[SOLVED] KDE, Certain Desktop Effects require OpenGL but can't set it

Certain desktop effects give me an error when enabled (or rather when I try to enable them) saying that they require OpenGL.
I changed the Compositing type to OpenGL and the Qt graphics system to Raster (also tried with the default Native), and I get an error saying that it Failed to activate desktop effects given configuration options.
How can I enable OpenGL and get it all working properly?

What's you graphics card and drivers? You can have working openGL but your card can be to old to support all the extension required by particular effect. Other effects are working ok and just couple of them are giving error, right? If so it's ok.
Also paste output of glxinfo | grep -i render

  • [SOLVED] KDE buggy desktop effects in OpenGL

    Hello, I've been using gnome as my desktop environment for a while now and I decided to give KDE a try once again, but I'm having some issues.
    Everything was perfect:
    http://i42.tinypic.com/14l1x8p.jpg
    But I noticed that whenever I snap a window to any side of the screen and the stretching effect is displayed this happens:
    http://i44.tinypic.com/dm9oyg.png
    And If I go back to a small window:
    http://i40.tinypic.com/104p15i.png
    Now, as soon as I click elsewhere those black/invisible boxes are gone.
    As you can see I checked under system settings >> desktop effects >> advanced and, if I change the Compositing Type to Xrenderer the problems are gone, but as you can imagine that is not ideal, this ONLY happens when I select ANY version of OpenGL as the Compositing Type.
    I use the proprietary AMD drivers for my HD 6770, I think this problem might have something to do with that.
    Any help would be appreciated.
    Thanks in advance.

  • Does adobe after effects require OpenGL?

    Hello, I'm purchasing a new laptop, and I'm trying to find one with a graphics card that has openGL, but I'm having a hard time doing so, but, does adobe after effects require openGL? and if so, could anyone recommend a laptop in the $400-$600 range?

    > Open GL is not mendatory but for one effect which is the cartoon
    effect. And i think that pixel bender plugins needs open gl too, but
    i'm not dead certain.
    No, OpenGL is not required for Pixel Bender plug-ins or for the Cartoon effect (which is written using the same underlying technology as Pixel Bender plug-ins). The Cartoon effect is certainly much faster when you have a graphics card; if you just run it on the CPU, it's quite slow.
    In all cases, things that can run on the GPU (the chip on the graphics card that OpenGL is making use of) can also fall back to running on the CPU.
    Personally---as Sebastien suggested---the Cartoon effect is the only thing other than interactive previews that makes me glad to have an OpenGL-capable GPU.

  • What is the name of the folders which are your backup of Itunes library? I am recovering from a virus, have no workable desktop in Win XP, but can search and find files and folders. I would like to move these backup files to a new computer

    what is the name of the folders which are the backup of Itunes library? I am recovering from a virus, have no workable desktop in Win XP, but can search and find files and folders. I would like to move these backup files to a new computer, authorize it and sync with Iphone 3Gs and Ipod 5th gen.

    I second the whole iTunes folder approach.
    If for some reason you have split the media folder from the library files then the media folder needs to restored to the same path it used to have while the library files can be copied into the music folder of your new profile.
    If in dobut, backup up the entire Documents and Settings folder before wiping the infected drive, but be selective about what you restore as many viruses drop active components capable of reinfecting the compuer in the temp folders and internet caches. It is much easier to backup more than you need than to discover after the fact that you no longer have access to some vital project you'd been storing in a folder on the desktop.

    You would have to create the ringtone.  Google will find several ways to do this.

  • Just purchase ipad3 trying to play from favorites in you tube but can't set up a play list, username /password not recognised, tried some apps like SoundBox but same issues, can anybody help?

    Just purchase ipad3, trying to play you tube favorites but can't set up a play list (username /password not recognised)
    Tried downloading apps such as SoundBox but no joy
    Can anybody help?

    Thanks for that. Much more constructive than the last comment. It's only the restriction code I can't recall, not the access passcode. So I can currently access the device, just not age restricted content. Does that's make a difference? I also wondered if anyone knew how many attempts you get to try to get it right. Now tried 21 times and so far nothing bad has happened but I am concerned I'll eventually be completely locked out of the device. That doesn't seem in the spirit of things though. Surely it's foreseeable that a child could repeatedly try to guess the code so I can't see that it would be right to lock the device down completely in that circumstance, particularly if the access code is being typed in correctly every time.
    Thanks

  • Trying to find specific effect in AE but can't seem to locate. Vid example available.

    There is an effect used extensively in this video: http://vimeo.com/4803532
    Notably at 0:56 and 2:45. It is a repeating effect. I have used it before in AE a while ago but can't seem to figure out how to do it again. If someone could please just direct me to where it is and what it's name is you would really make my Christmas Eve.
    Thanks guys.

    Echo is it! Hiding in the time tools. I guess that makes sense. Thanks for the help yet again Mylenium!

  • [solved] Hiding certain .desktop files in the XFCE menu?

    Is there a way to hide .desktop menu entries in the XFCE menu without removing them from the system?
    For example, there is an entry called "Recording Level Monitor" after installing some gnome dependencies for rhythmbox.  It's a useless app to me and I'd like to have it hidden for good.  I suppose I could delete the .desktop file, and I wouldn't hesitate to do so, but I have the feeling it'll keep coming back on -Syu's.

  • Download After Effects 2014 failed but can't uninstall - error5

    The attempted install of After Effects 2014 has failed which I'm informed of when I try to launch.
    The message also tells me to uninstall and reinstall.
    When I attempt this, however, the uninstaller only shows Adobe Type Support CS5 and this also fails if I try to use it.
    I've restarted and run the cleaner tool which has now removed the previous version of AE.
    What the hell is going on and what do I do?
    OSX Mavericks.

    In this case, the Error 5 is an AMT error at launch, not the corrupted file error you're thinking of. Most likely there is some bad or missing data in the AMT database files (PCD/Caps), and using the newer CS5 Clean script to remove just the CS5 product data, then reinstlalling, would solve the issue

    Hi pkw3tgw-
    Here are the steps to reinstall Firefox and upgrade to the latest version:
    * Get the latest version: http://www.mozilla.org/en-US/firefox/new/
    * Uninstall your current Firefox version.
    * Do not remove personal data when you uninstall the current version.
    * Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
    * It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
    * Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

  • Solved: Installed Xcode 4... But Can't Find It.

    Hi, there
    So I bought Xcode 4 from the App Store. I always thought Xcode was free, but Apple charge for it now. So once it finally downloaded, I tried installing. The installer got stuck at 98% (as it does for many people). I used the trick mentioned in another thread where you look at the package contents and find the installer file in there ("Contents" > "Resoures" > "Xcode and iOS SDK.mpkg") and install it that way. That worked, however, I can't find the SDK or Xcode applications anywhere on my Mac. Spotlight returns nothing.
    Any ideas?
    EDIT: Nevermind, found it in the "Developer" folder. I thought it'd be stored in the applications folder. Not sure why Spotlight didn't pick it up.
    Thanks,
    Chris

    It's installed in another 'Applications' folder as you found out, which makes for fun until you're comfortable with the process, etc.
    Would be easier if they didn't do that as part of the install, but hey...at least it works.
    And don't be tempted to move Xcode to another folder...leave the content of /Developer as-is.
    Spotlight may not have had time to index the new files, BTW.

  • [SOLVED]fresh install of arch 2009.2, but can't install xfce4

    Hello all,
    I'm not new to Linux or any of the *BSD's, been at it for quite a few years. I am new to Arch, though.
    I really like what I've learned about it so far, and really want to embrace it as a main system, but I'm having a hard time getting off the ground. I want to install xfce4, but I keep getting this error:
    xfce4-settings: conflicts with xfce-mcs-manager
    It errors-out immediately. I read about a similar error in this forum, but never really discovered a fix.
    Please help, and much appreciated in advance.

    You could be a little more specific.

    xfce-mcs-manager
    xfce-mcs-plugins
    And some more conflicts in the optional xfce4-goodies group:

    Those packages should be ignored for a successful XFCE 4.6 installation.

  • [Solved] Unable to connect to wireless network, but can see it.

    Hi,
    I hope someone can help me figure this out. I'm attempting to install Arch on a new computer and having trouble setting up the wireless.
    Running "lspci -k" I see that I have an Intel network controller which uses the iwlwifi driver.
    "dmesg | grep iwlwifi"
    contains the line "loaded firmware version 9.221.4.1 build 25532 op_mode iwldvm", so it looks like the driver is working properly.
    When I run "wifi-menu" I can see my university's networks. I then select one and am prompted to save the generated profile. Upon doing so I receive a "CONNECTING FAILED" error.
    I'm not sure where to go from here, so any advice would be greatly appreciated.
    Edit: The problem was with my university wifi not recognizing my MAC address. It's solved now.

  • I just had Uverse installed.  The iMac which was my base station is now connected via my household electric ground connection.  Another computer is now the base station.  I have connected my Time Capsule to my computer by USB cable, but can't set it up

    I just had Uverse installed.  My iMac desktop has been the base station for my wi fi, but we had to connect it via ground wire of my electrical system and use another desktop as the base station [with windows op system].  We have connected my Time Capsule to the computer via USB cable.  I believe that will require setting up the Capsule to use Ethernet, but the instructiions on the install disc only talk about using Airport.  How can I find instructions for setting up using USB cable and Ethernet?
    Thanks!

    All the manuals are listed at the head of the thread.

    The TC cannot connect to the computer by USB.. it is network device.. it only connects by ethernet or wireless.. usb is for external drive or printer.

    You could use templates, but I prefer using includes (PHP in my case). Server Side Includes (SSI) are great since once your pages are linked to it, you only need to upload one file for any changes to effect the whole site. More information on SSI is available via F1
