    Migrated to Linux (Ubuntu).. Need help

    Hi there,

    I have recently left Microsoft behind after the umpteenth system failure, and am committed to making a full transition to Linux.
    I chose Ubuntu 12.04.01 64 bit, as my assumption was that Ubuntu would have the best support for hardware, and I also was impressed by its ease of use compared to other distro's software managers.

    Everything installed fine, and I thought all was well.

    But:
    1. When surfing on Chrome, there are several webpages that do not function properly and seem broken (scroll bars do not work, cannot fill in forms etc.) and there are glitches while watching Youtube.

    2. At the same time when watching a high-def movie with VLC, after 30 minutes (aprox) the sync goes to hell.

    3. I have at the same tame noticed that the CPU load is very erratic never falling bellow 14% and spiking intermittently at 76-100%.

    I have installed restricted drivers, and tried both installing catalyst from AMD's webpage and tried the propitiatory drivers in Ubuntu's "additional drivers" menu, but alas nothing is helping.

    Can anyone guide me in the right direction?
    I consider myself semi-computer literate, and can usually find sollutions online my self, but not this time.
    Is this a Kernel issue?
    Would I have better luck waiting for 12.10 (newer kernel)
    Should I consider a different distro?

    My specs are:
    Intel I5 275 on MSI P55-CD53 motherboard
    ATI HD 4890 1GB
    60 GB SSD, 1TB WD caviar for /home folder
    16 GB Corsair Vengeance (because I could )

    Thanks in advance

    P.s.

    If this is a GPU issue, what are my options? As far as I can make out there might be support problems for the HD 4xxx series in linux. Does this mean I have to buy a new GPU

    Thx for the heads up Ace.

    I will give it a try.

    In the mean time I have read that flash hasn't been very well supported on 64 bit. I never had problems using FF or Chrome in Windows, so I assume this as well is a Linux issue.

    I chose Chrome over Firefox due to Adobe not supporting Linux any longer. But is this still the case?

    Not sure of the politics, but I run chrome and firefox as my normal setup.

    For firefox, I installed flash-aid - its a an icon that will live top-right of firefox.
    It will load the correct code for your sys.

    It works a treat.

    By using both these fixes, both my browsers are flying along.
    Chrome flies just that little bit faster (as it happens).

    Regarding browsing in Chrome.
    Install flashplugin-installer package.
    Then in Chrome goto chrome://plugins, click details in the right corner and disable pepperflash.
    Pepperflash which is built in Chrome does not work well with AMD graghics.

    Adobe does not make new versions of flash for linux, but they issue security updates for 11.2. It works quite well.

    Hi all, and thanks to everyone that has replied.

    I have installed URE and the XVBA-VA-driver.

    I went into Chrome, but could not see pepperflash anywhere.
    What I have is:

    Flash (2 files) - Version: 11.4.31.110
    Shockwave Flash 11.4 r31
    Name: Shockwave Flash
    Description: Shockwave Flash 11.4 r31
    Version: 11.4.31.110
    Location: /opt/google/chrome/PepperFlash/libpepflashplayer.so
    Type: PPAPI (out-of-process)
    Disable
    MIME types:
    MIME type Description File extensions
    application/x-shockwave-flash Shockwave Flash
    .swf
    application/futuresplash FutureSplash Player
    .spl
    Name: Shockwave Flash
    Version: 11.2 r202
    Location: /usr/lib/flashplugin-installer/libflashplayer.so
    Type: NPAPI
    Disable
    MIME types:
    MIME type Description File extensions
    application/x-shockwave-flash Shockwave Flash
    .swf
    application/futuresplash FutureSplash Player
    .spl

    Still the same problem on say Facebook. Nothing works.

    There must be a way, but until I can find a fix I will have to start using Firefox (which was my preferred browser until I was persuaded to try Chrome).

    The next experiment wil be to see how the GPU is faring. I was thinking of installing Playonlinux and trying to install some of my Windows games (Skyrim?), or should I try a native game. I just want to pressure test the system.

    I will try to watch a HD-movie to see if there are still any glitches.

    RE pepper flash

    I had the same prob as you..... unable to find it.
    Hence why I figured out the fix that I first posted to you.

    It might not be elegant..... but it definitely worked/works and it solved all the display problems I had in chrome, and dramatically speeded it up.

    @Ace: It worked!

    Thanks a lot. I presume that I will have to launch Chrome from the Desktop from now on, but that is a minor inconvenience.
