From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

QT Theme management in Sway (mander.xyz)

I use VLC,Keepass,Kdenlive and few other QT Apps on my sway setup. So, wanted to configure their themes from Sway. I installed qt5ct and qt6ct and did export QT_QPA_PLATFORMTHEME=qt5ct in bashrc and .profile. While runnin echo $QT_QPA_PLATFORMTHEME it is showing qt5ct but it is not working showing that error message that QT_QPA_PLATFORMTHEME need to be set as qt5ct or qt6ct when launching from .desktop But when launching from terminal they start and function properly but do not change any theming.

A really common issue with sway is that it doesn't run as a login shell, so none of your .profile or other environment settings get sourced when you login. I think that might be the problem here.

Try closing your sway session, then login to a tty and run sway. If the qt themes work properly then it's definitely an environment issue.
