The NVIDIA Linux driver doesn’t handle the VRAM sharing with the system RAM. What I’m exactly referring to is this: Windows 10 Task Manager in GPU section As can be seen, there is the “Dedicated GPU memory” and the “Shared GPU memory” that is actual system RAM but shared with the GPU, so in case t…

I’m not sure if I’m missing something here but I believe in order to use unified memory you must load the nvidia-uvm kernel module. CUDA Installation Guide for Linux The installation instructions for the CUDA Toolkit on Linux. My understanding is the path o…

Thanks. I will try it later if I can do it.

VRAM management is simply, really, really bad with Nvidia on Linux. It doesn’t matter if you enable this or not; it does not help, and Nvidia isn’t doing anything about it; everything just becomes a lagfest or outright crashes if you are running out of VRAM.

Well, I tried it and it didn’t work at all. It was kinda tricky to do but I basically unloaded the nvidia modules and I loaded them again using /usr/bin/nvidia-modprobe --unified-memory --create-nvidia-device-file=1(with modeset on for the nvidia_uvm module) Nothing changed at all.

I would try with the the open source driver if you haven’t already. There was something about needing that, a 6.1x kernel w/ HMM (Heterogeneous Memory) ‘CONFIG_HMM=y’ and enabling that in the module when loading. The goal post on this so to speak keeps moving. @Alzt may be right in that it’s more …

I decided to test the 555 driver because of Explicit Sync it works really well on Wayland and the Desktop animations are finally smoth (after years of waiting…) but the VRAM management is still really bad and it’s worse on Wayland because now if the game/program hits the VRAM limit of the card, the w…

gtx 1650 4gb vram nvidia, why cant you just add shared vram, its going to make linux ligher then windows, please just add it, please i really need it i cant afford new gpu and on windows i get over 60fps and on linux i only get 20-30fps becouse of Non-existent shared VRAM

I have the same issue with my RTX 3070 and the 555 driver. Playing games causes xwayland to crash with [drm:nv_drm_gem_alloc_nvkms_memory_ioctl [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to allocate NVKMS memory for GEM object [drm:nv_drm_gem_alloc_nvkms_memory_ioctl [nvidia_drm]…

I have a NVIDIA 2080ti with NVIDIA 555.58.2 and same problem when i run game with a high VRam usage. XWayland crash with same error

open source driver if you haven’t already

I have a 1060 so it’s over for me. I have a laptop with a 3070 but is not worth trying because I don’t even play on it.
