Hello SuSE universe - I am running OpenSuSE 15.4 x64 with the KDE/Plasma desktop - Operating System: openSUSE Leap 15.4 KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 Kernel Version: 5.14.21-150400.24.88-default (64-bit) Graphics Platform: X11 Processors: 8 ×? Intel®? Core?? i7-6820HK CPU @ 2.70GHz Memory: 31.3 GiB of RAM Graphics Processor: llvmpipe The font size of the Emacs menus is way to small for this old man to read, so I thought to try and figure out how to increase it. Internet searching led me to believe that the font size for the Emacs editor is controlled by QT. When I attempt to launch the Qt5 configuration tool, I get the following error message - "The QT_QPA_PLATFORMTHEME environment variable is not set (required value: qt5ct)." Digging further into the realms of the internet, most suggestions I found, on how to solve this problem, was to edit the environment file /etc/environment and set the following - QT_QPA_PLATFORMTHEME=qt5ct However, doing so leads to yet another problem, upon rebooting my laptop, somewhere in the process of setting up the KDE/Plasma desktop the system hangs and becomes completely unresponsive. I have to then reboot to init 3, and edit out this environment variable setting, and reboot again to init 5 to get my desktop back and working again. So, my question dear SuSEites, what do I do now to get the Qt5 configuration tool to work, or more importantly how to I increase the size of the menu fonts in Emacs? SuSE must have it's own way to set up the Qt5 tool and/or set the size of the Emacs toolbar/menu fonts. Can some kind guru shed so light on this dark hole? Thanks as always, in advance... Marc --
