    Default Linux Hybrid Graphics Will Be A Mess For A While

    Phoronix: Linux Hybrid Graphics Will Be A Mess For A While

    Most of you know this already, but: hybrid graphics, the technology concept of having dual GPUs (generally a low-power IGP and a high-performance discrete GPU) and being able to seamlessly switch between them depending upon load and battery life, is a mess under Linux. It will continue to be a mess for the near-term...

    Maybe you should be going to the Fedora or Redhat conferences. You would probably get more info from people working on the solutions rather than the Ubuntu "It won't be supported until Redhat fix it" lines we get - same goes for your power bug

    Well generally we don't have specific conferences to deal with upstream issues, or sit around patting each other on the back talking about something that nobody in the room is qualified to discuss. For RH/Fedora devs we just go to upstream conferences and do the work in public. Also those conferences generally try to provide better quality coverage than phoronix, say via lwn.

    It's funny that Michael never reports the company I work for in Ubuntu articles :-), but other work I do gets mentioned as Red Hat does something, when really Red Hat is in no way "doing" it. It just happens to be a project I want to do and RH makes sure I can do.

    some of it is, the buffer sharing and kernel drivers for USB devices,

    the X server stuff not so much since its in the X server. However any solution replacing X in a desktop env will have to consider the issues, which I'm not sure anyone has done so far.

    thanks

    i seem to recall that wayland people have mentioned something about multi GPU and similar stuff in the mailing list and also that there has been discussions with graphic devs but that was a looong time ago

    For those not keeping track, Ubuntu is now supposed to be the go to operating system for desktops, laptops, servers, phones, tablets, X86, ARM, the cloud, new stuff, old stuff (long term support), developers, translators, proprietary software companies and who knows what else. (Note exclusion of power users.) As they say, jack of all trades and master of none.

    Perhaps RH should offer a free-form survey for users to bitch about graphics on Linux.

    I'm sure Michael would report that with glee.

    John

    p.s. Thanks for all your work.

    I want to know about optimus.

    I don't want/need the Geforce graphics. what happens when I run linux in an optimus enabled laptop?
    Does the normal intel graphics driver work?
    Is there any way of disabling the nvidia GPU, or is it disabled by default?

    Thanks in advance :-)

    I think Bumblebee-project (not just Bumblebee) is more madured than Ironhide, at least it has a comunity behind it and is not maintaned just by one person.

    I'm now running a optimus laptop with bumblebee installed, and it works.

    @grigi: default the Intel is used and the nvidia driver (or nouveau) is not loaded. But the card still uses energy and you need to turn it off manually or with an application with the right acpi calls.
