Description František Zatloukal 2018-03-27 16:06:12 UTC 
Description of problem:
I've tried booting Fedora with "nomodeset". GNOME failed to load (in BIOS mode, UEFI worked just fine) on one of two tested (bare metal) desktops.

Version-Release number of selected component (if applicable):
gdm-3.28.0-6.fc28.x86_64
mesa-dri-drivers-18.0.0-0.3.rc4.fc28.x86_64

How reproducible:
Always(?)

Steps to Reproduce:
1. Boot Fedora with nomodeset


Actual results:
After logging in, screen stays with grayish (gdm) background with no content.

Expected results:
GNOME should work with VESA driver.

Comment 3 Lukas Ruzicka 2018-04-04 12:15:28 UTC 
I have tested today with the latest build (https://kojipkgs.fedoraproject.org/compose/branched/Fedora-28-20180403.n.0/compose/Everything/x86_64/iso/Fedora-Everything-netinst-x86_64-28-20180403.n.0.iso) and the installation was working on our bare metal. There were some blinking and glitching of the screen, but finally it was able to set up and display everything correctly.

bře 27 16:20:54 localhost.localdomain gnome-shell[1319]: Failed to create backend: Could not find a primary drm kms device
bře 27 16:20:55 localhost.localdomain gnome-session[1275]: gnome-session-binary[1275]: WARNING: App 'org.gnome.Shell.desktop' exited with code 1

This should be fixed in mesa 18.0.0-4.fc28.
