I updated/upgraded the kernel to from version 5.5.16-100.fc30.x86_64 to version 5.6.7.100.fc30.x86_64 and after restart en login my desktop is black and I can only see the mouse pointer, which I can still move.
From another similar discussion (upgrade of Fedora) I performed the command:
journalctl -b -1 -p4 --no-pager
Output:

I cannot make heads or tails from this output.
But if I restart with nomodeset in the boot menu the resolution is lower than normal (1600x1200).
Somehow the problem solved itself by rebooting again without nomodeset.
However, if I perform the same command
journalctl -b -1 -p4 --no-pager
I get a way longer output with some lines in red, which I have trouble reading it on a black background. An example of a line with red font: Glib-CRITICAL: g_child_watch_add_full: assertion 'pid > 0' failed
Should I do something?
EDIT: I should do something, but what?
After another reboot, and after login I got again a black desktop with only a mouse pointer visible.
And after another reboot, the program windows look they have a sepia filter over it.
If I open Terminal in Gnome Desktop it is complete black with only a blinking cursor. I can close Terminal with exit command. It works but is not readable.
