I don't use Ubuntu/Debian but I do use Linux-rt + nVidia, in all of my H/W. So i thought i would clarify a point or two; last This above patch only works for Nvidia driver < 325.xx ... 1. For Nvidia's newest drivers ~ you need my nvidia325xx-rt patch; http://sourceforge.net/projects/l-proaudio/files/nvidia-325xx-rt.patch/down… (for me, this patch works fine on 3.8-rt and 3.10-rt. haven't tested anything older... I'm sure it's fine). When building the kernel module (don't know where this is done in Debian/ubuntu) you must ignore the PREEMPT_RT check in nvidia's installer, something like this; " make IGNORE_PREEMPT_RT_PRESENCE=1 SYSSRC=/usr/lib/modules/"${_kernver}/build" module " 2. I've also made available a patch for 319.32, patched for kernel 3.10 support (which then can be patched with the old rt patch, above "patch-3.0-rt-nvidia.patch"). - This is mainly for people who've experienced regressions with the 325xx nvidia driver, Patch is here; http://sourceforge.net/projects/l-proaudio/files/nVidia-319.32_lk310.patch/… I've also started a thread @ nvidia's dev portal about nvidia-rt; https://devtalk.nvidia.com/default/topic/572468/linux/nvidia-325-15-linux-r… There aren't specific distro instructions, but a general "run down", instead. I don't know how different distros package nvidia, so it's beyond my own scope...and Since, i only use Archlinux, it is the only distro that i personally am concerned with. + anyone can see how Archlinux handles nvidia-rt by either reading through Arch's PKGBUILD in AUR; https://aur.archlinux.org/packages/nv/nvidia-rt/PKGBUILD ... then find out how to made your own distro apply what is needed. cheerz Jordan
