Geforce GT 740M - Nouveau errors

Are these errors which can be prevented (with nouveau), or is it just a matter of waiting for a driver improvement?

Re: Geforce GT 740M - Nouveau errors

I have the same issue on my ENVY 15t. This person here seems to have been been able to solve this:

It involves setting up bumble bee though, and I don't really want to set it up just yet, so I can't be the guinea pig for you, sorry! Let me know how it goes

In that article the Nvidia proprietary driver is used. I have tried it with the nouveau driver, but to no luck.

Yes I tried to install nouveau to see if it would satisfy the prompt but no avail. It's obvious from the Xorg log that nouveau is in the kernel, so you can't remove it. But you can blacklist it (cheap but whatever). Create this file:

/etc/modprobe.d/nouveau_blacklist.conf
---------------

blacklist nouveau

Then save and reboot. The nuisance message should be gone now. Also I log into xfce4 faster now which is awesome as hell.

Let me know if it works.

Hi rewrite,

My goals is to get rid of the error messages by using the opensource driver; I don't want to use the proprietary driver.

Umm.. Well like I explained in my second post, the proprietary driver doesn't fix anything anyway... I explained what you have to do to fix the error, did you blacklist nouveau?

EDIT: You mentioned you "tried" nouveau but it apparently did not work. Did you have intel-xf86-video running and tried nouveau in order to remove the error? Or did you already have nouveau and want to get rid of the error? If you have intel-xf86-video then blacklist nouveau and that'll solve the problem. If you want to use nouveau and not the intel driver, you'll have to mess with the kernel parameters. Let me know which option you want to take and I will help you.

Hi rewrite,

I tried to get a Bumblebee/Primus combination to work and for that I prefer to have both open source drivers enabled: intel and nouveau. Blacklisting does get rid of the nouveau error message, but also the possibility of having a working Optimus setup.
