  • Thinkpad T530 with Optimus and Docking Station

    - by Vic Boudolf
    I have a Lenovo Thinkpad T530 with Optimus video, which is not supported on 12.04.1. I don't normally need the discrete (nVidia) graphics, so I turn it off in the BIOS settings to achieve longer battery life (and so that the screen dimmer will work), but when placed in the docking station, the integrated (Intel) graphics don't power the HDMI ports. (The VGA port does work, but I want to focus on the HDMI.) This means I have to change the BIOS settings constantly. Is there any way to have the system detect the docking station and power up/enable the discrete graphics accordingly? I don't need to do it on the fly. Just at startup. This post suggests that bumblebee can turn the discrete graphics on and off for specific applications, but I just want to turn it on or off. [2 suggests that vga_switcheroo will not work with nVidia Optimus.

  • How do I shutdown 12.10 when ACPI is set to OFF?

    - by rahi
    I recently installed 12.04 on an HP Spectre XT ultrabook. I installed 12.04 from a USB. When the install was complete, and the computer restarted, I got a blank screen. After some searching, I found that I had to choose "acpi=off" during the installation, which now shows up in the grub screen. Once I was on 12.04, I upgraded to 12.10. The issue now is that when I hit shutdown, the computer hangs on a purple shutdown screen. Usually, at this point, I press the power button on the machine to completely power off the machine. I am new to ubuntu, and would appreciate the help. Thanks.

  • Ubuntu 12.04, web cam light flashing

    - by user205877
    Have been running Ubuntu on my Compaq C757 reliably since 9.10. Currently running a fresh install of 12.04 LTS. Somewhere during my regular updates, my webcam started flashing its power light. Light flashes from logon screen all throughout my session. I am not running Google Chrome but chromium and firefox. Webcam works normally whenever I run Cheese webcam booth, light comes on solid and webcam works normally. I close out of Cheese, webcam shuts off, and then the light starts blinking again. My system is dual boot, when I boot into Windows 7, webcam does not exhibit this problem. I suspect issue may be related to new laptop power management settings in kernel based on research on the web of similar problems, but I do not know how to instruct it to treat webcam differently.

  • Can I use Ubuntu as a wireless media server which performs all decoding/processing server-side?

    - by AthloX
    I want to setup UBUNTU 12.04 desktop as Home media server. I have window 7 netbook and UBUNTU 12.04lts laptop even a samsun galaxy note tablet (android). Two desktop in other room with dualboot win7 and ubuntu. SHARP AQUOS Plasma Tv with Wi-Fi connected. I want to install ubuntu as media server to stream audio/video files over wi-fi. Not only this i want this media server to use its own processing power to decode ans stream so that on remote end only file can play without using their own resource. Is it possible to use ubuntu as media server to stream files without making the remote end to use there own resource. I want only bandwidth of Wi-Fi to be use in this and media center hardware resource.Remote end gadget should use only speaker and screen and not processing power of their own. Please any suggestion is it possible to do so ?

  • WUBI install not completing on Dell Latitude D600 using 10.04 and 10.10

    - by Dennis
    While trying to install a dual boot from LiveCD, WUBI seems to go through all the steps correctly. It unpacks everything, reboots, starts to finalize the install, brings up the install slide show and seems to do everything necessary. The slide show disappears and what is left is what would normally be the background, however there is no login, no panels, no response to any input or keystrokes. Using 10.04 I had a mouse cursor (working) with 10.10, not even that. In 10.04 The only way to reboot is to shutdown using the power switch. When it reboots it goes through the "finalizing install" phase again. In 10.10 if I hit the power switch it brings up a shutdown menu that doesn't respond to the keyboard, but does shutdown when the 60 seconds expire.

  • CES 2011–Microsoft Keynote Impressions

    - by guybarrette
    Microsoft has been kicking off the CES for a number of years by doing a keynote the evening of the event first day.  This year, SteveB talked about Xbox, Kinect, Windows 7 new laptops, Surface 2 and Windows vNext running on the ARM architecture. Some of the design of the new laptops showed are quite amazing.  This one has a dual screen with no physical keyboard.  The image is split between both screens.  A software keyboard appears when you place your 10 fingers on the lower screen. This one from Samsung has a sliding keyboard somewhat like numerous cell phones have. What I found the most amazing is that Intel was able to miniaturized a full Intel architecture (CPU, motherboard, memory) in a tiny form factor.  Imagine having the power of a full PC running .NET apps in a Zune/iPod form factor! They also showed V2 of the Surface device.  This one is called the Samsung SUR40 for Surface PC.  It’s much sleeker and it will likely loose the BAT (Big Ass Table) moniker  More info here SteveB announced that Windows vNext will run on ARM chips.  I’m intrigued by this announcement (you can read about it here) and I have many questions: -In the past ARM devices were slow, what now makes the ARM architecture able to run Windows? -ARM is 32-bit only, I think. -Does this mean that Intel wasn't able to provide such a lightweight architecture or simply that they weren't interested? -From what I understand, apps would need to be recompiled for ARM. Will we need to do that from an ARM PC or could it be done natively on Intel or on an Intel PC running in an ARM VM?  VS 2012? Ahhhh, smells like a cool PDC is coming up    Clearly it looks like PC have enough power for most of us right now and that the race is now about miniaturization, power consumption and battery life. You can watch the Microsoft CES 2011 keynote here var addthis_pub="guybarrette";

  • Why are my USB 2.0 devices crashing Windows XP?

    - by BenAlabaster
    Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a generic ATX motherboard with no identifying markings other than one stamp that says "Rev.B". CPU-Z identifies the motherboard model as VT8601 but doesn't provide me with any manufacturer name. On board it has 1 x 10/100 LAN, 2 x USB 1.0, VGA, PS/2 for KB and mouse, parallel port, 2 x serial ports, 2 x IDE, 1 x floppy, 2 x SDRAM slots, 1 x CPU housing that is seating a 1.3GHz Intel Celeron CPU, 3 x PCI, 1 x AGP - although you can only use 2 of the PCI slots if you use the AGP slot due to the physical layout of the board. It's got 768Mb PC133 SDRAM - 1 x 512Mb & 1 x 256Mb installed as well as a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board containing 3 x external + 1 x internal USB connectors. It has a DVD+/-RW running as master on IDE1 and a 1.44Mb 3.5" floppy drive connected to the floppy connector. It has an 80Gb Western Digital hard drive running as master on IDE0. All this is sitting in a slimline case. I don't know the wattage of the PSU, but can post this later if this proves to be helpful. The motherboard is running a version of Award BIOS for which I don't have the version number to hand but can again post this later if it would be helpful. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine?

  • Why can't my Wifi connect or disconnect?

    - by tmy1018
    Wifi connection might drop spontaneously or simply cannot connect. Users on Ubuntu 10.04 and 11.04 have reported experiencing the problem. Running dmesg would show: [210749.637705] wlan0: deauthenticating from 00:23:89:48:3b:b0 by local choice (reason=3) [210778.632244] wlan0: deauthenticating from 00:23:89:48:3b:b0 by local choice (reason=3) [210784.456359] wlan0: deauthenticating from 00:23:89:82:75:70 by local choice (reason=3) which is pretty cryptic. I have tried: kill -9 wpa_supplicant, but wpa_supplicant keeps getting restarted each time. Also, some have suggested that this was caused by enabling power management. However, this might not be true, as the problem has presented itself in a situation where power management was disabled.

  • What is the ideal laptop for creative coding applications?

    - by Jason
    Hi, I am a creative coder using C++(cinder and OpenFrameworks) I am looking to upgrade from my MacBook, which slowed down to about 3fps this morning. My project involves particles systems and fluids reacting to audio analysis data and computer vision data in real-time. SD or HD? no biggie. I have asked many people what computer I need. Ideally, I want a MacBook Pro. But is that enough power? I've been told that I need a desktop for what I am doing though I'd rather stay portable I've been told that I should go PC linux to get the most power but I'd rather stay mac I've been told that RAM is more of bottleneck than processor speed I've been told that the Graphics Card is more important than CPU and that code optimizations such as using trees over lists, proper threading, sending tasks to the GPU make a bigger difference than the hardware!!! what's true?! what do I need? Any suggestions are greatly appreciated

The magic happens when you mix these ingredients together. The same goes for the hottest technologies fast changing how IT impacts our organizations today: cloud, social, mobile, and big data. By themselves they’re pretty good; combining them with a great recipe is what unlocks real transformation power. Choosing the right cloud can be very similar to choosing the right cake. First consider comparing the core ingredients that go into baking a cake and the core design principles in building a cloud-based application. For instance, if flour is the base ingredient of a cake, then rich functionality that spans complete business processes is the base of an enterprise-grade cloud. Cloud computing is more than just consuming an "application as service", and having someone else manage it for you. Rather, the value of cloud is about making your business more agile in the marketplace, and shortening the time it takes to deliver and adopt new innovation. It’s also about improving not only the efficiency at which we communicate but the actual quality of the information shared as well. Data from different systems, like ingredients in a cake, must also be blended together effectively and evaluated through a consolidated lens. When this doesn’t happen, for instance when data in your sales cloud doesn't seamlessly connect with your order management and other “back office” applications, the speed and quality of information can decrease drastically. It’s like mixing ingredients in a strainer with a straw – you just can’t bring it all together without losing something. Mixing ingredients is similar to bringing clouds together, and co-existing cloud applications with traditional on premise applications. This is where a shared services  platform built on open standards and Service Oriented Architecture (SOA) is critical. It’s essentially a cloud recipe that calls for not only great ingredients, but also ingredients you can get locally or most likely already have in your kitchen (or IT shop.) Open standards is the best way to deliver a cost effective, durable application integration strategy – regardless of where your apps are deployed. It’s also the best way to build your own cloud applications, or extend the ones you consume from a third party. Just like using standard ingredients and tools you already have in your kitchen, a standards based cloud enables your IT resources to ensure a cloud works easily with other systems. Your IT staff can also make changes using tools they are already familiar with. Or even more ideal, enable business users to actually tailor their experience without having to call upon IT for help at all. This frees IT resources to focus more on developing new innovative services for the organization vs. run and maintain. Carrying the cake analogy forward, you need to add all the ingredients in before you bake it. The same is true with a modern cloud. To harness the full power of cloud, you can’t leave out some of the most important ingredients and just layer them on top later. This is what a lot of our niche competitors have done when it comes to social, mobile, big data and analytics, and other key technologies impacting the way we do business. The transformational power of these technology trends comes from having a strategy from the get-go that combines them into a winning recipe, and delivers them in a unified way. In looking at ways Oracle’s cloud is different from other clouds – not only is breadth of functionality rich across functional pillars like CRM, HCM, ERP, etc. but it embeds social, mobile, and rich intelligence capabilities where they make the most sense across business processes. This strategy enables the Oracle Cloud to uniquely deliver on all three of these dimensions to help our customers unlock the full power of these transformational technologies.

  • T420 Triple Head with Optimus

    - by Rolo
    I see that this is possible on a T520 apparently (Triple-head on a Lenovo T520), but I can't see anyone claiming it's possible on a T420. I'm running 12.04 and have Bumbleebee installed and working fine but I can't get the display port monitor to display anything. The power light flicks on, but things only render on my VGA output monitor, and Ubuntu's display settings don't detect the third monitor. I'm not concerned with power management, ie, am happy to leave set on discrete graphics in the BIOS if that helps. Is this possible? Thanks.

  • My Dog Ate My Surface

    - by Richard Jones
    Working for a Microsoft partner I was very fortunate enough to be given clearance to order a Microsoft Surface RT tablet. Justification, show new device to a customer event this Thursday. All good, time to develop an App. Surface arrived last Wednesday. Overnight, Coco our much loved one year old puppy Larba-Doodle pulled the power chord out of my bag and bit right through the cable (at the power-brick end). A quick re-order to Microsoft saved the day. Demo went great. Surface is fab, Coco; much loved too Laptop bag now placed a bit higher up in our house.
