Description Geoffrey Marr 2021-02-14 19:53:25 UTC 
Created attachment 1756998 [details]
output of "lspci -vvnn"

Description of problem:
After recently installing and attempting to boot Fedora-Workstation-Live-x86_64-34-20210210.n.1.iso, the system would hang after "Started GNOME Display Manager" was displayed. After disabling nouveau at grub (modprobe.blacklist=nouveau), the system boots as expected. Also tried Fedora-Workstation-Live-x86_64-34-20210212.n.0.iso and several older versions of Fedora Workstation Rawhide (0124) and (0128) and they exhibit the same result. This is on a Lenovo P53 with dual Intel and NVIDIA graphics (see lspci output attached below)

Version-Release number of selected component (if applicable):
Fedora-Workstation-Live-x86_64-34-20210210.n.1.iso
Fedora-Workstation-Live-x86_64-34-20210212.n.0.iso

How reproducible:
Every boot

Steps to Reproduce:
1. Install Fedora-Workstation-Live-x86_64-34-20210212.n.0.iso
2. Attempt to get to GNOME

Comment 2 Fedora Blocker Bugs Application 2021-02-14 19:58:52 UTC 
Proposed as a Blocker for 34-beta by Fedora user coremodule using the blocker tracking app because:

 Violates the Beta criterion:

"No part of any release-blocking desktop's panel (or equivalent) configuration may crash on startup or be entirely non-functional."[0]

I am choosing this criterion as when the system is stuck trying to get into GNOME, accessing the virtual terminals still allows logging in and using the system, just not graphically.

Installed Fedora kernel-5.10.16-200.fc33.x86_64 and the problem goes away.

Note that this was a kernel downgrade, as I installed an F33 kernel on F34.

There's a new kernel on fc34 repository: 5.11.0-156
You might want to upgrade and see if it solves your problem.

Seems to work! Tested both by installing the 5.11.0-156 kernel on the existing installation and by installing Fedora-Workstation-Live-x86_64-34-20210222.n.0.iso. No longer hangs on boot, boots to system Wayland GUI.
