For some reason Blender is not responding properly to the default key commands used in conjunction with the mouse for directing modeling operation commands, everything is running incorrectly including missing sections of the gui interface window where the x for closing the program and – for closing the window of the program to the task bar instead of shutting down completely have disappeared.
I have several different desktop environments installed within the Fedora Design Suite 43 operating system; Cinnamon, the default Gnome, and Plasma. The above mentioned problem does not occur when I use the Gnome or Plasma desktop. As an attempt to isolate the problem further I created on the same hard drive another separate partition and installed the Fedora Cinnamon Spin for 43. With that operating system Blender also works fine using the default Cinnamon desktop for that Spin of the operating system. For some reason within the Fedora Design Suite operating system the Cinnamon desktop which installed reading within the drop down menu of the display manager where you choose which desktop you want to run the Cinnamon option reads “Experimental”, whereas the Spin operating system for Cinnamon does not read that way. Actually had additional problems within the Design Suite 43 Cinnamon desktop when first installed, all the keys where not creating the proper characters within Libre Office Writer or Abiword when pressing the keyboard. After a couple of weeks after an update the problem with these programs disappeared yet the different problem is lingering within Blender using Cinnamon within the Fedora Design Suite 43 operating system.
Anyone have any idea what might be causing this problem, I have spent a lot of time trying to find a way to fix this problem or at least identify where the root cause of this might be yet have run out of ideas for things to try. I have ruled out a problem with the Blender program since I have at least five different versions of the program installed, one through the repository and the others as standalone files isolated within their different directories. They all have the same results within Cinnamon, if I had a corrupted version of Blender the problem would only occur within the corrupted version instead of all. I keep package files available in separate partitions and hard drives of Blender and use them over again after a fresh install of an operating system, these package files have run fine on Fedora Workstation 42 and earlier versions of the Design Suite, problem started with version 43.
If this may be of any help, when I open Blender through a terminal in the problematic Cinnamon desktop I get this output:
libEGL warning: failed to get driver name for fd -1
libEGL warning: MESA-LOADER: failed to retrieve device information

If I use a terminal to open Blender within the Design Suite 43 operating system using Gnome or Plasma the above readout does not occur in the terminal and the Blender program opens normally and runs properly.
