On my screen there is a black X in the center in addition to the mouse chart. This problem is caused by the hardware acceleration of the cursor. This problem can be resolved 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 have entered is correct, please refer to the man explanation for the video card. Columns: ATI card: Man Radeon Nvidia card: Man NV So the result should look like this:

section "Device"
Identifier "NVidia Corporation NV25 [Geforce4 Ti 4600] 0"
Driver "nvidia"
Busid "pci:1:0:0"
Option "Hwcursor" "false"
Endsection
