EndSection Maybe it is possible to use the value "40" instead of "30" in order to see if there is some difference... To achieve the latter, add the following systemd service (if using bbswitch): /etc/systemd/system/nvidia-enable.service [Unit] Description=Enable NVIDIA card DefaultDependencies=no [Service] Type=oneshot ExecStart=/bin/sh -c 'echo ON > /proc/acpi/bbswitch' [Install] WantedBy=shutdown.target Then enable the Both parts are included in a single package.

Although the Intel CPU idling method recently was introduced as the default CPU idling method for i5 and i7 CPUs (versus using ACPI CPU idling) is the root cause here. EndSection Note: To prevent DRI from loading, commenting may not be sufficient, and you will need to the following instead. 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 Content is available under GNU Free Documentation License 1.3 or later unless otherwise noted.

For example, if the symlink should point to the number 5 item in the list, run: eselect kernel set 5 Required Kernel Settings Note: If you built your kernel with genkernel, I've never looked into the ebuilds to see how they manage it, but the on-screen output shows lines saying things like "registering self with module-update" or words to that effect.
Click on the "Enable Overclocking" checkbox and read and accept the license agreeement. For instance the default value is 60mb which is in fact 64mb - 4 = 60 so the value set is 60. Substitute

(Nevertheless, the other features of Bumblebee do work on some Gentoo Nvidia Optimus My suggestion is to crank this up to 100. Gentoo Nouveau First follow the X Server Configuration Guide and set VIDEO_CARDS="nvidia" in /etc/portage/make.conf.
If you don't have PAT support you may experience unstable performance, crashing even failure enabling this so be careful with these options. For proprietary drivers like nvidia.ko, it doesn't work quite the same. There is no known alternative framebuffer for (U)EFI systems. However, bbswitch is for Optimus laptops only and will not work on desktop computers. Gentoo Disable Nouveau

MSI interrupts can be disabled via the NVIDIA kernel module parameter NVreg_EnableMSI=0. If you do need to change some features for the Intel module, a workaround is to merge /etc/X11/xorg.conf.d/20-intel.conf to /etc/X11/xorg.conf.
This can be achieved by pressing Ctrl + Alt + Backspace. If you enjoy this, checkout KGDB.;-) (If you really want, you can also export the init startup info printed on console, but it's a one way deal. In this case, be sure to remove the /etc/X11/xorg.conf or .../20-nvidia... In this case simply re-emerge the kernel and nvidia kernel module.
Reboot and enter the BIOS, then find the MTRR settings (probably under "CPU Settings"). Check lspci output to confirm that the system has a nVidia graphics card installed and detected. Remember to run update-modules after modifying this file, and bear in mind to reload the nvidia module before the new settings take effect. NVIDIA Optimus - Configure a system to use closed-source drivers for hybrid graphics (modesetting).
The integrated GPU manages the display while the dedicated GPU manages the most demanding rendering and ships the work to the integrated GPU to be displayed. Enable OpenGL/OpenCL To enable OpenGL and OpenCL though the device, run: root #eselect opengl set nvidia root #eselect opencl set nvidia Make sure that the Xorg server is not running during Once the installation has finished, run modprobe nvidia to load the kernel module into memory.
