Removal of the package 'sabily-gdm-themes' and rebooting had no effect on my situation.
Daniel, perhaps you have some insight into this. What information I've found in my internet search says that gdm/gdm3 defaults to Adwaita icon theme. I'm looked for "how to configure" type articles about gdm and none have been applicable or have had not effect. Do you know how to reconfigure gdm in Ubuntu 22.04? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1972080 Title: GNOME (non-Ubuntu) login screen mouse cursor is a semi-opaque white square (missing adwaita-icon-theme-full) Status in gdm3 package in Ubuntu: New Status in gnome-shell package in Ubuntu: New Bug description: Do not think this is hardware dependent, but I'm using an HPE MicroServer Gen10 Plus. I installed the server edition of 22.04. Post-Installation, I added some desktop environments. After logging in, these are working fine. However on the gdm login entry and password entry screens I had no mouse pointer icon. A semi-opaque white square tracked the mouse movements. My reading suggested that gdm defaults to using the cursor icon theme provided by the adwaita-icon-theme package. I discovered this theme comes in two sizes, a basic, smaller package installed automatically and a larger "full" package. $ apt list 'adwaita-icon-theme*' Listing... Done adwaita-icon-theme/jammy,now 41.0-1ubuntu1 all [installed,automatic] adwaita-icon-theme-full/jammy,now 41.0-1ubuntu1 all [installed] $ The gdm mouse pointer appears and disappears with installation and removal of the package "adwaita-icon-theme-full". Either gdm's dependencies should include the "full" package OR the appropriate mouse pointer icons should be moved from the full to the basic "adwaita-icon-theme" package.
