Update fluxapp.py - Githubissues

linuxazo commented 2 years ago

Making fluxgui up-to-date with current development version of Debian. AyatanaAppindicator packages are are straighforward replacement in Debian for unmaintaind Appindicator packages. Other than this, fluxgui needs no redshit, since redshift also does not work under wayland. Fluxgui/xflux works perfectly under X11. Those errors are from trying to run fluxgui under wayland, which requires compositor level implementation of color temperature changing. Fluxgui/xflux are awesome.

This and PR #151 have been combined into cb4b596, thanks for the PRs (but better to just make a single PR for related changes like this). I read that Ayatana appindicator is not supported in Fedora, so I added logic in ec72bcf to fallback to plain appindicator if the Ayatana version is unavailable.

I think you're wrong that xflux always works on X11, and that Wayland is the only cause of Issue #27. For example, I'm using X11, not Wayland, and xflux fails for me in exactly the way described in #27. On the other hand, Redshift does work for me, and is what I actually use. Take a look at #27 for more context.

Dear Nathan, Fist of all, thank You so much for Your kind response. Thank You for the suggestions with regards to the PRs. I will do my best to follow them. I used flux on/off for years on both Windows and Linux. Lots of respect from my side you've earned for keeping touch. Looking into this situation deeper, my conclusions so far are: xflux/fluxgui seem to work flawlessly on open source x11 drivers (amdgpu tested 100% working). I will test on intel graphics laptop as well. The error #27 I get as well if I am using closed source nvidia driver, which is, believe me, not the only discepancy when using nvidia driver in discrete mode (so I opt to use prime offloading in my amd/nvidia optimus laptop setup). For example xrandr in nvidia discrete mode has only native resolution, the x11 protocols do not work as expected (scaling/multidpi/multidisplays, etc...) I could even test further with nouveau driver on my other machine and could be able to confirm that all amdgpu, nouveau and intel drivers work 100% with xflux/fluxgui. I am using Debian Sid (Developer version with the latest libraries and software) and xflux/fluxgui works no problem (using as an applet in KDE Plasma). Please share your experiences on this if you don't mind and let's stay in touch.

First, let me clarify that I don't know anything about X servers or how xflux works! Note that xflux is a closed source program and that fluxgui was created independently of xflux. Also, I'm not the original creator of fluxgui, just the current maintainer, and have no relationship to the xflux project.

I'm using Redshift (which you say doesn't work on Wayland) and xmonad (which definitely doesn't work on Wayland), which makes me think I'm "using X11" as I claimed. However, looking into this more, I have both Xwayland and Xorg processes running on my machine, so I might be using X11 via Xwayland, I'm not sure. Would that count as "using Wayland" in the way you're concerned about? I must admit that I didn't even know that Xwayland was thing: I thought a person either used Wayland or Xorg.

In any case though, lots of people have problems with xflux, xflux is unmaintained (the issue #27 has been reported upstream long ago), and xflux is closed source, whereas Redshift works well, Redshift is maintained, and Redshift is open source. So I maintain that Redshift seems to be the way forward.

In case it helps, here are the graphics related processes I can find in the output of ps -feH:

Dear Nathan, I am aware of your status and the situation regarding xfluxgui. Also, I am not a programmer by profession, just a person who has used Linux for over two decades.

Since, I see you have an Intel graphics card. I think gdm is the source of your problems. GDM (GNOME Display Manager) by default uses Wayland and starts a Wayland session, which in turn, even though you're using intel open source graphics driver, impairs the use of xflux/fluxgui.

I supposed your using Fedora, and according to: https://docs.fedoraproject.org/en-US/quick-docs/configuring-xorg-as-default-gnome-session/

You could try and make GDM use X11 by default: Edit

/etc/gdm/custom.conf and uncomment the line:

WaylandEnable=false

Furthermore, in the same file,

Add the following line to the [daemon] section:

DefaultSession=gnome-xorg.desktop

And try and reboot your computer. See if xflux/fluxgui works then.

Addendum: You xmonad window manager is working under XWayland (X11 compatibility layers for X11 apps under Wayland session). thus making redshift work under XWayland as well.

Under pure Wayland session (GNOME/KDE/Sway) redshift will NOT work. There are other projects or implementations for Wayland (again nVidia does not implement color temps chaning under wayland at all, yet...).

Let me know if it works. Kind regards, Safir

Dear Nathan, I followed through the whole discussion on: https://forum.justgetflux.com/topic/2373/sorry-we-only-support-8-and-10-bit-displays-right-now/62 And my point still stands. Those issues arise from trying to use xflux under Wayland session. And it is not like xflux has not been maintained, it is just that people failed to pinpoint GDM and Wayland introduction (Wayland being default window system from Fedora 25) and others mainly using Ubuntu (again GDM defaulting to Wayland from the time of those bugreports).

For confirmation that redshift does not support Wayland, there are many references. For example, this Arch Linux wiki article (right at the beginning): https://wiki.archlinux.org/title/redshift

Also, if you don't care about using gnome, you could try using another non-Wayland display manager or no display manager at all, and that way, you would be running under X11 for sure. LightDM comes to mind as an X11 display manager (there are many others).

Dear Nathan, I am aware of your status and the situation regarding xfluxgui. Also, I am not a programmer by profession, just a person who has used Linux for over two decades.

Since, I see you have an Intel graphics card. I think gdm is the source of your problems. GDM (GNOME Display Manager) by default uses Wayland and starts a Wayland session, which in turn, even though you're using intel open source graphics driver, impairs the use of xflux/fluxgui.

I supposed your using Fedora, and according to: https://docs.fedoraproject.org/en-US/quick-docs/configuring-xorg-as-default-gnome-session/

You could try and make GDM use X11 by default: Edit

/etc/gdm/custom.conf and uncomment the line:

WaylandEnable=false

Furthermore, in the same file,

-

Add the following line to the [daemon] section:

DefaultSession=gnome-xorg.desktop

And try and reboot your computer. See if xflux/fluxgui works then.

Addendum: You xmonad window manager is working under XWayland (X11 compatibility layers for X11 apps under Wayland session). thus making redshift work under XWayland as well.

Under pure Wayland session (GNOME/KDE/Sway) redshift will NOT work. There are other projects or implementations for Wayland (again nVidia does not implement color temps chaning under wayland at all, yet...).

Let me know if it works. Kind regards, Safir

First, let me clarify that I don't know anything about X servers or how xflux works! Note that xflux is a closed source program and that fluxgui was created independently of xflux. Also, I'm not the original creator of fluxgui, just the current maintainer, and have no relationship to the xflux project.

I'm using Redshift (which you say doesn't work on Wayland) and xmonad (which definitely doesn't work on Wayland), which makes me think I'm "using X11" as I claimed. However, looking into this more, I have both Xwayland and Xorg processes running on my machine, so I might be using X11 via Xwayland, I'm not sure. Would that count as "using Wayland" in the way you're concerned about? I must admit that I didn't even know that Xwayland was thing: I thought a person either used Wayland or Xorg.

In any case though, lots of people have problems with xflux, xflux is unmaintained (the issue #27 https://github.com/xflux-gui/fluxgui/issues/27 has been reported upstream long ago), and xflux is closed source, whereas Redshift works well, Redshift is maintained, and Redshift is open source. So I maintain that Redshift seems to be the way forward.

In case it helps, here are the graphics related processes I can find in the output of ps -feH:

I switched GDM to use Xorg using the WaylandEnable=False you suggested, and also tried using LightDM with the i3 window manager to avoid Gnome. In both cases xflux fails in the usual way, as described in #27 (e.g. xflux12 prints the "Sorry, we only support 8, 10, 11, and 12-bit displays right now" error message and similar for the previous version of xflux). Below I've attached the complete output of ps -feH from before and after logging into to a WM, for both GDM with xmonad+Gnome, and LightDM + i3, in case you want to convince yourself that there's no more Wayland involved.

So, I think we're back where we started: xflux doesn't work and redshift does, so I will continue to suggest that people having the #27 issue try redshift.

Also, I don't understand your argument that Flux for Linux is still maintained. The last release on the Linux flux page is from 2013 (https://justgetflux.com/linux.html), and the xflux12 binary in the forum thread about the problem we're debugging right now is from ~2015. Compare this with the Windows version of flux, which was last released in 2021 (https://justgetflux.com/linux.html). I think your idea is that the problem is due to Wayland, but the evidence in my case shows that it xflux is also broken on my Xorg. And, if it turns out that I'm actually using Xwayland (even though I don't have any Xwayland processes on my machine anymore), then if "xflux is maintained", I think the maintainers should update it to work on Xwayland, since redshift works there.

Finally, a hypothetical: what if switching my GDM3 from Xwayland to Xorg had solved the problem. Should we conclude that fluxgui doesn't need redshift support? I think the answer is "no", since many people would prefer to have something that "just works", and it seems that something is redshift.

Here is my ps -feH output:

For confirmation that redshift does not support Wayland, there are many references. For example, this Arch Linux wiki article (right at the beginning): https://wiki.archlinux.org/title/redshift

Since, I see you have an Intel graphics card. I think gdm is the source of your problems. GDM (GNOME Display Manager) by default uses Wayland and starts a Wayland session, which in turn, even though you're using intel open source graphics driver, impairs the use of xflux/fluxgui.

I supposed your using Fedora, and according to: https://docs.fedoraproject.org/en-US/quick-docs/configuring-xorg-as-default-gnome-session/

You could try and make GDM use X11 by default: Edit

/etc/gdm/custom.conf and uncomment the line:

WaylandEnable=false

Furthermore, in the same file,

Add the following line to the [daemon] section:

DefaultSession=gnome-xorg.desktop

And try and reboot your computer. See if xflux/fluxgui works then.

Addendum: You xmonad window manager is working under XWayland (X11 compatibility layers for X11 apps under Wayland session). thus making redshift work under XWayland as well.

Under pure Wayland session (GNOME/KDE/Sway) redshift will NOT work. There are other projects or implementations for Wayland (again nVidia does not implement color temps chaning under wayland at all, yet...).

Let me know if it works. Kind regards, Safir

I'm using Redshift (which you say doesn't work on Wayland) and xmonad (which definitely doesn't work on Wayland), which makes me think I'm "using X11" as I claimed. However, looking into this more, I have both Xwayland and Xorg processes running on my machine, so I might be using X11 via Xwayland, I'm not sure. Would that count as "using Wayland" in the way you're concerned about? I must admit that I didn't even know that Xwayland was thing: I thought a person either used Wayland or Xorg.

In any case though, lots of people have problems with xflux, xflux is unmaintained (the issue #27 https://github.com/xflux-gui/fluxgui/issues/27 has been reported upstream long ago), and xflux is closed source, whereas Redshift works well, Redshift is maintained, and Redshift is open source.

Also, if you don't care about using gnome, you could try using another non-Wayland display manager or no display manager at all, and that way, you would be running under X11 for sure. LightDM comes to mind as an X11 display manager (there are many others).
