Comment: Upstream comment: "The problem with using gdm_wm_focus_new_windows is that this turns on the focus_new_windows flag and this never gets turned off. You'll notice this is normally only used when a pop-up is going to be displayed. Actually this seems sort of broken to me. Do we want gdmlogin and gdmgreeter to always just make focus go to the last window displayed? If so we could perhaps rip out all the gdm_wm_focus_window calls and just put a single gdm_wm_focus_new_window (TRUE) call in there. But, this does seem strange. If you have a bit of time, I would appreciate if you could look into this a bit furter so we could understand what is going on here. Since these calls are after the gtk_widget_show_all and gtk_widget_show_now calls, I'd expect that the window would be mapped. Also, I notice that gui/gdmlogin.c has pretty much the same gdm_wm calls, but people only seem to complain about this problem with gdmgreeter. Do you notice the same problem in gdmlogin? I'm assuming you can also debug the gdmwm code and see if the window is also unmapped there when the gdm_wm_focus_window call is made? If we see the problem in both programs, then I'd be happier fixing the code as you suggest in your patch. When you say the window is unmapped do you mean it isn't drawn to the screen or the gdmwm code doesn't seem to know about the window yet? Note that gdm_wm_init calls add_all_current_windows() and this should notice the window, and add it to the list. If this is failing, then perhaps there is a race condition where the window's MapNotify event is happening after the call to gdm_wm_focus_window. You could probably test this by putting a breakpoint in the event_process function and see if the code has already passed the gdm_wm_focus_window function by this time. If this is the problem, I'd lean towards just setting focus_new_windows to TRUE all the time, because I'm not sure how we could better manage the race condition. It would seem weird to make gdmgreeter wait for the MapWindow call before callng gdm_wm_focus_window." -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
