[SOLVED] nvidia drivers

[pub01]

@AJSlye

You’ll need to install one of the bumblebee options, when in Hybrid mode the Intel chip is used for the system, and the Nvidia chip is used only when expressly assigned to an application.

Configure NVIDIA (non-free) settings and load them on Startup - Manjaro

Well, y510p is a strange hybrid, i don’t have intel videocard:)

inxi -G
Graphics: Card-1: NVIDIA GK107M [GeForce GT 755M]
Card-2: NVIDIA GK107M [GeForce GT 755M]

Same GT 755M, one bulit in, one in multibay.
But i used netrunner rolling since it’s released, with nonfree nvidia driver, the problem exists since the last update.
If nothing helps i’ll install the latest iso.

OK, that is not a hybrid then, that is a multiple GPU system and not exactly the same thing. A hybrid system would have two different GPU’s by two different manufacturers, so bumblebee or something similar would be required to switch cards. a multiple GPU system can use both GPU’s simultaneously and capable of spliting the screen and/or workload.

I understand, thank you!
Problem solved though, i found this thread:

https://bbs.archlinux.org/viewtopic.php?pid=1377358

I put this line to grub’s GRUB_CMDLINE_LINUX line:

rcutree.rcu_idle_gp_delay=1

Now everything is fine:)

Thank you AJSlye for your patience and help!

Is this what you are refering to:

On Linux >= 3.10 you may get a “fallen off the bus” error, if this happens you can either stick with an older kernel version (<= 3.9), or as a workaround add rcutree.rcu_idle_gp_delay=1 to your grub command line in /etc/default/grub, update-grub and reboot.

This is a known problem upstream and possibly an issue within the proprietary nvidia driver itself.

So my guess is that this is an SLI issue in-which one card is not initializing fast enough, I’m so glad you got it figured out now.

Yes that’s it:)
I didn’t meet this problem before, thats why i thought it’s because of the update, and i didn’t google hard enough:)
