Pyrit Cuda Nvidia Optimus Power Drain

[max8126]

It might be worth noting that due to a bug, some Optimus laptop (that has customized N-card) will have problem recognizing the NV card. Upon loading nVidia's driver/dmesg, you'll see error "NVRM: failed to copy vbios to system memory."

A hack can be found here:https://github.com/Bumblebee-Project...novo/README.md

BTW, thanks for the awesome guide.

snafu777,

first of all thanks for the great job you did, and thanks to it i got pyrit successfuly working with Cuda, so i've managed to install well the new 304.51 drivers and so on, but what i can't get now is my system to work on Nvidia drivers permanently. When i go on System settings -> Nvidia X server settings and click on it i get error message saying:

"You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server."

If i do run the command : "nvidia-xconfig" as root i get the /etc/X11/xorg.conf doesn't exist it will be created, but after when i try to start X on the next session i can't do it till i don't remove the file /etc/X11/xorg.conf created.

my system is :

Samsung np-rc530
Graphic card: nvidia gt 540 M
Backtrack 5R3 64bit KDE

Thanks in advance,

Alex

i got everything working on my alienware m14xr2 laptop
pyrit gives me 1 cuda core + i7 @ 8407pmk
the optirun works fine + gears test

i can open nvidia settings, but get the error below

i get the error :
you do not appear to be using the nvidia x driver please edit your X configuration file (just run nvidia-xconfig ) as root and restart the x server

but there is no nvidia-xconfig file found only nvidia-settings
if i do modprobe nvidia . i get fatal error inserting nvdia (lib/modules/3.2.6/updates/dkms/nvidia.ko) no such device

my system is :
alienware M14X R2
Graphic card: nvidia gt 650 M 2gig
Backtrack 5R3 64bit GNOME

Thanks in advance,

Sorry I don't really respond like I used to on here. I pissed off one of the moderators a while back, and as you can see I am "Permanently Moderated".

That aside, the guide was never meant to make it the nvidia card work from the true GPU standpoint. It was only meant to enable the user to be able to
1) Control the power drain from having two GPUs

2) Enable them to use cuda

For anything else, I never really bothered because when I want GPU eye candy I stick with Linux Mint or Windows..... Remember, BT is not for everyday usage =)


I am glad to see that people truly enjoyed the guides I have made on here. Maybe one day again I'll get back into writing on here again.

Thanks for the support =)

I am always happy to talk hacking.
