ne fonctionne pas "vgaswitcheroo/switch"

diabolik62

bonjour,
Je come'm 52 ans et je suis italien, je viens d'installer fedora20 et déjà j'ai des problèmes, je l'espère, de trouver du soutien pour mes gros problèmes, en particulier celles liées à

cat /sys/kernel/debug/vgaswitcheroo/switch
No such file or directory

J'ai installé fedora20 mate,

Bonsoir,

diabolik62

Bonsoir,
merci pour votre réponse, j'ai suivi le guide que vous avez accédé, aujourd'hui j'ai essayé à nouveau d'installer de nouvelles mises à jour ne yum update, mais vgaswitcheroo ne fonctionne pas, quelqu'un peut-il m'aider?
si vous avez besoin d'autres commandes, je suis toujours disponible
merci

Edouard_le_homard

vire vgaswitcheroo et utilise bumblebee pour switcher entre la carte intel et la nvidia

Testing Bumblebee

To verify you are now using the NVIDIA driver, run the glxgears demo (from mesa-demos):

optirun glxgears -info | grep "GL_VENDOR"

You should see some gears rotating. In the terminal you should see "GL_VENDOR = NVIDIA Corporation" or something similar.
Primus

For speed imrovements you can use primus. Primus is a shared library that provides OpenGL and GLX APIs and implements low-overhead local-only client-side OpenGL offloading via GLX forking, similar to VirtualGL. It intercepts GLX calls and redirects GL rendering to a secondary X display, presumably driven by a faster GPU. On swapping buffers, rendered contents are read back using a PBO and copied onto the drawable it was supposed to be rendered on in the first place. Currently primus requires the NVIDIA proprietary drivers.

Install primus:

#yum -y install primus

If you want to run 32 bit apps on your 64 bit system, then also install:

#yum -y install primus.i686

Testing primus

Open up a terminal and run:

PRIMUS_VERBOSE=2 optirun -b primus glxgears -info

If primus is working properly, you should see "primus: profiling:" messages every so often in the terminal you ran it from.
How to use Bumblebee

General Usage:

optirun [options] <application> [application-parameters]

If you installed primus, then you can use the following command to take advantage of it:

optirun -b primus <application> [application-parameters]

Start Windows applications:

optirun wine <windows application>.exe

with primus:

optirun -b primus wine <windows application>.exe

By default, primus renders up to 60 fps. To render more frames per second:

vblank_mode=0 optirun -b primus <application> [application-parameters]

In practice this will probably only waste power, as most screens do not display more than 60 frames per second.

You can always run "man optirun" for more information.
