Then, configure /etc/X11//nf the options of which will be combined with the package provided /usr/share/X11//nf to provide compatibility with this setup.
Resolume 5 and nvidia optimus install#
It does allow use of the discrete GPU and has (as of January 2017) a marked edge in performance over the nouveau driver.įirst, install the NVIDIA driver and xorg-xrandr. It also has notable screen-tearing issues unless you enable prime sync by enabling NVIDIA#DRM kernel mode setting, see for further information. The proprietary NVIDIA driver can be configured to be the primary rendering provider. Before turning off the Nvidia card after using CUDA, the nvidia kernel modules have to be unloaded first: Now when you start a CUDA application, it will automatically load all necessary kernel modules. All you need to do is ensure that the Nvidia card is powered on before starting a CUDA application, see Hybrid graphics#Fully power down discrete GPU for details.
You can use CUDA without switching rendering to the Nvidia graphics. Use CUDA without switching the rendering provider See Hybrid graphics#Fully power down discrete GPU. If your BIOS does not allow to disable Nvidia graphics, you can disable it from the Linux kernel itself. Some laptops only allow disabling of the discrete card, or vice-versa, but it is worth checking if you only plan to use just one of the cards. There should be an option to disable one of the cards. If you only care to use a certain GPU without switching, check the options in your system's BIOS. Note: All of these options are mutually exclusive, if you test one approach and decide for another, you must ensure to revert any configuration changes done by following one approach before attempting another method, otherwise file conflicts and undefined behaviours may arise. This package is being tested on Debian based system, but, like nvidia-xrun, it must work in all Linux systems. #Using nvidia-switch - Similar to nvidia-xrun, but not needing to change TTY, the switches will be done by login and logouts in your display manager.This package is experimental, and is currently being tested only under GNOME/GDM.
#Using NVidia-eXec - Similar to Bumblebee, but without the performance impact.#Using Env圜ontrol - Similar to optimus-manager but does not require extensive configuration or having a daemon running in the background as well as having to install a patched version of GDM if you are a GNOME user.#Using nouveau - offers poorer performance (compared to the proprietary NVIDIA driver) and may cause issues with sleep and hibernate.#Using Bumblebee - provides Windows-like functionality by allowing to run selected applications with NVIDIA graphics while using Intel graphics for everything else.It achieves maximum performance out of NVIDIA GPU and switches it off if not in use. #Using nvidia-xrun - run separate X session on different TTY with NVIDIA graphics.Since the 1.4 release AMD+NVIDIA combination is also supported. #Using optimus-manager - switches graphics with a single command (logout and login required to take effect).#Using PRIME render offload - official method supported by NVIDIA.Using both (use NVIDIA GPU when needed and keep it powered off to save power):.This utilizes the same underlying process as the optimus-manager and nvidia-xrun options, it should be utilized for troubleshooting and verifying general functionality, before opting for one of the more automated approaches. #Use NVIDIA graphics only - gives more performance than Intel graphics, but drains more battery (which is not welcome for mobile devices).#Use Intel graphics only - saves power, because NVIDIA GPU will be completely powered off.
