What we've worked out so far (with thanks to Zbyszek) is basically this: 1. When you update systemd-udev , it restarts systemd-udev-trigger.service in %post 2. That calls `udevadm trigger --type=devices --action=add` 3. That seems to result in the video adapter effectively being replugged at the udev level Now on *most* systems, this seems to just cause X to (metaphorically) blink, go "what the hell happened there?", shrug, and carry on. If your system is one of these, you won't really notice anything. On affected systems, however - which so far seems to be something like 'some systems with NVIDIA adapters, possibly ones with NVIDIA/Intel hybrid graphics' - it causes X to crash. If you want to check if your system is affected you can just run 'systemctl restart systemd-udev-trigger.service' as root with a desktop running, and see if it crashes. Make sure you don't have anything running unsaved. :P -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
