    Problem with graphics


    Hello everybody,

    I've been experiencing some kind of graphics problem, happening mostly
    when I move down the page in browser, pdf viewer, etc... with mouse
    wheel. It doesn't go smoothly. Some lines are cut and I can't see whole
    text clearly. It's kind of hard to explain for me, so I took a
    screenshot to show what exactly happens.

    [image: http://img820.imageshack.us/img820/4...phicsbug1.png]

    I have no idea, why that happens. I have the latest video drivers
    installed I believe.

    Re: Problem with graphics


    What version of SLED are you using?

    Code:
    --------------------
    $ cat /etc/novell-release
    --------------------


    What video card do you have and what drive are you using?

    Code:
    --------------------
    $ /sbin/lspci -nn -k
    --------------------


    When did the problem appear? (Did you just install SLED? Have you had
    it installed a while and the problem occured after you installed updates
    then rebooted? (If so look at /var/log/zypp/history to see what was
    installed) Other?)

    Do you have Desktop Effects enabled? Or to put it another way, are you
    using metacity or compiz. With Desktop Effects enabled you're using the
    Compiz window manager, otherwise, metacity. You can look at the output
    of

    Code:
    --------------------
    $ ps U $USER | grep metacity
    $ ps U $USER | grep compiz

    --------------------

    I'm not sure, when did it start. But I suppose this might have started
    when I installed those new drivers (not sure though).

    Sounds like a likely candidate. What new drivers did you install and
    where did you get them from? Have you tried reverting to whatever driver
    you had before?

    You have two VGA cards listed in the output of lscpi, what looks like
    an onboard Intel and an ATI (from the vendor/model number looks like AMD
    Radeon HD 6470M is that right?). I've never seen that myself but maybe
    that's fine. My machine has onboard Intel graphics and a discrete Nvidia
    card. I use the Nvidia card and the onboard Intel graphics does not show
    up in the output of lspci. Are you using both graphics cards?


    What does this say?

    $ glxinfo | head

    I got the drivers from ati 'ATI Catalyst'
    (http://support.amd.com/us/gpudownloa...eon_linux.aspx) .
    Well actually, I see that my drivers are not latest now. AMD catalyst
    shows that I have 2 cards, but I have high performance GPU (my card is
    radeon 6470M I believe) selected over intel.


    AlexDudko:

    Adobe acrobat is not the only one causing problems. The same happens
    with mozilla (which, by the way, was included in SLED, is version 3.6 at
    the moment and I can't find how to update it).

    Well direct rendering is enabled, so that's good.

    When you registered your machine the repos that get set up should have
    included one for ATI graphics drivers. Is there a reason you're not
    using the drivers from that?

    My only experience with ATI graphics and Linux was about 8 years ago.

    I assuming you mean Firefox rather than Mozilla. (Firefox being the web
    browser, Mozilla being the company that makes it.) The 3.6.xx branch of
    Firefox is still being supported by Mozilla so it's still OK to be using
    it.
    If you want to use the latest Firefox with it's rapidly increasing
    major version number insanity you can just 'download it'
    (https://www.mozilla.org/en-US/firefox/new/), unpack it in your home
    directory and run it from there. If you create a symbolic link called
    firefox in ~/bin then it'll get run when you use the Firefox icon on the
    GNOME menu. (The GNOME menu entry is provided by
    /usr/share/applications/MozillaFirefox.desktop which doesn't specify a
    full path for firefox, so it'll run the first executable thing called
    firefox it finds in your $PATH. If you create ~/bin then that gets added
    to the start of your $PATH automatically, though you may need to log out
    and in before it's added to the $PATH than gets looked at when you click
    a menu entry)

    Alternatively, if you are willing to replace lots of packages provided
    with SLED with third party ones and deal with any issues that result
    from doing that, you could try adding 'this repo'
    (http://download.opensuse.org/reposit...ozilla/SLE_11/).

    Re: Problem with graphics


    Yes, I meant firefox, sorry about that.
    As for why I changed drivers, I tried to get minecraft working in
    browser at least, so I also updated my java to latest version, but that
    didn't help. Then I tried to install new drivers (however, they didn't
    solve the problem). And that's the only reason why I'm thinking about
    updating firefox, too.
    At some other forum, people suggested using open source ATI drivers,
    but I have no idea what they are and how to install them. Do you know
    whether they are good and ok to use?

    Re: Problem with graphics


    'Here' (http://en.opensuse.org/SDB:Radeon) you can find information
    about ATI open source drivers and there is a link to download source
    code. I think you'd rather compile it than install a binary package.

    Thanks, I'll read about them. By the way, how do I do some kind of
    backup in case something goes wrong? I'm relatively new to linux, so I'm
    not sure if I'd be able to fix it and I'd rather not lose my files.

    I could reproduce your Firefox behavior when flash is running (usually I
    have Flashblock plugin enabled). Have you tried to disable flash in
    browser or use some other browser (Epiphany, Google Chrome, etc.)?
