Meanwhile I am running Xubuntu 18.04 (and testet also 20.04), but the
problem is still there:
Tasks: 287 total, 2 running, 186 sleeping, 0 stopped, 1 zombie

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

Also all xfce hot keys like Ctrl-F2 Alt-F4 Alt-F6 ... do not work.
But some time (1..3 minutes) after login everything seems ok!
The Xorg process is idle and all xfce hot keys work as expected.
But when I change the console with Ctrl-Alt-F1 and back with Ctrl-Alt-F7
the problems described above are back ... and do not vanish, until I
terminate the X-server and re-login.
I have a second (test-) user named "tux" who has no problems at all!
So, it MUST be an configuration error with my main user "framstag".
I have tested:
mv ~/.config/xfce4 ~/.config/xfce4_saved
[logout]
[login]
But the problem is still there :-(
I have thousends of config files in my $HOME and I do not want to remove
$HOME/.??*
Any suggesstions how I can debug this problem?
