  • I can't get suspend, hibernate and shutdown to work in Ubuntu 12.04

    - by Fostext
    I recently built a computer with these specs: Asus Motherboard, Intel i3 3.3 GHz dual processor, 8 GB of RAM. I installed 12.04 on a brand new hard drive. I partitioned the hard drive between root, home and swap like I have often read how to do. I cannot get this machine to properly shutdown. I have to hold the power button down now. Although, for the first few days it properly shutdown. I also cannot get the system to hibernate or suspend properly. I have read tons on this and watched many YouTube tutorials on how to fix both, but the computer never wakes up after suspend or hibernate. It just stays on a black screen. Can anyone help? I love 12.04 so far, but these setbacks are making me worried about stability and power management issues. Also, I wonder if it's really bad for the hard drive to force the CPU to shutdown.

  • Ubuntu install and dual Boot with Windows 8 UEFI

    - by Jose Maria
    i have Ubuntu 12.04 x64 ISO, i load it on a Fat32 USB. My notebook has a hdd with GPT where i installed Official Win 8 Pro x64 (final versión), I partitioned the whole hdd, previously of win 8 install, and bios is set with UEFI boot. My BIOS notebook doesn't support SECURE UEFI BOOT. So I boot the notebook from USB and the Grub runs OK showing whether to run Ubuntu live or to install, but neither one neither two works, when I choose then the screen shows black and nothing happen, it doesn't start/loads the install program. I've try whether to prepare the usb with unetbootin, or just direct copy/paste the files onto the USB. I also have try WUBI, but neither with success, it launch an error when ending.

  • Timeout when trying to install ubuntu 12.04

    - by Oskars
    When i click on "try ubuntu" after booting it from a USB the screen goes black and a lot of text comes out. But after a while it says "timeout: killing /blablabalba" or something like and it just keep on saying that. What have I done wrong? <.< My computer is a Acer ASPIRE M5201 if that is of any importance. Edit: I noticed now that before it says "timeout" it says something about not supporting "DNS" or "Asn" or something like that. I'm not sure if it was exactly dns and asn but do this mean that I can't run ubuntu on this computer? Edit2: The exact strings are: "[sdg] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA " "timeout: killing '/sbin/modprobe -bv pci:v00001002d00"(and more nubmers wich I didn't catch)

  • Why don't Normal maps in tangent space have a single blue color?

    - by seahorse
    Normal maps are predominantly blue in color because the z component maps to Blue and since normals point out of the surface in the z direction we see Blue as the predominant component. If the above is true then why are normal maps just of one color i.e. blue and they should not be having any other shades(not even shades of blue) Since by definition tangent space is perpendicular to normal at any point we should have the normal always pointing in the Z (Blue direction) with no X(Red component) and Y(Green component). Thus the normal map(since it is a "normal map") should have had color of normals which is just the Blue(Z =Blue compoennt = 1, R=0, G=0) and the normal map should have been of only Blue color with no shades in between. But even then normal maps are not so, and they have gradients of shades in them, why is this so?

  • Can't see my partitions after grub recovery

    - by dimbo
    I stupidly inserted the windows CD into my dual boot Ubuntu 11.10 / windows xp system. I just wanted to see if I could install windows on my external usb HD, but didn't actually go ahead with the install. It seems like the windows CD messed up my MBR and I had to use boot-repair and the ubuntu 11.10 live CD to gain access to ubuntu again. It seems to boot up a little differently (slower) but works. However, I now cant see any of my partitions in nautilus (there are 3). When I open gparted, it just shows my whole hard drive as unallocated (I know it has a windows partition that works and my ubuntu partition that I am using now). If I insert a usb pen, it is also not visible in nautilus but in gparted shows up as a FAT32 partition (which is correct although I cannot access it). sudo fdisk -l gives the following : demian@dimbo-TP:~$ sudo fdisk -l [sudo] password for demian: omitting empty partition (5) Disk /dev/sda: 320.1 GB, 320072933376 bytes 240 heads, 63 sectors/track, 41345 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x877b877b Device Boot Start End Blocks Id System /dev/sda1 * 63 63842309 31921123+ 7 HPFS/NTFS/exFAT /dev/sda2 63844350 133484084 34819867+ 5 Extended /dev/sda3 127636488 133484084 2923798+ 82 Linux swap / Solaris /dev/sda4 133484085 625137344 245826630 83 Linux /dev/sda5 63844352 123445247 29800448 83 Linux /dev/sda6 123447296 127635455 2094080 82 Linux swap / Solaris Disk /dev/sdb: 8100 MB, 8100249600 bytes 12 heads, 40 sectors/track, 32960 cylinders, total 15820800 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc3072e18 Device Boot Start End Blocks Id System /dev/sdb1 * 5992 15820799 7907404 c W95 FAT32 (LBA) Here is my grub.conf file.

  • Ubuntu won't run

    - by Cody
    So I just installed it last night, the latest version. I did a fresh install. When I woke this morning I turn on the computer and login. It goes to a black screen with two thick with/multicolored lines towards the bottom and freezes. I then must shut down the tower. I have only been able to run the 'Ubuntu 2D' option. I am new to this all and need some help. Also when I am using terminal it wants me to enter my password, but it says its incorrect. Is there anyway so I don't need to enter my password when I use it and also when I install or remove something? Many thanks would be helpful. What is Ubuntu 2D?

  • My site is getting popular, bandwidth expensive

    - by ElbertF
    I'm running a (small) image hosting site which has been getting a little bit of traction lately (2,000 to 5,000 visitors a day, spikes up to 10,000). It's hosted on Linode and I've already run out of the bandwidth for this month (300 GB). I've experimented with Amazon S3 but that was costing me $5 a day, Linode currently costs me $30 a month. I get a tiny bit of revenue from ads (Adsense and Black Label Ads) but it's not enough to break even. What should I do? Obviously I'd like to keep running the site but not if it starts costing me a lot of money.

  • After upgrade from 10.10 to 11.04 Ubuntu doesn't load the splash screen anymore

    - by Vincent Vega
    I have the problem that Ubuntu doesn't load the splash screen anymore (after upgrading from 10.10 to 11.04). After the Grub-bootloader, it takes a few seconds to load and then the monitor turns black. I already tried to boot from a Ubuntu Live CD, but the result was the same error. Furthermore I tried to start the protected mode, but it freezes just after showing me menu. Do you have any solutions for this? And is it possible to switch from Grub to the Ubuntu console?

  • Why are the packages found with apt-get always horribly out of date?

    - by Andrew
    Whenever I use the package manager, it can only ever find really old versions of stuff. Example: sudo apt-get update sudo apt-get install postgresql The best it can do is version 8.4 (3 years out of date). Trying to get a later version, I get: $ sudo apt-get install postgresql-9.1 Reading package lists... Done Building dependency tree Reading state information... Done E: Couldn't find package postgresql-9.1 I experience the same issue whenever I use the package manager, so I usually just download and build things from source. How can I make it find up-to-date software?

  • Does using structure data semantic LocalBusiness schema markup work for local EMD URL's?

    - by ElHaix
    Based on what I have read about Google's recent Panda and Penguin updates, I'm getting the impression that using semantic markup may help improve SEO results. On a EMD (exact match domain) site, that may have been hit, we list location-based products. We are now going to be adding a itemtype="http://schema.org/Product" to each product, with relevant details. However, that product may be available in Los Angeles and also in appear in a Seattle results page. We could add a LocalBusiness item type on each geo page to define the geo location for that page. While the definition states: A particular physical business or branch of an organization. Examples of LocalBusiness include a restaurant, a particular branch of a restaurant chain, a branch of a bank, a medical practice, a club, a bowling alley, etc. We could add use the location property which would simply include the city/state details. I realize that this looks like it is meant for a physical location, however could this be done without seeming black-hat?

  • Agile Testing Days 2012 – My First Conference!

    - by Chris George
    I’d like to give you a bit of background first… so please bear with me! In 1996, whilst studying for my final year of my degree, I applied for a job as a C++ Developer at a small software house in Hertfordshire  After bodging up the technical part of the interview I didn’t get the job, but was offered a position as a QA Engineer instead. The role sounded intriguing and the pay was pretty good so in the absence of anything else I took it. Here began my career in the world of software testing! Back then, testing/QA was often an afterthought, something that was bolted on to the development process and very much a second class citizen. Test automation was rare, and tools were basic or non-existent! The internet was just starting to take off, and whilst there might have been testing communities and resources, we were certainly not exposed to any of them. After 8 years I moved to another small company, and again didn’t find myself exposed to any of the changes that were happening in the industry. It wasn’t until I joined Red Gate in 2008 that my view of testing and software development as a whole started to expand. But it took a further 4 years for my view of testing to be totally blown open, and so the story really begins… In May 2012 I was fortunate to land the role of Head of Test Engineering. Soon after, I received an email with details for the “Agile Testi However, in my new role, I decided that it was time to bite the bullet and at least go to one conference. Perhaps I could get some new ideas to supplement and support some of the ideas I already had.ng Days” conference in Potsdam, Germany. I looked over the suggested programme and some of the talks peeked my interest. For numerous reasons I’d shied away from attending conferences in the past, one of the main ones being that I didn’t see much benefit in attending loads of talks when I could just read about stuff like that on the internet. So, on the 18th November 2012, myself and three other Red Gaters boarded a plane at Heathrow bound for Potsdam, Germany to attend Agile Testing Days 2012. Tutorial Day – “Software Testing Reloaded” We chose to do the tutorials on the 19th, I chose the one titled “Software Testing Reloaded – So you wanna actually DO something? We’ve got just the workshop for you. Now with even less powerpoint!”. With such a concise and serious title I just had to see what it was about! I nervously entered the room to be greeted by tables, chairs etc all over the place, not set out and frankly in one hell of a mess! There were a few people in there playing a game with dice. Okaaaay… this is going to be a long day! Actually the dice game was an exercise in deduction and simplification… I found it very interesting and is certainly something I’ll be using at work as a training exercise! (I won’t explain the game here cause I don’t want to let the cat out of the bag…) The tutorial consisted of several games, exploring different aspects of testing. They were all practical yet required a fair amount of thin king. Matt Heusser and Pete Walen were running the tutorial, and presented it in a very relaxed and light-hearted manner. It was really my first experience of working in small teams with testers from very different backgrounds, and it was really enjoyable. Matt & Pete were very approachable and offered advice where required whilst still making you work for the answers! One of the tasks was to devise several strategies for testing some electronic dice. The premise was that a Vegas casino wanted to use the dice to appeal to the twenty-somethings interested in tech, but needed assurance that they were as reliable and random as traditional dice. This was a very interesting and challenging exercise that forced us to challenge various assumptions, determine/clarify requirements but most of all it was frustrating because the dice made a very very irritating beeping noise. Multiple that by at least 12 dice and I was dreaming about them all that night!! Some of the main takeaways that were brilliantly demonstrated through the games were not to make assumptions, challenge requirements, and have fun testing! The tutorial lasted the whole day, but to be honest the day went very quickly! My introduction into the conference experience started very well indeed, and I would talk to both Matt and Pete several times during the 4 days. Days 1,2 & 3 will be coming soon…

  • Can not get to login screen, background starts with terminal prompt only

    - by Doug
    my uncle has Ubuntu on his work PC. Basically I came in to work today, and he had lost his UNITY side bar. I told him start with just rebooting it. He rebooted it... now it does not even get to the login screen. It gets to the background with the word UBUNTU, and the 6 or 7 dots, does it's little loading dot thing... then stops, and a black terminal opens on the top left with the background still in place. Personally, I think he screwed it up himself. He always swears he didn't touch anything, but I know better... Either way, I can't get him back into the desktop to even see if the sidebar is back. He's always screwing around pressing the wrong buttons on the login screen, hitting admin things and such... Any ideas?

  • My computer will no longer suspend or shut off when I close the lid

    - by dave
    This is somewhat annoying. I have an old laptop and the screen on it is shot, so now I have an old monitor hooked up and it works fine. Before the upgrade I had it set so that when i closed the lid on the laptop everything would shutdown or suspend, when I lift the lid, everything would come back. Now, however, when i close the lid nothing happens, when i open the lid the screen flashes black and comes back. I have it set so that it should suspend when i close the lid. It's confusing...

  • Getting "boot error" when trying to boot from USB

    - by Jon Ball
    I'm wanting to try out Ubuntu, so followed the instructions for how to install Ubuntu onto a USB. I downloaded the .iso file, then the pendrivelinux 3 part process to make the USB bootable. I can see what looks like a full list of files on the USB (including the wubi.exe application and the syslinux folder). When I try to restart the computer with the USB in, I get the Dell start up screen, and then a black screen with "Boot Error" in the top right hand corner. Setup options (default) are to boot from Removable Device, then Hard Disc. USB is brand new, straight out of the packet. Computer: Dell Inspiron 530S BIOS: 1.0.13 OS: Windows Vista Home Edition USB: EMTEC 8Gb, formatted to FAT32 I've tried some of the tips in other help topics (holding down CTRL key while restarting, removing all other USB devices). I tried to reformat the USB to something other than FAT32, but my only other options were NTFS or exFAT (not FAT16 which was suggested in another topic).

  • Which ATI driver version did 10.04 use?

    - by Jack
    I have a trouble with ATI driver with Ubuntu 12.04 LTS. When I install ATI driver in Ubuntu 12.04 via "Additional Driver", then I can't shutdown Ubuntu, it showed blank (black) screen and my laptop still run. Sometimes, my screen like that: http://www.youtube.com/watch?v=U9_iygesbBM But when I install Ubuntu 10.04 and install ATI driver via "Additional Driver", it's very good and no trouble I've seen. It's sweet but 10.04 is old and is supported to 4/2013. So I want to know why Ubuntu 10.04 works good better than 12.04 with ATI driver (in my case)?

    - by Khaled Musleh
    my laptop Toshiba Qosmio G30 has nVidia GeForce Go 7600 card and it suppose to support 3D . i run unity 2d now . I run 12.04 and the graphic driver is--VESA: G73 Board - toshg73m-- by UBUNTU. when i run /usr/lib/nux/unity_support_test -p then i get this list Not software rendered: no Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no the card is not blacklisted but a similar one with GT is! Do you think that there is a chance the laptop can run the unity 3d? and may be i could change the resolution of the screen to a higher one too! I tried all the nvidia drivers provided but none works (except 96 in ubuntu 12.04 ). i get a black screen or terminal screen. best wishes to all
