I recently performed a clean install of Xubuntu 18.10, and I'm experiencing this more recently. Also, it appears I'm already using lightdm-gtk-greeter and do not have unity-greeter installed.
I'm glad you identified the issue you have with unity-greeter. I think there might be multiple issues with multiple greeters here. I tried checking to see what was in my lightdm.conf to find it does not exist with the default install on my system. $ less /etc/lightdm/lightdm.conf /etc/lightdm/lightdm.conf: No such file or directory What I do have: $ ls -al /etc/lightdm/ total 28 drwxr-xr-x 3 root root 4096 Oct 17 17:38 . drwxr-xr-x 139 root root 12288 Mar 16 15:19 .. drwxr-xr-x 2 root root 4096 Aug 29 2018 lightdm.conf.d -rw-r--r-- 1 root root 2970 Sep 17 20:17 lightdm-gtk-greeter.conf -rw-r--r-- 1 root root 452 Aug 29 2018 users.conf $ ls -al /etc/lightdm/lightdm.conf.d total 8 drwxr-xr-x 2 root root 4096 Aug 29 2018 . drwxr-xr-x 3 root root 4096 Oct 17 17:38 .. $ less lightdm-gtk-greeter.conf [greeter] #background= #user-background= #theme-name= #icon-theme-name= #font-name= #xft-antialias= #xft-dpi= #xft-hintstyle= #xft-rgba= #indicators= #clock-format= #keyboard= #reader= #position= #screensaver-timeout= $ less users.conf [UserList] minimum-uid=500 hidden-users=nobody nobody4 noaccess hidden-shells=/bin/false /usr/sbin/nologin Should the default Xubuntu/Ubuntu lightdm-gtk-greeter install be creating and populating /etc/lightdm/lightdm.conf by default? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770948 Title: Mouse cursor size is large and inconsistent on 4K displays in XFCE To manage notifications about this bug go to: https://bugs.launchpad.net/xfce4-settings/+bug/1770948/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
