Product: Fedora Documentation https://bugzilla.redhat.com/show_bug.cgi?id=901500 Bug ID: 901500 Summary: GPU offload (dynamic hybrid graphics) support Product: Fedora Documentation Version: devel Component: release-notes Severity: medium Priority: unspecified Reporter: TomasM@xxxxxxxxx Created attachment 682312 --> https://bugzilla.redhat.com/attachment.cgi?id=682312&action=edit sample glxinfo output (with DRI_PRIME set and unset) Fedora 18 supports GPU offloading for many systems with dynamic switchable graphics support (AMD PowerXPress, NVIDIA Optimus or similar). Setting DRI_PRIME=1 will render applications with the discrete graphics card on supported hardware. Is this something that should be in the release notes? - AFAIK Fedora 18 is the first distro released with dynamic gpu offload support - this is a big deal for most laptops with two graphics cards, as the more powerful card is just a power drain for most Linux users at the moment. - As per IRC discussion with randomuser, I haven't found upstream docs on how to actually enable this functionality and think it would be useful to document somewhere. I can pull snippets from kernel, Xorg, libXrandr and mesa changelogs to confirm all of this, but am hopeful a graphics dev (this is largely David Airlie's work) can verify this instead. Dave has come across a laptop model which doesn't work with the release-day code; I'm not sure if his warrants some ambiguity or a technical disclaimer for 'supported hardware'. -- You are receiving this mail because: You are the assignee for the bug. -- relnotes-content mailing list relnotes-content@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/relnotes-content
