Nouveau won't work with gentoo-sources 4.4.1

[erikr]

Hi,

 

I ran into some strange problem when I upgrades kernel from gentoo-sources-4.4.0 to gentoo-sources-4.4.1. Suddenly nouveau stopped working. The procedure is that I copy the old .config, run make menuconfig and save the result. This has been working for a long time but not this time. When I downgraded to 4.4.0-r1 the video was back.

 

 

I got nothing in dmesg but I found this at the end of the /var/log/Xorg.0.log:

It also failed to generate a xorg.conf using X -configure. I normally have no xorg.conf as it normally works well without it.

 

Anyone else got the same problem or perhaps got it working?

No xorg.conf being used.
I always convert existing .config after importing to new kernel version.

make silentoldconfig

If I want to make configuration changes after conversion:

make menuconfig

Build kernel and modules, -j3 for my 2 core cpu:

make -j3

Install modules:

make modules_install

Install kernel:

make install

I don't use out-of-tree modules which would need to be compiled or initramfs.
If you need additional help please provide at least as much info as I have shared.

Hi,

 

Thanks for the post. The I managed to get somthing wrong and it is not a trouble for anyone (or at least not everyone) else. That is whay I posted here, to verify if this was a widespread problem.

 

I also ran into a lot of trouble with KDE5 and nouveau with frequent UI freezes so I went for the proprietary nvidia-drivers including kernel downgrade to 4.1.15-gentoo-r1 and since then everything have worked just perfect. As of now I will stick to "it's not broken so I will not fix it" and continue with the nvidia drivers :)
