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

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.

montyboy

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

ntc2ntc2

@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.

fade2black244

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

Makitk

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.)

tlind

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.

AlexV

May be I repeat, try to use redshift. It analog xflux.

This is not helpful at all.

samkostka

Is there an ETA on the fix? I've been using redshift for the time being but a recent-ish update made it just not work at all anymore, and I'd really love to not be blinded by my PC late at night.

@samkostka

I actually think there won't be any patch for this.

I have no NVIDIA+Linux machines to test on, but I posted a possible fix here:

@Makitk

Can you get a stack?

gdb -ex run --args ./xflux11 -z 90210

Then when it crashes:

@herf , I tried single stepping with backtrace after each step (by getting close to the crash and then defining a function that does step; bt as described here: http://stackoverflow.com/questions/1262639/multiple-commands-in-gdb-separated-by-some-sort-of-delimiter).

Here's the output at the crash (the first stack trace is before the crash; scroll to the end for the similar stack trace at the crash, i.e. at fork.c:152):

$ gdb --args ./xflux11 -z 97232
