Fedora 23 NVidia issues

[arthururbano]

I installed Fedora 23, now my kernel got updated to 4.2.1-300 and my Nvidia GT-630 stopped to work.
Anyone can help me here, please?

I too am having various issues with Nvidia in F23.

I uninstalled the nvidia drivers and installed nouveau. I am now able to run gnome, but not KDE (Plasma).

nvidia drivers don't work with kernel 4.2 because ABI version is not good :

Xorg.0.log

The Linux kernel and Xorg are completely separate items.
The Nvidia driver works perfectly fine with the 4.2.x kernels.

What the Nvidia driver doesn't currently work with is the pre-
release Xorg 1.18 versions that are currently being pushed out
in F23. Downgrade to the 1.17 version and prevent it from
updating until Nvidia releases a new driver that supports the
new ABI, which will probably be within a few weeks.

Using IgnoreABI is also not a working solution this time around.

Thank for your explanation Vallimar.

I attempt to downgrade to 1.17 version, but but there are a lot of dependencies, I prefer stay here and see for new nvidia drivers with support for the new ABI..

Is the nouveau driver reliable enough under F23?

I'm still running F22 and I use the proprietary nVidia solution only because of the performance increase and lesser heat-up issues. However, there are some graphical glitches and since I don't game, I would rather go back to the nouveau driver .

I'm worried that when Wayland kicks in for good, nVidia will have to take action and adjust the drivers or it will only support the 'legacy' X server .

I have had same problems for a week now.
I was only able to run LXDE with some trick I already forgot, because later today when I rebooted, I was not even able to run X with nouveau-driver:

[ 381.350] (II) LoadModule: "nouveau"
[ 381.351] (II) Loading /usr/lib64/xorg/modules/drivers/nouveau_drv.so

[ 381.354] (EE)
Fatal server error:
[ 381.354] (EE) no screens found(EE)

Any idea what is the reason for that error with nouveau?
I had nouveau kernel-driver loaded and nvidia kernel-driver not loaded.

-ignoreABI indeed does not help to run nvidia.
BTW, where one should put that -ignoreABI in Fedora, if Xorg is wanted to run with that option?
I ended up doing this to test, because I couldn't figure out how else it could be done:

# mv /usr/libexec/Xorg.wrap /usr/libexec/Xorg.wrap.rpmorig

# cat >/usr/local/bin/Xorg.wrap <<ENDHERE
#!/bin/sh
exec /usr/libexec/Xorg.wrap.rpmorig -ignoreABI
ENDHERE

# chmod ogu+rx /usr/local/bin/Xorg.wrap

# ln -s /usr/local/bin/Xorg.wrap /usr/libexec/Xorg.wrap

But as said, it does not help. gdm and X won't crash, but won't work either. Only black screen.

So, I ended up downgrading Xorg:

# dnf --showduplicates --allowerasing --releasever=22 downgrade xorg-x11-server-Xorg
...
# uname -a
Linux myhost 4.2.2-300.fc23.x86_64 #1 SMP Wed Sep 30 01:36:26 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
# rpm -q xorg-x11-server-Xorg
xorg-x11-server-Xorg-1.17.2-2.fc22.2.x86_64

Now gdm and GNOME works with nvidia driver.

Should I do something now to prevent Xorg-packages to be auto-upgraded with dnf update?

Any ideas how?

I tried this, but it didn't work.

# cat > /etc/dnf/protected.d/xorg-x11-server-Xorg.conf <<ZZZZ
xorg-x11-server-Xorg
ZZZZ
# chcon system_u:object_r:etc_t:s0 /etc/dnf/protected.d/xorg-x11-server-Xorg.conf

Now already three times with "dnf -y update" also those xorg-packages are auto upgraded to xorg-x11-server-Xorg-1.18, which will broke gdm and X next time they are started.

I always need to downgrade manually.

How to enforce or protect it wouldn't upgrade xorg-x11-server-Xorg and related packages?

Edit:
Later I found, having this in /etc/dnf/dnf.conf works:

cat >>/etc/dnf/dnf.conf << _DNF
exclude=xorg-x11-server-Xorg
_DNF

It then refuses to upgrade several packages which are related to Xorg:
"Skipping packages with broken dependencies:"

[joncr]

The way I keep packages from updating is adding them to an "exclude=..." line in /etc/dnf/dnf.conf.

A "man dnf" will explain, somewhere in there.

'Course, I have no idea what else could happen, or not happen, if you exclude something like xorg.

I had kept using nVidia drivers only because it could silence a relatively lauder noise that occurred when I used nouveau. But I find this time, when I upgrade to F23, nouveau works perfectly fine and I will keep using it.

Any update on when nvidia will support Xorg 1.18, sort of the only thing holding me back for upgrading.

I'm in the same boat as the above users.

First of all, nouveau doesn't support my nvidia gtx 960 (NV126/GM206), their website talks about future support, but currently it can only run on software rendering.

I installed the binary nvidia via akmod-nvidia packages from rpmfusion, but the driver complained about my ABI version. I run with IgnoreABI which resulted in segmentation fault of the nvidia driver.

I guess we have to wait for new drivers by nvidia in the future before using F23. I'll keep my CentOS6 till that happens.

[zimon]

Or you can use F23 with current nvidia kernel, if you use use Xorg v. 1.17 instead of 1.18
In F23:

sudo dnf --releasever=22 downgrade xorg-x11-server-Xorg

[bosim]

Thanks for the status. I am happy Fedora 22 is supported yet another while, let us hope NVIDIA will provide drivers before end of life of Fedora 22. I also run on a unsupported nouveau chipset.

Nvidia typically wait for an official Xorg release before they update to any new ABI's in their driver releases.
