Try restarting the system. Upgrading some packages will cause great interference to the system. In most of my recent updates, gnome often has this problem. I tried to create a new user to start a gnome desktop without any settings, but it still failed (Translator's note: or delete all the gnome Desktop configuration files under this user ). However, restarting the system can completely solve this problem. Translation: foreigners have done this silly thing.

There is a black X in the center out of the chart with the mouse over my screen. This problem is caused by hardware acceleration of the cursor. This problem can be solved by modifying the/etc/X11/XF86Config-4 file and adding the following Configuration:
Option "HWCursor" "false"
Or:

Option "SWCursor" "true"
In the Device section. Note that this option is different for different video cards. To confirm that the information you entered is correct, see the man explanation of the video card. Column: ATI card: man radeon Nvidia card: man nv the result should be similar:
Section "Device"
Identifier "nVidia Corporation NV25 [Geforce4 Ti 4600] 0"

BusID "PCI: 1: 0: 0"
Option "HWCursor" "false"
EndSection
