Hi All, Under Fedora 29 (xserver-1.20) the transition from GDM to the GNOME3 session is no longer smooth, it seems that the screen is cleared to black when the Xserver starts instead of inheriting the framebuffer contents from GDM as before.
Changing the DDX driver from modesetting to intel fixes this, I think this may be caused by the new atomic support in the modesetting driver. Note if you try to reproduce this on Fedora 29 recent gdm versions also have some issues (*) which cause the transition to be non smooth it is best to downgrade gdm to 3.28.x (from koji) and then try with the intel ddx vs the modesetting ddx to clearly see the difference. Regards, Hans *) These are mostly fixed, but not entirely yet, see: https://gitlab.gnome.org/GNOME/gdm/merge_requests/45 _______________________________________________ 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
