    Re: Unity Laggy Ubuntu 11.10

    I've installed Ubuntu 11.10, 64bit version, on HP Compaq 6715s.
    My graphical card is ATI RS690M [Radeon X1200 Series].
    Just after the installation windows drugging was laggy. Then I've installed the packages: fglrx and fglrx-amdcccle. The windows drugging became smooth, but any graphical task, "glxgears" for example, fails with similar error:
    X Error of failed request: BadRequest (invalid request code or no such operation)
    Major opcode of failed request: 135 (GLX)
    Minor opcode of failed request: 19 (X_GLXQueryServerString)
    Serial number of failed request: 12
    Current serial number in output stream: 12
    Also, amdcccle fails with error:
    There was a problem initializing Catalyst Control Center Linux edition. It could be caused by the following.
    No AMD graphics driver is installed, or the AMD driver is not functioning properly.
    Please install the AMD driver appropriate for you AMD hardware, or configure using aticonfig.

    Re: Unity Laggy Ubuntu 11.10

    This issue has been my #1 problem with a lot of distros on my laptop. It became a lot worse with Unity though. And, in 11.10 the GUI is almost unusable. From googling, users reporting this is often using some kind of a mobile graphic chip. Mine is the Nvidia Quadro NVS 160M. Not exactly great, but the performance I get in Windows is light years better compared to Ubuntu 11.10. I would expect Ubuntu (and its siblings) to at least be on par.

    I have tried all the hacks to no avail. I have tried with and without proprietary drivers, but the open source version is, sorry to say; Crap.

    If I just sit idle and observe TOP - Xorg can use 50% of the CPU for about 10 minutes without me doing anything on the computer what so ever.

    To me this is a show stopper, and I am greatly disappointed. They really have to pay attention this. It has been a problem for many for a long time. Fancy features and innovative thinking is fine, but, make sure the basics are working first.

    I have the same problem on my T420 ThinkPad with SandyBridge graphics only (i5). System info in the settings even shows the probably correct video driver SandyBridge mobile.

    After trying to change the Sync to VBlank option in OpenGL, Unity 3D stopped working completely, I had to reset the settings to default.

    Re: Unity Laggy Ubuntu 11.10

    My 11.10 upgrade worked fine for more than a week, but after few updates yesterday the video lag started, I tried disabling options in Openggl etc etc with no luck in display lag. Any video play takes 100% CPU and still video tears a part frequently, it is very hard to watch at my browser when I do scrolling, and I type a sentence and stop, ubuntu takes maybe 0.5 secs to complete typing, I mean the test still coming even after I stopped tying. By the way I am using latest(as of now) ATI catalyst drivers for my HD4200 video card.

    maybe it's partly related to this Compiz CPU eating bug: https://bugs.launchpad.net/unity/+bug/803943

    at least I see this behaviour in my case too

    I had the same problem. I started using Ubuntu 2D from the login menu. My graphics card must just be poorly supported. Much better under 2D.

    Re: Unity Laggy Ubuntu 11.10

    Is there a way to disable unity and go to the normal desktop environment without having to install the Compiz software?

    I have a user base I would like to upgrade but they highly dislike the unity UI.

    Thanks.
