So far it looks that this set of updates killed my X quite thoroughly. An attempt to start it end up with a dead screen and stopping X does not help. Only a reboot forces re-initialization of a screen by BIOS. A keyboard is still operational as I can reboot from it "in blind". In logs I see at the bottom: (II) RADEON(0): [drm] register handle = 0xfce00000 (II) RADEON(0): [dri] Visual configs initialized Backtrace: and that is all. Backing off the previous version of xorg-x11-drv-ati does not help. Oh, I see, already reported. https://bugzilla.redhat.com/attachment.cgi?id=296273r Just added some hints how to avoid that bug.
