Description Richard Geary 2015-10-18 14:30:14 UTC

Description of problem:
After upgrading from Fedora 21 to 23 with dnf, the system did not boot.  It would hang at the "Switching Root" stage of the boot process, and the screen would flicker to a black screen & back

Version-Release number of selected component (if applicable):
Fedora 23

How reproducible:
Every time

Steps to Reproduce:
1. Install Fedora 21 + proprietary nvidia drivers 352.30 with Geforce GTX 460
2. Upgrade to Fedora 23 without removing nvidia drivers
3.

Actual results:
Hang at boot

Expected results:
dnf upgrade to fail and tell me to change to nouveau
Even better, dnf system-upgrade could provide instructions on how to remove nvidia (which includes unblacklisting nouveau)

Comment 1 Will Woods 2015-10-19 18:25:08 UTC

All dnf system-upgrade does is install packages; it's up to the package owners to make sure the packages actually work. I don't own nvidia's driver packages, so I can't really fix problems they cause.

This is something you should probably talk to nvidia about.
