  • HDMI port not recognized on Sony Vaio

    - by julio
    I am running Ubuntu 11.10 64bit with a Sony VAIO VPC F11. It has an NVIDIA GeForce 310M video card, with the latest Nvidia drivers for the 64 bit linux, and a Windows partition with Win7 64bit. NVIDIA driver version is NVIDIA-Linux-x86_64-280.13 External monitor is Samsung SyncMaster P2770 If I boot into the Windows partition, the HDMI works as expected, with sound and video-- under linux, the HDMI port is not recognized at all, apparently, and provides no signal to the attached monitor. The nividia-settings tool does not recognize any monitor connected to the HDMI port. Disper is installed and cannot recognize an attached external monitor. Can anyone help me diagnose this issue and fix it if possible? The laptop has only the one HDMI port to connect any external monitor, so it I can't get this working I'm stuck using either the laptop screen or Windows. Thanks

  • Slow DNS Resolution

    - by user4541
    After a clean install of 10.10 I'm finding DNS resolution takes quite a long time. Hitting any url takes a good few seconds (10 - 30) before the site is displayed. I'm thinking this is a DNS resolution issue due to the 'waiting' or 'looking up' text being displayed in Firefox and Chrome. I do not get this issue with Slackware Linux or Windows 7 so it is not network or DNS server specific issue. It's something on the client side. Looking around on Google I see there are a few other people with this issue. The ones that have reported a workaround by switching to openDNS are disabling IPV6 or dealing with another issue. Any help would be appreciated. My network card is wired: Broadcom Corporation NetLink BCM5906M Fast Ethernet PCI Express Thanks

  • Laptop takes a long time to boot after Grub menu

    - by Andres
    I am running a Asus R401VJ laptop (Latin America version of N46VJ) that has a Core i7 CPU and 8GB RAM. After my Grub menu, which is displayed for 2 seconds as I set it up, I'm getting a black screen with a blinking white cursor that is increasing my boot time to about 60 seconds. After a while Ubuntu runs fine, I just want to reduce my boot time. I don't know if this has something to do with my never used Nvidia 2GB GeForce GT 635M graphics card. Always when I tried to install the driver, I ended up with a ~600x800 screen resolution, and I fixed it by deleting a file called: xorg.conf from the /etc/X11/ directory, following a suggestion that I read in another forum. I would appreciate detailed answers, I'm still new at Ubuntu.

  • A certain flash application causes a system crash

    - by noobermin
    It's no surprise I guess. Go here to try it! http://www.belgeler.com/blg/2hni/griffiths-introduction-to-electrodynamics-3-ed-solutions-manual It's wonderful, after a few seconds, top shows that our good friend plugin-container takes 83% of the physical memory (8 GB) before everything freezes and the PC doesn't respond. I'm using Ubuntu 12.04 and I have an nvidia (GTS 250) card with the "post-release updates" version of the driver. OFFTOPIC: Yes, it's the solutions manual. I'm self-studying so I don't have a professor to check my work. Please don't judge me :)

  • How to Save Hundreds or Thousands of Dollars on Cell Phone Service

    - by Chris Hoffman
    Cell phone contracts are bad. You get a seemingly cheap phone up front, but you more than pay for the cost of the phone over two years. Prepaid phone plans are surging in North America for a reason. Prepaid phone plans will be cheaper and more flexible than traditional contracts with big carriers for many people. However much you use your phone, there’s a good chance you can save money with a prepaid service. No More Contracts Here’s how cell phone service typically works in North America: You get a subsidized phone for “free”, $99, or $199. You sign up for a two-year contract and more than pay back the cost of that phone over the length of the contract. This is similar to leasing something or purchasing it on a credit card and paying it back over two years — you spend less up front, but you’re paying more in the long run. But this isn’t the only option. You could opt for a cheaper prepaid service that doesn’t lock you into a contract. If you don’t use your phone much, you could just pay for what you use and avoid the hefty cell phone bills. If you use your phone a lot, you could get a cheaper plan, too. Now, this certainly isn’t for everyone. If you want the latest iPhone or Galaxy smartphone every two years and require a 4G data connection, prepaid services may not be for you. On the other hand, if you don’t need the latest phone, you can save money here. You can also save a huge amount of money if you don’t use your phone much. Phone Options When you choose your prepaid or contract-free service, you’ll often be able to purchase a phone from them. You’ll generally be able to find dirt-cheap dumbphones and the cheapest, slowest Android phones for not very much money. If you are able to buy a top-of-the-line smartphone, you’ll have to pay the full, unsubsidized price. That’s $649 for either an iPhone 5S or Samsung Galaxy S4. Whatever phones the service provider offers, you could always buy a phone elsewhere — for example, you could buy an unsubsidized iPhone direct from Apple and then take it to your cell phone service of choice. Most services will allow you to get a SIM card and pop it into your existing phone rather than purchasing a phone. If you can get a hand-me-down smartphone, you can often save quite a bit of money. For example, you may have a family member upgrading from an iPhone 4S to an iPhone 5S. You could take their phone to a prepaid carrier and have a nicer phone on a cheap cell phone plan. If you brought an old smartphone to a big carrier like AT&T or Verizon, they wouldn’t give you a discount on your monthly plan. You’d have to pay the same amount of money every month as if you had gotten a subsidized phone. Google’s Nexus phones are also great options for people looking to buy smartphones and pay up-front. Google’s Nexus 4 offered a modern, almost top-of-the-line Android smartphone experience at $299 or $349 when it came out last year. Google will soon be releasing the Nexus 5 and it’s expected to be priced at $349. That’s certainly a lot more than a cheap phone, but it’s a fairly high-end smartphone at almost half the price of an iPhone 5S or Galaxy S4. Nexus phones can be purchased online from Google’s Play Store. Service Options When choosing a service, you need to consider what you actually use. If you’re someone who only uses your phone rarely, you can get plans that will allow you to pay as little as a few dollars per month. If you’re someone who’s usually in range of Wi-Fi, you may not need much data at all. If you want a plan with unlimited talk, texting, and data usage, you can get it for much cheaper than you’d pay on a major carrier like AT&T. The options here range from pay-as-you-go plans, like the ones offered by T-Mobile, which allow you to put a certain amount of money in and only drain that balance when you actually use minutes, texts, or data. If you only make a few calls and send a few texts per month, you’d only pay a few bucks. On the other end, Walmart’s Straight Talk service is a popular option that offers unlimited talk, texting, and data at $45 per month. Which service is right for you depends on a lot of things, including your usage and what each network’s coverage is like in your area. You’ll want to do some research of your own before choosing a service. Prepaid services also offer you even more flexibility after you choose one. If you’re not happy or a better deal comes along, you can switch — you’re not locked into your service for two years and you won’t pay an early termination fee.

  • Ubunti 12.10 wake on lan not working with Realtek 8139

    - by f.cipriani
    My pc doesn't wake up when receiving a magic packet from a pc connected to the same router. ethtool: fcipriani@ubuntu:~$ sudo ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Link partner advertised pause frame use: No Link partner advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: MII PHYAD: 32 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000007 (7) drv probe link Link detected: yes I have enabled all the wake up features in my bios, and I have verified the magic packet gets to the pc. I suspect the main problem is that the NIC light is completely turned off after the shutdown, but even after spending a lot of time researching I can't understand if this is a limit of my network card, my mobo, or something in the OS which needs to be configured correctly in order to leave the NIC in stand by mode with the light flashing. the NIC is Realtek 8139, the motherboard Asus P5L13L-X

  • ATI Proprietary Driver Over/Underscan setting ignored after reboot

    - by Lassi
    I installed the proprietary driver (fglrx-updates) on Ubuntu 12.10 64-bit for my graphics card (ATI Radeon HD 7570). I am using two displays, one connected with DVI, one with HDMI. I set the desktop to be expanded to both screens and disabled the under scan for the HDMI screen, which is always for some reason enabled on HDMI screens. Now the issue. Everything was fine until I restarted my computer. After reboot, the screen connected with HDMI cable had the black borders again, meaning that the under scan is again enabled. I checked the ATI CCC, and under scan was disabled. However, moving the slider to enable under scan and then back to zero fixed the issue -- temporarily. The same issue is repeated every time I restart my computer. The settings remains the same, but the computer seems to ignore it. Any ideas how I could solve the issue?

  • Hard-copy approaches to time tracking

    - by STW
    I have a problem: I suck at tracking time-on-task for specific feature/defects/etc while coding them. I tend to jump between tasks a fair bit (partly due to the inherit juggling required by professional software development, partly due to my personal tendancy to focus on the code itself and not the business process around code). My personal preference is for a hard-copy system. Even with gabillions of pixels of real-estate on-screen I find it terribly distracting to keep a tracking window convienient; either I forget about it or it gets in my ways. So, looking for suggestions on time-tracking. My only requirement is a simple system to track start/stop times per task. I've considered going as far as buying a time-clock and giving each ticket a dedicated time-card. When I start working on it, punch-in; when done working, punch-out.

  • Wireless not working, no driver showing in the Additional Drivers window

    - by edit lopez
    I am a new user of Ubuntu. I have a Asus Q501L laptop that came preinstalled with Windows 8, but I wanted to move from Windows and try something new, so I just decided to install Ubuntu without thinking to much about it. The problem I have is that I can't install the additional drivers. When I go to to Additional Drivers nothing appears, it just says: no proprietary drivers are in use and in small letters continues: a proprietary driver has private code that Ubuntu developers can't review and improve. security and others updates are dependent on drivers vendor.. I can't even use the wireless connection. I really don't know what to do. I tried to download the drivers from Asus, but when I tried to install them it said: an error occurred while loading the archive. Also I don't know the model of the PC wireless card. If there is something I can do to find out that please tell me. Thanks!

  • Sound Problem due to wrong driver installation

    - by Starx
    First of all, the audio used to play from the speaker but whenever I connected a headphone or speaker in the I, the sound didn't came. So I installed a realtek sound driver to fix this (actually I didn't find any relevant driver for my sound card so I installed it hoping it would show some light) When I rebooted the system, my sound is completely gone and now ubuntu does not detect any sound devices in my system. I clearly installed wrong driver, now I need to remove and go to previous stage and find a correct driver. My laptop is: Dell Studio 1747, uses a speaker Creative Labs Sound X-Fi MB Sound Blaster and the chipset is INTEL PM55. How can I fix this?

  • Aser Aspire 3690 WIreless Not working, new Ubuntu user

    - by drew
    I don't know that much about Ubuntu, but I put it on an Acer Aspire 3690 Laptop (replaced Win Vista). Everything seems to work fine, but the wireless connection. It says "FIRMWARE MISSING". It detects that I have a wireless card, so I don't know what to do. I've already used the "ADDITIONAL DRIVERS" thing, and that didn't work. I've googled and have not found anything helpful. I don't really know what I'm doing, so can your directions please be kindergarden level? Thank you very much for any help you can provide. I really appreciate it.

  • Broadcom STA driver doesn't work well with BCM4313

    - by Oli
    Following on from my other question about our new Samsung Q330, I've noticed that the wireless is incredibly flakey. It can connect but after a little use, especially if it does a lot of downloading at once (read: install something from the Software Centre), the connection stops working. Network Manager still see the connection, there's just no network throughput. I've simple tests like pinging other local network hosts and they just fail. The Samsung Q330 has a Broadcom BCM4313 wifi card (it's proper ID: 14e4:4727) and it's running on the Broadcom STA drivers that Jockey suggests (it didn't work at all without this). I did try installing b43-fwcutter but this just didn't do anything. I was expecting a configuration screen to come up (to select a firmware) but it never did. This page suggests the newer brcm80211 driver might be able to help, but I don't know how to install that. If you think this is the right route, please let me know how one goes about installing it.

  • Software requirements specification, please help!

    - by Nicholas Chow
    For a school project, I had to create a SRS for a "fictional" application. However they did not show us what it exactly entails, and were very vague with explanations. The SRS asked of us has to have at least 5 functional requirements, 5 non functional requirements and 1 constraint. Now I have tried my best to make one however I think there are still a lot of mistakes in it. Could you all please look at it and provide me with some feedback on which parts I can improve or just tell me which parts are plain out wrong and how to make it better? (The project has a maximum of 12 pages so it is a bit long, I will post it below. FR1 Registration of Organizer FR1 describes the registration of an Organizer on CrowdFundum FR1.1 The system shall display a registration form on the website.

  • PIN request at each login after update to Maverick

    - by Giacomo Verticale
    I have a netbook with included 3G mobile broadband card (Huawei E620). I have configured the broadband network connection in the Network Manager and it works perfectly. However since Maverick upgrade, a window appears just after login I asking for the SIMcard PIN. This happens every time I log in and did not happen with Lucid. Note that the PIN is stored in the configuration of the mobile broadband connection and Lucid was satisfied with that. Is there a way to prevent this request or, at least, to have the system rember the PIN and stop ansking for it? If it may be useful, the broadband network connection is configured as not being available for other users. Also, I would like to keep the SIMcard asking for the PIN; only I do not want to insert it manually at login.

  • Does FFMpeg support gpu acceleration of media encoding/decoding?

    - by Jason123
    I was wondering if ffmpeg supported gpu acceleration. I was reading on their websites and came across contradicting information. http://www.ffmpeg.org/general.html#Video-Codecs -H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (VDPAU acceleration) http://ffmpeg.org/trac/ffmpeg/wiki/x264EncodingGuide -Will a graphics card make x264 encode faster? No. libx264 doesn't use them (at least not yet). There are some proprietary encoders that utilize the GPU, but that does not mean they are well optimized, though encoding time may be faster; and they might be worse than x264 anyway, and possibly slower. Regardless, FFmpeg today doesn't support any means of gpu encoding, outside of libx264. If not, is there any way to add gpu acceleration to h.264 encoding/decoding?

  • Emailing Interviewer after interview regarding technical solution

    - by Raghav Shankar
    I had an interview yesterday where I was given a programming problem and I was asked to figure the optimal solution for it. I gave a solution that worked in linear time, but used 2 loops (not inner loops). At the end of the interview, the interviewer saw I was interested in solving the problem, so he said the optimal solution uses only one loop and has linear complexity and at the end of the interview I had asked for his card and he gave one to me. I think I might have figured out a solution and I was wondering if it's alright to email the recruiter thanking him for his time and also mentioning about the solution I had figured out?

  • Should I start learning WPF?

    - by questron
    Hi, I've been studying C# for about 2 months so far, I have a few years experience programming however in VBA and VB6, but nothing too in depth (I've written simple tools, but nothing too advanced). I am very interested in WPF and I was wondering whether it would be too early for me to start learning how to use it? For reference, I am about 400 pages into 'Head First C#' and I've written a program that can quickly tag image files for moving into a predefined folder or to delete (Allows the user to pull images off of a camera memory card and sort VERY quickly). That's the most advanced app I've written.

  • Replace Broadcom "wl" driver with "b43"

    - by Laszlo Boros
    I'm using Ubuntu 10.04.4 LTS, and in my laptop there is a Broadcom BCM4312 wlan card. lspci output: 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) Subsystem: Broadcom Corporation Device 04b5 Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at f4500000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [58] Vendor Specific Information Capabilities: [e8] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [d0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [13c] Virtual Channel Capabilities: [160] Device Serial Number 81-ac-1d-ff-ff-12-54-92 Capabilities: [16c] Power Budgeting Kernel driver in use: wl Kernel modules: wl, ssb So as you can see, the current (and default) driver is wl - installed with jockey.

So I would like to install it on this OS too, but even google didn't help me. So my question is how to install the latest b43 driver on my Ubuntu?

  • XFCE ~ Volume Hot Keys Not Working

    Just installed vanilla Xubuntu 12.04 LTS & updated on a ThinkPad E325 with Conexant CX20671 sound card. I notice volume hot keys work under Xubuntu DE but not XFCE. You can summon sound settings under Xubuntu but they are missing under XFCE. Also sound bar is greyed out though sound will still function. Muting/decreasing/increasing volume with hot keys has no effect. Is there a workaround? If not what package would I report a bug against?

  • Shotwell issues in 11.10

    I had used Shotwell happily previously then updated to Natty last week. Despite Shotwell showing on the tool bar on screen, when clicked, nothing happened, and it ignored my SD card when loaded. I read all sorts of remedies and tried everything to no avail. When I next turned on the laptop, Ocelot was available so with nothing to loose, I upgraded again. Still no Shotwell. Tried all the new fixes and now atleast I have the icon pictures but nothing behind it. When I ran the command to load the log file, Shotwell loaded and all my photos are present. Exited programme, and now nothing. Can anyone tell me where I have gone wrong please.
