Core Control by Dead Mozey project

Hi everyone!

I would like to point an issue occurred with this useful application for AMD systems (CPU and GPU) in the last week, after I’ve installed the latest Tumbleweed updates. Well, it seems that the GUI but the program itself won’t load anymore, not even through the autostart session of my XFCE desktop.

I have no idea why, waiting for suggestions. Thank you and sorry if I’ve stumbled here all of a sudden.


Sorry, I forgot to add the corectrl link - Install package home:Dead_Mozay / corectrl

Not a piece of software I’m familiar with and I don’t use XFCE.

The first place to start would be with the journal to see if any relevant errors are logged.

Switch to a virtual terminal “ctrl-alt-F2” login as your normal user and execute “sudo journalctl -f” to initiate journal ‘following’, switch back to your normal graphics session “ctrl-alt-F7” and launch Core Control, wait a few seconds then switch back to VT2 “ctrl-alt-F2” to see any journal entries. (Terminate journal ‘following’ with “ctrl-C”)

As you did not tell which version of corectrl you are using…one can only guess. But on github are some problems reported that corectrl 1.3 crashes on start.

This problems shouldn’t show in journal but if you start it from commandline you should get some usefull crash informations…

Ok, it’s 1.3, if I run corectrl from terminal it says: corectrl
qt.qpa.plugin: Could not load the Qt platform plugin “xcb” in “” even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.


and rerun the application, there may be more detailed error information.
