"Sorry, we only support 8 and 10-bit displays right now."

Today I updated Nvidia drivers to version 364.12 nad xflux stopped working, saying "Sorry, we only support 8 and 10-bit displays right now." I went through the release notes (http://www.nvidia.com/download/driverResults.aspx/100577/en-us) and found this:

Improved X colormap precision from 8 significant bits to 11 on GeForce GPUs. Quadro GPUs already used 11 bits of precision.

I guess that's the problem. Are there plans to fix this, or will I have to stay with old drivers to use xflux?

11! I guess we will have to patch that :)

@herf They turned it up to 11! I'll have to upgrade my drivers, that sounds cool! Nice precise colors!

Any ETA on that? :)

Any updates on 11-bit color support? My eyes are dying here on Arch since the last nvidia update.

Made an account just to agree with person above. I'm running arch and flux stopped worked with the same error as OP

Until f.lux updates with a fix, I've switched to redshift, more specifically the redshift-gtk-git PKGBUILD from the AUR, and I'd recommend it. In some ways it's even a bit better, for instance it changes based on time of day, so rather than a sudden change at sundown, your screen gradually shifts to red and back over several hours before sundown and after dawn. And the gui app actually works on my system, while fluxgui was a bit unstable.

Yeah, me too. My eyes are dying right now at 10pm. Just set up Fedora 24 with the new Nvidia driver and xflux gives me the same error. Can this please be fixed? Thank you.

I've been using redshift for now, it does the same thing as f.lux, but is a bit less user-friendly and a bit more customizable.

Quade321

Yeah, thanks for the tip. It's keeping my eyes from roasting, but I'd still like to have f.lux. Would be really nice if they had a Fedora repository too instead of just xflux and the Ubuntu repo with the whole GUI and everything.

@herf How's it looking? find the missing bit and patch it, yet ?

@herf Having the same problem here: just got a new laptop with a GeForce GTX 970M using the Nvidia driver and xflux won't work.

@f-lux-team Any progress on this? Thanks.

I could use a solution for this for Nvidia's proprietary 367.27 drivers. (Nvidia drivers and dependencies from SteamOS repos, rest of the system uses Debian 8 & BunsenLabs repos.)

I also registered just to say that we need this patched!

Sorry to bump an old thread but I had the same problem on my Antergos install and this I how I fixed it.

Disable lightdm and set gdm as the default DM

systemctl stop lightdm.service
systemctl disable lightdm

systemctl enable gdm
systemctl start gdm.service

Edit /etc/gdm/custom.conf to use Xorg instead of Wayland. Uncomment this line:

WaylandEnable=false

Start xflux
Profit, hopefully.

Note that this worked for me but is probably not the right solution and it might not necessarily work for you.

You said it. This won't work for most people. Are you downgrading your graphics driver with this fix, or is it just a Wayland related bug?

denniskig

The latter

@herf Hi herf,

did you have some time to patch this one after eight months? ;)

Would be awesome if you fix it and provide new binaries for us (Linux).

Our eyes are bleeding..

synthor

Btw. for me the workaround was to downgrade the Nvidia driver to 361.42.
