What do you mean by that? What the udev and logind does is to get user access to input devices and also to support SETMASTER/DROPMASTER when taking over framebuffer, right? Only the input part is handled by logind is being privileged entity that can be used to take over framebuffer -- nothing for udev to do. -- Piotr. pEpkey.asc Description: application/pgp-keys ___ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: https://lists.x.org/mailman/listinfo/xorg-devel

What do you mean by that? What I mean by that is that the Xserver probe code is already suffering from a combinatorial explosion (https://en.wikipedia.org/wiki/Combinatorial_explosion) problem wrt all the different options, hardware configs and paths through the code. So I do not want to add yet another variable. You are free to use the logind integration without udev support and with a small *local* downstream patch you may even be able to completely build without udev support while using the logind integration. But this is not something which I believe we should support in the upstream xserver, so if it breaks you get to keep both pieces.
