Okay, this worked for me, too. But that is only gdm, right? Strange. It still must have been broken by the recent driver update. And no, I didn't know that Wayland isn't supposed to work. I was pretty sure that I've been using this set-up unchanged since switching to gnome-shell about a year ago.

Can you try looking at the output of iotop? It might give us a hint which process is doing a lot of I/O.

Does the system behave the same way when you boot it without a graphical user interface?

Fixed slowness by removing the 390.25 akmod:

sudo dnf remove akmod-nvidia xorg-x11-drv-nvidia*

Manually installed version 384.111. Everything works fine for now. Will check manual installation of 390.25 as well and raise the issue with nVidia (if that is even possible).

Thanks, good hints all around. For now I've only manually installed the previous driver version (384.111), and it works fine, but I'm sure I'll get tired of the manual process after the next few kernel updates. I have only looked into dkms superficially so far, but if it works as you describe I might just switch over.

Agreed, nVidia doesn't have a good track record with Linux. Akmod kept it off my back for about a year, and now this. Nouveau doesn't work too well with my laptop, and the nVidia drivers still offer some functionality that I'd like to continue using.

Thanks! Unfortunately there is no NVIDIA-Linux-....run package anywhere on my system, except a very old one that I've downloaded a long time ago. Any other hints in that direction?

Meanwhile I've tried a complete de-installation and re-installation of the akmod and all nvidia libs via dnf. Didn't help one bit.

I also found out that the slowdown comes from the process gnome-shell burning my CPU, all 16 cores of it. Could be any number of things I guess.

Next I'll try a manual installation of the driver, removing the akmod. Gaaah, that's what I really want to avoid.

Hi! The offline update just installed the latest NVidia driver, 390.25. The system is otherwise a fully up-to-date F27, using the Gnome 3 desktop environment.

Since the update, the graphical system is so slow as to be barely usable, starting from the login screen. The mouse pointer barely moves, keystrokes are registered but with delays of one to two seconds, and generally everything is slow like this, including desktop animations etc. It almost seems like it is a general slowdown that keeps the system busy for one or two seconds, then processes inputs for a few millisecs, then is busy again. Logging in takes one to two minutes, launching applications similarly. Booting the multiuser target works, the system operates at normal speed then.

Also my screen configuration does not work. I'm using a laptop but usually have the internal screen off, only using an external one that's connected via HDMI. This seems to indicate that something with the driver or something in the X system does not work as intended.

I've spent an hour poking around but can't find the cause: journalctl, dmesg, xorg log -- nothing shows anything interesting.

I've had a lot of problems with the nvidia drivers in the past, but they could typically be resolved by booting the multiuser target, then forcing akmod to reinstall. Not now though, it keeps being slow.

Any hints about what I could try next? I'm fairly certain it is the driver, but it may be something else also, so how do I find out? I'd be fine with downgrading the driver for now, but to be honest I don't know how to that, and the dnf history doesn't seem to show the offline installation (last entry is from a manual update a few days ago).
