I installed the Fedora 40 LXQt spin, and have upgraded to 41. I use Openbox by itself, and am trying to migrate to Wayland and Labwc. I use some Qt apps, and theming them in Fedora has not worked as it has in other distros over the last 2 years. I need a dark theme as bright themes hurt my eyes. Any help or pointers to info would be appreciated.
Since LXQt is a Qt based spin, there should perhaps be tools preinstalled / available on your system to achieve a dark look. There is this page below about theming options for LXQt, have you seen that already?
I start with LXQt, and run Openbox by itself, but theming is still hit and miss, even in LXQt, and it’s worse in Openbox alone or Labwc. I suspect there might be some applications that aren’t built on the same frameworks version, and there will be further challenges adjusting the Wayland ways of doing things.
