• Qt5ct issues


    So, there was an update recently to qt5 stuff and now I can’t make nheko (matrix client) work. Here is its output:

    Any idea what could be happening? I am using i3wm.

  • qt5ct is basicly to match your gtk to qt5 .

    add QT_QPA_PLATFORMTHEME=“qt5ct” to your /etc/environment , you also probably got some qt5 settings of qt5ct to choose theme to use.

    dont know what kinda program it is? looks as other issue?

  • @ringo32 I am sorry, but I don’t know what you mean by your post. adding that environmental variable does not help the issue.

    This is the program: https://github.com/Nheko-Reborn/nheko/

  • for qt5ct there is normally qt5ct oin menu , is just to select qt theme to use for that qt theme. does not use gtk theme QT_QPA_PLATFORMTHEME=“qt5ct” need to be set to use qt5ct as configurator

    i gues somewhere in xsession can but i do perosnally in /etc/enviroment , then reboot

    you have to launch qt5-settings and select theme if that does not start te program then some rule set is wrong i gues?

  • I do have a theme selected in qt5 settings. The issue arised with the newest updates from antergos.

  • @markoff Is it possible to downgrade those updates? Did you view history in the update manager and try to figure out which updates messed it up?

  • Sadly, I already tried to downgrade a few things but couldn’t make it work. I think it broke in this update:

  • @markoff Sorry to hear that. When i break something and it’s usually my fault because i can’t leave well enough alone i end up reinstalling. But, i always learn something in the process! ☺

  • @ringo32 said in Qt5ct issues:


    oh yeah i forgoth, if you build stuf from AUR, and in a update that package is broken, did you rebuild the package at current? downgrading stuf dont work… rebuilding in some cases Yes. …

    did you rebuild the package since also relies on cmake etc… ?

  • @ricklinux But in this case it is not my fault. It has to do with Antergos. Antergos users are having this issue, Arch users are not. One idea is to remove antergos and just go with pure Arch.

    Here is one issue regarding this: https://github.com/Antergos/antergos-packages/issues/455

    The solution there doesn’t fix it for me though, possible because I am using i3?

  • I should try to rebuild that package since its from Aur. Thats also a basic aur rule, even you use pure arch. but every update it can be back. if you not rebuild package you dont know, sometimes a package need a rebuild if something is changed. thats currently i set my cent on if on other packages qt5 works on theming. rebuild can fix some stuf.

  • basicly that config is set in Xsession of lightdm, if you not use lightdm, those configuration does not configured in the system, so adding in /etc/environment works always

  • I already rebuilt the package and it didn’t help.

    may AUR PKGBUILD needs to be updated by the providing user…

    reminder: AUR builds are not official packages, this are buildinstructions provided by users.

  • @markoff Sometimes when it’s already broken the fix isn’t going to fix it. Been there done that!

  • @markoff https://wiki.gnome.org/Apps/Fractal
    if you are under i3 i would take this:
    sudo pacman -S fractal

  • @joekamprad, fractal doesn’t support E2EE while nheko does.

    Also, I think it’s important to note that it was an update that broke nheko and only antergos users are experiencing difficulties. So it’s not nheko’s fault, because if it was arch users would also experience it.

  • @markoff said in Qt5ct issues:

    only antergos users are experiencing difficulties…

    the problem at Antergos with qt5ct was that it was used under KDE/plasma, where it should not be used.
    Under i3-wm it is recommended to be used to configure Qt-style.
    You can easily remove Antergos pre-configs for qt5ct by moving them out of the way for the current user:
    mv ~/.config/qt5ct ~/.config/old-qt5ct
    original Antergos configs for newly created users: /etc/skel/.config/qt5ct
    As packages updated are from Archlinux repositories…

    Antergos have this ones only:

  • flatpak may work for you:

    sudo pacman -S flatpak
    flatpak install flathub io.github.mujx.Nheko
