[Bug 1232804] Re: Improve login greeter - desktop transition in Xubuntu
I just linked a branch which contains half of the fix for this (the other half needs to be implemented in xfwm4). This also fixes the greeter from leaking X11 resources all over the place. ** Branch linked: lp:~a-j-buxton/lightdm-gtk-greeter/experimental -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1232804 Title: Improve login greeter - desktop transition in Xubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm-gtk-greeter/+bug/1232804/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

https://github.com/ali1234/xfwm4/commit/b7baa7aa60cdb80759e0872d0ab5a7cb59ec5c10 This patch combined with the xsetroot patch for lightdm (above) fixes the issue, but isn't ideal, as it doesn't address the leaking pixmaps and non-standard atom use. It's along the general lines of what we need to do though. Specifically my patch enables the root pixmap copy only at startup, and not the rest of the monitoring code. The monitoring code is what makes xfdesktop crash, because when it uses RetainPermanent, but does not create the pixmap with a dummy X11 connection like it should. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1232804 Title: Improve login greeter - desktop transition in Xubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm-gtk-greeter/+bug/1232804/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1232804] Re: Improve login greeter - desktop transition in Xubuntu
So after massive amounts of investigation this is what I came up with: 1. lightdm-gtk-greeter uses RetainPermanent pixmaps to set the background. What this means is that it opens a second connection to the X server, allocates the pixmap as RetainPermanent, pushes it into the root window, and then closes the connection. Usually when a client disconnects all resources get deallocated, but RetainPermanent prevents this, so the pixmap stays. This is a widely used technique, but lightdm-gtk-greeter does not implement it in the standard way. usually when you do this you also set atoms pointing at the pixmap so that other programs can later change or deallocate those pixmaps - otherwise they just get leaked. lightdm-gtk- greeter does not do this. It should. 2. Xfwm4 starts up in compositing mode. All the composited windows are drawn into a buffer, then the buffer is drawn to the root window. This means that even if there's no windows on screen, the buffer will still draw over whatever pixmap is in the root window. At startup, Xfwm4 fills it's buffer with solid grey, so that's what you see. Xfwm4 has code to read out the root pixmap set using RetainPermanent, but again, it seems to be a none standard implementation which uses wrong atom names to get the pixmap addresses. This should also be fixed. Also this code is usually disabled as it is used in monitoring mode, when xfwm4 will constantly check if the root pixmap changed and copy the new one to it's composite buffer. We don't need to do that because xfdesktop handles our background. We only need to copy once, at startup, to fill the gap.
