How to fix mouse cursor flickering or disappearing?
We may encounter mouse flickering or disappearing issue, here are the possible causes and solutions:
Possible cause 1:
Screen settings: resolution and refresh rate.
Can be checked (On KDE) under systemsettings5 then display and monitor
Possible cause 2:
Screen compositor: it could be caused by the sale-method/rendering-backend/tearing-prevention those settings can be changed (On KDE) under systemsettings5, display and monitor then compositor… apply new settings and compare
Possible cause 3:
Display server mis-configuration: you can regenerate the display server config file with X -configure or similar but first make a copy of /etc/X11
Possible cause 4:
System failure, crash, reboot: on system failure especially for systems equipped with SSD you may loose important files; Files under directories like /home/user/, /etc/ or /usr/ can cause serious damages, as these directories contain important settings/packages files for different aspect of the desktop. usually when a file is lost after a crash, the file may be completely deleted or zeroed, you can then search for file with zero size and check out if important file are corrupted with the command find /etc -size 0 -print (this is for /etc) you can also check packages integrity for missing/modified file, on rpm based system it’s done with the command rpm -Va you would then reinstall the broken package.
A common situation in this case is loosing the file /etc/X11/xorg.conf or one of the config file under /etc/X11/ responsible for the display server; If recovering the file is not possible the config can be regenerated with X -configure or similar command
Possible cause 5:
Mis-configuration of user files under /home/user… you can verify this by login with an other user… to fix it eventually delete and recreate the user (after backup)
Possible cause 7:
Graphic drivers, you need to check if you are using the proper graphic driver and or try a different version of the used driver, usually this often happen with nvidia graphical cards.
Other…
The listed situations are not the only possibilities of failure.
