[solved] problem changing to nouveau, gtx970 not supported?

sbt1 · 2016-01-15 11:29:58

Hi, I want to change the graphics driver for my GTX 970 from nvidia to
nouveau (context: https://bbs.archlinux.org/viewtopic.php?id=207391). I installed the required
packages according to the wiki, then I did the following:

1. Change

/etc/X11/xorg.conf.d/20-nouveau.conf

from

Section "Device"
    Identifier "Nvidia card"
    Driver "nvidia"
EndSection

to

Section "Device"
    Identifier "Nvidia card"
    Driver "nouveau"
EndSection

2. Change

/usr/lib/modprobe.d/nvidia.conf

from

blacklist nouveau

to

#blacklist nouveau

But when rebooting it doesn't work, here is what I observed so far:

1. I receive just a blinking cursor, no X server is started. The cursor is pretty small though, as if modesetting has worked and the resolution was changed. (I have autologin in my DM activated)

2. When changing to another tty (with ctrl-alt-f1 for example) it also has the right resolution (in contrast to when the nvidia driver is used, where everything is way too big) and I can login there.

3. When going to another tty it says above the username prompt:

(...)nouveau(...)gr: failed to load fecs_inst
(...)nouveau(...)DRM: Pointer to flat panel table invalid

4. When trying startx some error messages are printed and it does not start. I am not able to pipe these to a file though (startx > error.txt does not work), but in

~/.local/share/xorg/Xorg.0.log

it says this:

Line that rose my suspicion:

[   131.435] (EE) Unknown chipset: NV124

But according to this: https://www.phoronix.com/scan.php?page= … px=MTg4NTg it should work (at least at ubuntu, but what ubuntu does should not be a problem for arch?). Or does Arch Linux have a nouveau version in its repositories that does not support the GTX 970?

Additional info:

- There is no nomodeset in my boot parameters
- I use lightdm as display manager

Any help / hint is highly appreciated, thank you very much!

EDIT: I just found this: https://bbs.archlinux.org/viewtopic.php?id=205282

So in short: no GTX 970 with nouveau at the moment, right? But how did this dude with Ubuntu get it to work?

If you look at the chipset numbers, the one used in the phoronix article is lower than yours. So your card might be a rebrand with a newer chip, and that newer chip isn't supported by Nouveau.

I'm going to post in your original thread why it didn't work with the nvidia module.
