I think the reason that lightdm-webkit-greeter is not affected is that it links against GTK2, not GTK3. Both GTK2 and GTK3 define a gdk_window_set_cursor() function: the GTK3 version uses XInput's problematic XIDefineCursor function, while the GTK2 version does not. As for the patch to lightdm-gtk-greeter: I think that works because with the patch, gdk_window_set_cursor() is no longer called on the root window, it's only called on windows created by the greeter itself. These windows disappear once the greeter exits, so any device cursor definitions would disappear with them. It's not a problem when a program sets device cursors on it's own windows: that only affects those windows and the program (presumably) knows how to deal with them. It's when something sets a device cursor on the *root* window that we have problems, because lots of programs need to work with the root window and many of them don't use XInput2. > Would it be possible to patch gdk_window_set_cursor() and include fixed one > in greeters (eg. as __gdk_window_set_cursor() ) > and post fixed one on gnome's bugzilla? Yeah, I'll take a shot at a patch. If we end up modifying the greeters, though, I think it would be simpler to replace the call to gdk_window_set_cursor() with a call to XDefineCursor(). The implementation of gdk_window_set_cursor() is gnarlier than you might think, since it deals with alternative windowing systems (Win32, Wayland, HTML5, etc.) and stuff. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1024482 Title: Mouse cursor theme does not change from default after login Status in Light Display Manager: Confirmed Status in “lightdm” package in Ubuntu: Confirmed Status in “lightdm” package in Debian: Confirmed Bug description: When using LightDM to login to a GNOME Shell session, the mouse cursor's appearance does not change from what it is in the lightdm login screen (black pointer from default X theme). Any custom mouse cursor theme actually does apply within any open application windows, but hovering the cursor over the window title bar, the root window, or the Shell interface changes it back to the default black pointer, leading to an inconsistent appearance.
