Check lspci output to confirm that the system has a NVIDIA graphics card installed and detected.

KERNEL Disable AMD Secure Memory Encryption (SME) support Processor type and features -> It should say that direct rendering is activated: To test the NVIDIA card, fire up X and run glxinfo, which is part of the x11-apps/mesa-progs package. This tool allows the user to monitor and change graphical settings without restarting the X server and is available through Portage as part of x11-drivers/nvidia-drivers with the tools USE flag set. Then, run emerge -uD -newuse to rebuild the applications that benefit from the USE flag change. There are also some applications that use the nvidia USE flag, so it might be a good idea to add it to /etc/portage/nf. See the VDPAU article for enabling VDPAU support.

GeForce 8 series and later GPUs do come with VDPAU support which superseded XvMCNVIDIA support. Add in xvmc in the USE variable in /etc/portage/nf or add it as USE flag to media-libs/xine-lib in /etc/portage/e. Some tools, such as media-libs/xine-lib, use a local USE flag called xvmc which enables XvMCNVIDIA support, useful when watching high resolution movies. Note that users will be able to run X without permission to the DRI subsystem, but acceleration will be disabled. If not, double check the kernel configuration so that this support is enabled: If genkernel all was used to configure the kernel, then everything is all set.

The hardware warranty will most likely be void, Gentoo's maintainers cannot begin to fix the issues since it's a proprietary driver that only NVIDIA can properly debug, and the kernel maintainers (both Gentoo's and upstream) will certainly not support proprietary drivers, or indeed any "tainted" system that happens to run into trouble. Do note that neither the nvidia-drivers maintainers nor NVIDIA will support this situation.

#UBUNTU CHECK VIDEO DRIVER PATCH#

If absolutely necessary, then it is possible to use the epatch_user command with the nvidia-drivers ebuilds: this allows the user to patch nvidia-drivers to somehow fit in with the latest, unsupported kernel release. NVIDIA usually takes a few weeks to prepare a new proprietary release they think is fit for general use. When a new, incompatible kernel version is released, it is probably best to stick with the newest supported kernel for a while. Even after managing to patch things up to have things seem to work nicely, the user still risks that running nvidia.ko in the new, unsupported kernel will lead to data loss and hardware failure. When the internal ABIs change, then it is not possible to merely fix the "glue", because nobody knows how the glue is used by the proprietary part.

For proprietary drivers like nvidia.ko, it doesn't work quite the same. For open source drivers, especially those distributed with the kernel, these changes are nearly trivial to fix since the entire chain of calls between drivers and other parts of the kernel can be reviewed quite easily. These all need to work nicely together as otherwise the user might be faced with data loss (through kernel panics, X servers crashing with unsaved data in X applications) and even hardware failure (overheating and other power management related issues should spring to mind).įrom time to time, a new kernel release changes the internal ABI for drivers, which means all drivers that use those ABIs must be changed accordingly. The kernel module ( nvidia.ko) consists of a proprietary part (commonly known as the "binary blob") which drives the graphics chip(s), and an open source part (the "glue") which at runtime acts as intermediary between the proprietary part and the kernel. It builds as a module, so the kernel must support the loading of kernel modules (see below). If the system has a card that needs these drivers then it is recommended to use the nouveau driver.Īs mentioned above, the NVIDIA kernel driver installs and runs against the current kernel. Note that Gentoo does not provide legacy drivers before version 390.xx. 6.14 ERROR: Kernel configuration is invalid.įILE /etc/portage/e/ffmpeg Adding the -video_cards_nvidia USE flag to ffmpeg media-video/ffmpeg -video_cards_nvidia.6.13 Distorted white lines during early boot.6.12 udevd using 100% of the CPU, X server failed to start.
