chair/monitor or desk. Have I missed any? Comments about this post by Daniel Moth welcome at the original blog.

  • Can't install wireless driver or get ubuntu to recognize ethernet cable

  • Mobile phone detection (brand, model, browser etc)

    - by SyaZ
    What do you use to detect visitor's mobile phone, down to the model if possible? Currently we maintain our own database but it's really getting behind due to lack of manpower to maintain it, so we decided to give 3rd party solution a try. These are my candidates but I don't have time to really try them all: DeviceAtlas - 1 year personal evaluation, but basic license is affordable. Their database look solid with daily update and user-contributed tests / updates. I am favoring this one at the moment. DetectRight - I was recommended this by a colleague but really can't find much from their site. 20k devices -- really? WURFL - Open source, database collaboratively derived from UAProf. So basically if you're going with UAProf solution, you're better off with WURFL. DetectMoBileBrowsers - This looks like the simplest of all. Too bad it's language dependent (PHP). Please share your experience or suggestions!

  • 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!

  • Are Languages pretty much "stable" for now?

    - by Sauron
    Pardon the odd question, but I looked recently at a sort of "timeline" of Programming Languages and while alot has changed in the past 5-10 years and what has grown, there are alot of languages that have pretty much "stayed" the same in their same niche/use. Like for Example C.....we don't really ever see much languages being developed (Correct me if im wrong) to try to Unseat C, however there are alot of languages that try to do Similar things (Look at all the SQL/No-SQL languages) Scripting Languages, etc... Is there a reason for this? Or is it just because C does what C does so well.....that there isn't really a need?

  • Netbook partitioning scheme suggestions

    - by David B
    I got a new Asus EEE PC 1015PEM with 2GB RAM and a 250GB HD. After playing with the netbook edition a little, I would like to install the desktop edition I'm used to. In addition to ubunto partition(s), I would like to have one separate partition for data (documents, music, etc.), so I could try other OSs in the future without losing the data. What partition scheme would you recommend? I usually like to let the installation do it by itself, but when I try to that I can only use the entire disk, so I don't get the desired data partition. I wish there was a way to see the recommended default partitioning scheme, then just tweak it a bit to fit your needs (instead of building one from scratch). So, how would you recommend I partition my HD? Please be specific since I never manually partitioned before. Thanks!

  • Uploading or attaching files that located on a shared drive doesn't work?

    - by Alex
    I have this odd, quite minor, but annoying issue that I am quite perplexed about. Whenever I try to upload a file via my browser(let's say attach a file to an email in GMail), I click 'Browse' button and it opens standard file selection dialog, that doesn't show network drives. Further more if I try to drag a file from a network drive into GMail, it doesn't work either, it just doesn't let me do that. This issue has been around for quite sometime now, and I am just curious if this is something on my side or if it's a bug or a misconfiguration of some sort. FWIW, I am currently running 10.10, network drive is a samba share on NAS. This happens in FF and Chrome and this is only happens with Samba mounts. As a matter of fact, NFS volumes that are located on the same network operate perfectly fine.

  • Uncontrolled Fan and Crash

    - by RobotbeatsHuman
    I don't have sensors to properly run lm-sensors. The computer will turn on but shortly there after all the fans in it will speed way up. It stays like this for a few minutes and then the computer shuts off. Tried resetting the BIO. Went to try installing a BIOs update but it wont stay on long enough for me to try that or to do a clean install. Could this be the motherboard dying? It's mainly the CPU fan that ends up going max. after a few minutes. I checked the PSU and It's a Dell Inspiron 580. If you need more system specs just le me know.
