Nvidia drivers and Optimus on laptop ?

[Dupo]

Hi,

I installed nvidia drivers from Cauldron repository (331.38). But when I restarted the computer, the system crashed (glx render problem). The computer have Optimus technology. I guess if I want to use proprietary nvidia drivers and the nvidia card on the laptop, I must use Bumblebee + primus + libvirtualgl + bbswitch ? Or must I desactived OpenGL ?

Someone can give me more informations about it ? Could I use nvidia "tools" (nvclock, dkms-nvidiabl, nvidia configuration tool, etc.) ?

Thanks.

Note: I see that bumblebee + primus + dkms-bbswitch + dkms-acpi_call are available in russian repository for Mageia 4. Do I need others files, or these files above are only necessary ?

Hi,

I followed the Mageia wiki tuto about bumblebee, but I've got a problem. When I try to launch Optirun (eg. optirun glxgears), the system tell me it :

Code: Select all

[Error] Cannot access secondary GPU - error : [XORG] (EE) NVIDIA(0) Failed to initialize the NVIDIA kernel module. Please see the
[Error] Aborting because fallback start is disabled.

I installed the last nvidia drivers from Cauldron Mageia repository (331.38), I defined user in bumblebee group ans video group.
I modified /etc/bumblebee.conf :

Code: Select all

Driver=nvidia   KernelDriver=nvidia-current   TurnCardOffAtExit=true

I added in /etc/modprobe.conf :

Code: Select all

nvidia-current && bumblebee

I blacklisted the Nouveau driver in blacklist-compat.conf
I'm come back to intel driver.

Do you know what's wrong ?

Thanks for your help.

Greetings.

Note: How works dkms-bbswitch ? is it automatically ?

Well it would maybe be a good idea to get the nvidia driver working in the first place (that is disabling hybrid/Optimus mode and only using discrete graphics if your BIOS/UEFI allows for that) before trying fancier stuff.

Hi,

@doktor5000: I can't disable hybrid/Optimus mode in my Bios/UEFI (it doesn't exist). I try to use only the discrete graphics (NVIDIA) with the nvidia drivers, but it doesn't work. That's why I try to use Bumblebee and/or Primus.

But each time, I've got the error message above.

Did you have a look in /var/log/Xorg.0.log after X server fails to start? What does it say?

[Dupo]

Hi,

here's the part of the result from Xorg.8.log :

I changed "ConnectedMonitor" "DFP" to "CRT", always the same error.
I changed the screen resolution, always the same error.

I use Cinnamon desktop. Only Nvidia 331.38 drivers installed from Cauldron repository. Kernel 3.12.8 installed.

What does

Code: Select all

dmesg

or

Code: Select all

journalctl -a --no-pager -n250

say at the time, as suggested in Xorg.0.log?
The same goes for /var/log/Xorg.8.log

Hi,

as I see in dmesg, it launch Nouveau. But, I uninstalled Nouveau driver (xorg-video-nouveau and xorg-video-nv driver).
And I backlisted Nouveau.

Here's the part I see in dmesg :

Thanks.

Where does it say that it launches nouveau? And what does lsmod say?

[Dupo]

Hi,

it launch Nouveau before plymouth.

I launched dmesg with bbswitch and with nvidia, here's the results :

Code: Select all

$ dmesg | grep bbswitch

$ dmesg | grep nvidia

NVRM: nvidiafb, or rivatv was loaded and obtained ownership of


Note: Ok, after some research, I found what's the problem. I will tell you later.
Optirun seems to work, but I've got an other error with glxspheres :

Code: Select all

$ optirun -vv glxspheres

Some people said to reinstall libgl1-mesa-glx and/or mesa. Others said to check VGLTransport=proxy in /etc/bumblebee/bumblebee.conf

What do you think about that error ?

Thanks.

Greetings.
