You accidentally listed the same command for installing Nouveau as with installing Nvidia. You have nvidia in both commands.

[YFDogan]

Thanks brother.

[Matthias19281]

How can I switch from nvidea drivers (that only make trouble on my system) to nouveau?
Extra information:
Nvidia GTS8800 512MB
Asus P5QE (if relevant)

[YFDogan]

Remove Nvidia:

Code: [Select]

sudo mhwd -r pci video-hybrid-intel-nvidia-bumblebee
And install Nouveau

Code: [Select]

sudo mhwd -i pci video-hybrid-intel-nouveau-bumblebee

[Roland]

You don't have to remove the old nvidia driver Just execute the last command posted by YFDogan.

[handy]

Do you want this one on the wiki YFDogan?

I'm not familiar with the problem, is it going to go away soon or be around long enough that the wiki would be the right place for it?

[YFDogan]

This depends on Optimus. May be this questions answer may given by Philip.

[Khazrak]

After a fresh install and update (which package-query and yaourt requires fix-around) I now want to switch to the non-free nvidia drivers.
So I write:

Code: [Select]

sudo mhwd -i pci video-hybrid-intel-nvidia-bumblebee
And it gives the error:

Code: [Select]

Error: config 'video-hybrid-intel-nvidia-bumblebee' conflicts with config(s): video-hybrid-intel-nouveau-bumblebee
I've tried to remove the nuoveau drivers and installing the nvidia and doing the switch-command. After rebooting the system has a major breakdown and needs reinstalling.

Any suggestions?

[YFDogan]

Try with force option:

Code: [Select]

sudo mhwd -i pci video-hybrid-intel-nvidia-bumblebee -f

[Khazrak]

Try with force option:

Code: [Select]

sudo mhwd -i pci video-hybrid-intel-nvidia-bumblebee -f

Same error 

[YFDogan]

Try with force option to remove your current driver friend.

Hello,

I am confused by this post, excuse my ignorance for asking but when I start up, Bumbleebee C Daemon is enabled which I thought enabled the Nvidia card without any further action.  Is this not so or do I have to run the scripts as advised in this post?

Any clear advice much appreciated.

For clear advice, you should post clear question, no
Which scripts are you talking about?

If bumblebee daemon is enabled on startup

Code: [Select]

sudo systemctl enable bumblebeed.service
 and

Code: [Select]

mhwd -li lists your card, then you dont need to do anything else unless you are having problems.

If you are having some problem ,make a seperate thread for it.

Hi
I'm a linux newbi and I installed Manjaro on my Asus Pro64J and i love it. Manjaro automatically installed Bumblebee for me but the optirun and primusrun commands doesn't work. So I installed the "video-hybrid-intel-nvidia-bumblebee" driver and tried again:

Code: [Select]

>> optirun blender
[  788.331665] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NVIDIA(0): Failed to assign any connected display devices to X screen 0

[  788.331711] [ERROR]Aborting because fallback start is disabled.

Code: [Select]

>> primusrun blender
primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) NVIDIA(0): Failed to assign any connected display devices to X screen 0When i start the nvidia-settings it tells me to run nvidia-xconfig, but that changes nothing...
What do i have to do now to use my nVidia graphics for blender or playing games?
I currently use xrandr to use a hdmi connected display next to my laptop display if that helps.
Thank you
