Public bug reported: From https://askubuntu.com/q/1411558:
"Just installed Ubuntu server 22.04 and as I needed a DE, followed some tutorials where most of them suggested that I can install gnome (or ubuntu-desktop) using the tasksel command. After doing so I encountered two problems: the mouse pointer on desktop is showing as a solid gray square ⬛ and the hotspot is at upper left corner. However when I run any gui app the pointer is drawn perfectly fine. How can I fix this issues?" And the top answer, indicating it's happening more for 24.04: " I faced the same problem on Ubuntu 24.04 beta, on GNOME / Ubuntu desktops, using my preferred cursor theme DMZ-White. When the mouse is over the top bar or the dock/launcher (whatever it's called), the mouse pointer is a light gray (almost white) square. It seems to me that the icon theme is missing the default file. For me this solution worked: Check which cursor theme you're using. Start gnome-tweaks and go to Appearance -> Styles -> Cursor. In a terminal, navigate to its directory under /usr/share/icons and then the cursors subdirectory underneath, e.g. cd /usr/share/icons/DMZ-White/cursors/ (The cursor theme's name may not directly map to the filesystem directory name, use common sense to find it.) Then create the missing symbolic link (or copy the file): sudo ln -s left_ptr default Then switch to a different cursor theme in gnome-tweaks and back to this one, for the change to take effect. Or log out and log back in." I can confirm that I am also affected by this bug, and the suggested workaround appears to fix the issue. ** Affects: dmz-cursor-theme (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065947 Title: DMZ-White theme shows gray square in place of curson on Ubuntu 24.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dmz-cursor-theme/+bug/2065947/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
