Re: Loading a web java applet with optirun64/bumblebee

  Thread Previous • Date Previous • • Thread Next
The way I understand it, this technique is essentially using a "remote desktop" technology to access rendered output that would otherwise not be displayed on a monitor. Basically, "run this program and display it on 'this' screen... now copy 'this' screen to the current display." And since it is being addressed this way, only whole windows can go.
Now, there are video overlay techniques that have been used for a very long time that essentially uses dedicated hardware to render video and then passes it through the display hardware through a rectangle of specified size, shape and location. What we need is THAT. If we could use the same means as V4L to pipe the rendered graphics from memory to the active display, then this jpeg stream will not be needed and we should see an even better performance increase.
All of this likely needs lower level work in the X.org project. I recently looked over at what they are doing at X.org about this and so far, it seems like no notice of the hybrid graphics/optimus problem has been taken.
This optirun/bumblebee thing is "the way forward." I have little doubt about that. But it needs to move into the X.org project in some way. This is beyond some clever scripting and utilization of existing technologies which I consider to be "proof of concept." And as proof of concept is concerned, I would say it is proof positive.

Héctor,
I suspect vglrun only works for stand alone apps as opposed to embedded windows as used by plugin, so perhaps this is not possible? I don't have much knowledge of vgl before using bumblebee so I can't help much at this I'm afraid.

Steve

@Bilal Akhtar: I tried installing Google Chrome and the running it with optirun64. It worked fine, however I can't activate OpenGL mode in Runescape anyway. Can you activate OpenGL mode? Because software mode isn't that good.
@Stephen Brooks: Your solution seems to be what I was looking for, but then again, I don't know if the game can't detect that the Nvidia card is running because it defaults to software mode, it doesn't allows me to use OpenGL. Anyway, I think I got something wrong with bumblebee. I will Investigate further to check this out. 

Thanks for your help.

    Hi,

        I suspect you need to wrap the java_vm binary.  I used a
    similar trick in the past to run it via aoss.  I'm not on my
    laptop at the moment so this is all untested, might just work
    can't think why it wouldn't.

    Find and change to your java_vm directory ("locate java_vm"
    should help)

    For me is:

    cd /usr/lib/jvm/java-6-sun/jre/bin

    sudo mv java_vm java_vm_orig

    sudo touch java_vm
    sudo chmod a+x java_vm
    sudo vi java_vm

    Insert and save:

    #!/bin/bash
    exec optirun64 /usr/lib/jvm/java-6-sun/jre/bin/java_vm_orig

    Probably need to restart your browser to cleanly exit any
    currently running java_vm.  Let us know if it works :)

    Regards,
    Steve

    Nope, I was thinking the same, but I can't activate the OpenGL
    mode, it remains on Software mode wihich works kind of laggy. Or
    perhaps the game doesn't supports OpenGL with VirtualGL. Just
    wondering. In Windows I fixed that by adding Java to the list of
    programs that runs with Nvidia, nonetheless in Linux I can't do
    that since the Firefox plugin seems to call directly the java
    executable and doesn't allow any launcher/shortcut that calls
    optirun and Java.

        Wont launching the browser with optirun work????

        *Emne: *[Hybrid-graphics-linux] Loading a web java applet
        with        optirun64/bumblebee


        One of my primary objectives for enabling the NVIDIA card on
        Linux is to play a Java-based online game named Runescape.
        The game has HD graphics which only run well with the NVIDIA
        turned on, however I'm currently unable to call Java with
        optirun64. I think this is because Firefox uses the Java
        plugin as intermediary and so I can't create a shortcut or
        launcher which calls optirun and Java in order for the later
        to be accelerated. Any idea on how to call Java using optirun?
