    Re: switchable gpu

    You are not the only one with this problem, switchable graphics and linux (or better say, xserver) is still not very nice.

    http://ubuntuforums.org/showthread.php?t=1861541

    And according to this bugreport: https://bugs.launchpad.net/ubuntu/+s...er/+bug/813809 it is not a very high priority issue so if you want to use an ATI/Intel switchable graphics solution you have to stick to the opensource drivers and use the vgaswitcheroo command to disable the ATI and use the Intel. The opensource AMD/ATI drivers are not to fast but at least they are stable.

    For the switcheroo commands look here:

    Re: switchable gpu

    I also have a switchable GPU laptop (HP Envy 14 beats) but I'm not even able to run ANY openGL applications.

    As soon as I attempt to open an application that uses openGL it just instantly closes on me. (This includes even basic games like gl-117)

    Any help on this?

    edit: Here is where gl-117 dies, I think this is probably useful info
    Code:
    X Error of failed request:  BadRequest (invalid request code or no such operation)
      Major opcode of failed request:  155 (GLX)
      Minor opcode of failed request:  19 (X_GLXQueryServerString)
      Serial number of failed request:  13
      Current serial number in output stream:  13
    Segmentation fault
