  • Backlight turns off when launching Braid

    - by tone0511
    I have Ubuntu 12.10 on Acer Aspire 4736z and I installed Braid. When I have just turned on the computer, login and then launch Braid right away, it works just fine. But when I have already been using the computer for some other tasks like browsing or typing on Open Office after booting up and then decide to play Braid, the backlight turns off and I cannot turn it back on using the screen brightness control buttons. I have uninstalled and reinstalled Braid but it's the same. Please help me. Thanks.

  • Intel GMA 4500M screen resolution problem

    - by I Heart Ubuntu
    I was previously running 10.10 on my Acer Aspire laptop. It has Intel GMA 4500M integrated graphics and worked just fine. Great display, sharp, crisp, etc. I decided to do a fresh install of 11.10 Oneiric and now am having problems. Originally I was getting the dreaded blank screen where the brightness was turned almost completely off. Some searching pulled up several easy fixes (editing GRUB). Right now I am still having one issue. The screen resolution is stuck at a max of 1024x768 giving me a distorted screen. Is there any way to fix this issue? I've Googled, searched Ask Ubuntu and also spent time on the forums looking for a solution. Thus far, nothing. Apparently, was and still is a concern in Natty? Any help would be greatly appreciated.

  • Dell Inspiron N5110 Battery lasts only for 1.5 hours as opposed to 4 hours on Windows 7

    - by ubuntufan
    I've a Dell Inspiron N5110 laptop with the following specs: i5 processor 4 GB RAM NVIDIA GeForce GT540M Ubuntu 12.04LTS My laptop is overheating and the battery is lasting for only about 1.5 hours. I had checked if the battery indicator was problematic but it turned out it wasn't. I drained the battery to it's least possible value and that came to around 1 hr 40 minutes. In fact, I've the same problem with Debian and Xubuntu as well. I would like to get some proper solution for this. FYI: I've been having this problem since Ubuntu 11.04 but I'm not able to solve this in spite of trying various fixes like reducing brightness, Removing startup apps, Updating kernel and what not?. I'm a big fan of Ubuntu but this problem is stopping me from using Ubuntu and I'm using Win7 for 90% of the time.

  • How do I turn off the laptop screen while using an external monitor?

    - by jpmelos
    When I close my laptop lid, all my screens are turned off (my laptop screen and my LG M237WA monitor). I'd like to know how do I make it turn off only the laptop screen and keep the monitor on (I want that behaviour for when I want to watch a movie on my monitor and don't want any brightness coming for the laptop screen). I'm using a HP Pavilion dv4-1290br, which comes with a nVidia GeForce 8400M GTS. I'm using the nVidia driver and it's working perfectly. For my X settings, I'm using TwinView, my laptop is set to 1280x800 and my monitor to 1920x1080. I hope you guys can help me, for I couldn't find anything so far. Thank you very much.

  • Unable to make Window transparent in Ubuntu 12.10

    - by Falguni Roy
    I have recently upgraded from ubuntu 12.04 LTS to 12.10 (x64). I used to have transparent window tittle bar using gconf-editor -> apps -> gwd. But in 12.10 editing the value isn't doing nothing. Also in ccsm many plugins such as: opacity, brightness, saturation, desktop cube and rotate cube are all gone. I love that transparent look very much and I want to get it back in 12.10. I'm using Nvidia 7200GS ; AMD Athlon 7750 ; 3GB Ram. Is there any way to get it working?

  • Video Bug in Ubuntu 12.10 MSI CX623 laptop

    - by user104731
    http://www.youtube.com/watch?v=5xyJkS8XjgA&feature=youtu.be I managed to take a video with what happens on my Ubuntu 12.10 laptop when I play with the volume and hover with the mouse over the slider and when I press Ctrl + Alt + D (show Desktop/minimize all) The real bugs are those in which the panel becomes transparent on the down side, exactly above the volume slider (and not only when that slider appears, but also when brightness slider appears, and when blocking my touchpad applet appears) and when I have a maximized window, more maximized windows or a non maximized window that touches the panel, while I use Ctrl+Alt+D (show Desktop/hide all normal windows). Is there a way to solve this bug? PS: The other bugs are from Record My Desktop. I didn't have the mentioned bugs in ubuntu 12.04, but I like more the graphics in 12.10.

  • How to improve battery life on a HP Pavilion dv6?

    - by user1793249
    I apologise if this question is too similar to the numerous others already asked, but I'm a beginner and I really need your help. So...I've installed Ubuntu 12.10 a few days ago and I have only been able to get up to one hour of battery life. When running Windows 7 I get up to 3-4 hours. My screen is ultra bright, even tough the screen brightness is set to the minimum (I installed xcalib to dim my screen, but it doesn't improve the battery life) I read about Jupiter and installed it, but it doesn't have a noticeable effect. Thanks for your time.

  • Encode complex number as RGB pixel

    - by Vi
    How is it better to encode a complex number into RGB pixel and vice versa? Probably (logarithm of) an absolute value goes to brightness and an argument goes to hue. Desaturated pixes should receive randomized argument in reverse transformation. Something like: 0 - (0,0,0) 1 - (255,0,0) -1 - (0,255,255) 0.5 - (128,0,0) i - (255,255,0) -i - (255,0,255) (0,0,0) - 0 (255,255,255) - e^(i * random) (128,128,128) - 0.5 * e^(i *random) (0,128,128) - -0.5 Are there ready-made formulas for that?

  • Adobe Color Profiles/Color Spaces, how is it possible that this works?

    - by leeand00
    I'm learning about Color Profiles/Color Spaces/Monitor Color Management Profiles and I was just wondering how any of that justified considering the fact that I could throw the entire color anything off by adjusting the brightness and contrast of my monitor? Additionally there are things like lighting in the place where your monitor resides. I don't understand what makes it possible to know that the colors that you are looking at on your monitor are accurate. I really don't have any idea where to start (considering I obviously can't even get the terminology right in the first place...:-p)

  • Simulate Photoshop's saturation changes in Imagemagick

    - by Ambirex
    In Photoshop you can adjust the hue, saturation and lightness of an image with three sliders. ImageMagick you can modulate the brightness, saturation, and hue. Minimizing the saturation correctly produces a black and white image in both programs. Maxing out the saturation appears close, but ImageMagick appears to soften some of the blown out edges while Photoshop will expose more the the compression artifacts. How can I accurately reproduce Photoshop's saturation changes from within ImageMagick, or other command line tool.

  • Is there any live video stream editing open source project with API for my needs?

    - by Ole Jak
    I need an open source project with an API capable of reading a live video stream (stream codec can be any API can read - I can provide with practically any live streamable one) giving me last image data for some processing (like brightness\contrast or more exotic filtering) being able to receive data I've changed and starting to stream that data on to some http://localhost:port/ in some format I need it to be easily accessible from C# (even better, written in C#).

  • Image editor component in Flex / JavaScript

    - by nobby
    Hi everyone, I'm looking for a simple Flex or JavaScript based image editing component which can be embedded in a web application. It shouldn't be a web service but rather a component that I can download and customize (i18n etc.). I only need some basic features: most important is cropping, optional features would be rotating and adjusting brightness/contrast. Basically something like splashup.com, but as an open source application rather than a web-service. Thanks a lot in advance for any hints! -- Andreas
