XFCE4 installation from MXPI Popular Apps fails [Solved]

I don't know what that theme is supposed to look like, but I think that Xfce Appearance will not change that file, so unlikely the gtk2 theme actually changes when you change it with Xfce Appearance.

Ok, but in the screenshots Thunar is reflecting what I've selected and it changes back and forth from MX Comfort to (my) default theme. Also I know this theme works in XFCE4 because it was also used in AVL 21 which was still purely XFCE4 (4.18) and the MX Tools matched up with it fine.

I don't know what's amiss but I don't think it's the theme itself or the theme chooser.. I can't imagine where that color palette is coming from, there are 2 MX Comfort themes and 3 AVL themes and none of them have brown in them..

thunar isn't gtk2.

so the .gtk2rc file changes when you change theme? because I don't even have that file. but whatever is in that file will supersede what thunar sets, at least for gtk2 applications, which is what Qt theme follows.

Ok, but the same gtkrc file is present in both installed DE's and Enlightenment is just using a hardwired QPA Platformtheme environment variable, but let me try deleting the gtkrc file and see what happens..

*ADDED

Meh, deleted gtkrc file completely logged out and same result, weird background color still there. Good to note it doesn't really need to be there, it's was leftover from desperation trying to make SVG Icons work which was another problem...

Anyway enough of your time wasted, it's nothing obviously related to how MXPI installs XFCE4 so it's some other unknown quirk apparently whether because there is already another DE on the system who knows..? XFCE4 and KDE don't play nice theme wise either..

FWIW,

I'm encountering even worse QT palette problems in testing LXQT, something is very weird here, need to move testing to bare metal I think..

yes kde colors can mess with things too, although usually on the gtk3 side of things. they uses css overrides to make colors match.

one other thing. the colors in the gtk2 definition for a theme don't have to match the gtk3 ones. there is at least one theme out there where they are very different, and its confusing too.

As you can see the QT colors are brown and orange with no correlation to the dark and blue GTK theme:

If you look at the icons in the tweak window it seems to me as if all colors are being inverted/altered.
Maybe it's nothing to do with the theme and something with how qt/gtk2 windows are being rendered?

idesk had a perhaps similar problem with svg icons in mxfb and always inverted the colors.

That actually makes a lot more sense since those colors are not in any installed theme, the inverted theory seems quite plausible, of course 'why' is the big question. I can't fathom why they're not inverted in Enlightenment but seem so in both XFCE4 and LXQT..

*EDIT

I just did some work in GIMP for the first time since installing this ##$$**& nVidia 4080 Video Card and now I'm getting very odd and unexpected colors when using 'Colorize' I think maybe the root of this issue is the damned Video card...!?

[Melber]

maybe you installed the video card upside down?

Good one! I LOL'd for real!
