Weird difference in KDE Connect SMS UI between two systems

Help
1

I have a desktop (brawn) and a laptop (deft) both running Linux Mint 22.2 Cinnamon. I have built both of these systems with the same settings and such; i.e., I do the base config using a script.

I am running the KDE Connect app on both and it functions fine on both systems. However, on brawn, I can see icons in the toolbars and on deft, it is not showing any icons. I’ve searched and found an article in the Linux Mint forum which lists several likely fixes (see the apt list at bottom) – and one of which says it fixed it. But in my case, brawn doesn’t have any of these fixes but looks fine and deft also does not have any of the listed fixes but does not show icons. I’ve looked around in ~/.config/kdeconnect but have not seen anything pertinent or which seems to be noticeably different between the two apps.

I found the issue: It appears that, when using the Simplified themes under Cinnamon (default desktop on Linux Mint), that qt5ct can’t pick-up the icon them by default. Comparing the qt5ct.conf file between the two systems, I noted this line:

icon_theme=Mint-Y-Sand

Which, apparently, was picked up during a time when I was trying different themes on brawn (though I have since gone back to Simplified themes). Running qt5ct on deft and explicitly selecting on the “Icon Theme” tab, the appropriate “Mint-Y-Purple” (to match my current desktop theme), I now see the icons appearing on deft as well.

Yeah, probably seems obvious to those more familiar with Qt-based apps. And I should have caught this earlier but – well, I didn’t. :smirking_face:
