The reason this is a Fedora related issue is as follows:
By default, VirtualBoxes is blindingly white and refuses to respect dark mode settings. However, there normally is a way of overruling this using qt5ct: Giving VirtualBox a dark mode
However, there are two problems in Fedora when using Wayland (as far as I can tell anyways):
There is no ~/.profile file, only a ~/.config directory (and I’m not sure how I would change things in there to deliver the results I’m looking for in VirtualBox regarding dark mode)
Correct me if I am wrong, but qt5ct doesn’t seem to be compatible with Wayland more generally, but for security reasons I would strongly prefer to continue to use Wayland not Xorg.
What I find strange is I believe VirtualBox is a QT program, so I’m curious that if qt5ct isn’t compatible with my setup, then how is a QT program working on my machine in the first place? The fact it is working properly seems to indicate there must be a way of fixing the background in it and forcing it to be in dark mode as I’ve previously done on Ubuntu systems.
Thanks, I ended up creating that file and putting in the export statement. I also installed qt5ct and put in the requisite settings but it does not appear to have the same result as in Ubuntu (VirtualBox still has the same color scheme.)
I am also receiving some errors when trying to run qt5ct, there are here below:
I did some research regarding the second error and found a guide for Arch Linux saying to add “QT_QPA_PLATFORMTHEME=qt5ct” to the /etc/environment file: link
I’m not sure if this would work in Fedora and I’m wary of making changes like that to files without being 100% confident of the ramifications.
I’m guessing the fact that this isn’t in there could be causing the issue but I wasn’t able to find confirmation of this for a Fedora OS.
